100
Q

Functional class of neurons

  • sensory = PNS -> CNS
  • interneuron
101
Q

Structural class of neurons

A
  • multi polar neuron
  • bipolar neuron
  • unipolar
102
Q

Multipolar neuron

A
  • most common
  • can carry sensory and motor info
  • can cause muscles to contraction
  • 1 axon with multiple different dendrites
103
Q

Bipolar neurons

A
  • rare
  • found with sensory perception in the eye and ear
  • in retina
  • 1 axon and 1 dendrite
  • close to surface
  • pass in one direction
104
Q

unipolar neurons

A
  • one action
  • small section of dendrites
  • most of body sensory neurons
  • 1 process from cell body
  • whole thing considered axon
105
Q

Resting membrane potential

A
  • -70mV
  • more negative inside cell
  • three sodium ions leave the cell and 2 potassium ions enter
106
Q

Neurons are polarized

A

at resting state, -70, more negative inside cell

107
Q

How ions separated

A

by phospholipid bilayer, there is more potassium inside the cell and more chloride and sodium outside

108
Q

What pressures act on ions

A
  • diffusion

- electrostatic pressure

109
Q

Gated channels

A

normally closed

  • open in response to specific stimuli
  • ligand gated
  • voltage gated
110
Q

ligand gated channels

A

closed at rest, has binding site, opens when ligand binds with receptor

111
Q

voltage gated channels

A

opens when electrical potential across membrane is altered

112
Q

metabolictropic receptors

A
  • receptor types that take longer to kick in but lasts longer
  • work by activating G protein/second messengers
  • either alter the opening of G protein gated ion channel for stimulating affecter enzyme they either synthesizes or breaks down a second messenger
113
Q

ionotropic receptors

A

different types allow different flow, ligand gated, faster but don’t last as long

114
Q

how ap initiated

A
  • neurons receive chemical messages from dendrites and bind to ligand gated channels -> change in charge
  • if charge is strong enough it produces an ap
  • neuron must become more positive to reach threshold
  • sodium enters cell
115
Q

Spatial summation

A

NT linger, charge builds up, see repeated messages

116
Q

temporal summation

A

enough positive charge to create negative -55mV -> fire

117
Q

hyperpolarization

A

more IPSP then EPSP

- decreases membrane potential further away from threshold charges further apart

118
Q

depolarization

A

increases membrane potential toward neutrality and approach threshold
- more EPSP than IPSP

119
Q

threshold of excitation

A
  • 55mV

- potassium leaves cell by diffusion

120
Q

ions/channels involved in ap generation

A
  • sodium channels and potassium channels

- potassium, chloride, sodium, animo

121
Q

refractory period

A

sodium ions channels close

  • neuron cannot fire right away
  • happens because neuron is too negative and has to reach resting potential
122
Q

myelin

A

insulate the axon and speed up process

123
Q

nodes of ranvier

A

where ap regenerates with ion channels

124
Q

saltatory conduction

A

when the ap skips the nodes of ranvier to next nodes of ranvier

125
Q

parts of synapse

A
  • vesicle = store/carry NT
  • synaptic gap = space in between dendrite and axon term
  • receptor
  • NT
  • presynaptic terminal button
  • post synaptic spine
126
Q

Neuromuscular junction

A

synapse between a neuron and a muscle cell

127
Q

steps of NT

A
  1. synthesis = neurons produce chems for NT
  2. storage/transport - neurons store NT in vesicles, some need to be transported down axon
  3. ap
  4. release = ap triggers release of NT into synaptic cleft
  5. receptor binding = NT cross cleft and attach to receptor on postsynaptic
  6. inactivation = reuptake, diffuse away, inactivated by enzymes
128

