You enter a phase called REM sleep (REM is short for Rapid Eye Movement) During REM sleep, the rest of your body essentially becomes paralyzed. The release of certain neurotransmitters are shut down and your large muscles do not move.Some people have abnormal REM sleep in which those neurotransmitters do not shut down, and they act out their dreams. Most of the dreams we vividly remember happen during REM, as our brain has higher activity during this phase.

Einstein’s Brain   (…and the neuroscientist who studied it)


Marian Diamond began her graduate work in 1948 and was the first female student in the department of anatomy at UC Berkeley.  The first thing she was asked to do when she got there was sew a cover for a large magnifying machine (?!?!?!?!).

"They didn’t know what to do with me because they weren’t used to having a woman. They thought I was there to get a husband. I was there to learn."

Such challenges were not uncommon. Years later she requested tissue samples of Albert Einstein’s brain from a pathologist in Missouri. He didn’t trust her.

"He wasn’t sure that I was a scientist. This is one thing that you have to face being a woman.  He didn’t think that I should be the one to be looking at Einstein’s brain."

Marian persisted for three years, calling him once every six months, and received four blocks of the physicist’s brain tissue (about the size of a sugar cube).  

Her research found that Einstein had twice as many glial cells as normal males — the discovery caused an international sensation as well as scientific criticism.  

What are glial cells?  Previously, scientists believe that neurons were responsible for thinking and glial cells were support cells in the brain.  Now Researchers believe the glial cells play a critical role in brain development, learning, memory, aging and disease.

This is the very first X-Ray image ever taken, by Wilhem Röntgen. He called them X-Rays because he didn’t know what the hell they were at first. So X as in “Solve for X”
It’s an image of his wife, Anna Bertha Ludwig. Because he was too much of a coward. Well, that’s not true, he had spent weeks with these things and just needed to focus on taking the image. When she saw it she said “I have seen my death” which is a little unnerving.
In 1901, Röntgen won the first ever Nobel Prize for his work into X-Rays. I wonder if he knew how much they’d change the world.
