Concentric chemical waves emanating from pacemaker centers — click to create new pacemakers
Target patterns form when an oscillating pacemaker center periodically fires excitation waves into surrounding excitable tissue.
Key features:
• Faster pacemakers "annex" territory — their waves dominate over slower ones
• Waves annihilate upon collision (refractory zone prevents crossing)
• Classic BZ reaction displays: bright red/orange rings on blue background
