Bob Muller, close friend and collaborator, died two weeks ago. I met Bob in the early 1980s. I was a post-doc, learning to record from single neurons in Jim Ranck’s lab at Downstate Medical Center in Brooklyn. Bob was a young faculty member who worked down the hall. Although Bob was doing esoteric work, studying the physics of single channels in membranes, his early graduate work had been in brain-behavior relations and he wanted to return to the study of behavior.

“Listen to your conscience,” my mother would say.But where does that mysterious urge to do what is right come from? Scientists have now pinpointed the brain circuitry that compels us to behave according to social norms; moreover, researchers can boost a person’s fairness by exciting this brain region, and promote cheating by inhibiting this bit of brain tissue.
The brain is a beautiful thing. It’s maybe not what most people think of as beautiful – I don’t think many people gaze into the gyri and canadian pharmacy online sulci of the brain and imagine a world in which they grab onto the temporal lobe and go lobe-in-hand into the moonlight. But it has a certain quality about it that inspires awe in the natural world. It is aesthetically pleasing and it “delights the senses” and so it fits the definition of most online (and print) dictionaries. Continue reading
Brains are made of plastic. Seems like a ridiculous claim. The brain is not made of plastic. Or, is it? In neuroscience we often refer to the brain as being plastic, but, what is plastic? The definition that most of us are familiar with is the material known as plastic. Continue reading
In this episode, we look at the extraordinary evolutionary history of the genes related to the synapse which were present even before the evolution of neurons. Our guest is Kenneth S. Kosik from UCSB. Continue reading
Ever had the experience of smelling something and then being automatically transported back in time? It’s as though your olfactory sense is the “on” switch to your memories. Continue reading
Grid Cells in rat entorhinal cortex were discovered in the Moser lab in Trondheim, Norway. These cells were first described in a paper in Nature 20051; For the past 8 years these neurons have been objects of intense study. As the New York Times reports, a paper published yesterday in Nature Neuroscience2 indicates rats aren’t the only animals with grid cells; people have them, too. What are grid cells and what is the significance of recording them in humans?
