Morphological Correlates of Bilateral Synchrony in the Rat Cerebellar Cortex
The bilaterality of afferents to the IO was investigated using anterograde transport of PHA-L from the dorsolateral hump of the cerebellar nuclei and the spinal trigeminal nucleus.
The possible role of the bilateral trigeminal afferents of the IO in controlling the bilateral synchrony in crus IIA may not be as prominent as that of the stronger bilateral projection to the IO from the dorsolateral hump of the cerebellar nuclei.

However, throughout this manuscript, the term bilateral deficit shall be used as the definitive descriptor of the bilateral deficit, regardless of its manifestation.
Shantz et al., (7) were dissatisfied with the supposition that the bilateral deficit was attributable to an inability of the CNS to fully coordinate maximal activation of MUs in activities requiring intensive participation of large muscle groups.
Therefore, it was concluded that the bilateral deficit phenomenon was not simply attributable to the inability of the CNS to maximally activate a large number of muscles simultaneously (7).

Jerks of massive bilateral myoclonus mainly involve the upper limbs, with elevation of the shoulders producing slight contraction of the trunk.
Massive bilateral myoclonus can be asymmetrical, and it is a challenge in clinical practice to distinguish within asymmetrical jerks those that correspond to focal jerk with secondary generalization from those that correspond to generalized although asymmetrical jerks.
Hyperexcitability in the motor pathways permits synchronization in the rolandic and thalamic structures, the discharge in one structure triggering the discharge in the other structure, and the cycle is closed.

 Neil Fraser: Writing: Differential Synchronization
Since this synchronization scheme operates in real-time, any such conflict implies that two (or more) users have their attention focused on that location.
If bilateral changes result in a synchronization failure, and Client Text and Server Text do not match each other at the end of a cycle, the problem is simply reattempted on the next cycle.
Frequent synchronizations running unnoticed in the background result in only a few second's worth of typing to be corrupted in either case.

 hemisync
Bilateral hemispheric synchronization is a phenomenon which has been attracting the attention of researchers and clinicians for sometime.
Lindsley (1952) characterizes synchronized, optimal alpha rhythm as a state of relaxed wakefulness in which attention tends to wander, free association is enhanced, and behavioral efficiency of routine reactions and creative thought is good.
The synthesizing of the two tones into one experienced tone produces a phenomena known as hemispheric synchronization, where the electrical activity of the two hemispheres of the brain unite into a single synchronous pattern with an overall frequency at the frequency of the difference between the two original tones.

The aim of this work was to study the degree of synchronization within the portion of the somatosensory cortex devoted to hand control during external sensory stimulation.
The properties of this dynamic synchronization index within the beta [16-32 Hz] and gamma [36-44 Hz] bands suggest that the hand representation in humans’ primary cortex follows a frequency coding, in addition to the somatotopic one, for discriminating different districts.
Comparative analysis of synchronization index and signal amplitude showed that this frequency selectivity regarded the synchrony among activated neurons and their number.

 In Search of Empirical Theories
One important observation that we made in a number of Hemi-Sync studies was that subjects exposed to the same Hemi-Sync signals achieved bilateral synchronization at different frequencies.
Should we be able to continue to support this theory with further research, we may conclude that Hemi-Sync is indeed a technology beyond entrainment and for that matter it is one of the safest modalities for health improvement and enhancement.
Based on studies observing the electrocortical activity of patients undergoing psychotherapy, it appears that moments of insight and "clarity" are preceded by moments of bilateral synchrony (see Sadigh, 1991b).

Comparison of movement times in individual limbs and the synchronization interval between the limbs before and after a bilateral lesion in the mesial-frontal cortex of a monkey trained to perform the bimanual drawer task.
Whereas the lesion resulted in a massive prolongation of the individual limb movements (A and B), goal synchronization (C = B – A) and the interlimb correlation coefficient (before lesion, r = 0.927; after lesion, r = 0.956) were not significantly changed.

The secondary activity was that of synchronized Alpha activity.
The results and findings of this study were virtually identical to those observed in the second study: asynchronous mixture of Theta and Alpha waves during the baseline phase followed by highly synchronized Beta activity across the cortex during the treatment phase.
Thus far, we have been able to document that the only effect technology that indeed results in bilateral hemispheric synchronization is that of the Hemi-Sync signals developed by Robert A. Monroe.

In some signaling systems, non-information-carrying signals may be inserted to facilitate synchronization; e.g., in certain forms of binary modulation coding, there is a forced inversion of the signal state at the center of the bit interval.
In these cases, the synchronization signals are included in the calculation of the rate in bauds but not in the computation of bit rate.
The synchronization is achieved by detecting the transition in polarity for 1 bits in the data stream.

However, the present study concludes that there is synchronization between the cardiac heart and the lymph hearts and that the posterior lymph hearts in both Rana catesbeiana Shaw, 1802 and Bufo marinus (L., 1758) beat synchronously as well.
Results show that there is clear synchronization between the lymph heart systoles of two bilateral posterior lymph hearts.
These results support the conclusion that synchrony is characteristic of the anuran lymphatic system and that synchronization of the cardiac heart and the lymph hearts could impart an energetic advantage that benefits fluid homeostatic mechanisms.

The XCN Server’s purpose is to act as a data repository and to handle the bilateral synchronization logic.
The connector's purpose is simply to apply the data in the context of the client application when data is received from the software server, or if data is created, modified, or deleted by the connector application, to wrap the data object into the xml blob and send it to the software server.
Due to the flexibility and extensibility afforded by this architecture, the specific items within a record can be easily extended since the XCN server does not have to individually manipulate or modify the data record that it is managing.

By recording neural activity simultaneously in left and right HVc of awake, vocalizing male zebra finches, we have shown that vocal premotor neurons are highly synchronized during specific portions of the song motor response.
Because synchronization occurs independently of the recording sites within HVc in either hemisphere, we believe that most HVc motor units are globally synchronized.
For clarity, only the bilateral feedback pathway from DM to UVa is shown.

 Disconnection Procedures in Pediatric Epilepsy Surgery
The rationale for corpus callosotomy is to control generalized seizures by interrupting seizures as they evolve from the cerebral cortex and secondarily spread through commissural pathways.
Interruption of this generalization or bilateral synchronization can reduce or eliminate the major seizure type exhibited by this spread, namely "drop attacks," or atonic seizures.
The goal of MST is to interrupt the horizontal coursing intracortical fibers, thereby isolating localized interactions between the regions of cortex and decreasing the likelihood of synchronized neuronal discharge over a wide expanse of cortex.
