Figure 8. Diagram of signal flow within loops that encompass vM1 cortex in the vibrissa sensorimotor system.

Figure 8

We shown only the subset of sensorimotor pathways that encompass the known flow of spike-based signaling in the rodent (Chakrabarti and Alloway, 2006; Kleinfeld et al., 2006; Urbain and Deschênes, 2007); the diagram is thus incomplete, especially with regard to basal ganglia (Hoffer et al., 2005) and cerebellar circuits (Lang et al., 2006; O'Connor et al., 2002). Minus signs mark inhibitory pathways. The brainstem nuclei include a hypothetical central pattern generator. Symbols: VPM, ventral posterior medial thalamus; PO, posterior medial thalamus, ZIvmot and ZLvvib, motor and vibrissa subdivision, of ventral zona incerta, respectively. Functional projections are labeled in blue.
