localization of functions Flashcards
What is localization of functions?
The theory that specific parts of the brain correspond to specific behaviors
what is strict localization?
1 brain part corresponds to 1 behavior
what is relative localization?
many parts can correspond to 1 behavior or 1 brain part to many behaviors
what is the frontal lobe responsible for?
executive functions-planning, decision making and speech
what is the occipital lobe responsible for?
visual processing
what is the parietal lobe responsible for?
perception of stimuli
what are the 5 parts of the limbic system?
amygdala
basal ganglia
hippocampus
hypothalamus
nudei accumbens
what is the temporal lobe responsible for?
auditory processing and memory
what is the amygdala responsible for?
plays a role in the formation of emotional memories and fear responses
what is the basal ganglia responsible for?
plays a role in habit forming and procedural memory
what is the hippocamus responsible for?
responsible for the transfer of short-term memory to long-term memory
what is the hypothalamus responsible for?
involved in homoeostasis, thirst, hunger cue, control of autonomic nervous system
what is the nuclei accumbens responsible for?
plays a role in addiction and pleasure
what are the 3 types of memory?
semantic memory
episodic memory
procedural memory
what is semantic memory?
the “encyclopedia” of the brain, general knowledge
what is episodic memory?
autobiographical memories
what is procedural memory?
“how to don things”, habits
what are 2 studies that supports localization of function?
the case study of HM by Milner
the quasi of sharot
Milner used method triangulation, what are some methods she used?
IQ tests
observations of HM
interviews with HM and HM’s family
tasks 9 (reverse mirror drawing)
what 2 types of amnesia did HM have?
partial retrograde amnesia (remembered some past information)
anterograde amnesia (unable to consolidate memory)
what are 2 strengths of HM?
method triangulation was used, increased credibility
longitudinal= can observe changes over time
what are 2 limitations of HM?
informed consent, brain damage patient cant give consent
researcher bias, connection with patient
what is the aim of Sharot?
to investigate the biological component of emotional memories (flashbulb memories)
what are some strengths of Sharot
FMRI= reliable
what are some limitations of Sharot?
quasi= no cause and affect
brain can be activated for many reasons
small sample size-low generalizability
American= cultural bias
