See posts from people saying things like "If i can do this, so can you!''

What if we can't? What if we can't learn a new sport, what if we can't be valedictorian of our school? what if we can't learn a new language? what if we can't excel in some areas? What if we can't?

Your posts about "Oh i did this so you can definitely too" are plain weird because i bet someone read that and CAN'T do the things you're saying they can. Stop it. Just stop with your takes. Maybe look at a bigger picture.

neurodivergencies* are just as physical as other disabilities. why are changes in your brain, nerves, gut, hormones, senses, and energy levels only considered physical if they're caused by literally anything else? have we considered that the separation of the mind from the rest of the body is just a way of minimizing and othering ND people?

*neurodivergent refers to people with mental illnesses, developmental and intellectual disabilities, and other neurological conditions.

I’m impatient about getting in with a concussion specialist, and can’t find what I’m looking for with a google search, so…

Anyone with PCS or who has had PCS (post-concussion syndrome) know if writing fiction is bad for you, or when you can do it again? I’m overrun by writing ideas here and the frustration of not writing them is really getting to me.

Hot Head

If I asked you what the average body temperature is, you’d probably say around 37°C. The brain’s temperature is generally assumed to be the same, despite its much higher workload. Much like components of your phone heat up when working harder, researchers have found that the same can be said for our brains, which run hotter than previously thought. Using a technique called magnetic resonance spectroscopy, the team measured brain temperatures of people throughout the day. Average temperatures for different regions are shown using coloured blocks where dark purples are coolest and yellows are highest. Brain temperatures varied throughout the day being warmer in the morning (left) and afternoon (middle), and cooler at night (right). Female brains (top row) were warmer than male brains (bottom row), and the team also found differences with age and the menstrual cycle. This has major implications for how we diagnose and manage several brain disorders.

Covid’s Harmful Effects on the Brain Reverberate Years Later

Study finds ongoing risk of psychotic disorders and dementia

Research highlights burden of pandemic-induced chronic disease

By

Jason Gale

August 17, 2022 at 3:30 PM PDT

Covid-19 survivors remain at higher risk of psychotic disorders, dementia and similar conditions for at least two years, according to a large study that highlights the mounting burden of chronic illness left in the pandemic’s wake.

While anxiety and depression occur more frequently after Covid than other respiratory infections, the risk typically subsides within two months, researchers at the University of Oxford found. In contrast, cognitive deficits known colloquially as “brain fog,” epilepsy, seizures and other longer-term mental and brain health disorders remained elevated 24 months later, according to a study published Wednesday in the journal Lancet Psychiatry.

The findings, based on the records of more than 1.25 million patients, add to evidence of the virus’s potential to cause profound damage to the central nervous system and exacerbate the global burden of dementia -- which cost an estimated $1.3 trillion in the year the pandemic began. Oxford researchers showed in March that even a mild case is associated with brain shrinkage equivalent to as much as a decade of normal aging.

“The results have important implications for patients and health services as it suggests new cases of neurological conditions linked to Covid-19 infection are likely to occur for a considerable time after the pandemic has subsided,” said Paul Harrison, a professor of psychiatry and the study’s lead author, in a statement. The work highlights the need for more research to understand why this happens, and what can be done to prevent and treat these conditions, he said.

Copypasta from Twitter

So I'm doing a thing. I'm not good at words so bear w/me please.

Some of you have heard me refer to having a “brain disorder” or calling my brain stupid/broken. I've never really shared the details on that.

CW: Trauma, Sexual Assault, Violence (little detail as possible)

When I was a young bloke, I was dating someone who was abusive. I knew this before I even got involved with him but he gave me attention and convinced me that he "really saw me." My complicated past had taught me I was unlovable so I took the bait. Being autistic, I've always been easy to manipulate, so he had the ideal person to bully. At the time, I hadn't ever slept with anyone before. I was still figuring myself out (had never heard of ace folks being a thing) and wasn't ready yet.

One day he decided that he had had enough of me saying no to him. Not surprisingly, he attacked me, hitting me in the chin so hard with something it split open and made me blind and confused. He forced himself on me, then stabbed me 4 times in my lower torso. Needless to say I had a lot of damage, one of which was a concussion, but with no help to come for over 15m, it got worse as I passed out. I'm turn I suffered a traumatic brain injury (TBI). This is what I've been vaguely referring to when I use those other terms.

TBIs can cause many different issues, but mine causes:

-A lisp

-A limp

-Minimal fine motor skills (can't button buttons, pick up small stuff, or hold a pencil, etc)

-Decreased gross motor skills

-Memory issues (long and short; loss and forgetting)

-Vision issues

-Occasional confusion/disorientation

-Inability to retain new information/skills I've learned

-Difficulty with social situations and relationships

Some of these are constant, some aren't and can get better or worse by day (heck sometimes by minute; no idea why).

Some things that help me are:

-Finding ways to do things differently. Cheats and hacks!!

