Brain

parietal lobe

Anatomy; Brain

One of the four major areas of the cerebrum. This area deals with reception of sensory information from the body’s opposite side. It also plays a part in reading, writing, language and calculation.

basal ganglia

Anatomy; Brain

Clusters of nuclei deep within the cerebrum, and the upper parts of the brain stem that play an important part in producing smooth, continuous muscular actions in starting and stopping movements.

thalamus

Anatomy; Brain

Rounded structure in the middle region of the brain that relays sensory signals to the Cerebral Cortex. Only a very small part of the thalamus is in any way related to the limbic structure set.

olfactory bulb

Anatomy; Brain

The olfactory bulb receives and processes smells. It is located very close to the limbic region, which is thought to be the reason that certain smells can activate vivid memories and emotions.

blood-brain barrier

Anatomy; Brain

The blood-brain barrier protects the brain from chemical intrusion from the rest of the body. Blood flowing into the brain is filtered so that many harmful chemicals cannot enter the brain.

limbic system

Anatomy; Brain

A collection of structures that play important roles in emotion, memory, and attention.

dendrites

Anatomy; Brain

These are the strand-like fibers emanating from the neuron. Similar to spider webs or cracks in a wall, they are receptor sites for axons. Each cell usually has many, many dendrites.
