Neuronal Oscillations in Cortical Networks
Clocks tick, bridges and skyscrapers vibrate, neuronal networks oscillate. Are neuronal oscillations an inevitable by-product, similar to bridge vibrations, or an essential part of the brain'sExpand

Theta Oscillations in the Hippocampus
Theta oscillations represent the "on-line" state of the hippocampus. The extracellular currents underlying theta waves are generated mainly by the entorhinal input, CA3 (Schaffer) collaterals, andExpand

The origin of extracellular fields and currents — EEG, ECoG, LFP and spikes
Neuronal activity in the brain gives rise to transmembrane currents that can be measured in the extracellular medium. Although the major contributor of the extracellular signal is the synapticExpand

  • 31 December 1989
Review of the normally occurring neuronal patterns of the hippocampus suggests that the two principal cell types of the hippocampus, the pyramidal neurons and granule cells, are maximally activeExpand

Brain-state- and cell-type-specific firing of hippocampal interneurons in vivo
Neural-network oscillations at distinct frequencies have been implicated in the encoding, consolidation and retrieval of information in the hippocampus. Some GABA (γ-aminobutyric acid)-containingExpand

Cellular bases of hippocampal EEG in the behaving rat
Rats implanted with recording and stimulating electrodes were trained to run in an activity wheel for a water reward. Unitary discharges and slow activity were recorded by a movable tungstenExpand

Accuracy of tetrode spike separation as determined by simultaneous intracellular and extracellular measurements.
Simultaneous recording from large numbers of neurons is a prerequisite for understanding their cooperative behavior. Various recording techniques and spike separation methods are being used towardExpand

Mechanisms of Gamma Oscillations in the Hippocampus of the Behaving Rat
Gamma frequency oscillations (30-100 Hz) have been suggested to underlie various cognitive and motor functions. Here, we examine the generation of gamma oscillation currents in the hippocampus, usingExpand
