ANSWERS GRADED A+
⩥ receptive field. Answer: an area in visual space from which light
excites or inhibits a cell
⩥ retinal disparity. Answer: the difference between the images projected
onto each retina, which is used by the brain to perceive depth and three-
dimensional space
⩥ stereopsis. Answer: the perception of depth and three-dimensional
space, resulting from the fusion of two slightly different images from
each eye
⩥ dorsal stream. Answer: pathway in the visual cortex is responsible for
visually guided movements; also known as the "where" or "how"
pathway
⩥ fusiform gyrus. Answer: a region of the brain, especially in the right
hemisphere, that specializes in recognizing faces
,⩥ inferior temporal cortex. Answer: brain region involved in recognizing
familiar objects and faces, despite changes in position, size, or angle
⩥ motion blindness. Answer: an impairment in the ability to perceive
movement, despite having normal vision in other regards
⩥ prosopagnosia. Answer: a condition characterized by difficulty in
recognizing faces, often resulting from damage to the fusiform gyrus or
its connections
⩥ ventral stream. Answer: pathway in the visual cortex is responsible for
perceiving objects, also known as the "what" pathway
⩥ middle temporal cortex (MT). Answer: brain region involved in
detecting the direction and speed of moving objects, also known as area
V5
⩥ Amusia. Answer: difficulty perceiving changes in tones or detecting
off-key singing or melodies; commonly known as "tone deafness"
⩥ basilar membrane. Answer: a membrane within the cochlea that varies
in stiffness along its length, enabling the perception of different
frequencies of sound, also known as the place theory
, ⩥ cochlea. Answer: a snail-shaped, fluid-filled structure in the inner ear,
which contains hair cells that convert sound vibrations into electrical
signals for the brain to interpret
⩥ conductive deafness. Answer: impediments in the transmission of
sound waves through the middle ear to the cochlea, often caused by
diseases or bone growth; also known as middle-ear deafness
⩥ inner ear. Answer: the innermost part of the ear, which contains the
cochlea and vestibular system and is responsible for converting sound
vibrations into neural signals and maintaining balance
⩥ nerve deafness. Answer: a condition that results from damage to the
cochlea, hair cells, or auditory nerve, often leading to irreversible
hearing loss; also known as inner-ear deafness
⩥ Pitch. Answer: the perceived frequency of a sound wave, influencing
the perception of high or low tones in auditory stimuli
⩥ timbre. Answer: the unique characteristic of a sound that distinguishes
it from others, influenced by factors such as harmonics and instrument
type; also known as tone quality
