Hormonal modulation of two coordinated rhythmic motor patterns.
Neuromodulation is well known to provide plasticity in pattern generating circuits, but few details are available concerning modulation of motor pattern coordination. We are using the crustacean stomatogastric nervous system to examine how co-expressed rhythms are modulated to regulate frequency and maintain coordination. The system produces two related motor patterns, the gastric mill rhythm t...
متن کاملModulation of rhythmic motor activity by pyrokinin peptides.
Pyrokinin (PK) peptides localize to the central and peripheral nervous systems of arthropods, but their actions in the CNS have yet to be studied in any species. Here, we identify PK peptide family members in the crab Cancer borealis and characterize their actions on the gastric mill (chewing) and pyloric (filtering) motor circuits in the stomatogastric ganglion (STG). We identified PK-like imm...
متن کاملRunning Head: FLUCTUATIONS OF MOTOR EXCITABILITY 1 Dynamics of Motor System Excitability during Auditory Anticipation
The ability to anticipate complex sounds, like words in speech or the beat in music, is an important aspect of human perception. However, the changes of excitability in the motor system during auditory anticipation have not been characterized. Here, we applied singlepulse Transcranial Magnetic Stimulation (TMS) to the primary motor cortex to elicit motor evoked potentials (MEPs) from the first ...
متن کاملModulation of Motor Excitability by Metricality of Tone Sequences
When listening to music, humans tend to synchronize their movements with the perceived beat (e.g., foot-tapping). Brain areas associated with motor function have been closely linked to the perception of beat and rhythm, but the mechanism of this temporal auditory–motor coupling is not fully understood. To investigate how auditory rhythms affect movement, we applied single-pulse transcranial mag...
متن کاملThe Modulation of Corticospinal Excitability during Motor Imagery of Actions with Objects
We investigated whether corticospinal excitability during motor imagery of actions (the power or the pincer grip) with objects was influenced by actually touching objects (tactile input) and by the congruency of posture with the imagined action (proprioceptive input). Corticospinal excitability was assessed by monitoring motor evoked potentials (MEPs) in the first dorsal interosseous following ...
