Understanding Epileptiform After-Discharges as Rhythmic Oscillatory Transients
Electro-cortical activity in patients with epilepsy may show abnormal rhythmic transients in response to stimulation. Even when using the same stimulation parameters in the same patient, wide variability in the duration of transient response has been reported. These transients have long been considered important for the mapping of the excitability levels in the epileptic brain but their dynamic...
متن کاملMorphine induces synchronous oscillatory discharges in the rat locus coeruleus.
The noradrenergic locus coeruleus (LC) plays a role in opioid dependence and withdrawal. In the present study, using a multiple-electrode recording technique that allowed several LC neurons to be recorded simultaneously over long time periods, LC neuronal activities were recorded before and after intracerebroventricular injection of morphine (26 nmol) under halothane anesthesia. We found that m...
متن کاملLight-evoked oscillatory discharges in retinal ganglion cells are generated by rhythmic synaptic inputs.
In the visual system, optimal light stimulation sometimes generates gamma-range (ca. 20 approximately 80 Hz) synchronous oscillatory spike discharges. This phenomenon is assumed to be related to perceptual integration. Applying a planar multi-electrode array to the isolated frog retina, Ishikane et al. demonstrated that dimming detectors, off-sustained type ganglion cells, generate synchronous ...
متن کاملCaV2.3 Channels Are Critical for Oscillatory Burst Discharges in the Reticular Thalamus and Absence Epilepsy
Neurons of the reticular thalamus (RT) display oscillatory burst discharges that are believed to be critical for thalamocortical network oscillations related to absence epilepsy. Ca²+-dependent mechanisms underlie such oscillatory discharges. However, involvement of high-voltage activated (HVA) Ca²+ channels in this process has been discounted. We examined this issue closely using mice deficien...
متن کاملImpact of Winko on absolute discharges.
In Canada, case laws have had a significant impact on the way mentally ill offenders are managed, both in the criminal justice system and in the forensic mental health system. The Supreme Court of Canada's decision with respect to Winko has set a major precedent in the application of the test of significant risk to the safety of the public in making dispositions by the Ontario Review Board and ...
