White matter is vast, intricate network of cables that connects different regions of brain, allowing them to communicate and coordinate. If the brain were a corporation, grey matter would be the individual offices where decisions are made, and white matter would be the high-speed fiber-optic cables connecting them all together. What Exactly is White Matter? … Read more
If the human brain is high-powered computer network, gray matter is CPU and hard drive. It is a real, physical component of our central nervous system that serves as engine for our thoughts, movements, and perceptions. What Exactly is Gray Matter?

Structure Cerebrum is divided into two halves: left and right cerebral hemispheres. They are connected by a thick bundle … Read more
Cerebrum divide into two part known as cerebral hemispheres, this structure serve for higher-level functions, including thought, memory, language, and voluntary movement. While they look like symmetrical mirror images, these two hemispheres are work together to create complex human experience. Anatomy and Connection Left and right hemispheres are separated by a deep groove called longitudinal … Read more
Anatomy Amygdala isn’t just one solid mass; it is a complex cluster of about 13 nuclei (groups of neurons) with distinct functions. It is part of limbic system, evolutionary ancient part of our brain responsible for behavioral and emotional responses.
