Question

which part of the cns sorts almost all sensory information ascending to the cerebral cortex?
hypothalamus
thalamus
midbrain
pons

Explanation:

To solve this, we analyze each option:

• Hypothalamus: Mainly regulates hormones, homeostasis, not sensory sorting.
• Thalamus: Acts as a relay station, sorting almost all sensory info to cerebral cortex.
• Midbrain: Involved in visual/audio reflexes, not primary sensory sorter.
• Pons: Regulates sleep, breathing, not sensory sorting.

Answer:

B. thalamus
