Comparison of TIP characteristics between the modeled TIP-inducing mechanisms and head-fixed rats.

The presented values, of both the simulations and the rat, are of TIPs induced by contacts at a radial distance of 40% from the base of the touching whisker. Values of simulated TIPs that were induced by contacts at a wide range of radial distances (20–70%) are displayed in brackets. For each TIP-inducing mechanism, values were obtained while using either one of two whisking-evoking mechanisms: generation of whisking by CPG alone or by both the CPG and sensory feedback. *∼10° for all non-touching whiskers in rows A–E, except for the most rostral whiskers in rows C–E, which retracted by ∼5°. **Observed in both head-fixed and behaving rats. In head-fixed rats, TIP was observed in the two additional non-touching whiskers that where examined [11]; in behaving rats TIP was observed in all the whiskers found on the same row as the touching whisker.
