,1. What is the role of the superior colliculus in visual processing?
A) Color perception
B) Depth perception
C) Motion detection
D) Visual attention
Correct Answer: D) Visual attention
Rationale: The superior colliculus is primarily involved in the
initiation of visual attention and eye movements.
2. Which structure is responsible for the transduction of sound
waves into neural signals?
A) Tympanic membrane
B) Cochlea
C) Auditory nerve
D) Eustachian tube
Correct Answer: B) Cochlea
Rationale: The cochlea contains hair cells that convert
mechanical sound waves into electrical signals that the brain can
interpret.
,3. In the context of sensory adaptation, which statement is true?
A) It occurs when a stimulus is too weak to be detected.
B) It prevents the detection of new stimuli.
C) It involves an increase in sensitivity to a constant stimulus.
D) It results in a decreased response to a constant stimulus.
Correct Answer: D) It results in a decreased response to a
constant stimulus.
Rationale: Sensory adaptation refers to the diminished
sensitivity to a constant stimulus over time.
4. The 'blind spot' in the human visual field is due to:
A) The fovea centralis lacking rods and cones.
B) The absence of photoreceptors where the optic nerve exits
the eye.
C) The optic chiasm blocking part of the field of view.
D) A deficit in color vision.
Correct Answer: B) The absence of photoreceptors where the
optic nerve exits the eye.
Rationale: The blind spot occurs where the optic nerve exits the
retina, creating an area without photoreceptors, hence no image
detection.
, 5. Which of the following is a chemical sense?
A) Vision
B) Hearing
C) Taste
D) Touch
Correct Answer: C) Taste
Rationale: Taste is a chemical sense because it involves the
detection of chemical molecules in food.
6. The phenomenon of 'phantom limb sensation' best supports
which of the following concepts?
A) The brain's plasticity in reorganizing sensory information.
B) The importance of proprioceptors in the limbs.
C) The role of the skin in sensory perception.
D) The necessity of actual limb presence for sensation.
Correct Answer: A) The brain's plasticity in reorganizing
sensory information.
Rationale: Phantom limb sensation occurs because the brain
reorganizes and adapts to the loss of the limb, yet still receives
signals as if the limb were present.
