Mounting evidence indicates that a key functional property of these oscillations is the rhythmic shifting of excitability in local neuronal ensembles. Here, we show that when attended stimuli are in a rhythmic stream, delta-band oscillations in the primary visual cortex entrain to the rhythm of the stream, resulting in increased response gain for task-relevant events and decreased reaction times. Because of hierarchical cross-frequency coupling, delta phase also determines momentary power in higher-frequency activity. These instrumental functions of low-frequency oscillations support a conceptual framework that integrates numerous earlier findings.}, year = {2008}, eissn = {1095-9203}, pages = {110-113}, orcid-numbers = {Ulbert, István/0000-0001-9941-9159} } @article{MTMT:1031129, title = {Firing rate and theta-phase coding by hippocampal pyramidal neurons during 'space clamping'.}, url = {https://m2.mtmt.hu/api/publication/1031129}, author = {Hirase, H and Czurkó, András and Csicsvari, J and Buzsáki, György}, doi = {10.1046/j.1460-9568.1999.00853.x}, journal-iso = {EUR J NEUROSCI}, journal = {EUROPEAN JOURNAL OF NEUROSCIENCE}, volume = {11}, unique-id = {1031129}, issn = {0953-816X}, abstract = {In the hippocampus, spatial representation of the environment has been suggested to be coded by either the firing rate of pyramidal cell assemblies or the relative timing of the action potentials during the theta EEG cycle. Here, we used a behavioural 'space clamp' method, which involved the confinement of the actively running animal in a defined position in space (running wheel) to examine how 'spatial' and other inputs affect firing rate and timing of hippocampal CA1 pyramidal cells and interneurons. Nineteen per cent of the recorded CA1 pyramidal cells were selectively active while the rat was running in the wheel in a given direction ('wheel' cells). Spatial rotation of the apparatus showed that selective discharge of pyramidal cells in the wheel was under the combined influence of distal and apparatus cues. During steady running, both discharge rate and theta phase were constant. Rotation of the wheel apparatus resulted in a shift of both firing rate and preferred theta phase. The discharge frequency of 'wheel' cells increased threefold (on average) with increasing running velocity. In contrast, change in running speed had relatively little effect on the theta phase-related discharge of 'wheel' cells. Our findings indicate that mechanisms that regulate rate and phase of spikes are overlapping but not necessarily identical.}, year = {1999}, eissn = {1460-9568}, pages = {4373-4380}, orcid-numbers = {Czurkó, András/0000-0002-1985-7296} }
