...rhythm

A pronounced rhythm that dominates both EEG and unit activity throughout the nonprimate mammalian limbic system during exploratory activity, including that associated with learning. In hippocampus, the 2#2 rhythm coincides with a cycle of neuronal excitability suggesting that hippocampal processing may occur in discrete processing periods akin to clock cycles in digital computers.
