Abstract

The neural coding of perception can differ from that for the physical attributes of a stimulus. Recent studies suggest that activity in right anterior insular cortex may underlie thermal perception, particularly that of cold. We now examine whether this region is also important for the perception of warmth. We applied cutaneous warm stimuli on the left leg (warmth) in normal subjects (n = 7) during functional magnetic resonance imaging (fMRI). After each stimulus, subjects rated their subjective intensity of the stimulus using a visual analogue scale (VAS), and correlations were determined between the fMRI signal and the VAS ratings. We found that intensity ratings of warmth correlated with the fMRI signal in the right (contralateral to stimulation) anterior insular cortex. These results, in conjunction with previous reports, suggest that the right anterior insular cortex is important for different types of thermal perception.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 March 2022.
All research outputs
#8,534,976
of 25,373,627 outputs
Outputs from Neuroscience Letters
#2,300
of 7,756 outputs
Outputs of similar age
#26,896
of 76,667 outputs
Outputs of similar age from Neuroscience Letters
#24
of 81 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,756 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one is in the 39th percentile – i.e., 39% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 76,667 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 81 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
