Comparative mapping of GABA‐immunoreactive neurons in the central nervous systems of nudibranch molluscs
The relative simplicity of certain invertebrate nervous systems, such as those of gastropod molluscs, allows behaviors to be dissected at the level of small neural circuits composed of individuallyExpand

Tension sensitivity of the heart pacemaker neurons in the isopod crustacean Ligia pallasii
SUMMARY In the crustacean neurogenic heart, the cardiac ganglion (CG) acts as a peripherally located central pattern generator (CPG) by producing rhythmic motor output that initiates the heartbeat.Expand

Spike Timing-Dependent Serotonergic Neuromodulation of Synaptic Strength Intrinsic to a Central Pattern Generator Circuit
Neuromodulation is often thought to have a static, gain-setting function in neural circuits. Here we report a counter example: the neuromodulatory effect of a serotonergic neuron is dependent on theExpand

Homology and homoplasy of swimming behaviors and neural circuits in the Nudipleura (Mollusca, Gastropoda, Opisthobranchia)
How neural circuit evolution relates to behavioral evolution is not well understood. Here the relationship between neural circuits and behavior is explored with respect to the swimming behaviors ofExpand

Different Roles for Homologous Interneurons in Species Exhibiting Similar Rhythmic Behaviors
It is often assumed that similar behaviors in related species are produced by similar neural mechanisms. To test this, we examined the neuronal basis of a simple swimming behavior in two nudibranchsExpand

Two interconnected kernels of reciprocally inhibitory interneurons underlie alternating left-right swim motor pattern generation in the mollusk Melibe leonina.
The central pattern generator (CPG) underlying the rhythmic swimming behavior of the nudibranch Melibe leonina (Mollusca, Gastropoda, Heterobranchia) has been described as a simple half-centerExpand

Identification of two cardioacceleratory neurons in the isopod crustacean, Ligia exotica and their effects on cardiac ganglion cells
Abstract We identified two pairs of cardioacceleratory (CA1, CA2) neurons in the central nervous system of the isopod Ligiaexotica and examined their effects on the cardiac ganglion (CG). CA1 neuronsExpand

Cycle period of a network oscillator is independent of membrane potential and spiking activity in individual central pattern generator neurons.
Rhythmic motor patterns are thought to arise through the cellular properties and synaptic interactions of neurons in central pattern generator (CPG) circuits. Yet, when examining the CPG underlyingExpand

Hidden synaptic differences in a neural circuit underlie differential behavioral susceptibility to a neural injury
Individuals vary in their responses to stroke and trauma, hampering predictions of outcomes. One reason might be that neural circuits contain hidden variability that becomes relevant only when thoseExpand

Artificial Synaptic Rewiring Demonstrates that Distinct Neural Circuit Configurations Underlie Homologous Behaviors
Behavioral homology is often assumed to involve similarity in underlying neuronal mechanisms. Here, we provide a counterexample where homologous behaviors are produced by neurons with differentExpand
