Hint	Answer	% Correct
Cognitive neuroscience is the study of the ___ basis of cognition	physiological	31%
Neurotransmitter: when action potentials reach the ___ at the end of the axon, a chemical called a neurotransmitter is released, which transmits the signal across the synapse to another neuron	synapse	31%

Double dissociation: occurs if damage to one area of the brain causes function A to be ___ while function B is ___, and damage to another area causes function B to be ___ while function A is ___	absent, present, absent, present	6%
Neural circuits: neurons are not conneced ___ but form connections only to ___ neurons --> groups of ___ neurons, which together form neural circuits	arbitrarily, specific, interconnected	6%
Occipital lobe: at the ___ of the head, ___ cortex which receives signals from our ___ is in the temporal lobe	back, visual, eyes	6%
Synaptic transmission is ___ and not ___, this is the moment at which signals can be ___ and ___	biochemical, electric, changed, managed	6%
Extrastriate body area (EBA): activated by pictures of (parts of) ___, but not by ___	bodies, faces	6%
Dendrites: ___ out ___ the cell body to ___ signals from other neurons	branch, from, receive	6%
Distributed representation: the idea that specific ___ functions activate ___ areas of the brain (there is more to a face than just recognizing it)	cognitive, many	6%
Neurons in the temporal lobe respond to ___ geometrical stimuli	complex	6%
Principle of neural representation: everything a person ___ is based not on ___ contact with stimuli, but on ___ in the person's nervous system	experiences, direct, representation	6%
___ and ___ of action potentials are consistent, but ___ rate can change (how close nerve impulses are together) --> the magnitude of experiences is related to the firing rate	height, shape, firing	6%
Action Potential: when nerve ___ is transmitted down the ___, the charge inside the ___ rises to +40mV, then charge reverses course and becomes negative again, lasts for 1 millisecond, travels all the way down the axon without changing ___/___	impulse, axon, axon, height, shape	6%
Neuron doctrine is the idea that ___ cells transmit ___ in the nervous system and that these cells are ___ with other cells	individual, signals, not continuous	6%

Neurons in the visual cortex respond to ___ stimuli like ___	simple, bars	6%
Receptors: neurons that are ___ to pick up information from the ___	specialized, environment	6%
Representation by single neurons in the visual system (CS): presented visual stimuli to cats to see which ___ cause a specific ___ to fire, each ___ in the visual area of the cortex responded to a ___ type of stimulation presented to a small area of the retina --> feature detectors	stimuli, neuron, neuron, specific	6%
Neurons in another area of the ___ lobe respond to ___ shapes or ___	temporal, hand, faces	6%
Feature detectors are in the ___ cortex, a tree for example is represented by the ___ respones of many feature detectors	visual, combined	6%
Hierarchical processing: neurons in the ___ cortex send their axons to ___ levels of the visual system, where signals from many neurons ___ and ___. These then send signals to even higher areas, etc.	visual, higher, combine, interact	6%
Representation by neurons (CS): recorded ___ from individual ___ in a monkey's temporal lobe while a variety of different ___ were presented on a screen, those neurons reacted to ___ stimuli	activity, neurons, stimuli, complex	0%
Temporal lobe: ___ cortex which receives signals from the ___ and is responsible for ___, areas in the ___ temporal lobe are associated with the processing of ___ visual information	auditory, ears, hearing, lower, complex	0%
fMRI (function magnetic resonance imaging): takes advantage of the fact that blood flow ___ in areas of the brain ___ by a cognitive task, haemoglobin molecules carries oxygen, which has ___ properties. Haemoglobin molecules lose some of the oxygen in areas of ___ brain activity --> makes haemoglobin more magnetic. Thus, the fMRI apparatus determines the ___ activity of various areas of the brain by detecting changes in the ___ response of the haemoglobin	increases, activated, magnetic, high, relative, magnetic	0%
Parahippocampal place area (PPA): activated by perceiving pictures representing ___ and ___ scenes	indoor, outdoor	0%
Frontal lobe: receives signals from all of the ___ and is responsible for ___ of the senses, higher cognitive functions like ___ and problem ___	senses, coordination, thinking, solving	0%
