An individual element of this activity is the slow wave itself (Fig. 1a ), which can also ... Webbstopped conducting (46%), in contrast to slow waves that never did. Peristaltic waves propagated at a lower velocity than the slow waves (0.98 0.25 and 1.29 0.28 cm/s, respectively; P 0.001; n 24) and in a direction indepen-dent of the preceding slow wave direction (64% in the same direction, 46% in the opposite direction).

Webb1 jan. 2014 · Definition. Slow oscillations are the coordinated activity of large populations of neurons consisting of an alternation of active periods (Up states) and silent periods (Down states). These oscillations occur with a slow frequency (≤ 1 Hz) in the corticothalamocortical network during slow-wave sleep and deep anesthesia, and they … Webbwaves (e.g., Tu & Marsch 1995; and references therein). The solar wind plasma is well described by the ideal MHD equations (Hollweg 1975). In this regime, three linear MHD waves exist, namely, Alfvén, slow, and fast waves. Alfvén waves are incompressible MHD waves characterized by high (anti)correlations between velocity and magnetic field ...
