Cerebellum – Balance & Motor Control in Brain
The cerebellum, with its rich neural network, is the brain center responsible for motor control over voluntary muscles, muscle tone and maintenance of balance

The Sense of Smell
The olfactory system consists of a collection of odor receptors that send a message to the brain when they detect a smell. This is just one of the chemical senses.

How the Ear Works
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.

New Neuronal Growth in the Adult Brain
New neurons continue to form in the adult brain. Challenging mental exercises help to maintain these neurons and to improve brain cognitive function.

How Vision Works in the Brain
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.

|
How Eyes Tell the Brain What They "See"
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."

The Neurology of Pain Perception
Feelings of pain are processed differently than other senses. This article explains the basic neurological processing of pain, including pain receptors and brain regions.
|
|
Sensory Receptors
Sensory receptors send impulses to the brain regarding the environment in and around the body.
|
|
How the Retina Works
The ability to see begins with light entering the eye and the processing of visual signals by a highly interconnected series of specialized neurons.
|
|
What Is Myelin?
Neurons communicate with their target cells by sending signals down their axon. In order to speed conduction of the signal many axons are myelinated.
|
|
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.

|
Glial Cells in the Brain
Glial cells form the scaffolding of the brain and help keep neurons alive, yet the importance of glia is often overlooked.

Understanding the Human Brain
The brain is one of the most complicated organs in the body and also one of the most poorly understood today.

Is a Wandering Mind a Bad Thing?
Everyone daydreams but is it something to be ashamed of? New research reveals that there are positive aspects to a wandering mind.

|
Manipulating Memory
Armed with a better understanding of memory, neuroscience offers hope of noninvasive treatment for a host of psychiatric problems.

|
The Structure And Function Of Neurons
Movement and activity depend upon the coordination of many cells. The nervous system is what produces this coordination and messages are passed to the brain for response

Why Do People Get Ice Cream Headaches?
Ice cream headaches occur when people eat cold food or drinks such as ice cream or "Slurpees", which can cause stabbing pain in the temples and frontal lobe of the brain.

How Humans' Taste Buds Work
Taste buds are located on the tongue, palate and throat and provide sense of taste. The nerves in the tongue send signals to the brain to interpret flavors.
|
|
How Do Humans Hear?
Sound waves entering the ear canal induce pressure waves that activate a series of events involving membranes, miniature bones, and specialized hairs.
|
|
What Is the Pupil and How Does It Change Size?
Nerve responses and specialized structures control the aperture that regulates the amount of light that enters the eye and falls on the photoreceptors.
|
|
Neural Signal Transduction
Of the three main types of synapses in the brain, glutamatergic synapse formation is the best understood. Thus, scientists can gain an understanding of neural circuitry.

|
How The Human Eye Sees
How the differences in what the left and right eye see, and how the nerves of the eye work to allow humans to distinguish color, 3D and distance.
|
|
Why Do People Need Sleep?
Sleep is crucial for mental and physical health and so people can function properly during their day-to-day activities.
|
|
The Cranial Nerves
The face and senses are served by twelve nerve pairs that run directly into the sensory areas of the brain from the brainstem.
