Lightning in Your Brain

I awoke this morning to a ferocious lightning storm.  The house shook from thunderous booms. The predawn darkness blanched in blazing white flashes.  Lightning is impressive; especially in contrast to the feeble bioelectricity generated by the body’s nerve cells.  Or is that just an illusion?  Neuroscientist Michael Persinger has done some back-of-the-envelope calculations that may surprise you.

The Detroit River

David H. Hubel’s great gift to neuroscience.

David H. Hubel, whose work unveiled fascinating brain processes that underlie our sense of vision, died last month at the age of 87.

Hubel’s parents were Americans, living in Detroit, Michigan. His father had a job in Windsor, Ontario. Tired of commuting across the Detroit River, he moved to Canada, where David Hubel was born. During his childhood David spent considerable effort learning to play the piano, and later the flute. In 1929, the family moved to Montreal where David Hubel grew up. Continue reading
