“…The left one, on the contrary, is responsible for perception of little details of the picture [16][17][18]. The data are agreed with complementary principle, when the left hemisphere outgoes the right one in perception of information, and the right one, getting information independently and through the left one, is a leading one as to the stimuli processing [19].…”

The article considers the correlative analysis of amplitude-temporal characteristics of evoked potentials of brain cortex in sportsmen of playing kinds of sport and athletes at perception and processing of significant information “What” and “Where” in the brain cortex. The method of electroencephalography (Р300 methodology) was used to study the evoked potentials of the brain cortex. The statistical processing of data was realized using the statistical package MedStat. Kendall coefficient of correlation was used depending on data distribution, different from the normal values distribution. In the result of research there were revealed the high interconnections of latency of later components in sportsmen of both groups of examined persons at observation of significant stimuli “What” and “Where”. There was revealed the intensification of correlations of latency in frontal, central and temporal parts of the brain cortex. The correlations of amplitude of late components of biopotentials of the brain cortex were characterized with mean coefficients of interconnection mainly in sagittal central frontal and also parietal parts of cortex.

“…For example, performance in sports is improved by training, which develops relevant sensory–motor skills, and these improved skills are reflected in neuroplastic alterations in relevant cortical regions. Studies on athletes using somatosensory evoked potentials (SEPs) and event-related potentials (ERPs) following tactile stimulation suggest that specific training can modify the excitability of the somatosensory cortex and neuronal circuits of the brain related to specific cognitive processes[ 1 , 2 , 3 , 4 ].…”

Skill-Specific Changes in Somatosensory Nogo Potentials in Baseball Players

Athletic training is known to induce neuroplastic alterations in specific somatosensory circuits, which are reflected by changes in somatosensory evoked potentials and event-related potentials. The aim of this study was to clarify whether specific athletic training also affects somatosensory Nogo potentials related to the inhibition of movements. The Nogo potentials were recorded at nine cortical electrode positions (Fz, Cz, Pz, F3, F4, C3, C4, P3 and P4) in 12 baseball players (baseball group) and in 12 athletes in sports, such as track and field events and swimming, that do not require response inhibition, such as batting for training or performance (sports group). The Nogo potentials and Go/Nogo reaction times (Go/Nogo RTs) were measured under a somatosensory Go/Nogo paradigm in which subjects were instructed to rapidly push a button in response to stimulus presentation. The Nogo potentials were obtained by subtracting the Go trial from the Nogo trial. The peak Nogo-N2 was significantly shorter in the baseball group than that in the sports group. In addition, the amplitude of Nogo-N2 in the frontal area was significantly larger in the baseball group than that in the sports group. There was a significant positive correlation between the latency of Nogo-N2 and Go/Nogo RT. Moreover, there were significant correlations between the Go/Nogo RT and both the amplitude of Nogo-N2 and Nogo-P3 (i.e., amplitude of the Nogo-potentials increases with shorter RT). Specific athletic training regimens may induce neuroplastic alterations in sensorimotor inhibitory processes.

“…In the last years, several EEG studies exploring the "neural efficiency" hypothesis in elite athletes have shown conflicting results (Fattapposta et al, 1996;Konttinen et al, 1999;Haufler et al, 2000;Janelle et al, 2000;Loze et al, 2001;Bulut et al, 2003;Hung et al, 2004;Iwadate et al, 2005;Ozmerdivenli et al, 2005;Endo et al, 2006;Di Russo et al, 2005Murakami et al, 2008;Nakamoto and Mori, 2008;Del Percio et al, 2008, 2009bNakata et al, 2010;. Some previous studies are in line with "neural efficiency" hypothesis, showing more selective cortical activation in elite athletes than in non-athletes.…”

“…Compared with pre-elite shooters, elite shooters were characterized by an increase of frontal slow potentials during motor preparation for rifle shooting (Konttinen et al, 1999). Furthermore, the amplitude of somatosensory evoked potentials and highfrequency oscillations were higher in football, racquetball and volleyball players than in non-athletes (Bulut et al, 2003;Murakami et al, 2008). Finally, expert golfers were characterized by stronger alpha ERD in successful than unsuccessful putt .…”
