biopsych Flashcards
two nervous subsystems
central
peripheral
the CNS is made up of
the brain and spinal cord
the peripheral nervous system has
autonomic nervous system
somatic nervous system
what side of the brain is the language system
left side
what area is responsible for speech production
brocas
what area is responsible for language understanding
wernickes
Sperry
split brain research
define synaptic transmission
electrical impulses reaches end of pre-synaptic terminal
tiggers release of neurotransmitters
from synaptic vesicles
taken up by post-synaptic receptor sites on dendrites
what is an inhibitory neurotransmitter
makes a neuron less likely to fire - serotonin
what is localisation
specific areas of the brain have specific purpose
what is hemispheric lateralisation
left and right of the brain act separately
what’s plasticity
brain had ability to change throughout life
what is functional recovery
after trauma unaffected areas of the brain cap adapt and compensate for damaged areas
Maguire 2000
London taxi drivers had a larger posterior hippocampus than a matched control group demonstrates plasticity
how does fMRI work
detecting blood flow and oxygenation that occur with activity
