Genetic Analysis of Drosophila Stomatogastric Nervous System
… formation are still under debate.The Drosophila stomatogastric nervous system (SNS) is the invertebrate equivalent of the ENS and with the fly's powerful genetics offers the opportunity to shed light on the molecular and cellular mechanisms functioning in ENS development. Ret gene expression is …

The control of frequency of a conditional oscillator simultaneously subjected to multiple oscillatory inputs
… of such is the gastric mill network of the stomatogastric ganglion of the crab Cancer borealis which requires modulatory input from outside the stomatogastric ganglion and fast input from the pyloric network of the animal in order to become active. This dissertation studies how the frequency …

Translation and transcription are required for endogenous bursting after long term removal of neuromodulators
… The pyloric network of the Cancer borealis stomatogastric ganglion (STG), a rhythmic motor pattern-generating network, requires modulatory inputs to generate this activity. When neuromodulatory inputs are removed, the pyloric network falls silent. However, patterned pyloric activity recovers …

A modeling study of the history-dependence of conduction delay in unmyelinated axons
… (PD) neuron unmyel i nated motor axon in the stomatogastric nervous system, shows significant variability with ongoing bursting or Poisson stimulation. When the axon is stimulated, the mean value (Dmean) and coefficient variation of conduction delay (CV-D) slowly increase with time (slow …

Biophysical mechanisms of frequency-dependence and its neuromodulation in neurons in oscillatory networks
In response to oscillatory input, many isolated neurons exhibit a preferred frequency response in their voltage amplitude and phase shift. Membrane potential resonance (MPR), a maximum amplitude in a neuron’s input impedance at a non-zero frequency, captures the essential subthreshold properties of …

A mathematical and computational exploration of the effect of the A-current in determining the activity phase of follower neurons
Bursting oscillations are prevalent in neurons of central pattern generators (CPGs) that produce rhythmic motor activity, and the activity phase plays an important role in determining the normal or dysfunctional network output. The activity phase is the delay time-with respect to some reference …

Modeling projection neuron and neuromodulatory effects on a rhythmic neuronal network
Projection neurons shape the activity of many neural networks. In particular, neuromodulatory substances, which are often released by projection neurons, alter the cellular and/or synaptic properties within a target network. However, neural networks in turn influence projection neuron input via …
