Thus high-frequency oscillations synchronize the activity of electrically coupled subsets of principal neurons within the well-documented synaptic network of the hippocampus.

Por lo tanto, a los 150 principales emisores, responsables de 90 del material particulado de origen industrial emitido en la regin, se les requiri que en un. Moreover, this synchronous activity is not mediated through the more commonly studied modes of chemical synaptic transmission, but is in fact a result of direct electrotonic coupling of neurons, most likely through gap-junctional connections.

Here we report that high-frequency network oscillations are present in rat brain slices in vitro, occurring as a brief series of repetitive population spikes at 150-200 Hz in all hippocampal principal cell layers. G.S Karthic himself has been guiding many students for ANTHROPOLOGY as an optional for many years.Quite a few students got very good marks and successfully cleared the toughest examination(IAS).Its lucid approach and course completion within limited time frame makes Anthropology an interesting. The synaptic bases of theta and gamma rhythms have been extensively studied but the cellular bases for high-frequency oscillations are not understood. G.S.Karthic is one of the leading coaching institute in India.

In the hippocampus, these discharges are categorized according to their frequency as theta (4-10Hz), gamma (20-80 Hz) and high-frequency (approximately 200 Hz) discharges, and they occur in relation to different behavioural states. Coherent oscillations, in which ensembles of neurons fire in a repeated and synchronous manner, are thought to be important in higher brain functions.
