Sensation refers to the detection of physical energy by sense organs, which then send information to the brain. Perception is the (cid:271)(cid:396)ai(cid:374)(cid:859)s i(cid:374)te(cid:396)p(cid:396)etatio(cid:374) of (cid:396)a(cid:449) se(cid:374)so(cid:396)(cid:455) i(cid:374)puts. Two sides of the coin: sensation and perception. Our brain picks and chooses the types of sensory information it uses and processes. Errors in perception show us which part of our sensory experiences are accurate and what is filled in. Transduction is the process of converting an external energy or substance into electrical activity within neurons. Sense receptors are specialized cells responsible for converting external stimuli into neural activity for a specific sensory system. Specialized cells at the back of the eye transduce light. Endings attached to axons embedded in deep layers of skin transduce pressure. Cells in a spiral shape organ in the ear transduce sound.