-Writing LOTS of lists to remind me how to do simple stuff or of tasks I need to complete.

-Using assistive technology and mobility aids.

-People being patient with me (big one).

I don't have pity for myself. I've done AMAZING things that I'm grateful for, and could have ended up so much worse.

I got to travel the world and fall in love at least twice.

So yeah, now I mostly make posts on Twitter about politics from my chair bc I can't physically get out there to march and canvas, and generally raise Hell, without help that I don't have.

Or I'm filling my TL with David Tennant pics, stuff about being queer, disabled and autistic or general silliness. My life isn't as “big” as I'd hoped and I'll probably never meet anyone to spend my life with. I struggle with that sometimes, more than I'd like to admit, but in the grand scheme of things, I'm doing pretty damn good. I'm grateful for the community I've found here in recent years, especially since 90% of days, you're my only human contact.

Love y'all. Thank you for listening. 💜

i used to be so good at writing strong, thoroughly-researched, thoroughly-edited essays.

as a kid in hs, my teacher literally came up to me, holding my 40 page essay on the intersection of the European witch hunts and capitalism/exploitation/gender roles (it was supposed to be 7 pages...whoops) and went like "this is literally a master's-degree level thesis. what are you doing?? you could literally use this as your final dissertation in a master's program, what the fuck."

NOW??? NOW?? you'd think I'd be oh so skilled. but alas. i can barely piece together two ideas. adhd skill-regression is so so real. im SOBBING

if you think that disabled people who arent contributing anything to society are leeches then you are Ableist. Disabled people who arent able to contribute much, or anything to an already fucked up society are worth it and are amazing. Disabled people with higher support needs are told constantly about everything wrong with them instead of being told about everything thats right with them. How about instead of constantly tearing disabled people down, you instead love them because they’re HUMAN.

I see time and time again. “Go outside and do something. Everyone can do SOMETHING.” What if they cant? WHAT. IF. THEY. CANT? Then what? They arent worth any less. They arent moochers, or leeches, or anything like that. They are disabled. Stop being ableist, take disabled people into account with your language because your privilege shows.

seeing people my age talk about how scared they are of memory loss, which they only associate with old age, is so surreal to see as a 24 year old who has actively experienced memory loss for a long time now

there are causes for memory loss besides dementia and alzheimer’s, i hope y’all know that. dissociative disorders, trauma, brain injuries, thyroid problems, even just stress and lack of sleep can fuck up your ability to store, process, and access memory. and that’s just a few of the many causes i can think of off the top of my head right now.

please stop treating disabled people like some scary “other” that you might become only in the distant, decades-away future. we are your age, too. you may become one of us sooner than you know. stop acting like memory loss marks the end of a life, when so many of us have so much living left to do!

Study Reveals a Universal Pattern of Brain Wave Frequencies - Technology Org

New Post has been published on https://thedigitalinsider.com/study-reveals-a-universal-pattern-of-brain-wave-frequencies-technology-org/

Study Reveals a Universal Pattern of Brain Wave Frequencies - Technology Org

Throughout the brain’s cortex, neurons are arranged in six distinctive layers, which can be readily seen with a microscope. A team of MIT and Vanderbilt University neuroscientists has now found that these layers also show distinct patterns of electrical activity, which are consistent over many brain regions and across several animal species, including humans.

The researchers found that in the topmost layers, neuron activity is dominated by rapid oscillations known as gamma waves. In the deeper layers, slower oscillations called alpha and beta waves predominate. The universality of these patterns suggests that these oscillations are likely playing an important role across the brain, the researchers say.

“When you see something that consistent and ubiquitous across cortex, it’s playing a very fundamental role in what the cortex does,” says Earl Miller, the Picower Professor of Neuroscience, a member of MIT’s Picower Institute for Learning and Memory, and one of the senior authors of the new study.

Imbalances in how these oscillations interact with each other may be involved in brain disorders such as attention deficit hyperactivity disorder, the researchers say.

“Overly synchronous neural activity is known to play a role in epilepsy, and now we suspect that different pathologies of synchrony may contribute to many brain disorders, including disorders of perception, attention, memory, and motor control. In an orchestra, one instrument played out of synchrony with the rest can disrupt the coherence of the entire piece of music,” says Robert Desimone, director of MIT’s McGovern Institute for Brain Research and one of the senior authors of the study.

André Bastos, an assistant professor of psychology at Vanderbilt University, is also a senior author of the open-access paper, which appears in Nature Neuroscience. The lead authors of the paper are MIT research scientist Diego Mendoza-Halliday and MIT postdoc Alex Major.

Layers of activity

The human brain contains billions of neurons, each of which has its own electrical firing patterns. Together, groups of neurons with similar patterns generate oscillations of electrical activity, or brain waves, which can have different frequencies. Miller’s lab has previously shown that high-frequency gamma rhythms are associated with encoding and retrieving sensory information, while low-frequency beta rhythms act as a control mechanism that determines which information is read out from working memory.

