In practice, electrodes are placed at 8 precise tactile-points of the body to achieve a multi-segmental frequency analysis.
For each animal and tactile stimulation point (in vivo), PSTHs of MUA were computed.
That's a tactile reference point for me; I know I'm in the vicinity.
Taken together, these findings suggest that under static conditions matrix rigidity acts as a tactile set-point to regulate cell traction forces, but dynamic responses to stretch are governed by mechanisms that appear to be invariant with regard to changes of substrate stiffness.
The NDS evaluates general behavior and respiration (maximum, 40 points), cranial nerves function (maximum, 20 points), sensitivity to tactile stimuli (maximum, 10 points), motor function (maximum, 10 points), and coordination (maximum, 20 points).
There are a few brief images of bodies intertwined, some just-offscreen or cannily framed sex, but no real proximity, almost no closeups, no tactile sense, no point of view of either character toward the other.
Tactile acuity (two point discrimination TPD) is measured in the paravertebral lumbar region using a plastic caliper ruler between L1 and the iliac crest.
Two studies have additionally shown that making the perceived action more salient from a tactile or proprioceptive point of view by involving objects that are painful to touch (Morrison, Bach, et al. 2007) or movements that would be painful to perform (Costantini et al. 2005) causes increases of activity in SII and SI respectively.