  • autonomic
    a. sympathetic
    b. parasympathetic
140
Q

Somatic

A
  • voluntary
  • motor and sensory neurons
  • external environment information
  • goal = voluntary motor control
141
Q

autonomic

A
  • involuntary
  • internal organ/environment
  • smooth/cardiac muscle

    a. sympathetic
    b. parasympathetic
142
Q

sympathetic

A

fight or flight

143
Q

parasympathetic

A

rest and digest

144
Q

gray matter

A

cell bodies, outside, soma with no myelin

145
Q

white matter

A

myelinated axons

146
Q

brain has __ cerebral hemispheres

A

2

147
Q

commissures

A
  • white matter tracks connecting hemispheres

- allow communication between lateralized areas

148
Q

corpus callosum

A
  • largest commissures

- bridge between hemispheres

149
Q

forebrain

A
  • evolutionarily
  • newest
  • voluntary
  • process most comples
150
Q

midbrain

A
  • substantia nigra

- VTA (motivation, reward, addiction)

151
Q

hindbrain

A
  • oldest
  • mid + hind = brainstem
  • perform primitive/life necessary functions
  • priority when starving
152
Q

4 lobes of brain

A
  • frontal
  • parietal
  • occipital
  • temporal
153
Q

Frontal lobe

A
  • motor
  • executive functions
  • personality, decision/plan/perform
154
Q

parietal

A
  • sensory info

- integrate info from senses

155
Q

occipital

A

visual

156
Q

temporal

A

memory/emotion/auditory

157
Q

prefrontal cortex

A
  • control executive function
  • high order mental processes
  • control over some more primitive brain areas to guide behavior
  • last to fully develop @ 20
  • important in addiction
158
Q

Limbic system regions

A
  • amygdala
  • hypothalamus
  • hippocampus
159
Q

amygdala

A

regulate emotion, fear

160
Q

hypothalamus

A

control autonomic NS and endocrine system

161
Q

hippocampus

A

learning, memory, emotions

162
Q

Basal ganglia function

A

motor control, nigrostriatal dopamine pathwat

163
Q

2 major dopaminergic pathways

A
  • nigrostriatal = substantia nigra -> dop -> stiatum

- VTA -> dop -> nucleus accumbens

164
Q

Thalamus

A

process and relay stations, motor info, re-routes info

165
Q

hypothalamus

A

controls autonomic NS and endocrine, controls basic drive, stress response

166
Q

HPA axis

A

hypothalamus -> pituitary -> adrenal glands release cortisol and trigger stress response

167
Q

raphe nuclei

A

make serotonin, mood and sleep

168
Q

locus coeruleus

A

noradrenalin (norepinephrine)

169
Q

hindbrain

A
  • essential for life
  • medulla
  • pons
  • cerebellum
170
Q

medulla

A
  • HR
  • breathing
  • can sense toxins
  • BP
171
Q

pons

A
  • bulb
  • control sleep/wakefulness
  • reticular activating system
172
Q

cerebellum

A
  • little brain
  • lots of cells
  • motor control *fine
  • coordination
  • balance
  • some cognitive
173
Q

phrenology

A

structure of skull determines character and mental capacity

174
Q

lateralization of brain

A
  • L hem = language, receive info/controls R side of body

- R hem = nonverbal info/visual recognition/emotion/perception, receives info/controls L side of body

175
Q

Split brain

A
  • corpus collosum cut

- can see and say what if from R eye but not from L because info can’t cross

176
Q

fMRI

A

can see what area of the brain is most active, detects change in cerebral B flow, functional

177
Q

PET

A
  1. what area of brain have more NT receptor and transporters, injected with radioactively tagged mlc that binds
  2. can measure brain activity, injected with FDG with radiolabeled
178
Q

EEG

A

pick up electro activity from cortex/scalp, senses brain waves, picks up electrical potential, bad for spacial

179
Q

3 levels of analysis in psych

A
  • biological
  • individual
  • social
180
Q

biological analysis

A

memory as brain structure (neuroanatomy)/neurochemical (NT)/gene (hereditory)

181
Q

individual analysis

A

perception, cognition, behavior, individual differences

182
Q

social analysis

A

cultural, interpersonal (groups relationship)
