Hippocampus plays an important role in the formation of long term memory, and thus is required
for learning. Cerebrum is the largest part of the brain and is divided into two halves, called cerebral
hemispheres. These halves communicate with each other by means of a large band of axons, called
corpus callosum.

About This Channel.....................
I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
