Synchronization of fast (30-40 Hz) spontaneous cortical rhythms during brain activation.
We investigated the synchronization of fast spontaneous oscillations (mainly 30-40 Hz) in anesthetized and behaving cats by means of simultaneous extra- and intracellular recordings from multiple neocortical areas. Fast Fourier transforms, auto- and cross-correlations, and spike- or wave-triggered averages were used to determine the frequency and temporal coherence of fast oscillations that out...
متن کاملSynchronization of fast (30-40 Hz) spontaneous oscillations in intrathalamic and thalamocortical networks.
The synchronization of fast (mainly 30 to 40 Hz) oscillations in intrathalamic and thalamocortical (TC) networks of cat was studied under ketamine-xylazine anesthesia and in behaving animals by means of field potential, extra- and intracellular recordings from multiple sites in the thalamic reticular (RE) nucleus, dorsal (sensory, motor, and intralaminar) thalamic nuclei, and related neocortica...
متن کاملNeuronal networks for induced '40 Hz' rhythms.
A fast, coherent EEG rhythm, called a gamma or a '40 Hz' rhythm, has been implicated both in higher brain functions, such as the 'binding' of features that are detected by sensory cortices into perceived objects, and in lower level processes, such as the phase coding of neuronal activity. Computer simulations of several parts of the brain suggest that gamma rhythms can be generated by pools of ...
متن کاملDynamic properties of corticothalamic neurons and local cortical interneurons generating fast rhythmic (30-40 Hz) spike bursts.
Fast spontaneous oscillations (mainly 30-40 Hz) characterize cortical and thalamic neuronal networks during behavioral states of increased vigilance and depend on cell depolarization under the influence of ascending activating systems. We investigated, by means of intracellular recording and staining in vivo, the properties of fast-oscillating cortical neurons from cat's motor and association a...
