Deans' stroke musings: Gamma oscillations: precise temporal coordination without a metronome

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

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.

Figures and tables from this article:

: 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].
