functions. These network activity patterns have been described across multiple animal …

Local field potentials: myths and misunderstandings

O Herreras - Frontiers in neural circuits, 2016 - frontiersin.org
The intracerebral local field potential (LFP) is a measure of brain activity that reflects the
highly dynamic flow of information across neural networks. This is a composite signal that …

Complementary learning systems within the hippocampus: a neural network modelling approach to reconciling episodic memory with statistical learning

AC Schapiro, NB Turk-Browne… - … of the Royal …, 2017 - royalsocietypublishing.org

Respiration-entrained brain rhythms are global but often overlooked

ABL Tort, J Brankačk, A Draguhn - Trends in neurosciences, 2018 - cell.com
We revisit recent evidence showing that nasal respiration entrains oscillations at the same
frequency as breathing in several regions of the rodent brain. Moreover, respiration …

Theta phase segregation of input-specific gamma patterns in entorhinal-hippocampal networks

EW Schomburg, A Fernández-Ruiz, K Mizuseki… - Neuron, 2014 - cell.com

interregional coordination of gamma oscillations using high-density electrophysiological …

Theta oscillations in the hippocampus

G Buzsáki - Neuron, 2002 - cell.com
Theta oscillations represent the" on-line" state of the hippocampus. The extracellular
currents underlying theta waves are generated mainly by the entorhinal input, CA3 …

Gamma (40-100 Hz) oscillation in the hippocampus of the behaving rat
