The Man with a Tiny Brain

Fascinating article from the New Scientist website. Anomalies like this suggest (to me) that mind and consciousness might not be entirely dependent on the brain and I’m interested in that possibility. The article suggests that ‘brain plasticity’ accounts for the normal functioning of a man whose brain tissue was ‘50% to 75%’ reduced but that doesn’t sound entirely convincing.

Man with tiny brain shocks doctors

A man with an unusually tiny brain manages to live an entirely normal life despite his condition, which was caused by a fluid build-up in his skull.
 
Scans of the 44-year-old man’s brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue (see image, right).
 
“It is hard for me [to say] exactly the percentage of reduction of the brain, since we did not use software to measure its volume. But visually, it is more than a 50% to 75% reduction,” says Lionel Feuillet, a neurologist at the Mediterranean University in Marseille, France.
 
Feuillet and his colleagues describe the case of this patient in The Lancet. He is a married father of two children, and works as a civil servant.
 
Not retarded
 
The man went to a hospital after he had mild weakness in his left leg. When Feuillet’s staff took his medical history, they learned that, as an infant, he had had a shunt inserted into his head to drain away hydrocephalus – water on the brain.
 
The shunt was removed when he was 14. But the researchers decided to check the condition of his brain using computed tomography (CT) scanning technology and another type of scan called magnetic resonance imaging (MRI). They were astonished to see “massive enlargement” of the lateral ventricles – usually tiny chambers that hold the cerebrospinal fluid that cushions the brain.
 
Intelligence tests showed the man had an IQ of 75, below the average score of 100 but not considered mentally retarded or disabled.
 
“The whole brain was reduced – frontal, parietal, temporal and occipital lobes – on both left and right sides. These regions control motion, sensibility, language, vision, audition, and emotional and cognitive functions,” Feuillet told New Scientist.
 
Brain adaptation
 
The findings reveal “the brain is very plastic and can adapt to some brain damage occurring in the pre- and postnatal period when treated appropriately,” he says.
 
“What I find amazing to this day is how the brain can deal with something which you think should not be compatible with life,” comments Max Muenke, a paediatric brain defect specialist at the National Human Genome Research Institute in Bethesda, Maryland, US.
 
“If something happens very slowly over quite some time, maybe over decades, the different parts of the brain take up functions that would normally be done by the part that is pushed to the side,” adds Muenke, who was not involved in the case.

Just reviewing some stuff I posted to FB this week:

This exhibition by vegan Frank Medrano impressed me.

My own physical discipline is running but I haven’t done any this week and I missed my Tai Chi and Qigong classes also. But some new year resolutions are in the pipeline.

I was interested in the reports that Syrian nun Mother Agnes had pulled out from a STWC conference in London because of objections from the likes of Owen Jones and Jeremy Scahill. Red Youth ran a decent article on this. George Galloway’s interview with her is worth listening to.

I thought this comment by Jane Fonda was worth sharing and thinking about:

People have been talking about the crisis with masculinity for decades and I remember conversations from the 1980’s and 90’s that were interesting. Interesting but focussing on individual men rather than on the culture of hyper masculinity that is wedded to violence. Male violence is not an accident it is part of the culture as any audit of TV series and films will show.

I shared Tom Morley’s tribute to Nelson Mandela on Friday after we heard of Mandela’s passing:

The problem with FB is that FB pages do not make it easy to review/reflect on and develop from stuff that has been posted. Less continuity.
