Some cones have their own bipolar cell to which they connect. This is not the case in peripheral vision, however. 20degrees away from the fovea, tens or hundreds of rods in the periphery converge onto a single bipolar cell, causing loss of information because a bipolar cell cannot tell which rod triggered it 1 million ganglion cells Sensation: reception of stimulation from the environment and the initial encoding of that stimulation into the nervous system Perception: process of interpreting and understand sensory information Controlled attention: forms of processing in which there is a deliberate, voluntary allocation of mental effort or concentration.
