title: Differential firing patterns of the peptide-containing cholinergic motor neurons B15 and B16 during feeding behavior in Aplysia.
abstract: During egestive responses neuron B16 fires at 20 Hz, while neuron B15 is not active. During ingestive responses B16 fires for 0.5-1.0 s at 15-20 Hz, then B15 and B16 fire together, with B15 firing at 7.5-12 Hz. The duration of activity during ingestive responses depends on consumption of food: when food is not consumed, bursts are shorter (e.g. 2 vs 4 s). This study establishes a basis for investigating the role of peripheral neuromodulation under physiologically relevant conditions.
