Your brain, emotion and timing...

Your timing is subjective…turning your varying subjective internal clock into an objectively acceptable predictable and dance-able drum groove takes years.

The insular cortex, particularly the anterior part, plays a role in processing time intervals, especially in the range of seconds to subseconds, and is involved in both automatic and cognitively controlled temporal judgments. 
Here's a more detailed explanation:
Time Perception and the Insula:
The insular cortex, especially the anterior portion, is implicated in processing time intervals, including those in the range of seconds to subseconds. 
Short-Timescale Perception:
Studies suggest that the insula is involved in tasks requiring judgments of short periods of time (a few seconds or less). 
Interoception and Time:
Some models propose that the insula integrates changing body state signals to generate our sense of time duration, suggesting a link between interoception and time perception. 
Accumulator-Type Activity:
Research indicates that the posterior insula may exhibit accumulator-type activity, where neural activity accumulates over time, potentially encoding duration in the multiple seconds range. 
Cross-Modal Timing:
The anterior insula has been shown to respond to cross-modal timing mismatches, such as discrepancies between auditory and visual stimuli, even at intervals of 150 milliseconds or less. 
Other Brain Regions:
While the insula is involved in time perception, it's not the only brain region involved, and other structures may be more strongly associated with core timing functions.
