here is an experimental record (mpeg movie, 236 k) of the dynamics in the
system. Arrows point at the regions of interest: rotating spiral wave (chemical
vortex), and zone of chaotic oscillations.
Computer
simulations of the BZ reaction. Rotating vortices in the form of Archimedian
spiral (left) and logarithmic spiral (right). ?Holes? in the centers -
the cores of vortices. The dynamics is described in refs. [17,20,24]
of my reference list .
A scheme of a cardiac cell, namely, a SAN cell. To properly simulate such a cell, we need to account for both membrane currents and balance of intracellular ions and the function of Sarcoplasmic Reticulum. My current interest in this is the effect of ACh on a cardiac myocite.
Computer simulations of the heart. A pulse is initiated at the bottom
of the right ventricular. Only the front of the propagating pulse is shown.
Several more animations of heart dynamics with LR kinetics are here
N.B. above are animated pictures. If you see just static
figs, please, upgrade your web browser.
Three balls are started to move with equal velocities v from the same position
