Psychology Unit 2: Part 1 - Biological Bases of Behavior

receive messages form other cells

passes messages away from the cell body to other neurons, muscles, or glands

a signaling molecule secreted by a neuron to affect another cell across a synapse

the junction between two neurons or between a neuron and a muscle

covers the axon of some neurons and helps speed neural impulses

electrical signal traveling down the axon

Serotonin, Dopamine, Acetylcholine, Endorphins

affects mood, hunger, sleep, and arousal

influences movement, learning, attention, and emotion

enables muscle action, learning, and memory

Insert an electrode into a part of the brain and record neural firing

Measure overall brain electrical activity (measured in waves)

X-ray of the brain

Uses magnetic technology to get a picture of the brain’s soft tissue

Uses magnetic technology and measures blood flow to active areas

Insert glucose into the patient, glucose goes to active areas of the brain (the brighter the color, the more neural activity)

Using electrodes, magnets, or chemicals, you induce firing in a certain part of the brain

Cutting or burning of neural connections

the thin layer on the top of your brain

Speech, muscle movement, planning, personality

Primarily movement and sensations

Primarily auditory

Primarily sight

Someone with damage to this area will not be able to speak

Someone with damage will not be able to understand/comprehend speech

hemispheres

a large bundle of nerve fibers that connect the two brain hemispheres, permitting communication between the right and left sides of the brain

logic, problem-solving, math, language, etc.

emotions, art, music, creativity, facial recognition

the brains ability to change and take over functions of damaged parts

he survived a traumatic brain injury caused by an iron rod that shot through his skull and obliterated the greater part of his left frontal lobe
