The cochlea, a structure in the inner ear, changes sound waves into electrical signals that get sent to the brain. The cochlea also determines the pitch of sounds. more...
New Neuronal Growth in the Adult Brain
By: David Olle
New neurons continue to form in the adult brain. Challenging mental exercises help to maintain these neurons and to improve brain cognitive function. more...

Once light enters the eye, its message is sent to a number of brain parts. These places in the brain construct pictures and tell the body how to respond. more...
How Eyes Tell the Brain What They "See"
By: Andy Luttrell
When light enters the eye, specific neurons in the retina must respond to the information and send a message to the brain. This is a process called "phototransduction." more...
The Neurology of Pain Perception
By: Andy Luttrell
Feelings of pain are processed differently than other senses. This article explains the basic neurological processing of pain, including pain receptors and brain regions. more...

Neurons communicate with their target cells by sending signals down their axon. In order to speed conduction of the signal many axons are myelinated. more...
How Balance and Posture Are Maintained
The fact that human beings that can stand upright and move around in the environment is due to a remarkable system of information collection and integration. more...