His lab has also found that in certain parts of the prefrontal cortex, different brain layers show distinctive patterns of oscillation: faster oscillation at the surface and slower oscillation in the deep layers. One study, led by Bastos when he was a postdoc in Miller’s lab, showed that as animals performed working memory tasks, lower-frequency rhythms generated in deeper layers regulated the higher-frequency gamma rhythms generated in the superficial layers.

In addition to working memory, the brain’s cortex also is the seat of thought, planning, and high-level processing of emotion and sensory information. Throughout the regions involved in these functions, neurons are arranged in six layers, and each layer has its own distinctive combination of cell types and connections with other brain areas.

“The cortex is organized anatomically into six layers, no matter whether you look at mice or humans or any mammalian species, and this pattern is present in all cortical areas within each species,” Mendoza-Halliday says. “Unfortunately, a lot of studies of brain activity have been ignoring those layers because when you record the activity of neurons, it’s been difficult to understand where they are in the context of those layers.”

In the new paper, the researchers wanted to explore whether the layered oscillation pattern they had seen in the prefrontal cortex is more widespread, occurring across different parts of the cortex and across species.

Using a combination of data acquired in Miller’s lab, Desimone’s lab, and labs from collaborators at Vanderbilt, the Netherlands Institute for Neuroscience, and the University of Western Ontario, the researchers were able to analyze 14 different areas of the cortex, from four mammalian species. This data included recordings of electrical activity from three human patients who had electrodes inserted in the brain as part of a surgical procedure they were undergoing.

Recording from individual cortical layers has been difficult in the past, because each layer is less than a millimeter thick, so it’s hard to know which layer an electrode is recording from. For this study, electrical activity was recorded using special electrodes that record from all of the layers at once, then feed the data into a new computational algorithm the authors designed, termed FLIP (frequency-based layer identification procedure). This algorithm can determine which layer each signal came from.

“More recent technology allows recording of all layers of cortex simultaneously. This paints a broader perspective of microcircuitry and allowed us to observe this layered pattern,” Major says. “This work is exciting because it is both informative of a fundamental microcircuit pattern and provides a robust new technique for studying the brain. It doesn’t matter if the brain is performing a task or at rest and can be observed in as little as five to 10 seconds.”

Across all species, in each region studied, the researchers found the same layered activity pattern.

“We did a mass analysis of all the data to see if we could find the same pattern in all areas of the cortex, and voilà, it was everywhere. That was a real indication that what had previously been seen in a couple of areas was representing a fundamental mechanism across the cortex,” Mendoza-Halliday says.

Maintaining balance

The findings support a model that Miller’s lab has previously put forth, which proposes that the brain’s spatial organization helps it to incorporate new information, which carried by high-frequency oscillations, into existing memories and brain processes, which are maintained by low-frequency oscillations. As information passes from layer to layer, input can be incorporated as needed to help the brain perform particular tasks such as baking a new cookie recipe or remembering a phone number.

“The consequence of a laminar separation of these frequencies, as we observed, may be to allow superficial layers to represent external sensory information with faster frequencies, and for deep layers to represent internal cognitive states with slower frequencies,” Bastos says. “The high-level implication is that the cortex has multiple mechanisms involving both anatomy and oscillations to separate ‘external’ from ‘internal’ information.”

Under this theory, imbalances between high- and low-frequency oscillations can lead to either attention deficits such as ADHD, when the higher frequencies dominate and too much sensory information gets in, or delusional disorders such as schizophrenia, when the low frequency oscillations are too strong and not enough sensory information gets in.

“The proper balance between the top-down control signals and the bottom-up sensory signals is important for everything the cortex does,” Miller says. “When the balance goes awry, you get a wide variety of neuropsychiatric disorders.”

The researchers are now exploring whether measuring these oscillations could help to diagnose these types of disorders. They are also investigating whether rebalancing the oscillations could alter behavior — an approach that could one day be used to treat attention deficits or other neurological disorders, the researchers say.

The researchers also hope to work with other labs to characterize the layered oscillation patterns in more detail across different brain regions.

“Our hope is that with enough of that standardized reporting, we will start to see common patterns of activity across different areas or functions that might reveal a common mechanism for computation that can be used for motor outputs, for vision, for memory and attention, et cetera,” Mendoza-Halliday says.

What Is PET Scan ?

A PET scan (positron emission tomography) is a type of imaging test that uses a radioactive tracer to look for changes in the function of cells and tissues. A tracer is a substance that is introduced into the body to make it easier to see certain areas or organs. The radioactive tracer used in PET scans emits positrons, which are tiny particles that collide with electrons in the body. This creates gamma rays that can be detected by a scanner and used to create images of the inside of the body. PET scans are often used to diagnose cancer because tumor cells typically have higher levels of activity than normal cells. They can also be used to check for treatment response, measure tumor size, and identify new tumors.
