the explanation of color vision based on the coding of 3 primary colors (red, green, and blue) is called

trichromatic theory

what allow sensory systems to interact

receptive fields

what is the experience of sensation

perception

the ventral stream is considered the “what stream” & the dorsal stream is considered the ____ pathway

how

just before entering the brain, the optic nerves in each eye partly cross, forming the 

optic chiasm 

what are energy filters that transduce incoming physical energy into neural activity 

receptor neruons

neural coding of location begins in the ___ and is maintained throughout all visual pathways

retina

the ____ sends info to a disproportionately large part of the occipital cortex 

fovea 

each retinal ganglion cell responds only to the pretense of absence of

light

the amount of light an object reflects relative to its surroundings is called

luminance contrast

damage to the FFA can result in

facial agnosia

blindness of the entire left or right visual field is called

homonymous hemianopia

what is a deficit in the visual control of reaching and other movements

optic ataxia

what are the 3 physical properties of sound waves 

• strength

• flexibility 

• pressure 

the number of cycles a wave completes in a given time is called

frequency

the receptor surface in the cochlea that transduces sound waves into neural activities is called the

basilar membrane

what are the 3 bones in the human ear

• hammer 

• stirrup

• anvil 

hair cells in the ____ code frequency as a function o their location on the basil membrane

cochlea

people who suffer from ___ can speak fluently, but their language is confused and makes little sense

wernickes aphasia 

in ITD, the computation of left-ear/right-ear arrival times is carried out in the 

medial part of the superior olivary complex

____ area matches speech sounds to the motor programs necessary to articulate them

brocas

song development in young birds is influenced not just by genes by also by

learning

in many bird species, the control of song in the brain is lateralized to the

left

the cerebellum contributes to motor control by improving movement

timing

the ___ organize(s) movement sequences

premotor cortex

the main efferent pathways from the motor cortex to the brainstem to the spinal cord are the

corticospinal tracts

_____ theory states that the motor cortex has a map of where body parts can be in space

position point

a movement module programmed by the brain and produced as a unit is called a

motor sequence

corticospinal-tract fibers that cross to the opposite side of the spinal cord form the ___ tracts

lateral

the ___ contribute(s) to motor control by adjusting the force associated with each movement 

basal ganglia 

the part of the thalamus that carries info about body senses to the somatosensory cortex is called the 

ventrolateral spinothalamic tract 

____ is the perception of pain, temperature, or itch

nociception

damage to the secondary somatosensory cortex (SII) produces _____, an inability to complete a series of movements 

apraxia
