Psych

Front 1

Tiny electrical charge that occurs when positive sodium ions rush into channels located in gaps between myelin sheaths

Back 1

Action potential

Front 2

A series of separate action potentials that occur segment by segment as they move down the axon

Back 2

Nerve impulse

Front 3

If ap starts at the beginning of an axon it will continue at the same speed to the very end

Back 3

Action potentials follow the all or none law

Front 4

thin layer of cells that covers nearly the entire surface of the forebrain where the vast majority of neurons are located

Back 4

Cortex

Front 5

Fatal condition of being born with little or no brain

Back 5

anencephaly

Front 6

gyri & sucli

Back 6

wrinkles

Front 7

Involved in many different functions voluntary motor movement personality emotions normal behavior and many more

Back 7

Frontal lobe

Front 8

Functions include hearing speaking coherently and understanding verbal and written information

Back 8

Temporal lobe

Front 9

Primary function is processing visual information example being hit in the back of the head seeing stars

Back 9

occipital lobe

Front 10

relatively meaningless bit of information that result when the brain processes electrical signals that come from sense organs

Back 10

Sensation

Front 11

When a sense organ changes physical energy into signals that can be sent to the brain

Back 11

transduction

Front 12

A decreasing response sense organs have to a continuous stimulus

Back 12

adaptation

Front 13

One particular segment of electromagnetic energy that we can see because these waves are the right length to stimulate receptors in our eyes

Back 13

Visual spectrum

Front 14

Send impulses from back of eye to a pit stop in the thalamus for initial processing

Back 14

Optic nerve

Front 15

Transforms impulses into simple visual sensations and send those out to visual association areas to form complex meaningful images

Back 15

Primary visual cortex

Front 16

Interdisciplinary field of scientific study that examines the structure and function of all parts of the nervous system including the brain spinal cord and network of brain cells

Back 16

Neuroscience

Front 17

Internal timing devices that are genetically set to regulate various physiological responses for different times

Back 17

biological clocks

Front 18

refers to a biological clock which regulates physiological responses within an approx. 24-hour time period

Back 18

circadian rhythm
