“…As expected from previous studies Brown & Jeeves, 1993;Brown et al, 1994;Larson & Brown, 1997), the non-musicians showed faster IHTT from the right to the left hemisphere than from left-to-right. In contrast, the musicians showed no directional advantage, indicating the speed of transfer for visual information across the corpus callosum was more equilateral in this group.…”

“…Studies of IHTT using reaction time and ERP measures have consistently indicated faster transfer from the right to the left hemisphere than from left to right in neurologically healthy adults Barnett, Corballis, & Kirk, 2005;Brown & Jeeves, 1993;Brown, Larson, & Jeeves, 1994;Larson & Brown, 1997;Marzi, Bisiacchi, & Nicoletti, 1991). This asymmetry is generally found for both verbal and non-verbal tasks (Brown & Jeeves, 1993;Brown et al, 1994; but also see Nowicka, Grabowska, & Fersten, 1996), suggesting that it is unrelated to which hemisphere is dominant for any given task.…”

Miller (1996) has proposed that the right hemisphere is specialized for fast, efficient neural transmission resulting in superiority over the left hemisphere for instantaneous processing of spatial patterns.…”

Previous behavioural research has shown that spatial attention is bilaterally represented in musicians, possibly reflecting more equal neural development between the hemispheres. We investigated this theory electrophysiologically with another measure that has shown asymmetry, interhemispheric transfer time (IHTT). Sixteen right-handed musicians and 16 matched non-musicians responded to stimuli presented to the left and right visual fields while 128-channel EEG was recorded. IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. Non-musicians showed significantly faster IHTT in the right-to-left direction than in the left-to-right direction and a shorter N1 latency in the left than in the right hemisphere. In contrast, the musician group showed no directional difference between hemispheres in IHTT, and no hemispheric difference in latency. These results indicate that musicians have more bilateral neural connectivity than non-musicians, reflected in an unusual lack of asymmetry. It is suggested that plastic developmental changes caused by extended musical training in childhood result in equally efficient connections to both hemispheres.

Others, applying a case-study approach to the analysis of electrophysiological data, report how visuo-motor routing varies both between individuals and also as a function of reaction time (Saron et al 2003a, b).…”

Whether different brain networks are involved in generating unimanual responses to a simple visual stimulus presented in the ipsilateral versus contralateral hemifield remains a controversial issue. Visuo-motor routing was investigated with event-related functional magnetic resonance imaging (fMRI) using the Poffenberger reaction time task. A 2 hemifield · 2 response hand design generated the ''crossed'' and ''uncrossed'' conditions, describing the spatial relation between these factors. Both conditions, with responses executed by the left or right hand, showed a similar spatial pattern of activated areas, including striate and extrastriate areas bilaterally, SMA, and M1 contralateral to the responding hand. These results demonstrated that visual information is processed bilaterally in striate and extrastriate visual areas, even in the ''uncrossed'' condition. Additional analyses based on sorting data according to subjects' reaction times revealed differential crossed versus uncrossed activity only for the slowest trials, with response strength in infero-temporal cortices significantly correlating with crossed-uncrossed differences (CUD) in reaction times. Collectively, the data favor a parallel, distributed model of brain activation. The presence of interhemispheric interactions and its consequent bilateral activity is not determined by the crossed anatomic projections of the primary visual and motor pathways. Distinct visuo-motor networks need not be engaged to mediate behavioral responses for the crossed visual field/ response hand condition. While anatomical connectivity heavily influences the spatial pattern of activated visuomotor pathways, behavioral and functional parameters appear to also affect the strength and dynamics of responses within these pathways.

“…Previous work employing visual-evoked potentials to measure IHTT, revealed a directional asymmetry in conduction velocities between hemispheres (e.g. Barnett, Corballis, & Kirk, 2005;Brown, Larson, & Jeeves, 1994;Iwabuchi & Kirk, 2009;Moes, Brown, & Minnema, 2007;Nowicka & Fersten, 2001;Patston, Kirk, Rolfe, Corballis, & Tippett, 2007;Rolfe, Kirk, & Waldie, 2007;Saron & Davidson, 1989; see also Marzi, 2010, andTacikowski, 2011, for reviews). The transfer of neural information from the right hemisphere to the left is faster than transfer from the left hemisphere to the right.…”
