biopsychology Flashcards
what nervous system deals with voluntary movement and external stimuli
somatic nervous system
what nervous system deals with the internal bodily organs
autonomic nervous system
what is triggered by the sympathetic nervous system during stress
fight / flight
what system would restore the body to resting levels after stress
parasympathetic
what part of a neuron receives the signal from a previous neuron
dendrites
what part of neuron carries the signal away from the cell body
axon
what is the name for the gap between two neurons
synapse
what type of neurotransmitter would actually prevent the signal being passed on
inhibitory
what is the master glad of the body that controls the production of other hormones in the body
pituatary gland
what type of neuron carries a signal away from the CNS to the muscles of the body
motor
the theory that different functions are controlled by specific areas of the brain
localisation of function
what lobe would you find the visual cortex in
occipital
what lobe would you find the motor cortex in
frontal
what area of the brain controls speech production
brocas
what area of the brain controls language comprehension
wernick’s
what is the name for the brains ability to reorganize and repair itself by forming new neural connections throughout life
plasticity
the idea that certain functions are controlled by either hemisphere of the brain
lateralisation
the name of the researcher that studied split brain patients
Sperry
a brain scanning method that tracks generalised electrical activity in the brain
EEG
a method of investigating the brain of people after death
post mortem
a scanning method which attempts to pin point specific electrical activity in response to stimuli
ERP
the name for whether there is a lag time between the brain’s activity and it showing on a scan image
temporal resolution
what happens as the brain develops - the reducing of unused neurons in the brain and strengthening of used one
synaptic punning
in plasticity the name for the growth of new neurons in the brain
axon sprouting
