Neurons Controlling Aplysia Feeding Inhibit Themselves by Continuous NO Production
BACKGROUND Neural activity can be affected by nitric oxide (NO) produced by spiking neurons. Can neural activity also be affected by NO produced in neurons in the absence of spiking? METHODOLOGY/PRINCIPAL FINDINGS Applying an NO scavenger to quiescent Aplysia buccal ganglia initiated fictive feeding, indicating that NO production at rest inhibits feeding. The inhibition is in part via effects...
متن کاملPeptidergic modulation of neuronal circuitry controlling feeding in Aplysia.
We examined the effects of 3 neuropeptides and the bioactive amine 5-HT on identified motoneurons (B15 and B16) and interneurons (B4, B5) involved in the control of feeding behavior in Aplysia californica. The application of egg-laying hormone (ELH), small cardioactive peptide b (SCPb), and 5-HT elicits distinct patterns of synaptically induced bursting in the neurons, while PheMetArgPheamide (...
متن کاملDiverse synaptic connections between peptidergic radula mechanoafferent neurons and neurons in the feeding system of Aplysia.
The buccal ganglion of Aplysia contains a heterogeneous population of peptidergic, radula mechanoafferent (RM) neurons. To investigate their function, two of the larger RM cells (B21, B22) were identified by morphological and electrophysiological criteria. Both are low-threshold, rapidly adapting, mechanoafferent neurons that responded to touch of the radula, the structure that grasps food duri...
متن کاملAllatostatin-A neurons inhibit feeding behavior in adult Drosophila.
How the brain translates changes in internal metabolic state or perceived food quality into alterations in feeding behavior remains poorly understood. Studies in Drosophila larvae have yielded information about neuropeptides and circuits that promote feeding, but a peptidergic neuron subset whose activation inhibits feeding in adult flies, without promoting metabolic changes that mimic the stat...
متن کاملMesoprefrontal Dopamine Neurons Distinguish Themselves
By distinguishing groups of dopamine neurons that differ in their projection patterns and intrinsic properties, Lammel and colleagues report in this issue of Neuron that mesocorticolimbic dopamine neurons of the ventral tegmental area (VTA) form a distinct subclass of dopamine cells.
