In Mice Lacking V2a Interneurons, Gait Depends on Speed of Locomotion

It is shown that spinal V2a interneurons are required for maintaining left–right alternation at high speeds, and high-speed fictive locomotion evoked by caudal spinal cord stimulation also shows synchronous left-right bursting.
Serotonin and Octopamine Produce Opposite Postures in Lobsters

Neurophysiological analyses show that these postures can be accounted for by opposing, coordinated effects of these amines on patterns of motoneuron activity recorded from the ventral nerve cord.

This work has shown clear parallels with other invertebrate and vertebrate motor systems in the crustacean stomatogastric nervous system, and these parallels are likely to have implications for the design and operation of future nervous systems in crustaceans.
Modulation of neural networks for behavior.
- R. Harris-Warrick, E. Marder
- BiologyAnnual Review of Neuroscience
- 1991
Recent work showing that anatomical networks in the nervous system provide a physical back bone upon which a large library of modulatory inputs can operate allows the networks to produce multiple variations in output under different conditions.
Dopamine modulates two potassium currents and inhibits the intrinsic firing properties of an identified motor neuron in a central pattern generator network.

The results suggest that DA hyperpolarizes and phase delays the activity of the PD neurons at least in part by modulating their intrinsic postinhibitory recovery properties.
Electrophysiological Characterization of V2a Interneurons and Their Locomotor-Related Activity in the Neonatal Mouse Spinal Cord
- Guisheng Zhong, Steven Droho, R. Harris-Warrick
- BiologyJournal of Neuroscience
- 6 January 2010
Earlier proposals that the V2a interneurons are components of the hindlimb central pattern generator, helping to organize left–right locomotor coordination in the neonatal mouse spinal cord are reinforced.
Activity-independent coregulation of IA and Ih in rhythmically active neurons.
- J. MacLean, Ying Zhang, R. Harris-Warrick
- BiologyJournal of Neurophysiology
- 30 March 2005
An activity-independent homeostatic mechanism maintains constant neuronal activity in the face of dramatic increases in IA, as observed experimentally in both shal-injected and noninjected neurons.
Distributed Effects of Dopamine Modulation in the Crustacean Pyloric Network a

- BiologyAnnals of the New York Academy of Sciences
- 1 November 1998
Using dopamine modulation of the 14‐neuron pyloric network from the crustacean stomatogastric ganglion as an example, two major mechanisms by which network output is modulated are described, emphasizing the distributed nature of modulation in motor networks.
