Understanding the Human Brain
The human brain contains approximately 86 billion neurons connected through trillions of synapses. These networks form the foundation of every cognitive process.
Major Functions of the Brain
Memory Formation
Memory enables individuals to store and retrieve information. It influences learning, communication, relationships, and professional performance.
Attention and Focus

Maintaining these functions requires a healthy neurological environment supported by proper nutrition, adequate rest, and healthy lifestyle habits.
