We must all have had sleepless nights. Now there seems to be a scientific reason as this study from 31st August shows …..
|You’re lying in bed.
Random thoughts are filling your head
and you’re dreading the night
when the churn of your mind takes flight.
A wandering mind,
It’s a mind that simply can’t find its way
31st August 2013 – headline from the Daily Mail
Notes: “An uncontrollable wandering mind plays a key role in primary insomnia, according to a new study of insomniacs’ brain scans.” Brain scans of insomniacs have revealed how regions of the brain associated with wandering thoughts do not shut down when the brain is given complex tasks, making sufferers put more effort into daytime jobs than healthy sleepers. Primary insomnia is a form of the condition where sleep is interrupted without the patient suffering any other condition such as depression or chronic pain caused by a medication or substance abuse. In people without the condition, parts of the brain used for ‘working memory’ are switched on and off selectively in order to complete tasks in the most efficient way possible, a process interrupted in primary insomniacs. Insomnia subjects, however, do not properly turn on brain regions critical to a working memory task and do not turn off ‘mind-wandering’ brain regions irrelevant to the task.
