“…Using non-linguistic stimuli, the scalp distribution of N2 based on difference waveforms is similar to that obtained without subtractions for omitted stimuli, and distinct for auditory and visual conditions (Simson et al, 1976(Simson et al, , 1977. Another example is the identification of motor potentials through subtractions (Vaughan, Costa, Gilden, & Schimmel, 1965). There are other components, however, which always appear to overlap with other components and can not be observed without subtraction (or other procedures like PCA or simple superimposition of waveforms).…”

Event‐related potentials were studied while subjects performed physical and semantic discrimination tasks. Two negative components, NA and N2, were observed in both kinds of discriminations. The earlier component, NA, had a constant onset latency, but its peak latency varied as a function of stimulus complexity. N2 latency varied in relation to changes in the peak of NA. RT and P3 followed N2 by similar amounts of time across tasks. The NA and N2 components were interpreted as reflecting partially overlapping sequential stages of processing associated with pattern recognition and stimulus classification, respectively.

“…Scalp-recorded movement-related cortical potentials (MRCPs) start about 2 s prior to self-paced voluntary movements 19,20) and include several different components: (1) a gradual and bilaterally symmetrical negativity (Bereitschaftspotential: BP), (2) a steeper asymmetrical negativity (negative slope: NS'), (3) a small pre-motion positivity (PMP), (4) a transient small negative deflection (motor potential: MP), and (5) a large positive deflection (reafferent potential: RAP) 21,22) . The negative slow wave, including the BP and NS', are commonly referred to as the readiness potential (RP).…”

In this review, focus is given to the cognitive brain functions associated with motor learning and the control of learned motor behavior, as revealed by non-invasive studies in humans. After providing a definition of motor control and learning, the tasks adopted in previous studies are first introduced, and some important findings about motor behavior and pertinent theoretical models are described. Relying mainly on findings from the event-related potential (ERP) technique, but also from neuroimaging, this review focuses on motor learning and motor control in skilled action, with an emphasis on movement preparation and performance monitoring.

“…Here, we must also consider the MRCP, movement-related cortical potential, which is detected at the scalp 1 or 2 seconds prior to voluntary work, and reflects the progressive negative slow potential variation 1,2) . The MRCP has been divided into nine components 1,6,12) , and in athletes a reduction is known to occur in the latency of the bereitschaftspotential (BP) and negative slope (NS') within the potential 13) .…”

“…This processing sequence is complex and much of it awaits elucidation. Movement preparation in the brain is mostly done in the frontal lobe [1][2][3][4][5][6][7][8] . At this time the activity of the primary motor cortex consists of two components, one responsible for the preparation of movement and one for the execution of it 9) .…”

Abstract. [Purpose] We divided the jump action into a resting phase and a motion execution phase, so that we could shed light on each phase's relationship with the whole body reaction time in jump. [Subjects and Methods] Whole body reaction of young subjects in their late teens was recorded with a high-speed video camera to identify moving reaction time.[Results] The results revealed a high correlation between jumping reaction time and the light stimulus to movement initiation, and the movement initiation to feet-off. Individual variation existed in neural processing velocity of movement preparation and execution, and the processing velocity was shown to reflect the whole body reaction time in jumping.[Conclusion] The outcome suggests that improvement of body performance can be achieved not only by muscle stretch and elastic energy recruitment training but also by faster neural processing.
