Sensory Feedback Induced by Front-Leg Stepping Entrains the Activity of Central Pattern Generators in Caudal Segments of the Stick Insect Walking System
TLDR
The data suggest that front-leg stepping in isolation would result in in- phase activity of all ipsilateral legs, and functional stepping gaits emerge because of local load sensory feedback overriding this in-phase influence. Expand
Phase Maintenance in the Pyloric Pattern of the Lobster (Panulirus interruptus) Stomatogastric Ganglion
  • S. Hooper
  • Biology, Medicine
  • Journal of Computational Neuroscience
  • 1 July 1997
TLDR
This work investigated the issue of delay changes in the well-defined, rhythmic pyloric neural network, which suggest that, in response to changes in overall cycle frequency, these constants vary so as to maintain patternphasing. Expand
A "learning society"?

  • 10 May 1996
TLDR
I began to read the editorial in the 12 April issue assuming that it was written by the president of the AAAS, and as I read, I became more and more convinced that this was not the case. Expand
The Pyloric Pattern of the Lobster (Panulirus interruptus) Stomatogastric Ganglion Comprises Two Phase-Maintaining Subsets
  • S. Hooper
  • Biology, Computer Science
  • Journal of Computational Neuroscience
  • 1 July 1997
The pyloric pattern approximately maintains phase over a three- tofivefold frequency range when the pattern is defined by the pacemakerburst beginning. However, in this reference frame certainExpand
Modulation of the lobster pyloric rhythm by the peptide proctolin

  • 1 July 1987
TLDR
A comparison of proctolin's effects on isolated neurons with those on the intact network shows that the synaptic connectivity among neurons directly affected by Proctolin and those unaffected by it shapes the network's response to proctolini. Expand
Invertebrate muscles: Thin and thick filament structure; molecular basis of contraction and its regulation, catch and asynchronous muscle
TLDR
Invertebrate actomyosin is both thin and thick filament regulated, and most invertebrate muscles are dually regulated, but the behavioral utility of dual regulation is less so. Expand
Neural Control of Unloaded Leg Posture and of Leg Swing in Stick Insect, Cockroach, and Mouse Differs from That in Larger Animals
TLDR
Size-dependent variations in whether legs have constant, gravity-independent postures, in whether swing motor neurons fire throughout the entirety of swing, and calculations of how quickly passive muscle force would slow limb movement as limb size varies suggest that these differences may be caused by scaling. Expand
A computational role for slow conductances: single-neuron models that measure duration
TLDR
It is shown that model neurons containing physiological slow conductances are 'naturally' sensitive to duration, replicate known duration-sensitive neurons and can be 'tuned' to respond to a wide range of specific durations. Expand
Follower neurons in lobster (Panulirus interruptus) pyloric network regulate pacemaker period in complementary ways.
TLDR
The data show that follower neurons in pacemaker networks can play central roles in controlling pacemaker period and suggest that in some cases specific functions can be assigned to individual network neurons. Expand
Switching of a neuron from one network to another by sensory-induced changes in membrane properties.
TLDR
Functional membership of neurons in central networks is thus not fixed, and long-lasting neuromodulatory influences, controlled at least in part by sensory inputs, can switch neurons from one network to another. Expand
