alpha coherence parietals

[Guest guest]

In a recent email Pete said:

" In the TLC, we would ordinarily look for alpha coherence from 40-70,

so 60 is not bad. If it is down around 40 or below at P3 and P4, then

that might be worth training, though that probably wouldn't be high on

my list for the issues you mentioned. "

What problems can you have from an alpha coherence of 30 in the

parietals? (my daughter has some sensory processing issues could this

be related to low alpha coherence?) I believe I have read that it

doesn't take long to train coherence up. Is this true? Do you do

coherence training for a short time like 3 minutes?

Thanks,

Coherence in slower frequencies like alpha is an indication of how effectively the neurons are going into neutral and (in alpha) remaining in a ready state, present but not processing. Low coherence suggests either that there are differential timing loops between sets of neurons and the rhythm generators in the thalamus or, more likely, that the neurons on the surface of the cortex aren't really letting go very well. They keep trying to burst up into beta.

Problems related could be anxiety, inability to be still and relaxed, difficulty performing sensory integration tasks (in the back of the head) and perhaps some sleep issues.

Some people find alpha coherence to be tremendously positive and restful and calming; others don't get much from it and have a hard time doing it. Try it and see.

All coherence training should be done with linked ear reference and should be done with FIR filters as opposed to IIR filters. Alpha coherence should be done eyes closed.
