“…Note that patient ED's vocal responses to unilateral tactile stimulation of the left hand were, analogously, slower than for the right hand, to an extent that exceeds normal callosal transmission times [28]; see Table 2. Moreover, by contrast, the age-matched controls responded somewhat faster to left-hand stimuli than to stimulation of the right hand in the identical task.…”

“…There is also evidence that in humans such bilateral representations could be linked to an asymmetric velocity of transfer towards the specialized hemisphere ( Nowicka et al 1996). Marzi et al (1991) found that visuomotor information was transferred faster from the right to left hemisphere and then vice versa (Nalcaci et al 1999). Asymmetries for a certain brain function could therefore go along with asymmetries of the respective representation.…”

Brain asymmetries are a widespread phenomenon among vertebrates and show a common behavioural pattern. The right hemisphere mediates more emotional and instinctive reactions, while the left hemisphere deals with elaborated experience-based behaviours. In order to achieve a lateralized behaviour, each hemisphere needs different information and therefore different representations of the world. However, how these representations are accomplished within the brain is still unknown. Based on the pigeon's visual system, we present experimental evidence that lateralized behaviour is the result of the interaction between the subtelencephalic ascending input directing more bilateral visual information towards the left hemisphere and the asymmetrically organized descending telencephalic influence on the tecto-tectal balance. Both the bilateral representation and the forebrain-modulated information processing might explain the left hemispheric dominance for complex learning and discrimination tasks.

“…Among healthy controls, most estimates of the IHTT based on unimanual responses to simple visual stimuli range between 2.0 and 6.0 msec (Bashore, 1981;Marzi et al, 1991). In support of the interpretation that the CUD reflects callosal transfer time, the CUD has been shown to be markedly increased among individuals with congenital or acquired absence of the corpus callosum (e.g., Forster & Corballis, 1998;Zaidel & Iacoboni, 2003;Berlucchi, Aglioti, Marzi, & Tassinari, 1995;Clarke & Zaidel, 1989;Milner et al, 1985;Lassonde, Sauerwein, & Lepore, 2003).…”

Several lines of evidence suggest the possibility of abnormal interhemispheric communication in psychopathy, but there have been few direct empirical studies. To address this gap in the literature, we examined one important aspect of interhemispheric communication, the efficiency with which information is transferred across the corpus callosum. Using Poffenberger's (1912) paradigm for estimating interhemispheric transfer time (IHTT) from simple motor responses to lateralized stimuli, we found a substantially prolonged IHTT among psychopathic criminals relative to nonpsychopathic criminals. This prolonged IHTT was somewhat more pronounced when participants were using their right hand to respond. This study provides initial behavioral evidence of slowed interhemispheric transfer in psychopathy.
