Synchronized oscillations can occur between homologous points on the two
Simultaneous extracellular recordings from the two hemispheres reveals
that activity may be synchronized between these two brain regions. Sectioning
of the corpus callosum resulted in abolition of this synchronized activity,
indicating that cortico-cortical connections are important for its generation.
D is the autocorrelagrams of activity in the left and right hemispheres,
while E is the cross-correlagram between the two hemispheres demonstrating
the synchronized activity.
