TLDR
The P38/N38 complex represents the primary cortical response to PTN stimulation and varies slightly from individual to individual in a manner consistent with a functional dipole situated in the leg and foot area on the mesial aspect of the postcentral gyrus.About:

Color imaging of parietal and frontal somatosensory potential fields evoked by stimulation of median or posterior tibial nerve in man
TL;DR: Somatosensory evoked potentials to median or fingers or posterior tibial nerve stimulation were recorded with earlobe reference in normal young adults with characteristic focal distribution suggesting that they reflected one or more generators in cortical areas.

TL;DR: Somatosensory evoked potentials (SEPs) were elicited by stimulation of the right posterior tibial nerve at the ankle in 20 experiments on 18 normal adults and several positive far fields with widespread scalp distribution and stationary latencies have been identified.

TL;DR: Methods of localizing functional regions of the mesial wall are described, based on 47 patients studied intraoperatively or following chronic implantation of subdural electrodes, which revealed a rough somatotopic organization within the SMA and little evidence of the "pre-SMA" region described in monkeys.

TL;DR: The CV of the STT was measured by recording somatosensory evoked potentials following CO2 laser stimulation of the hand and foot, which was previously shown to cause pain or heat sensation by activating cutaneous nociceptors and by its ascending signals through A delta fibers and probably STT.

TL;DR: It is believed that optimal monitoring during spinal surgery requires recording both SEPs and MEPs, which provides independent verification of spinal cord integrity using two parallel but independent systems, and also allows detection of the occasional insults that selectively affect either motor or sensory systems.

TL;DR: Early somatosensory evoked potential components to median nerve or finger stimulation were recorded with non-cephalic references in normal young adults to identify spinal entry time with the onset of the neck N11 or scalp P11 and suggest that FF3-FF4 are generated in medial lemniscus rather than above the thalamus.

TL;DR: The changes associated with normal aging have been confirmed and extended and a new widespread component N18 was identified and shown to be generated below the cortex.

TL;DR: The use of 14 simultaneous recordings including a series of pre- and post-vertebral electrodes clearly identified two distinct generators for the spinal SEP components to median nerve stimulation: a presynaptic generator which ascends the dorsal column (N 11 ) and a postsynaptic fixed generator in the dorsal horn of the cervical spinal cord (N 13 -P 13).
