Nature vs Nurture

Is it how we are born or raised that affects our behavior

A little bit of both

1

Synapse

Gap between two separate dendrites

2

Myelin Sheath

covers axon of some neurons and helps spread neuron impulses

3

Axon

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

4

All or Nothing Principle

When neuron reaches certain charge it will all go, no take backs

5

Resting Potential

Neuron set/ready to fire, can generate action potential

-70

6

Refractory Period

Neuron cannot die Adair for a short amount of time

7

Endorphins

Pain killers for body

8

Acetylcholine

Muscle contractions, learning, memory

9

Dopamine

Movement, attention, learning, pleasure and reward

10

Somatic vs Automatic

Somatic - voluntary control of skeletal muscles

Automatic - controls glands and muscles of our internal organs

11

Sympathetic vs. parasympathetic

Sympathetic - arouses and expends energy

Parasympathetic - calms and stores energy

12

Left vs Right Hemisphere

Left -
Logic and language

Right hemispheres
Creativity and special

13

Frontal lobe

Speaking p, muscle movements, and in making plans/judgements

14

Parietal Lobe

Sensory input for touch/body position

15

Occipital lobe

Info from vision

16

Temporal lobe

Receives info from opposite ear

17

Reticular Formation

Nerve network in brain, play role in arousal

18

Hypothalamus

Maintains homeostasis, controls endocrine system, rewards too, creates fight/flight mode

Lateral - hungry
Ventromedial - fullness

19

Cerebellum

Movement output and balance, rear of brain

20

Medulla

Base of brain steam, controls heartbeat/breathing

21

Broca vs Wernicke's Area

Broca's area - allows movement of mouth for speech, just talking not singing though

Wernicke's Area - damage here prevents cohesive speech, audio cues received processed here

22

Pineal Gland

Releases melatonin, controls sleep patterns

23

Pancreas

Regulates level of blood sugar in blood

24

Pituitary

Listens to hypothalamus and controls growth and controls other endocrine systems (secretes many hormones)

25

EEG

Read out of electrical brain waves

26

PET

Shows where brain consumes glucose

27

MRI

Disorienting brain atoms to use signal of the, returning to place to create an image

28

Split brain research

We're able to study different hemispheres by portraying images to separate sides of vision

Can do this surgery to lower amount of seizures
