Small networks in island can generate synchronized activity

A small network grown on an island, containing eight cells (red). Activity of one of these neurons was recorded with patch clamp electrophysiological methods and was stained with biocytin (green) to allow detection of all the processes that the neuron sends out. These processes grow only within the boundary of the island, and the method allows detection of activity of all the neurons participating in the activity of the network. This allows analysis of the minimal network properties that can produce synchronous activity in controlled conditions. (For further details, see 290)
