Phantom limb phenomena are a demonstration that:
our perceptions are creations of the brain
our perceptions are not sensorial
our sensory cortex is also motor
Many sub-modalities exist within each sensory system.
True
False
The point where your optic nerves converge to exit the eye and into the brain is known as:
visual point
optic nerve
optic disc
lens
Rods are:
better able to transduce bright light
used for daytime vision
sensitive to dim light
Color is processed in a specialized pathway in the brain. Which cortical area is specialized in color processing?
V1
V4
V3
V2
Agnosia is the result of damage of:
geniculostriate pathway
tectopulvinar pathway
dorsal stream
The tectopulvinar pathway is important for:
detection and orientation of visual stimulation
pattern, color, motion recognition, conscious visual functions
object's spatial location relative to the viewer
The two-streams hypothesis is a model of the neural processing of both vision and hearing.
true
false
Echolocalization involves
identifying the source of air-pressure waves
identifying and locating objects by bouncing sound waves off them and the ability to detect the complexity of pressure waves
Which inner-ear structure contains the auditory receptor cells and therefore is the essential organ of hearing?
pinna
vestibular nerve
incus
cochlea
Proprioception is related to:
tactile perception of objects
perception of body location and movement
perception of pain, temperature and itch
Which system has a set of receptors in each inner ear that respond to body position and movement of the head?
limbic
dorsal
vestibular
posterior spinothalamic
Ageusia is:
loss of taste
loss of smell
loss of movement in the right limbs
The motor cortex:
controls whole-body movements requiring coordination
controls skilled movements of the mouth and limbs
contains the neural circuits for executing all movements
As part of the motor cortex, the prefrontal cortex:
specifies movement goals
generates plans for movements
define needed movement sequences
executes
Cells in the primate premotor cortex that fire when an individual observes a specific action taken by another individual are called:
imitation neurons
repeated neurons
mirror neurons
Hypokinesias result from damage in:
basal ganglia
premotor cortex
hypothalamus
spinal cord
Involuntary or exaggerated movements are associated with:
dyskinesias
hypokinesias
Damage in midline areas of the cerebellum do not disrupt balance, eye movements, or posture.
True
False
