ANATOMY

Detailed explanation-1: -What is the brain? The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

Detailed explanation-2: -The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The central nervous system (CNS) is composed of the brain and spinal cord.

Detailed explanation-3: -Neurons release brain chemicals, known as neurotransmitters, which generate these electrical signals in neighboring neurons. The electrical signals propagate like a wave to thousands of neurons, which leads to thought formation. One theory explains that thoughts are generated when neurons fire.

Detailed explanation-4: -The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls movement, speech, intelligence, emotion, and what we see and hear.

Detailed explanation-5: -The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex ([link]). The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory.
