“…In nonmatch color trials, subjects need to disengage their attention from the invalidly cued color to correctly process the color of the Stroop stimulus. Both disengagement of attention and chromatic processes are associated with right-hemisphere functions (Blumstein & Cooper, 1974; Christman, 2001; Hartje, Willmes, & Weniger, 1985; Posner, 1980) and may be responsible for the LVF advantage in nonmatch trials observed in controls. Moreover, the fact that the right hemisphere is relatively nonverbal may have reduced possible interference from target word itself (Weekes & Zaidel, 1996).…”

To investigate the role of interhemispheric attentional processes, 25 alcoholic and 28 control subjects were tested with a Stroop match-to-sample task and callosal areas were measured with magnetic resonance imaging. Stroop color-word stimuli were presented to the left or right visual field (VF) and were preceded by a color cue that did or did not match the word's color. For matching colors, both groups showed a right VF advantage; for nonmatching colors, controls showed a left VF advantage, whereas alcoholic subjects showed no VF advantage. For nonmatch trials, VF advantage correlated with callosal splenium area in controls but not alcoholic subjects, supporting the position that information presented to the nonpreferred hemisphere is transmitted via the splenium to the hemisphere specialized for efficient processing. The authors speculate that alcoholism-associated callosal thinning disrupts this processing route.

“…We speculated that controls were more successful than alcoholics in disengaging their attention from the invalidly cued color to correctly process the color of the Stroop stimulus in nonmatch color trials. Subsequent disengagement and shift of attention away from the invalidly cued color to the correct target color of the Stroop stimulus is associated with right-hemisphere functions (Blumstein and Cooper 1974; Christman 2001; Hartje et al 1985; Posner 1980) and may be responsible for the left visual field advantage in nonmatch trials observed in healthy controls. This left visual field advantage in nonmatch trials was correlated with a larger callosal splenium area in controls but not alcoholics indicating that information presented to the non-preferred hemisphere is transmitted via the splenium to the hemisphere that is specialized for efficient processing.…”

Contribution of Callosal Connections to the Interhemispheric Integration of Visuomotor and Cognitive Processes

In recent years, cognitive neuroscience has been concerned with the role of the corpus callosum and interhemispheric communication for lower-level processes and higher-order cognitive functions. There is empirical evidence that not only callosal disconnection but also subtle degradation of the corpus callosum can influence the transfer of information and integration between the hemispheres. The reviewed studies on patients with callosal degradation with and without disconnection indicate a dissociation of callosal functions: while anterior callosal regions were associated with interhemispheric inhibition in situations of semantic (Stroop) and visuospatial (hierarchical letters) competition, posterior callosal areas were associated with interhemispheric facilitation from redundant information at visuomotor and cognitive levels. Together, the reviewed research on selective cognitive functions provides evidence that the corpus callosum contributes to the integration of perception and action within a subcortico-cortical network promoting a unified experience of the way we perceive the visual world and prepare our actions.

The prosodic quality of speech comprises intonation, accent pattern, and rhythm. Among others, these dimensions contribute to the linguistic structure of an utterance and subserve emotional behaviour. Both cortical and subcortical dysfunctions can give rise to impaired speech prosody. The present paper reviews the clinical and linguistic features of the various dys- and aprosodic syndromes as well as their neuroanatomic substrates. 1. Sporadically, lesions of the left hemisphere present with dysprosody in terms of a "foreign accent". In most instances this syndrome seems to be due to apraxia of speech. 2. Some authors consider dysprosodic speech a characteristic feature of Broca's aphasia. The dysprosody of these patients predominantly reflects disturbed temporal organisation of speech utterances. Altered intonation contours, presumably, result from disordered sentence planning rather than from deficits of pitch processing. Wernicke aphasics may show increased variability of intonational patterns. 3. Impaired discrimination and identification of affective prosody has been observed in patients with temporoparietal lesion of the right hemisphere ("auditory affective agnosia"). With respect to linguistic prosody, controversial findings are reported on. Besides pitch extraction from acoustic signals the right hemisphere seems to provide categorical representations of emotional behaviour required for the "interpretation" of perceived intonation. 4. Damage to the right hemisphere can give rise to monotonous speech devoid of affective modulation ("motor aprosodia"). It is unsettled to which extent linguistic suprasegmental features are also distorted. The available data indicate an underlying dysfunction of basal ganglia loops and/or transcallosal projections. 5. Both Parkinson's and Huntington's disease may present with reduced prosodic modulation of speech. Probably, these deficits reflect disordered motor control of articulatory and phonatory functions. At least with respect to Parkinsonian patients perceptual and acoustic studies have so far failed to provide sufficient evidence of impaired prosodic planning.
