2015, Current Opinion in NeurobiologyCitation Excerpt :The changes in muscle synergy activation patterns would be produced by appropriate changes in the phase and magnitude of populations of PTNS, as illustrated in Figure 3c. We have suggested that the activity in the cortical neurones would act through spinal interneuronal networks that form part of, or are influenced by, the central pattern generator (CPG) modules that assure both the pattern and the rhythmicity of locomotion (Figure 3d) [30•,31,32]. This would ensure that the changes in muscle activity are integrated into the gait cycle.
Leg automaticity is stronger than arm automaticity during simultaneous arm and leg cycling
2014, Neuroscience LettersCitation Excerpt :Indeed, rhythmic movement motor patterns are easily modulated by altering visual stimuli [23]. When avoiding an obstacle, limb movement patterns are promptly selected based on visual information about the obstacle [7,27]. If increased arm cadence variability is attributable to altered visual information when the participants adjusted leg cadence to match the value on the screen, the same outcome would be expected for preferred leg cadence when the participants adjusted arm cadence to predetermined values.

2007, Progress in Brain ResearchCitation Excerpt :The fourth level comprises the CPG rhythm generator or oscillator, whose activity is adjusted or reset by sensory input, as well as by input descending from the fifth and highest level, which comprises the brainstem (Shik et al., 1966; Takakusaki et al., 2004), cerebellum (Arshavsky et al., 1986), and motor cortex (Beloozerova and Sirota, 1993; Drew, 1993; Widajewicz et al., 1994). These higher centers integrate a wide variety of inputs, including motivational (Jordan, 1998), exteroceptive (Drew, 1991; Rossignol, 1996; Patla et al., 1999), and proprioceptive inputs, to define state and intention and to predict upcoming motor requirements. There have been several excellent reviews of the above mechanisms over the last few years (Pearson, 2004; Frigon and Rossignol, 2006; Rossignol et al., 2006).
