Memory Leans More on the Brain’s Electric Field Than on Neurons

MIT researchers compare the electric field to an orchestra conducting the neurons as players

The Picower Institute for Learning and Memory at MIT offers an interesting new model of how memories are processed in the brain. Using two macaques playing a game while their brain activities were recorded, the researchers suggest the orchestra as a model. The neurons are the players and the electric field is the conductor: As the brain strives to hold information in mind, such as the list of groceries we need to buy on the way home, a new study suggests that the most consistent and reliable representation of that information is not the electrical activity of the individual neurons involved but an overall electric field they collectively produce. Indeed, whenever neuroscientists have looked at how brains represent information in…
