What Makes Subcortical Barrels

摘要: The spatial arrangement of the mystacial vibrissae, or whiskers, on rodent’s face is represented in most trigeminal (V) neuraxis by patterning afferent terminals, neuronal somata, and dendritic processes, which appears as an array patches cell rings (see Fig. 1 Woolsey, 1990). In layer IV cerebral cortex, aggregates are referred to barrels (Woolsey Van der Loos, 1970). ventroposteromedial thalamic nucleus, whisker-related groupings barreloids (Van 1976). V brainstem nuclear complex, analogous clusters called barrelettes (Ma, 1991), they occur subnuclei principalis (PrV), interpolaris (SpVi), caudalis (SpVc). three dimensions, subcortical patterns appear columns terminals postsynaptic processes running rostrocaudally complex obliquely thalamus. axons cells within each column best responsive somatotopically appropriate whisker.
