The receptors under study provide transfer of information to the cortex without thalamic involvement. Specify these receptors:

Answer options

1. Auditory
2. Visual
3. Gustatory
4. Tactile
5. Olfactory

Explanation

The receptors under study provide transfer of information to the cortex without thalamic involvement. Specify these receptors:Tactile – 1st and 2nd neurons are in the spinal cord and 3rd is VPM (ventral posterior medial nucleus) of the thalamus. Gustatory– Terminate in the medial half of VPM. Visual- About 90% of axons in the optic nerve go to the lateral geniculate nucleus of the thalamus. Auditory passes through the medial geniculate body which is part of the thalamic system. So we are left with OLFACTORY which is the correct answer.
