I had a 'perm' today. - E.E.G.

 “I had a perm today”.    EEG


While visiting the hospital

Periodically,

From seven years, for thirty more

Two or three times, annually


My mother did go with me

When way too young, I was

To visit doctor by myself,

To find outlying cause.


Before one visitation,

It had been pre arranged

That I would have an EEG

To see if things had changed


An Electo-Encphalo-Graph

I’d never had before

So mum was reassuring me

It wouldn’t, at all, be sore.


Describing it quite easily 

As when she had a perm.

With ‘lectrodes attached to my head,

Uncomplicated term 


So when I was much older

To visit doc alone,

I aye reported back to mum

Just how things were goin’


Now when an EEG was done

And mum asked how things went

Told her “I had a perm today”

Knew ‘xactly, what I meant.



History of the #encephalogram
In the middle of the 19th century, it was established that muscle tissue and the brain emit weakly Electric signals. For the first time, the activity of electric waves was investigated by the #Englishman Cato and the Russian #Danilevsky. It was only in 1924 that the first encephalography of the brain was recorded by the scientist #Pravdich - #Nemitsky, and the German scientist Hans Berger introduced the concept of the encephalogram.
This method was put into practice in 1934. Currently, doctors refer to the name in the abbreviated form as the abbreviation EEG - EEG.
Electroencephalography (EEG) is a technology for measuring the electrical activity of your brain.
It was the first brain research technology, which remains one of the most frequently used research methods for diagnosing various brain problems, along with #MRI and CT scans.
Here's how an #EEG machine works: Every time a #synaptic connection is made between your neurons, they generate a small amount of electrical energy known as an action potential. When millions of neurons are synchronously connected to each other by synaptic connections, these electrical signals are amplified and can be measured through the skin.
Small conductive plates (electrodes) are fixed in contact with the upper part of the scalp, which records these electrical activities.

"Wake me up before you go go"

 The title of this ode, is a song by WHAM from the '80's.      WAKE ME UP BEFORE YOU GO GO   I heard that song this morning  On local radio Evoking strong memory Of really long ago. Was traveling from homeland That's Belfast, (north, six miles) To London's Heathrow airport, The song brought back some smiles. I sailed to Stranraer's harbour From our port, town of Larne Then o'ernight train going southbound Arriving there earl' morn. To catch my next connection Vancouver bound was I, The train ride, it was cheaper Than 'nother plane to fly Whene'er the train I boarded No seats avail'ble were Some military men were on them, Stretched out, without a care. I couldn't hear them snoring Or see the dreams they had But felt their tired demeanour To waken, would've been bad. Recall me having thought tough, How 'xhausted those men were, And how I'd feel if woken, To do so, wouldn't dare. The lines of song to my mind Came flooding back to...

That's a very good question / They LOVED me./ Night after Christmas

        Look for Dan, Similar style to me. I will give the title of this ode at the end & you'll understand why, when you hear it. One phrase I've noticed past few years, Which irks me to extreme, Is heard in MANY interviews On media, it does seem. When being asked some questions, To information, give, Instead of starting th'answer off, This phrase, repeated, is. The first few times 'twas novel, But aft. a while, does tire, I feel like stretching out my hand, It sure does produce 'ire' It's heard also in general chat, In public, private too, Wherever folk do congregate  Or cause hullabaloo. It may be said on impulse, To have few seconds more, In order to form answer, For me, it irks, hearts, core. Of course it's a good question, Why ever ask one, bad ? Just give an answer to what's asked, Try not, to make me mad.(der) So what is it that irks me, That causes such aggression, That makes my teeth just grate with rage? Well, '' That's a v...

Addenda to 'Who is this man'

Who is this Man Addenda (in blue) to an anthem by Mary Kay Beall entitled Who is this Man? sung in my home church choir a few years ago. Who is this man upon a cross By love's decree, brought low? They say He came to save the world Because God loved us so The King of Kings And Lord of Lords Eternally He'll reign Can it be true He died for me And yes, would die again Who is this man upon the cross? He is a friend to me And though I oft Him disappoint His love has set me free The King of Kings And Lord of Lords He took my sin and pain And yes it's true He died for me, But will return again
