Experimental Research

variables
causality possible
bias affects

Neurons

receive, integrate, transmit info

Dendrites

receive info

Axons

send info

Sensory Neuron

relay info to brain

Efferent signals

to muscle fibers

Afferent Signals

to spinal cord

Glial Cells

produce myelin
schwann & oligodendrocytes

Schwann Cells

produce myelin for PNS

Oligodendrocytes

produce myelin for CNS

At resting potential, what cell is predominately inside the cell? outside?

inside-- K+
outside-- Na+

Hyperpolarized

negative charge
less likely to fire

Depolarized

positive charge
more likely to fire

Sodium-Potassium Pump

3 Na+ out
2 K+ in

Presynaptic Neurons

synthesize and release molecules

Postsynaptic neurons

bind to specialized receptors

Acetylcholine

learning
memory

brain
spinal cord

PNS

sense organs
ANS
Somatic

ANS

self regulated actions

Sympathetic Response

emergency system
increase heart rate

Parasympathetic Response

return to normal

Forebrain

higher level thinking
cotex, basal ganglia, limbic system, thalamus, hypothalamus

Midbrain

simple movements

Hindbrain

reflexes
respiratory functions

heart rate
respiration

Cerebellum

smooth movements
balance

Pons

motor control
REM sleep

Reticular formation

heart rate
wakefullness

Thalamus

receives almost all info
relays to cortex

Hypothalamus

regulates vital functions

Amygdala

Postcentral gyrus

somatic (body) sensations

Bottom-up

affected by experience

Top-down

no prior knowledge

Photoreceptors

capture light
cones
rods

Cones

colors
s- BLUE
m- GREEN
l-RED

Rods

darkness

Horizontal/Amacrine cells

lateral projections

Bipolar cells

transfer info from photoreceptors to ganglion cells

Ganglion cells

communicate info to thalamus
form optic nerve
fire action potential

Ventral processing

WHAT you are seeing

Dorsal processing

WHERE it is

Gestalt perception

whole is greater than sum of parts

Monocular

occlusion, relative size, linear perspective, texture gradient, position to horizon, motion parallax

Encoding

first encounter

Retrieval

access info and use it

Characteristics of Memory

duration
capacity
effects of encoding

Measuring Memory (3 R's)

recall
recognition
relearning

Sensory Memory

information lost
held for VERY SHORT period of time

Proactive Interference

old info prevents new info

Retroactive Interference

new info prevents old

Factors that Affect LTM

depth of processing
state dependent learning
context dependent learning
