Highlights

Modelling foot sole cutaneous afferents: FootSim

Katic N, Siqueira RK, Cleland LD, Strzalkowski N, Bent L, Raspopovic S, Saal HP

We developed a Python simulator that recreates realistic neural responses from tactile afferents terminating in the sole of the foot.

Expansion and contraction of resource allocation in sensory bottlenecks

Edmondson LR, Jimenez Rodriguez A, Saal HP

We show that a simple efficient coding model predicts complex trade-offs in resource allocation for sensory inputs with heterogeneous receptor densities and activation levels. These results provide a theoretical framework that explains why some body regions are magnified in somatosensory cortex.

Tactile innervation densities across the whole body

Corniani G, Saal HP

This paper contains estimates for innervation densities of low-threshold mechanoreceptive afferents across the whole body, based on evidence from microneurography, histology, and immunohistochemistry.
