WebLike pacemaker neurons in central pattern generators, subtypes of cortical cells fire bursts of spikes (brief clusters of spikes) rhythmically at preferred frequencies. Bursting neurons have the potential to serve as pacemakers for synchronous network oscillations, and bursts of spikes may underlie or enhance neuronal resonance. WebUsing microfluorescence measurements of intraneuronal pH, in situ hybridization, as well as intracellular, extracellular, and K+-sensitive microelectrode recordings, we show now that the capability for synchronous gamma-frequency (20–80 Hz) firing in response to high-frequency stimulation (HFS) emerges abruptly in the rat hippocampus at approximately … bucs long course swimming championships
