Your selections: Brain Anatomy and Function
Processing information from the sensory systems is one of many functions of the brain. Such information is often the first step in other brain activities, including learning and retaining knowledge.

Often considered the most important sense for humans, hearing allows us to communicate with each other by receiving sounds and interpreting speech.
  • BrainFacts/SfN
Our best insights into how the normal brain ages come from long-term studies of the nervous system that began decades ago.

To be able to see anything, eyes first need to process light. Vision begins with light passing through the cornea.
  • BrainFacts/SfN
The moment light meets the retina, the process of sight begins. About 60 years ago, scientists discovered that each vision cell’s receptive field is activated when light hits a tiny region in the center of the field and inhibited when light hits the area surrounding the center.

The cerebrum, the largest part of the human brain, is associated with higher order functioning, including the control of voluntary behavior. Thinking, perceiving, planning, and understanding language all lie within the cerebrum’s control.

The two halves of the nervous system work together in order for your body to properly communicate its sensations and needs.
  • BrainFacts/SfN
Cells within the nervous system, called neurons, communicate with each other in unique ways. The neuron is the basic working unit of the brain.

Touch is the sense by which we determine the characteristics of objects: size, shape, and texture.
  • BrainFacts/SfN
The brain uses a variety of chemicals called neurotransmitters to communicate between brain cells.
  • BrainFacts/SfN
The brain uses some unconventional means to communicate.

Once the neural induction has occurred, the next step for new neurons is a journey to the proper position in the brain. This process is called migration, and it begins three to four weeks after a human baby is conceived.
