A Newfound Neuron Might Help Keep the Brain's Cells in Sync

For Vikaas Sohal, a neuroscientist at UC San Francisco, who was not involved in the work, the discovery of these cells might help the field move away from conflicts about gamma rhythms. If they really are clock-like cells, he says, then signs of their timekeeping should show up in the rhythm of the local field potential.
