  • Title: Mutual coupling among insect neurosecretory cells with an ultradian firing rhythm.
    Author: Ichikawa T.
    Journal: Neurosci Lett; 2001 Feb 16; 299(1-2):73-6. PubMed ID: 11166941.
    Abstract:
    Firing correlations were examined among four pairs of cerebral neurosecretory cells with an ultradian bursting rhythm in the pupal silkmoth Bombyx mori. Cross-correlation analyses of spiking activities between pairs of simultaneously active cells usually revealed a significant correlation of firings: 20-50% of spikes of a cell fired within 0.2 s before or after the other cell's spikes fired. The mutual, excitatory communication among neurosecretory cells make the set of cells a weakly coupled multi-oscillator system that may generates a pulsatile release pattern of their product, an insulin-related neuropeptide (bombyxin).
