title: Temporal integration of intracellular Ca2+ signaling networks in regulating gene expression by action potentials.
abstract: Temporal aspects of intracellular calcium signaling are particularly important in activity-dependent regulation of gene expression in neurons. This review traces calcium-dependent intracellular signaling from the membrane to the nucleus in response to action-potential firing, and considers how specific genes are regulated by specific patterns of impulse firing. Modes of calcium influx, calcium-dependent protein kinases, transcription factors, individual genes, and genomic analysis are examined, with particular emphasis on the importance of temporal aspects of calcium dynamics in regulating these processes.
