“These cells are encoding information related to time, and this information is clearly important for memory,” Dr. Lega mentioned.

In impact, Dr. Lega mentioned, the cells representing time fired to help an exercise, on this case to trace the passage of the 30-second interval. There isn’t any fixed rhythm or background beat; the time sign is conjured as wanted. “There’s no internal metronome, or clock,” he mentioned. The time cells are “firing to support what you’re doing.”


That is, time cells alter to the calls for being made on the mind, in actual time, second to second. Another group of close by neurons, known as ramping cells, accelerates its firing as a job begins and decelerates or decays as the job winds down, marking off chunks of time. “As these cells are sensitive to contextual changes during experience, they could represent the slowly evolving nature of contextual information,” the authors write.
