#tweeprint! Have you ever wanted to learn about spatial and non-spatial hippocampal function, especially in primates? We look at single neurons + ensemble activity across tasks during virtual navigation in a new paper with @JulioMTneuro in @NatureNeuro nature.com/articles/s41593-0… 1/

You might notice that the theta band defined here (7-9+ Hz) is higher in frequency than what rodent electrophysiologists call "theta" (~3-8 Hz). The cross-species difference in naming can be traced to Stewart and Fox, 1991, Brain Research.

The authors suggest that these results may show a link between saccades and neural information processing. Though these results are correlational, they might suggest that phase-resetting associated with saccades can "establish optimal conditions for synaptic plasticity".

This paper is focussed on description of power and phase changes around fixation onset in humans and monkeys. All of the results are related to analysis of the local field potentials. Implications on single-neuron activity were also discussed...

Previous literature suggests that theta-phase resets occur without increased spiking (e.g. Zugaro et al 2005). Phase resets may be accompanied with increases in spike-field coherence, which predicted performance in human patients doing a memory task (Rutishauser et al 2010).
