Sensory neurons and circuits mediating itch

摘要: Chemicals that are used experimentally to evoke itch elicit activity in diverse subpopulations of cutaneous pruriceptive neurons, all which also respond painful stimuli. However, is distinct from pain: it evokes different behaviours, such as scratching, and originates the skin or certain mucosae but not muscle, joints viscera. New insights regarding neurons mediate sensation have been gained experiments gene expression has manipulated types well comparisons between psychophysical measurements neuronal discharges other properties peripheral central neurons.
