Test corrections orange/blue/green Flashcards
when photoreceptors and bipolar cells are stimulated what happens
they vary their voltage
what do retinol ganglion cells vary
spike rate
what do retinol ganglion cells cross through
optic chiasm
what do retinol ganglion cells ascend to
dorsal geniculate nucelus on opposite side of the brain
simple cells responds best to
stationary line in correct orientation - have inhibitory and excitatory areas
where does the ventral stream do down to
inferior temporal lobe
where does the dorsal stream go up to
posterior parietal lobe
what do lesions to the parietal lobe cause
optic ataxia
what is optic ataxia
deficits in visually guided reaching but intact visual function
where is the samatosensory cortex
in the parietal lobe just before the central sulci
what is hemispatial neglect
impaired field contralateral to brain lesion, but no damage to visual system
people in the stroop task with damage to their frontal lobe
cannot ignore word, say this instead of colour
base pairings
A-T G-C
what is tuners syndrome
XO karyotype, short, infertile, low IQ - under developed ovaries
neuronal circuit involved in producing facial expressions
corticospinal system + pyramidal tract
James-lange theory of emotion
physiological response comes first before emotion
criticised people with spinal cord injury still feel emotion
Cannon-bard theory of emotion critisism
feel emotions, then physiological response
force smile = feelings of happiness
what emotion is the amygdala involved in
fear
what does the hippocampus project to via the fornix
hypothalamus
hypothalamus function
link endocrine system to nervous system via the pituitary gland
lesions to the ventromedial prefrontal cortex ….
performed badly on lowa gambling task
what is the best way to understand behaviour
understand its useful functions to an organism
sleep deprived humans
sleep longer for a few nights
what does the stimulation of the reticular formation do in sleeping cats
cause them to wake up
where does the mesolimbic pathway start
ventral tegmental area
where does the mesolimbic pathway end
nucelus accumbens and amugdala
what is the mesolimbic pathway
dopaminergic reward pathway connects midbrain to nucleus accumbens
what is nucleus accumbens function
central role in reward circuit
what is amphetamine to dopamine
stimulant, dopamine agonist
what does dopamine do to Sz
induces positive symptoms of Sz
what is the seasonality effect
increase in Sz born late winter early spring
