Neuromodulation of vertebrate locomotor control networks.
Vertebrate locomotion must be adaptable in light of changing environmental, organismal, and developmental demands. Much of the underlying flexibility in the output of central pattern generating (CPG) networks of the spinal cord and brain stem is endowed by neuromodulation. This review provides a synthesis of current knowledge on the way that various neuromodulators modify the properties of and ...
متن کاملParallel evolution of serotonergic neuromodulation underlies independent evolution of rhythmic motor behavior.
Neuromodulation can dynamically alter neuronal and synaptic properties, thereby changing the behavioral output of a neural circuit. It is therefore conceivable that natural selection might act upon neuromodulation as a mechanism for sculpting the behavioral repertoire of a species. Here we report that the presence of neuromodulation is correlated with the production of a behavior that most like...
متن کاملAge-related differences in locomotor targeting performance under structural interference.
OBJECTIVE to determine if there are age-related differences in locomotor targeting (LT) performance and step length (SL) regulatory behaviour under structural interference. METHODS forty older (n = 20, mean age = 77.9) and younger (n = 20, mean age = 25.2) participants walked 11.6 m while stepping on a target positioned at the 9.5 m point. Participants completed seven trials under each of thr...
متن کاملSerotonergic activation of locomotor behavior and posture in one-day old rats.
The purpose of this study was to determine what dose of quipazine, a serotonergic agonist, facilitates air-stepping and induces postural control and patterns of locomotion in newborn rats. Subjects in both experiments were 1-day-old rat pups. In Experiment 1, pups were restrained and tested for air-stepping in a 35-min test session. Immediately following a 5-min baseline, pups were treated with...
متن کاملSerotonergic Innervation of Cat Spinal Locomotor Neurons
Monoamines are strong modulators and/or activators of spinal locomotor networks. 21 Thus, monoaminergic fibers likely contact neurons involved in generating locomotion. The aim 22 of the present study was to investigate the serotonergic innervation of locomotor-activated 23 neurons within the thoraco-lumbar spinal cord following induction of hindlimb locomotion. This 24 was determined by immuno...
