Peripheral afferents

WebFeb 15, 2006 · STRFs of peripheral afferents consist of a rapidly appearing excitatory region followed by an in-field (replacing) inhibitory region. STRFs of SA1 afferents also exhibit flanking (surround) inhibition that can be attributed to skin mechanics. WebAfferent Mechanoreceptor Classification • Mechanoreceptors are sensory neurons or peripheral afferents located within joint capsular tissues, ligaments, tendons, muscle, and skin. • Four primary types of afferent mechanoreceptors are commonly present in noncontractile capsular and ligamentous structures in human joints: types I, II, III, and IV. •
