Sensory receptors convert energy into neural impulses. Brain must know what is happening in order to react. Detect and respond to various stimuli (modality speci c) Intensity (how much/ strong) will in uence action potential (how bright, loud) Di erence between not bing able to perceive stimulus and being able to just barely perceive it.

Wavelengths dictate colours we see and don"t see. Cones are receptive to light; in centre; useless at night. Blind spot where optic nerve leaves eye.
