Re: Mu

[Guest guest]

You know I haven't researched down that path of asking why population

groups have the thrifty gene in the first place. Was it about seasonal

fluctuations? or seven-year droughts? Or only meat fresh year-round?

What is it about northern Europe beyond Ireland too? Hmm, time to put

it on my list of things to read about someday.

(if this is a duplicate just blame , sorry)

You know I haven't looked into that part of theory much.

The one about population groups and the thrifty gene.

Is it about poor food supplies or much farther back, like Ice Age?

Could it be about fresh meat being year-round and fresh plants being

summer only?

Germans, Scandihoovians as we used to say, and Russians? What about

the Pima Indians?

I dunno.

Experientially sometimes I think that what I think of, and I'm one of

them, " Celtic fat girls " metabolize refined fats and refined sugars

as if they were dilithium crystals. A little goes a long, long way.

But we can make great power out of it. How's that for corny!!

Hi and Connie,

Further to the information that Dailey pointed out below, you may like

to have a look at

the new tACS which can modulate the EEG as pointed out in a recent article by

Tino Zaehle,

" Transcranial Alternating Current Stimulation Enhances Individual Alpha Activity

in Human EEG " published by PlosOne. I have been using it in some cases (like

recovery from traumas and strokes) and it

does modulate the EEG in any way you want. You may like to use it together with

the EEG in order to be

sure about the EEG frequency and power the tACS is modulating

I hope this can help you.

Bye for now,

Assunto: RE: Mu

Hello Connie,

Connie asks are there " other ways to address " " mu rhythm suppression issues. "

The new book by Coben and (Academic Press) titled " Neurofeedback and

Neuromodulation Techniques and Applications " has a chapter on transcranial

direct current stimulation (tDCS). I have just placed about 300 tDCS abstracts

(with markups) and links to 100 free full text articles on my website at

www.growing.com/mind. You may find these interesting. It is a safe, inexpensive

and often effective way of modifying the excitability of cortex as well as

network connectivity. It is probably better researched than neurofeedback. It

appears to have the added advantage that it primes neuroplasticity in the cortex

so that further training in other modalities (HRV, HEG, NFB) is more likely to

be effective and long-lasting.

With respect to problems in desynchronization of mu, I will send you the article

(Matsumoto, et al 2010) which is abstracted below.

Best wishes,

Modulation of mu rhythm desynchronization during motor imagery by transcranial

direct current stimulation.

Matsumoto J, Fujiwara T, Takahashi O, Liu M, Kimura A, Ushiba J.

School of Fundamental Science and Technology, Graduate School of Keio

University, Kanagawa, Japan.

BACKGROUND: The mu event-related desynchronization (ERD) is supposed to reflect

motor preparation and appear during motor imagery. The aim of this study is to

examine the modulation of ERD with transcranial direct current stimulation

(tDCS). METHODS: Six healthy subjects were asked to imagine their right hand

grasping something after receiving a visual cue. Electroencephalograms (EEGs)

were recorded near the left M1. ERD of the mu rhythm (mu ERD) by right hand

motor imagery was measured. tDCS (10 min, 1 mA) was used to modulate the

cortical excitability of M1. Anodal, cathodal, and sham tDCS were tested in each

subject with a randomized sequence on different days. Each condition was

separated from the preceding one by more than 1 week in the same subject. Before

and after tDCS, mu ERD was assessed. The motor thresholds (MT) of the left M1

were also measured with transcranial magnetic stimulation. RESULTS: Mu ERD

significantly increased after anodal stimulation, whereas it significantly

decreased after cathodal stimulation. There was a significant correlation

between mu ERD and MT. CONCLUSIONS: Opposing effects on mu ERD based on the

orientation of the stimulation suggest that mu ERD is affected by cortical

excitability.

Mu

Hi all, I have a brother and sister with attention problems and both have mu

rhythem supression issues.

Should I just try to directly get them down or is there other ways to address

this.

Thanks, Connie
