Damage to third order somatosensory neurons would directly prevent transfer of information between which two brain regions, respectively?
A) primary somatosensory cortex to thalamus
B) peripheral somatosensory receptors to medulla
C) primary somatosensory cortex to somatosensory association area
D) thalamus to primary somatosensory cortex

Question

Quizplus · Accepted Answer

Third order somatosensory neurons are responsible for carrying information from the thalamus to the primary somatosensory cortex. Therefore, damage to these neurons would prevent transfer of information between the thalamus and primary somatosensory cortex. Choices A, B, and C involve transfer of information between different regions, but not specifically between the thalamus and primary somatosensory cortex.
