25 Cards in this Set

  • Front
  • Back
parts of a neuron
Dendrite
Soma (cell body)
Axon
Terminal
Synapse
glia
support cells of the NS
Brainstem
medulla
pons
midbrain
cranial nerves
midbrain
Inferior and superior colliculi, important for orienting to auditory and visual stimuli, integration
medulla
Breathing, blood pressure, heart rate
pons
Arousal, breathing, relay center
cranial nerves
Sensory & motor information for the head
cerebellum
Important for motor movements, balance, coordination

Growing evidence suggests a role in many cognitive functions (attention, learning, language)
diencephalon
thalamus
hypothalamus
pineal gland
pituitary gland
thalamus
Relay center of the brain
Almost all incoming sensory and outgoing motor info is initially processed here
hypothalamus
Regulation of body states via interaction with the endocrine system
Hunger, thirst, sex drive, temperature, sleep/wake
pineal gland
Melatonin: circadian rhythms
pituitary gland
Hormone secretion: growth, water regulation, metabolism, reproductive function
5 lobes of cerebral cortex
occipital lobe
temporal lobe
frontal lobe
parietal lobe
limbic lobe
occipital lobe
primary visual cortex, visual association areas
temporal lobe
Primary auditory cortex, auditory association areas

Visual association areas, multisensory integration
frontal lobe
Primary motor cortex, supplementary motor areas

Prefrontal cortex - higher order cognitive processes

Abstract thinking
Judgment
Planning
Decision-making
Attention
Inhibition
Working memory
Personality
parietal lobe
Primary somatosensory cortex, association areas

Attention, sensory integration
limbic lobe
1) Cingulate gyrus
Conflict resolution, Prefrontal
cortex interface

2) Hippocampus
Memory consolidation,
spatial learning

3) Amygdala
Emotional learning, fear,
memory modulation
basal ganglia
Motor control and reward learning

Consist of 4 regions:

Subthalamic nucleus

Globus Pallidus

Substantia nigra

Striatum
-Caudate
-Putamen
VTA projections
Ventral striatum (Nucleus Accumbens) – Reward, “wanting”

Olfactory bulb - Sensory

Amygdala – emotional memory

Hippocampus - memory

Orbital and medial prefrontal cortex – Value, cognitive control of behavior

Cingulate cortex – mediates aspects of all above
SNc projections
Dorsal Striatum – learning and executing motor programs
Raphe nucleus
cell bodies for serotonin here
raphe projections
Caudal-medulla and spinal cord

Dorsal and median -rest of CNS, VERY diffuse
serotonin influences:
Sleep
Arousal
Attention
Processing of sensory info
Aspects of emotion and mood (including aggression)
