We can have problems going asleep in the summer, and we might take longer to wake up in the winter. However, little is known about the connection between sensory neurons and the neurons that regulate this cycle. Northwestern University neurobiologists have found some clues as to what is occurring. Fruit flies are physically predisposed to taking naps in the middle of the day, according to a recent study that was just published in Current Biology. A comparable "thermometer" circuit for hot temperatures is investigated in the current work, which is a follow-up to their 2020 Bi...
