and i’ve mentioned this before but the common conception that ppl who constantly suffer become desensitized to suffering is perfectly wrong. ppl who experience repeated psychological and physiological stressors, esp in childhood, actually become more responsive to stress, w stress response systems in the brain & body getting increasingly sensitive to stimuli and having more prolonged/exaggerated reactions  

what doesn’t kill you does not make you stronger, it makes you sicker and less able to cope biologically and emotionally w additional hardship

“The deep history of egg color re­mains unknown. Some scientists think the dinosaur ancestors of birds pro­duced only white eggs, as reptiles still do today, and that pigmentation came later. Others suggest dinosaur eggs could have been blue.”

“Scientists say some species get away with laying conspicuous eggs because the parents sit tightly on the nest, with both male and female sharing round-the-clock incubation duty so the eggs are almost never exposed to view. In fact, another novel, though disputed, explanation for brightly colored, conspicuous eggs is called the “blackmail theory.” Bucknell University’s Daniel Hanley has theorized that, because conspicuous eggs are at greater risk of predation, females may lay them to blackmail their mate into more active participation at the nest. If the male wants the showy eggs to stay covered up and protected, he must take turns incubating on the nest himself or bring food to the female so she can stay on the nest.”

On a hot surface, droplets can float on a layer of their own vapor and vibrate in star-like shapes. These so-called Leidenfrost stars also make noise, with distinct beats that match the oscillations of the vapor layer beneath them. (Image and research credit: T. Singla and M.

rsd is not a condition. rsd is not a diagnosis. rsd is not a medically recognized symptom of adhd and the experience “rsd” describes is not exclusive to adhd at all. this does not mean people with adhd can’t experience rejection sensitivity, but “rsd” as an “adhd” thing is a concept with no emprical backing developed by one man, with claims of it being brain-based without any evidence behind that claim, as well as many other claims surrounding the “nature” of rsd. adhd is a condition characterized by executive dysfunction, which can involve emotional dysregulation, but acknowledging that is different from the framework of “rsd” and seeing people on this site pass this around without critical thought and even claiming rsd is “adhd only >:(” makes me sick. you’re buying into what’s basically pop psychology instead of scientific research.

emotional dysregulation and rejection sensitivity is by no means adhd exclusive, and people with adhd experiencing those things doesn’t need to have its own special label or whatever when there’s no meaningful difference between someone with adhd experiencing those things and someone without adhd experiencing those things. that’s not logical and a ridiculous mentality of “rsd is adhd ONLY because our rejection sensitivity is SPECIAL” completely goes against building common ground with other neurodivergent people for petty and invalid reasons.

the amount of misinfo going around about adhd on this site is uncanny. please investigate claims others make about disability and do your research - actual research, which doesn’t include tumblr posts that lack citation and oft unreliable sources like ADDitude Mag and WebMD. it would be INFINITELY more productive to operate on a shared experience of emotional dysregulation and rejection sensitivity among varying groups of neurodivergent people than to feed into this nonsensical idea of “adhd-only special super rejection sensitivity.”

Torus Configurations

Human consciousness is characterized by awareness, volition and cognitive reflection, operating within a neural workspace…Within this workspace, a bicyclic flow of information was envisioned…Both types of information flow provide the basis for integration of active information that returns to itself (a modality of self-consciousness), including modalities of universal consciousness.

Toroidal information flux is postulated by us to provide the basis for the existence of consciousness at the different scales of the Universe. There are distinct reasons to choose the multidimensional symmetrical aspects of the double vortex torus, a geometry that may mimic a combination of transversal, longitudinal and circular waves.

—Dirk Meijer & Hans Geesink, Consciousness in the Universe is Scale Invariant and Implies an Event Horizon of the Human Brain

superb fairy wrens & cuckoo coevolution (the og among us game)

bio 180 lec29 mutalism and coevolution (lecture by prof herron)

“cuckoo chicks develop very quickly and they tend to hatch out early. they often hatch out before their foster siblings of the host species hatch out. and in many species of cuckoo, the first thing the cuckoo chick does when it hatches out of the egg, before it grows any feathers, before its eyes are open, it lifts those foster sibling eggs (the fairy wren eggs) and heists them right out of the nest and chucks them onto the ground.” (see image below)

Natural speech reveals the semantic maps that tile human cerebral cortex

interactive 3d semantic map

paper

Here we systematically map semantic selectivity across the cortex using voxel-wise modelling of functional MRI (fMRI) data collected while subjects listened to hours of narrative stories. We show that the semantic system is organized into intricate patterns that seem to be consistent across individuals. We then use a novel generative model to create a detailed semantic atlas. Our results suggest that most areas within the semantic system represent information about specific semantic domains, or groups of related concepts, and our atlas shows which domains are represented in each area. This study demonstrates that data-driven methods—commonplace in studies of human neuroanatomy and functional connectivity—provide a powerful and efficient means for mapping functional representations in the brain.
