previous studies, and the effect of discontinuous short-term fine MI on the fine motor skills was not clear. The effects of fine finger MI training alternated with no-MI, which was performed within 1 hr, on fine motor execution were investigated in this study. The EEG, and the event-related potentials

In event-related potential (ERP) studies, badminton players, relative to nonathletic controls, have been found to exhibit enlarged amplitudes of C1 and P3 components along with more accurate

Motor learning can be monitored by observing the development of neural correlates of error processing. Among these neural correlates, the error- and feedback-related negativity (Ne/ERN and FRN) represent error processing mechanisms. While the Ne/ERN is more related to error prediction, the FRN is found after an error is manifested. The questions the current study strives to answer are: What information is needed by the system to make error predictions and how is this represented by the Ne/ERN and FRN in a complex motor task? We reduced the information and increased the difficulty level for the prediction in a semivirtual throwing task and found no Ne/ERN but a large FRN when the action result was finally observed (hitting or missing a target). We assume that uncertainty for error prediction was too high (either due to insufficient information or due to lacking prerequisites for prediction), such that error processing had to be mainly based on feedback. The finding is in line with the reinforcement theory of learning, after which Ne/ERN and FRN should behave complementary.

Psychophysiological responses of two rival sport fan groups were assessed within the context of Lang’s biphasic theory of emotion. Twenty-four participants, placed in two groups based on their identification with local sport teams, viewed 6 pictures from 6 categories: team-relevant pleasant sport, team-irrelevant sport, team-relevant unpleasant sport, erotica, household objects, and mutilation. Fans rated appetitive sport pictures higher in pleasure and arousal compared to aversive sport pictures. Physiological measures (startle probe-P3, the startle eye-blink reflex, slow cortical potentials to picture onset, and skin conductance) differentiated both appetitive and aversive team-relevant categories from team-irrelevant pictures, and increased orbicularis oculi EMG was found only for team-relevant appetitive pictures. These results suggest there are differences between rival sport fans in response to the same pictorial stimuli, and further suggest that fans provide an ideal population in which to measure motivation toward appetitive stimuli.

The study aimed to investigate the effects of regular physical activity on visuospatial cognition in elderly adults, and to further understand the potential neural mechanisms underpinning such effects. We assessed 24 physically active elderly adults and 24 sedentary counterparts using behavioral and neuroelectric measures during a visuospatial cognitive task with different levels of cognitive load. The results showed that the active group had higher behavioral accuracy along with greater P3 amplitudes, regardless of the level of cognitive load. Moreover, the correlation results revealed that physical activity levels were positively associated with accuracy performance in both conditions, while being correlated with frontal P3 amplitudes in the high cognitively demanding condition. However, no significant effects were observed in terms of P3 latency and contingent negative variation. These findings suggest that regular physical activity might be part of an effective lifestyle to attenuate the trajectory of age-related cognitive declines, thus increasing the likelihood of individuals becoming high-functioning older adults.

Alzheimer’s disease (AD) is a neurodegenerative disorder, characterized by a gradual decline in numerous cognitive processes and altered cortical activity. 1 Indeed, the development of AD is usually accompanied by systematic changes in various cortical event-related potentials. In this population

This study investigated the effect of hand movements on behavioral and electro-physiological parameters of saccade preparation. While event-related potentials were recorded in 17 subjects, they performed saccades to a visual target either together with a hand movement in the same direction, a hand movement in the opposite direction, a hand movement to a third, independent direction, or without any accompanying hand movements. Saccade latencies increased with any kind of accompanying hand movement. Both saccade and manual latencies were largest when both movements aimed at opposite directions. In contrast, saccade-related potentials indicating preparatory activity were mainly affected by hand movements in the same direction. The data suggest that concomitant hand movements interfere with saccade preparation, particularly when the two movements involve motor preparations that access the same visual stimulus. This indicates that saccade preparation is continually informed about hand movement preparation.

We used the event-related potential (ERP) methodology to examine differences in neural processing between visually and memory-guided reaches. Consistent with previous findings (e.g., Westwood, Heath, & Roy, 2003), memory-guided reaches undershot veridical target location to a greater extent than their visually guided counterparts. Analysis of the ERP data revealed that memory-guided reaches were associated with reduced potentials over medial-frontal cortex at target presentation and following movement onset. Further, we found that the amplitudes of the potentials over medial-frontal cortex for visually and memory-guided reaches were significantly correlated with the peak accelerations and decelerations of the reaching movements. Our results suggest that memory-guided reaches are mediated by a motor plan that is generated while a target is visible, and then stored in memory until needed—a result counter to recent behavioral theories asserting that memory-guided reaches are planned just before movement onset via a stored, sensory-based target representation.

The purpose of the current study was to examine the relationship between motor ability and response inhibition using behavioral and electrophysiological indices in children with ADHD. A total of 32 participants were recruited and underwent a motor ability assessment by administering the Basic Motor Ability Test-Revised (BMAT) as well as the Go/No-Go task and event-related potential (ERP) measurements at the same time. The results indicated that the BMAT scores were positively associated with the behavioral and ERP measures. Specifically, the BMAT average score was associated with a faster reaction time and higher accuracy, whereas higher BMAT subset scores predicted a shorter P3 latency in the Go condition. Although the association between the BMAT average score and the No-Go accuracy was limited, higher BMAT average and subset scores predicted a shorter N2 and P3 latency and a larger P3 amplitude in the No-Go condition. These findings suggest that motor abilities may play roles that benefit the cognitive performance of ADHD children.
