Figure 1 The Sensory Arc of the Vibrissal Perceptual Loop, from Object Encounter to Neural Code From left to right: external objects are sampled by active scanning with the whisker array; spatial features of the object (e.g., location, shape, size, and texture) are dynamically represented by morphological variables of the encountering whisker (θ, angle; κ, curvature); morphological variables are translated to mechanical forces within the follicle (Ftan, tangential force; Fax, axial force; M, bending moment). The forces are sensed by a heterogeneous array of highly sensitive mechanoreceptors in the whisker’s follicle, which convert them into neural code transmitted to the brain via the trigeminal nerve. The right-most panels are modified from Ebara et al. (2017). Neuron 2017 94, 423-425DOI: (10.1016/j.neuron.2017.04.031) Copyright © 2017 Elsevier Inc. Terms and Conditions
