Regional specification of threshold sensitivity and response time in CBA/CaJ mouse spiral ganglion neurons.

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...
