“…Additionally, temporal and parietal lobe areas as well as posterior corpus callosum were involved. The predominant contribution of anterior corpus callosum to frontal and posterior corpus callosum to temporo-parietal coherence agrees with an anterior-posterior topology of fiber systems passing through the corpus callosum as suggested by a wide range of animal and human studies [De Lacoste et al, 1985;Pandya and Seltzer, 1986;Schaltenbrand et al, 1970]. The contribution of fiber tract integrity in subcortical centers such as thalamus and cerebellum was less pronounced for frontal coherence than for temporo-parietal coherence.…”

Interhemispheric coherence derived from electroencephalogram (EEG) recordings is a measure of functional interhemispheric connectivity. Diffusion tensor imaging (DTI) determines the integrity of subcortical fiber tracts. We studied the pattern of subcortical fiber tracts underlying interhemispheric coherence and its alteration in 16 subjects with amnestic mild cognitive impairment (MCI), an at risk syndrome for Alzheimer's disease, and 20 cognitively healthy elderly control subjects using resting state EEG and high resolution DTI at 3 T. We used a multivariate network approach based on principal component analysis to determine effects of coherence on the regional pattern of diffusivity. Temporo-parietal coherence in the alpha band was significantly correlated with diffusivity in predominantly posterior white matter tracts including posterior corpus callosum, parietal, temporal and occipital lobe white matter, thalamus, midbrain, pons, and cerebellum, both in MCI subjects and controls (P < 0.05). In MCI subjects, frontal coherence in the alpha band was significantly correlated with a predominately frontal pattern of diffusivity including fiber tracts of the anterior corpus callosum, frontal lobe white matter, thalamus, pons, and cerebellum (P < 0.05). The study provides a methodology to access specific networks of subcortical fiber tracts subserving the maintenance of interhemispheric resting state coherence in the human brain.

“…In our stereotactic laboratory, we followed the indications which had been proposed by Spiegel and Wycis [1950], Orchinik et al [1950], Spiegel et al [1964], Riechert [1957], by Hassler and by Narabayashi for the treatment of intractable pain, parkin sonism, extrapyramidal hyperkinesias, compulsion disorders, erethism and pituitary disorders. The results were partially published by Schaltenbrand [1966] and Schaltenbrand et al [1965Schaltenbrand et al [ , 1970Schaltenbrand et al [ , 1971Schaltenbrand et al [ , 1973Schaltenbrand et al [ , 1974 and by Kleinfelder et al [1964] and N adjmi and Borner [1968].…”

“…Electrical stimulation of the CC established the motor function and topographic representation of the body of the CC in the monkey long before anatomy: “When the electrodes are applied over and just behind the genu, head and eye movements are produced; further back movements of the arms and shoulder and of the upper part of the trunk; then movements of the forearms and general movements of the hands and fingers; then of the lower part of the trunk and tail, and lastly, movements of the lower limbs” ( Mott and Schaefer, 1890 ). Schaltenbrand et al (1970) reported the results of CC stimulation in 9 patients. Depending on the stimulated site they obtained movements, paresthesia, as well as interference with speech and thinking.…”

Highlights The functional characterization of callosal connections is informed by anatomical data. Callosal connections play a conditional driving role depending on the brain state and behavioral demands. Callosal connections play a modulatory function, in addition to a driving role. The corpus callosum participates in learning and interhemispheric transfer of sensorimotor habits. The corpus callosum contributes to language processing and cognitive functions.
