Medulla
|
hindbrain
breathing, swallowing, blood circulation. automatic responses |
|
cerebellum
|
hindbrain
coordination of voluntary movement |
|
Midbrain
|
includes RAS
|
|
RAS
|
reticular activating system which is responsible for selective attention and arousal
|
|
Hypothalamus
|
Homeostasis, expression of rage and fear. release of hormones. suprachiasmatic nucleus is contained in the hypothalamus and it regulates circadian rhythms.
|
|
Suprachiasmatic Nucleus
|
in the hypothalamus. regulated circadian rhythms
|
|
Thalamus
|
relay station for all senses except olfactory
|
|
Basal Ganglia
|
voluntary motor movement
|
|
Limbic system
|
is the emotional brain and contains the amygdala and hippcampus
|
|
amygdala
|
part of the limbic system. emotional reactivity, attaches emotion to memory
|
|
hippocampus
|
part of limbic system.memory consolidation
|
|
Frontal lobe
|
contains primary motor cortex, prefrontal cortex, broca's area
|
|
Damage to the frontal lobe
|
impaired motor control, deficits in executive functioning, personality and emotional changes, broca's aphasia
|
|
Parietal Lobe
|
contains the somatossensory cortex
|
|
damage to the parietal lobe
|
contralateral neglect, apraxia, tactile agnosia, asomatognosia, anosognsia, gerstmann's syndrome
|
|
Temporal lobe
|
contains the auditory cortex, wernicke's area
|
|
damage to the temporal lobe
|
disturbances in auditory sensation and perception, memory deficits, wernicke's aphasia
|
|
Occipital Lobe
|
visual cortex
|
|
damage to the occipital lobe
|
disturbances in visual sensation, perception, and memory (visual agnosia, cortical blindness)
|
|
Left hemisphere functions
|
written and spoken language
verbal memory logical, rational thought, positive emotions |
|
Right hemisphere functions
|
visual spatial skills, creative intuitive thought, nonverbal memory, negative emotions
|
|
how memory is stored
|
amydala attaches emotion to memory, hippocampus consolidates info to long term memory, temporal lobe stores long term memories
|
|
Memory and the Prefrontal Cortex
|
damage to the prefrontal cortex on memory has two effects:
1. impaired ability to remember sequences of things (order) 2. ability to reduce proactive interference |
|
James-Lange Theory
|
emotions are perceptions of body reactions to events
"I must be scared, I am shaking" |
|
Schachter-Singer Two Factor Theory
|
Emotions are the result of a combination of physio arousal and cognitive interpretation (epinephrine study)
|
|
Cannon-Bard Theory
|
emtions occur when thalamus stimulates the pns and the cortex after receiving sensory info
|
|
Long Term Potentiation is
|
High stimulus alters the structure of synapses. underlies long term memory.
|
|
RNA and memory
|
protein synthesis is important for long term memory formation
|
|
Post-Concussional Disorder involves
|
loss of consciousness, amnesia, seizures
2. deficits in attention or memory 3. three or more symptoms for at least three months (irritability, fatigue, depression) |
|
Symptoms of Hypothyroidism
|
bradycardia, cold intolerance, confusion, impaired attention and memory, depression, fatigue
|
|
Symptoms of Hyperthyroidism
|
tachycardia, heat intolerance, decreased attention span, restlessness, emotional lability, mania, insomnia
