speech and sleep Flashcards
wernicke area
sensory speech
understanding what is heard
broca area
motor speech
sends messages to appropriate muscles to make sound work
wernicke and brocra area connected by
arculate fasiculus
right side of brain controls
muscle activity and receives info from left side of body
spatial perception, recognition of faces, musical ability
left side of brain controls
muscle activity in and receives info from right side of body
mathematics and speech
corpus callosum

EEG
recording of brains electrical activity
alpha
resting state with eyes closed
beta

sleep is a cyclic pattern between ___ and ___
NREM and REM
working memory
task associated memory
brain briefly stores info for a task
ie a phone number
short term memory
info retained for minutes to days
involved long term potentiation
long term potentiation
strengthening of synapes
facilitation of future APs by increase in number of NT glutatmate on presnyaptic side or increase in number of receptors on post synaptic side
long term memory
retention for days to years
involved consolidation
declarative memory
retention of facts
hippocampus and amygdala
procedural memory
development of skills ie riding a bike
cerebellum and premotor area
consolidation
process of forming stronger synapses over a period of years
memory engram
series of neurons and their activity
involved in long term retention of information
repetition and association helps turn short term into long term
limbic system
influences emotions, motivation, food sensation of pain and pleasure
basic survival instincts
hippocampus association with limibic system important for
satiation and survival
