Significats de oscillatory activity en anglès

Gamma-frequency oscillatory activity plays an important role in information integration across brain areas.

Both event-related potentials and task-related oscillatory activity were investigated.

A number of neurological and psychiatric disorders-including Parkinson's disease, autism, depression, schizophrenia, and anxiety-are associated with abnormalities in oscillatory activity.

Hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels have important functions in controlling neuronal excitability and generating rhythmic oscillatory activity.

In particular, oscillatory activity in the delta and theta frequency range has been associated with the generation of the P300 component.

Using patch-clamp techniques, we investigated the characteristics of the spontaneous oscillatory activity displayed by starburst amacrine cells in the mouse retina.

These findings suggest that during a relapse situation reduced synchronous oscillatory activity of the local neural population in the nucleus accumbens shell occurs.

Results: We find a decreased amplitude in the response to auditory stimuli and reduced recruitment of neurones to fast steady-state gamma oscillatory activity.

After a brief non-dopamine-specific desynchronization, oscillatory activity first increased during HVS followed by progressive motor impairment and the shortening of SNr activation delay.

Thus, our data suggest that FS interneurons might not be involved in generating cortical oscillatory activity and γ oscillations during the first postnatal week.

At the macroscopic level, we summarize evidence that this excitatory ictal wave activity is strongly correlated with oscillatory activity across a centimeter-sized cortical network.

The conclusion of the present study is that long-range coherent oscillatory activity in the theta band reflects top-down activation rather than global WM functions.

Certain clinical features of schizophrenia, such as working memory disturbances, appear to emerge from altered gamma oscillatory activity in the prefrontal cortex (PFC).

Chronic DBS of either the EPN or the Pf improved dyskinesia scores in HP-LID rats, and no differences in oscillatory activity were observed between groups.

We studied the existence, localization and attentional modulation of gamma-band oscillatory activity (30-130 Hz) in the human intracranial region.

We employed transcranial magnetic stimulation-electroencephalography (TMS-EEG) over parietal regions across states of anesthesia and sleep to assess whether evoked oscillatory activity differed in disconnected states.
