The Science of Watching Memories Form By Erin Mae Dul
By using advanced imaging techniques researchers from the Albert Einstein College of Medicine of Yeshiva University have captured a video of mRNA in motion, shedding light on how the brain creates memories in real time, focusing on neurons. The molecules of mRNA pertinent to making memories were marked with fluorescent “tags” within a mouse model the scientists had developed so they could watch the process unfold live within living brain cells.
"It’s noteworthy that we were able to develop this mouse without having to use an artificial gene or other interventions that might have disrupted neurons and called our findings into question," said Robert Singer, Ph.D., the senior author of both papers and professor and co-chair of Einstein’s department of anatomy & structural biology and co-director of the Gruss Lipper Biophotonics Center at Einstein. He also holds the Harold and Muriel Block Chair in Anatomy & Structural Biology at Einstein. [x]
Basically, some neurons located in the mouse’s hippocampus, where memories are stored and created, were stimulated by the Einstein researchers. After stimulating the neurons, they were then able to observe the tagged beta-actin mRNA molecules form within the nuclei of neurons and make their way traveling within the branched projections of the neuron, also known as dendrites.

Empathy, Art & Entertainment
At his Google talk (“The Neuroscience of Empathy”), UCSF’s Dr. Thomas Lewis answers the question:
Are depictions of destruction and pain in art designed to blunt our sense of empathy?:
“If art works, it makes you feel something and often, say in a novel in which you identify with the characters, if something bad happens to them it is somewhat painful for you. So I think good art evokes [empathy]. I think entertainment blunts it. So, say if you see a mass market entertainment film…I just saw the Bruce Willis film —not to say it’s bad, which it’s not, but— Bruce Willis is tossed about like a rag doll throughout the course of the film. Nothing bad happens to him. He doesn’t break any bones. He doesn’t suffer visibly at any point. That, I think, does blunt our empathy: entertainment. But art shouldn’t do that. And actually it is one of the fundamental distinctions between art and entertainment that’s worth describing.”
