Memories are stored all over the brain, and it’s likely the prefrontal cortex that signals for their retrieval.
The act of remembering relies on the prefrontal cortex, which governs thought, attention, and reasoning.
When corticosteroids stimulate the amygdala, the amygdala inhibits, or lessens the activity of, the prefrontal cortex.
Moreover, when updating impressions based on people's behaviors, activity in the ventrolateral prefrontal cortex and the superior temporal sulcus correlates with perceptions of how frequently those behaviors occur in daily life.
The superhighway that carries pain information from the spinal cord to the brain is our sensing pathway that ends in the cortex, a part of the brain that decides what to do with the pain signal.
Your brain's visual cortex operates on assumptions about the lighting of this image.
After immediate sensory data is temporarily transcribed by neurons in the cortex, it travels to the hippocampus, where special proteins work to strengthen the cortical synaptic connections.
If the experience was strong enough, or we recall it periodically in the first few days, the hippocampus then transfers the memory back to the cortex for permanent storage.
But equally important was the accompanying evolution of the brain, with its expansion of the visual cortex to process the sharper and more colorful images it was receiving.
And these input signals coming from descending modulation from higher parts of the brain, like the motor cortex, the cerebellum, the basal ganglia, will all modulate activity of the spinal cord while we do locomotion.
It's much easier to implant electrodes in the motor cortex than in the spinal cord, because it's protected by the vertebrae.
Now, the prefrontal cortex, that youngest part of our brain from an evolutionary perspective, it understands on an intellectual level that we shouldn't smoke.
When the prefrontal cortex goes offline, we fall back into our old habits, which is why this disenchantment is so important.
Now, one current hypothesis is that a region of this network, called the posterior cingulate cortex, is activated not necessarily by craving itself but when we get caught up in it, when we get sucked in, and it takes us for a ride.
Too much of it results in the loss of synaptic connections between neurons and the shrinking of your prefrontal cortex, the part of your brain the regulates behaviors like concentration, decision-making, judgement, and social interaction.
And when they had reached a plateau of performance, we did a lesion in the motor cortex corresponding to the hand motion.
This affects areas like the limbic system, which oversees emotions, and your cerebral cortex, which is involved in reasoning.
One plausible candidate is the prefrontal cortex, which is involved in all complex cognitive functions.
Prefrontal cortex neurons are connected to the posterior cortex by long, spindly cell extensions called neural fibers.
The mental synthesis theory proposes that like a puppeteer pulling the strings, the prefrontal cortex neurons send electrical signals down these neural fibers to multiple ensembles in the posterior cortex.
This conscious purposeful synchronization of different neuronal ensembles by the prefrontal cortex is called mental synthesis.
The problem is that some neurons are much farther away from the prefrontal cortex than others.
This is most apparent with the outer layer, or the cortex.
However, only when we use the full, engaging, coherent story do the responses spread deeper into the brain into higher-order areas, which include the frontal cortex and the parietal cortex, and make all of them respond very similarly.
There, the somatosensory cortex processes them.
The entire body is mapped in this cortex.
The cortical homunculus is a model of the human body with proportions based on the size of each body part’s representation in the cortex, The amount of cortex devoted to a specific body part can grow or shrink based on how much sensory input the brain receives from that body part.
But this basic idea that visual cortex works like a series of computational elements that pass information one to the next in a cascade, is essentially correct.
But they lie way below the cortex, way below the limbic system where we feel our emotions, generate our emotions.
Your visual cortex takes up about 30 percent of your brain.
