New York, Sep 1 (IANS): This may sound and read unbelievable but there is an elderly man whose brain has no neural fibre connection between his two hemispheres!

For a layman, human brain is divided into two hemispheres and the main connection between them are million of neural pathways called corpus callosum.

But this man, H.W., aged 88, had no corpus callosum, wired.com reported quoting doctors.

The main channel between his two brain hemispheres was completely missing.

In medical terms, he was suffering from agenesis of the corpus callosum, meaning he was born with this structure missing.

To physicians' surprise, he led a normal life in the military and later as a flower delivery man.

Recently, he complained of some mild memory difficulties.

"This case study underscores the plasticity of the developing brain," said doctors from the Veterans Affairs Eastern Colorado Health Care System who were part of the team that diagnosed the rare brain condition.

In some cases, the callosum is sliced as a radical treatment for epilepsy.

People who receive this treatment are referred as split-brain patients, the report added.
