A novel mode of neuronal cell communication implicated in learning!

There is evidence implicating gap junctions (electric connections between neurons) in the processes that synchronize the activity of large numbers of neurons in the brain. Michael Fanselow’s Lab just showed that they are also involved in hippocampal learning and memory and extinction. Hippocampal rhythms (theta) were also affected by manipulations that altered gap junction function. These results are significant because they implicate another fundamentally different form of neuronal communication in learning and memory.
