WebbIn the small intestines, the major task of the slow wave is to induce mechanical movements in the intestinal wall by generating local calcium spikes. High resolution electrical mapping reveals fundamental differences in propagation between slow waves and calcium spikes. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/basics/slowwaves.html
WebbHowever, the clinical significance of parameters such as %normal and % slow wave coupling (%SWC) obtained in the multichannel electrogastrography (M-EGG) are few. Attempts were made to examine the ... WebbNMDA spikes result in plateau potentials with large dendritic depolarizations (around 30 mV). These spikes are less attenuated en route to the soma than subthreshold EPSPs …
Webb14 maj 2015 · Many neurons have slow intrinsic membrane currents that can modulate fast spiking activity. Typically, the currents build up during continuous spiking, hyperpolarize the cell and result in the termination of the spike train. While the cell is quiescent, the currents slowly decay, the cell recovers, and it is ready to fire another burst.

WebbA blinded reviewer analyzed the EEG offline and identified spike-wave discharges (SWD) using criteria established for the analysis of rat models of absence epilepsy (Akman et al., 2010). Briefly SWD were defined as trains (>1s) of rhythmic biphasic spikes, with a voltage at least two-fold higher than baseline and that were associated with aftergoing slow … chinese lower claptonWebb26 maj 2016 · Top-down cortical information flow in NREM sleep is thus required for perceptual memory consolidation. Non–rapid eye movement (NREM) sleep is essential for memory consolidation of an animal’s awake motor ( 1) and sensory ( 2) learning experiences.
