Gamma oscillations: precise temporal coordination without a metronome

Ask your doctor how you can use your brain waves to help your recovery.  Do not back down, they are supposed to know everything about your recovery possibilities.
Gamma oscillations: precise temporal coordination without a metronome

Gamma oscillations in the brain should not be conceptualized as a sine wave with constant oscillation frequency. Rather, these oscillations serve to concentrate neuronal discharges to particular phases of the oscillation cycle and thereby provide the substrate for various, functionally relevant synchronization phenomena.

Figure 1. The relationships between the timing of neuronal spiking activity and the phase of oscillation cycle. Top: a sequence in which five neurons preferentially fire for a given stimulus. Bottom: the relationship to the underlying oscillation cycle, as indicated by local field potentials. These relative neuronal firing times are not constant, but change dynamically as a function of stimulus properties (not shown). Reproduced, with permission, from [4].
