additional final Flashcards
Spinocerebellar tracts
spinal cord m– to cerebellum, going from down to up
what effect does free vs encapsulated nerve endings have on somatosensory receptors?
encapsulated = increases its sensitivity
sensation is unconcious
binding problem of perception
The binding problem considers that features of an object need to be bound together by some neuronal mechanism across a population of neurons, so that the object can be perceived as a whole.
sensory neuron vs specialized receptor
sensory neuron: takes info into the CNS; sensory receptor can’t do this
“homunculus’ meaning
little man
effect of wave length on energy
long wavelength: lower energy
shorter wavelength: higher energy
cones and their pigments
each cone can respond to more than one color, but they are most sensitive to the specific color
does the fovea havbe any rods
no
do p and m cells go to geniculostriate?
all p cells go here and most m cells
remaining m cells go to tectopulvinar
at what decibal does hearing damage occur?
15 mins of 100 db can cause permanent hearing damage/death of inner hair cells
function of outer hair cells
alter the stiffness of the tectorial membrane to dampen or amplify sounds
where is the subthalamic nuclei located?
in diencephalon
where is the substantia nigra located?
midbrain
ASD and cerebellum social functions
shows that cerebellum has higher social functions; in kids with autism, cerebellum has decreased purkinje neurons: IT SOCIALLY ERROR CORRECTS AS WELL BUT DOESN’T DO THIS IN ASD
