The brain has a complicated anatomy. If you remove both left and right cerebral hemispheres of the brain, it exposes many other structures. Some of them have mass and are bigger like the thalamus and some are just a few nerve fibers inside of the larger structures and are only appealing to microscopes.
The brain's parts can be sorted in a few ways and in all of these systems, the cerebral cortex(wrinkled layer) is the dominant structure. The cerebrum is divided into 2 halves, the right and left hemispheres which are linked by nerve fibers. In between the brain contains the hippocampus, thalamus, hypothalamus, and the amyglada, all known as the diencephalon(in between brain). To the naked eye, most of the brain shows as "islands" of gray matter located inside the nerve fiber's white matter.
Thalamus:A major processing area for inputs to the cerebral cortex.
Amyglada: Part of the limbic system involved in learning and emotions.
Hippocampus: Another part of the limbic system which is deeply involved with short-term memory.

Nice write-up from some one your age, Pranav ! Keep it up .. Good Job! ... you can become a neuro-scientist one day. And, here is some food for thought:
ReplyDeleteThe brain we understand best are on its surface. Textbook picture of the brain shows its exterior structures and functions - visual cortex (vision), parietal lobe (attention and action planning), motor cortex (movement), temporal lobe (complex vision and audition), and so on.
Slice the brain down the middle like an avocado, you'll see another half: subgenual cingulum (function unknown), midcingulum (function unknown), medial parietal (function unknown), retrosplenium (function unknown), and posterior cingulate cortex (function truly unknown).
And that's about all we know for now !
Think about it and share your findings ....
Thanks for the information uncle, in fact I really do look forth into becoming a neurologist. Thanks again for the wishes.
