nerve impulses travel away from the cell body along this myelin coated extension
Axon
100
Phineas Gage had damage to this part of the brain, which caused a dramatic change to his personality and ability to make sound decisions.
Frontal Lobe
100
researchers can intentionally destroy brain tissue in order to study brain functions by using this technique
Lesioning
100
Part of the nervous system that prepares the human body for the fight or flight response.
Sympathetic
100
responsible for secretion of growth hormones
Pituitary Gland
200
Carries information about muscle movement from the central nervous system to other parts of your body.
Motor Neurons
200
the part of the brain responsible for creating memories
Hippocampus
200
Roger Sperry and Michael Gazzaniga studied how the right and left brain hemispheres were involved in different functions by studying patients who had this part of the brain cut.
Corpus Callosum
200
Part of the nervous system that brings the body to a resting state after running away or staying to fight like a Ninja.
Parasympathetic
200
the area of the brain responsible for speaking/speech
Broca's Area
300
Chemical messengers that aid in the generation of neural impulses
Neurotransmitters
300
this part of the brain is necessary for life functions such as breathing and heart beat.
Medulla
300
this methos of brain study involves injecting radioactive glucose into the patient in order to record brain functioning.
PET Scan
300
The system that consists of glands that produce horomones
Endocrine
300
The hemisphere of the brain responsible for recognizing pictures, faces, shapes and other perceptual information.
Right Hemisphere
400
the gap between neurons where chemical messages are transfered
the synapse (synaptic gap)
400
This nerve network extending through the spinal cord to the brain, is responsible for an organism's level of alertness.
Reticular Formation
400
An EEG (Electroencephalogram) records these.
Brain waves
400
the motor and sensory neurons extending out from the CNS - sends messages to and from the body
Peripheral NS
400
Regulates eating, drinking, body temperature, and the fight or flight reactions to stress. Plays a role in emotions, pleasure, and sexual function
Hypothalamus
500
this describes the neuron as having the ability to "fire" (generate an impulse) or not. There is no partial impulse.
"All or None" response
500
The brain’s sensory switchboard -- directs messages to the sensory receiving areas in the cortex
Thalamus
500
Areas in the Cerebral Cortex that have no known function other than storing information.
Association Areas
500
controls the voluntary movements of the skeletal muscles
Somatic NS
500
This neurotransmitter influences your mood, apetite, sleep, and arousal
