Rhythms of the brain


Rhythms of the brain
In a real life brain networks, there is no top or bottom up process signals because the activities of the neurons can be transmitted to any level. It was reported by Gyorgy Buzsaki in his book mentioned above (2008) that the messages of the neurons between the area of the cortexes can be exchanged by oscillations, resonant loops, or transcient oscillatory coupling.In the context of a workng memory in human brain, the nested gamma oscillations can be used for grouping cell assemblies from a theta cycles. Holding and shifting the sequences in subsequent theta cycles can serve to represent episodic memories. Repeated episodic memories in hippocampus can translate into sematic memory.
