Brain’s Neuroanatomy 1

The human brain broadly divided into limbic cortex, cerebral neocortex.

Limbic cortex is mainly responsible for the output of instinctive affectivity (appetite, sleep drive, etc), motivation, control of autonomic nervous system (heart movement, breathing, etc), and memory.

Cerebral neocortex gets engaged in intellectual activities, sensation.

Now I explain about the relationship between the two areas.

Here is one example.
When one man exhibits a affectivity such as “I want to do something” , it is motivated by cingulate gyrus.

And then Cerebral neocortex considers “What should we do”.


After that, it asks to hippocampus in limbic cortex “Before, how did I do such situation?”

Hippocampus refers in a library in the brain and answer the question.

Then amygdala in limbic cortex decides the value.

Cerebral neocortex makes the program, and executes it.

The brain cerebration consists of such a process.
