AOTA AOTA Neuroscience & Brain Development 2 — Questions and Answers
Question 1: The limbic system's primary role in sensory integration involves:
- Fine motor coordination of the hands
- Emotional and arousal responses to sensory input (Correct answer)
- Visual-spatial processing
- Language comprehension
Correct answer: Emotional and arousal responses to sensory input
The limbic system modulates emotional and arousal reactions to sensory stimuli, shaping behavioral responses.
Question 2: Myelination of sensory pathways is developmentally significant because it:
- Decreases overall sensory sensitivity
- Increases the speed and efficiency of neural signal transmission (Correct answer)
- Reduces neuroplasticity in adulthood
- Prevents sensory habituation
Correct answer: Increases the speed and efficiency of neural signal transmission
Myelination enhances neural conduction velocity, allowing faster and more reliable transmission of sensory information.
Question 3: The vestibulo-ocular reflex (VOR) stabilizes gaze during head movement through connections between:
- Vestibular system and visual system (Correct answer)
- Proprioceptive system and auditory cortex
- Tactile system and motor cortex
- Olfactory and gustatory systems
Correct answer: Vestibular system and visual system
The VOR maintains stable vision during head movement via direct connections between vestibular nuclei and oculomotor nuclei.
Question 4: Interoception provides the nervous system with information about:
- Body position and movement in space
- The physiological state of internal body organs (Correct answer)
- External tactile surface contact
- Balance and linear acceleration
Correct answer: The physiological state of internal body organs
Interoception conveys signals about the internal body's condition, including heart rate, hunger, pain, and organ states.
Question 5: Ayres' sensory integration dysfunction hypothesis proposes that sensory processing deficits arise primarily from:
- Peripheral nerve damage at the receptor level
- Inefficient neural organization within the central nervous system (Correct answer)
- Environmental deprivation during early childhood
- Nutritional deficiencies affecting myelination
Correct answer: Inefficient neural organization within the central nervous system
Ayres theorized that SI disorders stem from inefficient neural processing and organization within the CNS, not peripheral factors.
Question 6: Bilateral integration in sensory integration theory requires coordination of:
- Visual and auditory processing streams
- Both cerebral hemispheres and both sides of the body (Correct answer)
- Vestibular and tactile systems only
- Interoceptive and proprioceptive systems
Correct answer: Both cerebral hemispheres and both sides of the body
Bilateral integration involves coordinated communication between both brain hemispheres and both body sides for skilled, coordinated movement.
