CBNS 106 Practice Test Questions &
Answers 2024/2025
Objects in the EXTREME RIGHT (far right periphery) of your visual world: - ANSWERS-stimulate nasal
hemiretina of your right eye
-are represented in the left primary visual cortex
the lateral geniculate nucleus on the right side of the brain - ANSWERS-contains a complete
representation of the left visual world
-receives input from the nasal hemiretina of the left eye
a lesion in the UPPER BANK of the calcarine fissure in the PRIMARY VISUAL CORTEX on the RIGHT side of
the brain will cause: - ANSWERSloss of vision in the LOWER LEFT quadrant of the visual field of both eyes
cutting the RIGHT OPTIC NERVE will cause: - ANSWERSblindness to the RIGHT eye
the central portion of the left side of the visual field is represented: - ANSWERSin the right primary visual
cortex at the most posterior portion of the calcarine fissure
adding glutamate to a slice of the cat spinal cord maintained in a dish: - ANSWERS-causes alternate
bursting in left and right ventral roots
-mimics the effects on activity in the ventral roots of dorsal root stimulation
CPGs in the vertebrate spinal cord: - ANSWERS-can be switched on by sensory input
-can be activated by stimulation of the mesencephalic locomotor nucleus
-can be modulated by coordinating fibers from other CPGs
in a mesencephalic cat suspended on a treadmill, which of the following is true? - ANSWERSthe animal
will walk faster as the stimulation current delivered to the MLn is increased
, stimulation of cat mesencephalic locomotor nucleus should: - ANSWERS-produce a pattern of walking,
trotting and galloping as the current intensity is increased
-result in activation of spinal central pattern generators for locomotion
-result in an alternating pattern of activity in corresponding left and right ventral roots
-result in an alternating pattern of activity in alpha motor neurons innervating the left and right legs
when a person is asked to perform a complex sequence of finger movements and brain activity is
recorded by PET - ANSWERS-primary motor cortex will show increased activity
-supplementary motor cortex show increased activity
the expression "running around like a chicken with your head cut off" is derived from farmers
observations that chickens run around vigorously for several seconds after they are decapitated. this
observation suggests that: - ANSWERS-motor neurons to the muscles generating locomotor movements
originate in the spinal cord
-locomotor behavior can be produced and organized by neural circuits within the spinal cord
the central pattern generator producing respiration in the mollusk lymnaea: - ANSWERScan form normal
connections in vitro
the inferotemporal cortex "face recognition" neurons - ANSWERSshow a particular across neuron pattern
of responses to a particular face
someone suffering from prosopagnosia - ANSWERShas an impaired ability to recognize faces
for a mesencephalic cat, transecting the spinal cord between the hindlimbs and forelimbs: -
ANSWERSdisrupts the rhythm between the forelimbs and hindlimbs when the cat is on the treadmill
sensory fibers conveying information to the central nervous system may: - ANSWERS-ascend in the spinal
cord to the brain
-synapse on the interneurons in the spinal cord
-synapse on neurons in the ventral horn which innervate skeletal muscles
