Analysis of postural motoneuron activity in crayfish abdomen. I. Coordination by premotoneuron connections.

abstract：:During early development neuronal networks express slow oscillating synchronized activity. The activity can be driven by several, not necessarily mutually exclusive, mechanisms. Each mechanism might have distinctive consequences for the phenomenology, formation, or sustainment of the early activity pattern. Here we st...
