The brain is made up of two cell types

Brain organize and coordinated in large part, movement, behavior and homeostatic body functions such as heartbeat, blood pressure, body fluid balance and body temperature. The brain is also responsible for functions such as recognition, emotion. memory, motor learning and all other forms of learning.

The brain is made up of two cell types: glia and neurons. Glia function to support and protect neurons, whereas neurons carry information in the form of electrical pulses known as action potentials. They communicate with other neurons and throughout the body by sending various kinds of chemicals called neurotransmitters. Neurotransmitters are delivered in a gap, known as synapses. Invertebrates such as insects may have millions of neurons in the brain, large vertebrates can have up to one hundred billion neurons.

The human brain is the central structure of the arrangement which has a volume of approximately 1.350cc and consists of 100 million nerve cells or neurons. The human brain is responsible for setting the whole body and human mind. Therefore there are close links between brain and mind. Brain and nerve cells in it is believed to affect human cognition. Knowledge about the brain affect the development of cognitive psychology.
