The circuits of the cerebral cortex
underly our ability to understand the world and interact with it.
The cerebral cortex
is the outer layer of the brain, and it plays a critical role in memory and language.
Notably, the sensory networks are missing -- vision, hearing and touch -- and only 20 percent of the cerebellum is devoted to movement, roughly the same amount as in the cerebral cortex
. The remaining 80 percent is occupied by networks involved in higher-order cognition: the attention network; the default network, which has to do with daydreaming, recalling memories and just idly thinking; and two networks that oversee executive functions such as decision-making and planning.

According to (https://news.vanderbilt.edu/2017/11/29/grumpy-cat-study-dogs/) Vanderbilt University , dogs have 530 million neurons in the cerebral cortex
- more than double the number cats have.
"For a long time, scientists used to believe the mammalian cerebral cortex
to be the anatomical cause of cognitive ability; it is made up of six cortical layers," said Sara Letzner from Ruhr-Universitat Bochum in Germany.
In a 2017 study, Ju Hwan Kim and Korean colleagues showed that radiofrequency electromagnetic fields (RF-EMF), such as radiation emitted by cell phones, activate autophagy in cerebral cortex
neurons and apoptosis in the brainstem cells of mice.
Instead, they made a tiny but powerful model of the cerebral cortex
for the study of such devastating human conditions as schizophrenia, epilepsy and autism - impairments not easily studied in people.
These molecules have allowed evaluating parameters as changes in the structure, number and distribution of neurons in the cerebral cortex
of rabies-infected mice.
The primary mechanism responsible for human cognitive abilities is the number of neurons in the cerebral cortex
. The human brain has more neurons in the cerebral cortex
(16 billion) than any other animal, even when the animal (African elephant) has 257 billion brain neurons.
Scientists at the University of Newcastle, working with colleagues in Brazil, found that as we age, tension on the cerebral cortex
- the brain's outermost layer - appears to decrease.
So he and colleagues mapped the activity of some 60,000 to 80,000 pea-sized regions across the cerebral cortex
in seven people who lay in a functional MRI machine and listened to stories from The Moth Radio Hour.
The present study examined the effect of ethanol abuse on the number of neurons and astrocytes in the rat cerebral cortex
. After 45 days of ethanol treatment (2 g/kg by intraperitoneal injection), tissue samples from the rat motor cortex were Nissl-stained and probed for glial fibrillary acidic protein (GFAP) expression.
There's no harm done, unless A) you once wrote soaps, and are thus rendered obsolete; or B) you have a functioning cerebral cortex
, which will struggle to buy this as anything other than unconvincingly manufactured melodrama.
The cerebral cortex
is one of the most complex structures in our brain.
