Definitions:

Cones

Sensory receptors in the retina that detect light waves and transduce them into signals that are processed in the brain as vision. Cones respond best to higher levels of illumination, and therefore they are responsible for seeing color and fine detail.

Rods

Sensory receptors in the retina that detect light waves and transduce them into signals that are processed in the brain as vision. Rods respond best to low levels of illumination, and therefore they do not support color vision or seeing fine detail.

Transduction

The process of converting one form of energy into another. In sensory systems, it refers to the conversion of external stimuli into nerve signals.

Sensory Adaptation

The process by which sensory receptors become less responsive to constant stimuli, allowing individuals to ignore background levels of stimulation.
