Do dogs have an area of the brain for recognizing human faces? What about other dog's faces? Or do they recognize you by scent more than by face? What's the neuroscience and psychology behind the inter- and intra-species recognition among dogs? Not sure what flair to use for this...
Research trials explored a minimal groups paradigm and also religious affiliation for grounds of in-group and out-group formation correlated with fMRI. Participants were shown hands either being touched or hurt labelled as in group or out group hands.
The discussion within this article is fascinating and has huge implications for better understanding allyship, apathy and out-group derogation in our increasingly polarised global landscape.

When the profoundly blind people use their sense of touch to "see" someone's face, is there action in the FFA? I know there are other centers of the brain to receive touch signals, but my question is specific to the FFA.
Like the method of loci which employs our super-efficient spatial memory to create associations, is there potential for the Fusiform Face Area to help us encode non-face information?
Humans are insanely good at remembering faces, and there are even “super-recognizers” out there who can instantly and accurately identify a face they’ve only seen once, many many years ago. Many work in law enforcement.
So could it be possible to utilize this brain region’s power to retrieve/encode things like, say, the exact details of a painting? Is its use limited to visual information only? As a side question, what are its limits as to what it considers a “face”? If I stared at an image of a face and watched as its features morphed into something else entirely, at what point would I stop being able to recognize that image with pinpoint accuracy?
Do your worst!
Hey y'all,
alright, I've decided to make this post, after reading dozens of pessimistic posts/comments in this sub, first of all, guys stop it, no one should talk about duration, cause, or mechanisms behind tinnitus without having clinical data, medical theories, studies etc..
- Note, this information is based on my own experience as an neurologist (still studying btw..)
Alright, I've gathered alot of information about pathophysiology and mechanisms behind tinnitus, from talking to experts, researchers, neurologists, neurotologists etc...
-----------------------------------------------------------------------------------------------------------------------------------------------------
The neuropathophysiological mechanism behind tinnitus is very complex and is still "theoretic" in some parts, but I've tried my best to evaluate and educate everyone about it. (As best as I can).
Alright let's start.
-----------------------------------------------------------------------------------------------------------------------------------------------------
The model and pathophysiology in terms of development of tinnitus is based on a framework called Thalamocortical dysrhythmia, I'll explain in detail rn, it's an ex-inhibition problem within your thalamus (thalamic area), so first of all we need to understand how we process nerve signals, this is purely based on neurochemical-electrical impulses that arrive and get (s) transmitted with 250MpH/400KmH, this happens with the help of various neurotransmitters that are controlling the ex-inhibition threshold aka action potential.
Alright let's move on,
Our Thalamus is basically an relay station, that receives and controls all information (nerve input) arriving into primary cortical areas, aswell as it transmits information down the spinal cord, this is why it's called the "gatekeeper of the brain"
