Soma area measurements of parvalbumin-positive neurons, their distribution patterns within a given auditory nucleus and in some cases also the configuration of their basal dendrites, indicate that parvalbumin-immunoreactivity is not restricted to one morphologically defined neuron population, but rather labels subpopulations of morphologically and/or physiologically defined neuron types. It is made up of both peripheral structures (e.g., outer, middle, and inner ear) and brain regions (cochlear nuclei, superior olivary nuclei, lateral lemniscus, inferior colliculus, medial geniculate nuclei, and auditory cortex). Unanesthetized cats with electrodes permanently implanted along the auditory pathway were presented first with sustained white noise stimuli and then with. All nuclei of the auditory pathway expressed numerous neurons, which are imunoreactive with parvalbumin antiserum, with the exception of the meidal geniculate body, which is characterized by parvalbumin-positive neuropil. The auditory system processes how we hear and understand sounds within the environment. The critical step for understanding the pathophysiology of hearing disorders is to identify genes and molecular pathways that are crucial in generating auditory. It passes through the major subcortical areas, which are characterized by groups of neurons known as nuclei, the plural of nucleus. Psychology Definition of AUDITORY PATHWAYS: the auditory-specific neural structures that convey auditory information from the cochlear hair cells to the. The distribution of neurons containing the calcium-binding protein parvalbumin was mapped in the subcortical auditory system of the mongolian gerbil. There is a collection of tracts that connects the cochlea to primary auditory cortex, known as the central auditory pathway. Auditory learning is a style of learning in which an individual learns more efficiently by listening.
