The right hemisphere of the brain processes signals from sensory nerves on the left side of the body. Another way to say this is that sensory neurons are located ________________ to the hemisphere of the brain that processes them.
A

B
Medial
C
Contralateral
D
Lateral
Verified step by step guidance1
Understand the concept of lateralization in the brain, where each hemisphere is responsible for processing signals from the opposite side of the body.
Identify the term 'contralateral,' which refers to the opposite side. In this context, it means that the right hemisphere processes signals from the left side of the body.
Recognize that 'ipsilateral' would mean the same side, which is not applicable here since the right hemisphere processes signals from the left side.
Consider the term 'medial,' which refers to structures located towards the midline of the body, not relevant to the lateralization of brain function.
Understand that 'lateral' refers to structures located away from the midline, but does not specifically address the cross-hemisphere processing of sensory signals.
