The role of ear stone size in hair cell acoustic sensory transduction
Hearing and bodily balance are different sensations initiated by a common mechanism. Both sound- and head movement-dependent mechanical displacement are converted into electrical signals by the sensory hair cells. The saccule and utricle inner ear organs, in combination with their central projections to the hindbrain, are considered essential in fish for separating auditory and vestibular stimu...
متن کاملSensory Neuron Mechanotransduction, Mechanisms and Molecules Detecting Sound: Mechano-electrical Transduction in the Ear
Somatic sensation is overwhelmingly felt as the result of mechanical stimulation or movement of the body or its parts. Indeed almost all tissues of the body receive an innervation from the peripheral axons of mechanosensitive sensory neurons with their cell body in the dorsal root or trigeminal ganglia. Remarkably, the mechanisms and molecules used by sensory neurons to transform mechanical for...
متن کاملSensory Transduction: Confusing the Senses
Two new studies in the fruit fly Drosophila demonstrate unexpected molecular, and mechanistic, overlaps between the different senses. In the centre stand two long-established families of sensory proteins--rhodopsins and TRP channels.
متن کاملLazzaro and Mead — Circuit Models of Sensory Transduction in the Cochlea CIRCUIT MODELS OF SENSORY TRANSDUCTION IN THE COCHLEA
Nonlinear signal processing is an integral part of sensory transduction in the nervous system. Sensory inputs are analog, continuous-time signals with a large dynamic range, whereas central neurons encode information with limited dynamic range and temporal specificity, using fixed-width, fixed-height pulses. Sensory transduction uses nonlinear signal processing to reduce real-world input to a n...
متن کاملUnconventional Myosins in Inner-Ear Sensory Epithelia
To understand how cells differentially use the dozens of myosin isozymes present in each genome, we examined the distribution of four unconventional myosin isozymes in the inner ear, a tissue that is particularly reliant on actin-rich structures and unconventional myosin isozymes. Of the four isozymes, each from a different class, three are expressed in the hair cells of amphibia and mammals. I...
