今日から新学期がスタートですが、我が家はなぜか家にいます（爆）
私の体調不良が続いていて、疲れがとれないし、のどがすごく渇くし・・・いやだな〜と思っていたら、２〜３日まえから腰のあたりに　ぷち　ぷち　とちょい芯のあるような痛い吹き出物が・・・あ〜〜〜すごく嫌な予感がする・・・と思っていたら、出てしまいました・・・とうとう・・・帯状疱疹が・・・（涙）
身体がとても疲れていて、どんなに水分をとっても身体の乾きがおさまりません。年に１回ぐらいあるんですが・・・これから数日間は　点滴と強い薬を飲んで　家で休みます。
すぐにうつる・・ということは無いんですけど、学校は小中一貫校なので、「水疱瘡」の菌を持っている私が学校に行くことも　自分で気になるし・・体力もないので数日　お休みをすることにしました。
まこちゃん　ごめんね〜〜〜☆です。
「おかあさんは　シックです。かわいそうに〜〜〜☆」といたわってくれます。鬼婆のママをいたわる天使のような息子・・・癒されます　とっても「ありがとう・・・」と心から思います。

専門的な記事を読んでも、自分では何ともしようがないことがあります。
それでも、記事を読んで　何か　まこちゃんの助けになる事が書いてあったらいいな・・・という思いで、時々　ニュースを読んでいます。
まこちゃんが　私に反応を示さなかったときに、単純に　声が聞こえないのではなく、脳に信号として入っていないのではないか？　入りづらいのではないか？と思って、言語の周波数で考えたことがありました。
英語が優位に入る耳は　お腹に入っていた時にニューヨークに住んでいた（駐在員で）こともあるけれど、日本語がはいりづらくなっているのなら、どんな信号でもいいから　反応してくれる物がほしい・・・と　当時は切実な思いがありました。
障害発症時、まこちゃんは　親に反応しないだけでなく、何にも興味を示すことはありませんでした。食べることも飲むことも・・・何も反応が無かったのです。口をあけさせて　口に入れて食べさせていました。
何でもいい・・・反応してちょうだい・・興味を示してちょうだい・・・まこちゃんがちょっとでもさわった物を何でも買いました。『反応してほしい』あの頃の私は　それだけを願っていました〜今と比較すると　いまは　なんて贅沢な悩みなんだろうと思います。
それにしても、ヘルツとか聴覚とか・・・素人の私にはわかりづらい・・・。この記事で本当は何がわかるのか・・私には　わかっていない気がするんですけど・・・きこえづらい音がやっぱりあるのかな？という感じです。

聴覚のことを　わかりやすく書かれている学校の先生のＨＰがありました。

『自閉症児の脳の特定領域で反応異常が認められる

Research May Unlock Mystery Of Autism's Origin In The Brain
24 Aug 2007

In the first study of its kind, researchers have discovered that in autistic individuals, connections between brain cells may be deficient within single regions, and not just between regions, as was previously believed.
Tony Wilson, Ph.D., lead researcher and assistant professor of neurology at Wake Forest University School of Medicine, said he hopes this study will eventually lead to earlier diagnosis and more targeted medications for autism.
Using magnetoencephalography (MEG) brain imaging technology to measure brain electrical activity, the researchers administered a test called the 40 hertz (cycles per second) auditory steady-state response test. The test measures electromagnetic wave cycles and indicates brain cell discharges at the 40 hertz frequency.
"This test measures the brain's capacity to mimic what it's hearing. A healthy brain's cells will fire back at 40 hertz," said Wilson. "We chose this test because it is a robust metric of how well individual circuits are functioning."
The results were reported in this month's issue of Biological Psychiatry.
A group of 10 children and adolescents with autism, and 10 without autism, listened to a series of clicks occurring every 25 milliseconds (ms) for a duration of 500 ms. The MEG measured the brain's responses to these clicks.
In the right hemisphere of the brain, which controls attention and spatial processing, there was no significant difference in the groups. But the results showed a considerable discrepancy between the two groups in the left hemisphere, the area of the brain that controls language and logic.
In the auditory area of the left hemisphere, the group without autism delivered a brain response to the 40 hertz stimulation 200 ms after it began. However, the group with autism failed to respond entirely at the same 40 hertz frequency.
"Our results made sense. Both anecdotal and behavioral evidence suggest children with autism have significantly disturbed brain circuits on the local-level within an individual brain area," said Wilson. "For example, they tend to restrict their visual gaze to a part of someone's face, like a nose or an eye, but not the person's whole face."
The results also support previous research that showed disconnections between two or more brain regions, known as long-range connectivity. This new study supports the idea that the network as a whole is broken, but shows the disconnection in long-range connectivity may actually start within individual brain regions, known as local connectivity.
Wilson explains the difference between local and long-range connectivity using vision as an example. "With vision, one part of your brain identifies color, another perceives motion. Within each of these areas of your brain, there is local connectivity between brain cells that allow the region to do its job. When you see a red ball flying across the room, both of these areas of your brain start communicating with each other and put together flying and red as qualities of the same ball. That's long-range connectivity."
Wilson conducted the autism research while at the University of Colorado, but says he hopes to continue his autism research at Wake Forest.
"I chose Wake Forest because it has one of the most advanced MEGs in the country. Here, we can study the brain at a very precise level," said Wilson.
Co-authors on this study were Donald Rojas, Ph.D., Martin Reite, M.D., and Peter Teale, M.S.E.E., with University of Colorado, and Sally Rogers, Ph.D., with University of California-Davis.
Wake Forest University Baptist Medical Center is an academic health system comprised of North Carolina Baptist Hospital and Wake Forest University Health Sciences, which operates the university's School of Medicine. U.S. News & World Report ranks Wake Forest University School of Medicine 18th in primary care and 44th in research among the nation's medical schools. It ranks 35th in research funding by the National Institutes of Health. Almost 150 members of the medical school faculty are listed in Best Doctors in America.
