Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.
Computational modelling shows that coupled theta and gamma oscillations in the auditory cortex can decompose speech into its syllabic constituents, and organize the neural spiking at faster timescale into a decodable format.
Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.
Inhibitory noninvasive stimulation to the precuneus disrupts theta and gamma oscillatory coupling between medial temporal lobes and neocortical regions during complex personal memory retrieval.
The hippocampus features a double dissociation in its circuits with respect to the regulation of fear and anxiety, with CA3 and the dentate gyrus implicated in anxiety and CA1 in fear.
Brain imaging reveals frequency-dependent lateralized rhythmic finger tapping control by the auditory cortex with left-lateralized control of relative fast and right-lateralized control of relative slow rhythms.
Different rhythms uniquely contribute to task-related processing in the hippocampus, and changes in the rhythmic profile of the hippocampus reflect dynamic coordination of its cell activity.
A combination of signal processing and machine learning form a new approach to classify oscillatory coupling in single cycles without averaging over time and to capture cycle-by-cycle changes in coupling.
