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).

Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...

Neural Circuits
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...
