Subthalamus
Part of the VP complex that relays sensation from the face

___ is the process in which a stimulus for which a receptor is specialized is transformed by the receptor membrane into a receptor potential
Transduction
This theory states that different receptors detect each different quality of sensation
Doctrine of specific nerve energies
This theory states that separate neural channels carry information from the specific receptors to the place in the brain by which is the site of sensation
