Cog. Neuro Flashcards
(29 cards)
released at the synapse
neurotransmitters
proposed neuron doctrine
Cajal
limitation to nerve net theory
technology limitation
firing of specialized neuron that responds to a specific object
specificity coding
MRI long version
magnetic resonance imaging
MRI does what
determines structure of brain
these neurons only respond to specific stimuli
feature detector
principle that says we don’t have direct contact with stimuli, but instead our brain creates reps of the world
principle of neural representation
patient damages one area causing a to be messed up but B to be ok.
double dissociation
define neuron doctrine
individual neurons transmit signals… they are not continuous with others… there’s a gap
small gap between a neuron’s axon terminal and the dendrite
synapse
charge when there’s no signal being transmitted
-70 millivolts
action potential
nerve impulse sent down axon
stimuli to cats causes specific neuron to fire
hubel and wiesel
charles gross found what
monkey simple/complex stimuli
neurons in temporal lobe respond to what?
complex stimuli
neurons in visual cortex respond to what
simple stimuli
sensory coding
how neurons represent various characteristics of the environment
populatio coding
a large number of neurons to rep a particular object
sparse coding
small number fired/object
cerebral cortex
cognitive function
occiptal lobe
vision
temporal lobe
hearing
parietal
sensory
