Answer 10

neural fibers that connect the 2 hemispheres of the brain

Question 11

plasticity

Answer 11

refers to the brain’s ability to change and reorganize

Question 12

EEG

Answer 12

(electricity) records brain waves f electrical activity via electrodes on scalp

Question 13

PET

Answer 13

(radioactive glucose) visual display that shows where glucose goes in brain

Question 14

CT

Answer 14

(radioactive) advanced x ray - takes many angles of images to show structure

Question 15

MRI

Answer 15

(magnetic field) creates computer generated images of brain anatomy - more detailed than CT

Question 16

fMRI

Answer 16

(blood flow) measures brain activity and blood flow to show structure and function

Question 17

Brainstem

Answer 17

central core of the brain - made up of pons and medulla

Question 18

medulla

Answer 18

base of brainstem - controls heartbeat and breathing

Question 19

pons

Answer 19

above medulla - controls sleep and coordinates movements

Question 20

reticular formation

Answer 20

nerve network that goes through brainstem into thalamus - controls arousal nd filters sensory stimuli

Question 21

cerebellum

Answer 21

rear of the brainstem - processing sensory input, coordination, balance, nonverbal learning/memory

Question 22

limbic system

Answer 22

hypothalamus, amygdala, hippocampus

Question 23

hypothalamus

Answer 23

below thalamus - directs eating, drinking, body temp - helps govern endocrine system via pituitary gland

Question 24

amygdala

Answer 24

2 lima bean neural clusters - linked to emotion, fear, and aggression

Question 25

hippocampus

Answer 25

wraps around thalamus - helps process conscious memories of facts or events for storage

Question 26

left hemisphere

Answer 26

speech, language, controls right side of body, math calculations

Question 27

right hemisphere

Answer 27

inferences, visual perception, controls left side of body, emotion recognition

Question 28

parasympathetic nervous system

Answer 28

calms you, speeds up digestion and heart rate

Question 29

When there is a negative charge inside an axon and a positive charge outside of it, the neuron is

Answer 29

said to have a resting potential

Nerve cells in the brain receive life-supporting nutrients and insulating myelin from

Answer 30

glial cells

Question 31

sympathetic nervous system

Answer 31

arouses body and increases heart rate and breathing - part of autonomic nervous system

Question 32

Peripheral nervous system

Answer 32

contains both the somatic and autonomic nervous systems

Question 33

dual processing

Answer 33

info processed on seperate conscious and unconscious tracks (2 track mind)
