EYES
where are Cones primarily located
Fovea
what is amusia
disorder that appears mainly as a defect in processing pitch
what do phasic cells do?
sensory receptors that are typically inactive but become active for a short time when there is a change in the conditions they are monitoring
Five tastes
Salty • Sour • Sweet • Bitter • Umami
which part of the ear ( not region ) captures and processes sound?
Pinnae
what does the ciliary muscle do
changes the shape of the lens when your eyes focus on a near object
what is Central Deafness
from damage to the cochlear nuclei or the central pathways that relay auditory information to the auditory cortex.
What do Tonic Cells do
adapt slowly to a stimulus and continue to produce action potentials, conveying information about the stimulus's duration
What do Mitral cells do
act as the primary output channel for olfactory information, receiving signals from olfactory sensory neurons and transmitting them to the brain's olfactory cortex,
what happens when the stereocilia sway away.
cation channels open, and the resultant increase in membrane potential of the hair cell causes calcium channels in the base of the hair cell to open, leading to transmitter release.
What cells are ALWAYS excited by light
what is the tympanic membrane?
a thin, semi-transparent membrane that separates the outer ear from the middle ear
what are population codes
Information about quantities in the world is represented by neural activity patterns in a characteristic general fashion
Sweet receptors:
a heterodimer of two G protein-coupled receptors, T1R2 and T1R3
what part of the ear encodes pitch?
basilar membrane
they are excited by glutamate released by the cones.
The utricle and saccule are?
two organs in the inner ear that sense linear acceleration, gravitational forces, and head tilting
What would A-delta fiber be?
Phasic Receptors.
Papillae vs taste buds
papillae are the bumps on the tongue that contain taste buds
What causes the blind spot?
the optic nerve enters the eye, because there are no photoreceptors at that location
where is most glutamate released
in the dark
The cochlear nerve, also known as the acoustic nerve does?
carries auditory information from the inner ear to the brain
Labeled lines are
a mechanism in the nervous system that describes how sensory receptors send signals to the brain
What does the VNO do?
detects specific chemical compounds, including pheromones
what Cortex does the Olfactory cortex transport to.
orbitofrontal cortex (OFC)
