“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
In any major mapping expedition shouldn’t the first priority be to survey the uncharted regions? In mapping the brain, that would be charting the neglected half–glia.
The Brain Mapping Initiative announced by President Barack Obama earlier this year seeks to map and monitor the function of neural connections in the entire brain of experimental animals, and eventually in the human cerebral cortex. Several researchers have raised doubts about the project, cautioning that mapping the brain is a far more complex endeavor than mapping the human genome, and its usefulness more uncertain.

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
In this episode, we talk about neural simulation, the relation between the mind and the brain, ion channels that make neurons excitable and neuroscience research in fly larvae. Participants are Erin McKiernan, Jean-François Gariépy, John Kubie, Leanne Boucher and Steven Miller. Continue reading
Are political preferences the product of our biology, our brain, or simply of the environment in which we are educated? In this series of articles cross-posted in French in the Québec version of the Huffington Post, I have a look at the studies that have explored these questions in recent years. Continue reading
