Flexibility of motor pattern generation across stimulation conditions by the neonatal rat spinal cord.
Previous studies have demonstrated that "locomotor-like" rhythmic patterns can be evoked in the isolated neonatal rat spinal cord by several means, including pharmacological neuromodulation and electrical stimulation of various pathways. Recent studies have used stimulation of afferent pathways to evoke rhythmic patterns, relying on synaptic activation of interneuronal systems rather than globa...
متن کاملGastric and pyloric motor pattern control by a modulatory projection neuron in the intact crab Cancer pagurus.
Neuronal release of modulatory substances provides motor pattern generating circuits with a high degree of flexibility. In vitro studies have characterized the actions of modulatory projection neurons in great detail in the stomatogastric nervous system, a model system for neuromodulatory influences on central pattern generators. Less is known about the activities and actions of modulatory neur...

Introduction: In this study we compared transcranial magnetic stimulation (TMS) elicited motor evoked potentials (MEPs) in a postural (bilateral low back extension: BLBE) and a respiratory (forced expiration during breath holding: FEBH) task.Methods: Using TMS of the left motor cortex, simultaneous patterns of corticospinal facilitation of the contralateral erector spinae (ES) and rectus abdomi...
متن کاملFunctional Principles of Pattern Generation for Walking Movements of Stick Insect Forelegs: the Role of the Femoral Chordotonal Organ Afferences
A rampwise stretch of the femoral chordotonal organ is known often to elicit a response in the active decerebrate stick insect that is termed an 'active reaction', and which can be considered to represent part of the step cycle. During the first part of the response, the flexor motor neurones are excited and the excitatory extensor motor neurones are inhibited, forming a positive feedback loop....
متن کاملThe effective of Vestibular stimulation on Improve motor skills in children educable mental retardation with developmental coordination disorder
Background and Aim: Children need to have appropriate sensory stimulation, sensory stimulation improve motor skills and competence for the children to school. Such as of these stimulations is vestibular stimulation. Many of the educable mentally disability child are the poor motor coordination and balance that some of these children, who are known as developmental coordination disorder (DCD). T...
