With cross-hemispheric communication severely impaired due to the commissurotomy, the left hemisphere, controlling speech, had information about one part of the visual stimulus, while the right hemisphere, controlling some aspects of movement (especially the left hand) had information about a different part.
A limitation of our study is that there is no inter-hemispherical synchronous stimulation control condition for comparison to our cross-hemispheric stimulation.
Oscillations are often generated by two symmetrically located neural generators, one in each hemisphere [23], [24], [25], [26], and modeling suggests that cross-hemispheric sinusoidal tACS can disrupt neural functions governed by inter-hemispheric phase synchronization [21].
NL has a left temporoparietal lesion without right hemisphere damage and DTI imaging suggests that he has preserved cross-hemispheric connectivity, arguing against an account of PWD as a disconnection of left lateralized language areas from auditory input.
In this paper, I present some exploratory dynamo calculations illustrating the influence of cross-hemispheric coupling in solar cycle models based on the Babcock Leighton mechanism of poloidal field regeneration.
Using two very distinct formulations of Babcock Leighton dynamos, I examine the issues of cross-hemispheric phase lag, interference, and synchronization of Maunder Minimum-like episodes of suppressed activity.
Although covering only a small fraction of the model's relevant parameter space, results presented here suggest that additional effects, such as transequatorial flows for example, may be required to achieve sufficient cross-hemispheric coupling in this class of solar cycle models.
Cross-hemispheric tACS disrupted low frequency oscillation generation in afternoon nap.
We hypothesized that sinusoidal cross-hemispheric frontal tACS would disrupt slow oscillation generation, inhibiting SWA and memory consolidation.
The selection of the corpus callosum in RAVLT indicates that cross-hemispheric communication is important for verbal learning.
Cross-hemispheric tACS disrupted the generation of the slow and delta oscillations of SWS and thus appears to have causally disrupted declarative memory consolidation.
