26
parietal lobe functions
reception and evaluation of sensory touch
27
Occipital lobe functions
reception and integration of visual input
28
Temporal lobe functions
reception and evaluation for smell and hearing
29
Broca's area
frontal lobe- initiates muscle movements necessary for speech
30
wernicke's area
temporal lobe- auditory or visual comprehension of language
31
what makes up the brain stem?
Medulla oblongata, pons, midbrain, reticular formation
32
Pons functions
controls respiratory rate and function
33
midbrain controls
reflexes
34
where is the post central gyrus located?
parietal lobe
35
where is the limbic sister located?
part of cerebrum and diencephalon
36
what does the limbic system control?
appetites- food and sex | emotions- desires, rage, jealousy, aggression, memory, reproduction, survival
37
when is out limbic system fully developed
25 yo
38
the limbic system is
the natural man
39
4 factors of the addictiveness of a substance
1. highly stimulating version of a natural product 2. available in limitless supply 3. comes in lots of varieties 4. may cause a binge without realizing it is triggering brain changes
40
three stages of memory?
working, short-term, long-term
41
how long does working memory last?
seconds
42
how long does short term memory last?
minutes to days
43
What are the two types of long term memory?
Declarative (explicit) and procedural(implicit)
44
explicit memory involves
test questions, address
45
implicit memory involves
playing the piano
46
where does working memory most occur?
frontal cortex
47
where does short term memory occur?
temporal lobe: hippocampus- factual content amygdala- emotional overtones
48
consolidation
occurs in long term memory | more and stronger sysanpses-> produce dendritic spine
49
Memory engram
series of neurons and their patter of activity
50

can't make new memories after neurological insult
51
why can't you remember what happens after and accident?
anterograde amnesia
