Brain structures
A primitive part of the brain that sits at the juncture point where the brain and spinal cord meet.
What is the Hindbrain?
Groups of neurons that make up neural "transmission cables"
What are nerves?
Cells in the nervous system that receive and transport information.
What are neurons?
What are endorphins?
The use of highly focused beams of X-rays to create detailed photos of the living brain
What is a CT scan?
What is the cerebellum?
The system where muscles are moved, internal organs are regulated, and sensory input is directed toward the brain.
What is the peripheral nervous system?
These cells carry environmental messages toward the spinal cord and brain.
What are sensory neurons?
Has been linked to sleep, general arousal, dreaming, and is linked to psychological disorders
What is serotonin?
A device that monitors the gross electrical activity of the brain

The outer portion of the brain that includes the cerebral cortex and structures of the limbic system.
What is the forebrain?
Collections of nerves that transmit information towards the brain and initiates movement.

Cells that carry information away from the central nervous system.
What are motor neurons?
Fibers that extend outwards from a neuron
What are dendrites?
A device that uses magnetic fields and radio-wave pulses to create detailed 3-D images of the brain
What is an MRI (magnetic resonance imaging)?
Is thought to play a big role in the regulation of various motivational activities, including drinking, and sexual behavior.
What is the hypothalamus?
Consists of the brain and spinal cord and acts as the main part of the body.
What is the central nervous system?
These greatly outnumber neurons
What are glial cells?
The cell body of a neuron
What is a soma?
A method measuring how radioactive substances are absorbed in the brain
What is a PET (positron emission tomography)?
The collection of nerve fibers that connects the two cerebral hemishperes and allows info to pass from one side to the other
What is the corpus callosum?
Groups of nerves that control the autonomic needs of the body.
What is the autonomic system?
Acts as insulation for the axon while also speeding up neural transmission
what is the myelin sheath?
Tiny bulb-like swellings at the end of an axon
What are terminal buttons?
It is used to to map changes in blood oxygen use as a patient thinks or behaves
What is MRI technology?
