Sincronización
La sincronización es un fenómeno de sumo interés que aparece en multitud de sistemas complejos. Steven Strogatz, profesor de matemática 
aplicada de Cornell University en el libro Sync: The Emerging Science of Spontaneous Order, Hyperion, New York, 2003, describe de modo ameno para el gran público la nueva ciencia de la sincronización, en donde se examinan los modos en los que varios elementos de la naturaleza funcionan en conjunción y en armonia unos con otros. Este tipo de fenómenos ocurren en las celulas del corazón, poblaciones de neuronas que se activan de modo sincrónico, así como en los fotones o electrones que se sincronizan para producir laseres y semiconductores.

estoy interesado en la sincronizacion de las celulas del corazon y me gustaria saber donde encontrar articulos sobre este tema

Tropical fireflies, particularly in Southeast Asia, routinely synchronise their flashes among large groups, an example of biological synchronicity. In some fields, this phenomenon is explained as phase synchronization and spontaneous order. At night along river banks in the Malaysian jungles (most notably found near Kuala Selangor), fireflies («kelip-kelip» in the Malay language or Bahasa Malaysia) synchronise their light emissions precisely. Current hypotheses about the causes of this behavior involve diet, social interaction, and altitude. In the Philippines, thousands of fireflies can be seen all year round in the town of Donsol (called aninipot or totonbalagon in bicol dialect). In the United States, one of the most famous sightings of fireflies blinking in unison occurs annually near Elkmont, Tennessee in the Great Smoky Mountains during the first weeks of June. Congaree National Park in South Carolina is another host to this phenomenon.

Phase synchronization is the process by which two or more cyclic signals tend to oscillate with a repeating sequence of relative phase angles.
Phase synchronisation is usually applied to two waveforms of the same frequency with identical phase angles with each cycle. However it can be applied if there is an integer relationship of frequency, such that the cyclic signals share a repeating sequence of phase angles over consecutive cycles. These integer relationships are the so called Arnold tongues which follow from bifurcation of the circle map.
One example of phase synchronization of multiple oscillators can be seen in the behavior of Southeast Asian fireflies. At dusk, the flies begin to flash periodically with random phases and a gaussian distribution of native frequencies. As night falls, the flies, sensitive to one another’s behavior, begin to synchronize their flashing. After some time all the fireflies within a given tree (or even larger area) will begin to flash simultaneously in a burst.
