An intimate Vulcan technique of applying pressure to nerve clusters to relax body and mind, which T'Pol used to treat Trip Tucker's insomnia in the Delphic Expanse.
Neuropressure is a demanding Vulcan discipline in which precise pressure on neural nodes relieves tension and helps the patient sleep. Done wrongly it can cause harm, and it requires both people to be partly undressed, which most Vulcans would find far too personal to share with an outsider.
In the Enterprise episode The Xindi, Trip Tucker has barely slept since his sister died in the attack on Earth. Phlox, unwilling to keep sedating him, manoeuvres him and T'Pol into trying the treatment. The sessions continue through the third season, and Trip learns to return the favour.
The nightly routine becomes the basis of their romance. In Harbinger, T'Pol is provoked when Trip practises the technique with a MACO corporal, Amanda Cole, and the two spend the night together.
