The thermal grill elicited a complex percept, which was distinguished almost perfect from a hot stimulus.
Pain-related sensations were less present in the grill percept than in a single hot stimulus near pain threshold.
Females experienced significantly stronger magnitude sensations to the cold than the hot stimulus (5.5 ± 1.7 and 4.3 ± 1.3, p < 0.05, respectively).
We hypothesized that the thermal grill would be perceived as different from a single temperature hot stimulus near pain threshold because of varying sensory qualities.
Instead of getting obsessed with the marshmallow — the "hot stimulus" — the patient children distracted themselves by covering their eyes, pretending to play hide-and-seek underneath the desk, or singing songs from "Sesame Street".
Does it "confer analgesia," thus beating out pain? Students who volunteered for the study were asked to stare at a photo of their new beloved while researchers inflicted a "painfully hot stimulus".

The pattern of perceived qualities of the thermal grill differed from single temperature warm and hot stimuli.
In temperature a heat differential stimulates certain other receptors: relative cold stimulates the Krause end-bulbs, while relative warmth stimulates the Ruffini end-organs; "hot" stimuli stimulate both kinds of receptors.
The aim of this pilot study was to examine the blood oxygen level dependent (BOLD) changes induced by an experimental pain tolerance (endure) hot stimuli vs. non-painful stimuli in clinically stable patients with schizophrenia and in healthy controls.
A cold stimulus was found to intensify the sensation evoked by lingual IBA whereas warm and hot stimuli were found to have no effect.
The rest 490 neurons had no response to hot water stimulus at 48°C (accounting to 75.04% of the total neurons recorded).
