Cochlear Hair Cells are tuned to respond to different sound frequencies. These cells are arrayed in a tonotopic gradient, with low frequency responders at the apical end of the cochlea and high frequency responders at the basal end. Birds and reptiles uses alternative splicing of BK Channels as one facet of tuning these hair cells [...]

All sensory pathways require a stimulus (eg light, sound, etc) and a sensory receptor. Each type of sensory receptor has an adequate stimulus that is unique to that receptor. Receptors, specialized nerve endings of sensory neurons, where sensory impulses originate. Sensory receptors are divided into 5 major types based on the type of stimulus to [...]
