What Can a Cell Remember?
Then, in a process Kukushkin described as a tedious choreography of clockwork pipetting, they exposed the cells to precisely timed bursts of chemicals that imitated bursts of neurotransmitters in the brain. Kukushkin’s team found that the both the nerve and kidney cells could finely differentiate these patterns. A steady three-minute burst activated CRE, making the cells glow for a few hours. But the same amount of chemicals, delivered as four shorter pulses spaced 10 minutes apart, lit up the p
