Precise Temperature Compensation of Phase in a Rhythmic Motor Pattern
Most animal species are cold-blooded, and their neuronal circuits must maintain function despite environmental temperature fluctuations. The central pattern generating circuits that produce rhythmic motor patterns depend on the orderly activation of circuit neurons. We describe the effects of temperature on the pyloric rhythm of the stomatogastric ganglion of the crab, Cancer borealis. The pylo...
متن کاملPhase maintenance in a rhythmic motor pattern during temperature changes in vivo.
Central-pattern-generating neural circuits function reliably throughout an animal's life, despite constant molecular turnover and environmental perturbations. Fluctuations in temperature pose a problem to the nervous systems of poikilotherms because their body temperature follows the ambient temperature, thus affecting the temperature-dependent dynamics of various subcellular components that co...
متن کاملPrinciples of rhythmic motor pattern generation.
Rhythmic movements are produced by central pattern-generating networks whose output is shaped by sensory and neuromodulatory inputs to allow the animal to adapt its movements to changing needs. This review discusses cellular, circuit, and computational analyses of the mechanisms underlying the generation of rhythmic movements in both invertebrate and vertebrate nervous systems. Attention is pai...
متن کاملthe effect of a rhythmic motor program on perceptual–motor abilities of educable mentally retarded children
the aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (pma) and the intelligence quotient (iq) of educable mentally retarded (emr) children. the sample consisted of 24 emr girls (mean age = 11.98+1.43 years and iq = 70.58+ 9.95). then, they were matched and assigned to two groups of intervention and control according to their iq and pma ...
متن کاملPhase-dependent respiratory-motor interactions in reaction time tasks during rhythmic voluntary breathing.
The study investigated squeezing reaction time (RT) in response to a visual cue during rhythmic voluntary breathing at 0.6 Hz paced by a metronome, breath holding, or at rest in 13 healthy subjects. Rhythmic voluntary breathing slowed down RT, only in the expiratory phase with accompanied changes in the length of respiratory phases, while breath-holding reduced RT. The prolonged RT during volun...
