( TS-Si Science Access / Neuroscience )
Cold Spring Harbor, NY, USA. It has probably happened to everyone at one time or another. You're driving to a restaurant for the very first time. At a crossroads, you make a turn. You drive for several minutes, and then several minutes more. Nothin

Bristol, UK. When we are confronted by threatening siruations, the speed at which we react could have life or death implications. In our distant and more primitive past, the application of speed and wit could have meant escape from a wild anim

Vancouver, BC, CAN. Entering the world, we reach out to our environment, with a brain map of essential pathways for exploration. But what really goes on between our brains, eyes and appendages? And how do we process the information necess
June 16th, 2008
( TS-Si Science Access / Neuroscience )Pittsburgh, PA, USA. Sharing our experiences depends on our ability to visualize and describe the contents of our memories. Prediction of future actions by ourselves and others is founded on our here-and-now processing of images and language. Th

( TS-Si Science Access / Neuroscience )Rehovot, Israel. Women refer to the smell of testosterone; this is an especially common occurence for HBS females following transition. Men generally catch a female's biological scent of estrogen before turning their attention to other womanly a
June 1st, 2008
( TS-Si Science Access / Neuroscience )Cold Spring Harbor, NY, USA. Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. A research team has identified molecules guiding this highly spe
May 23rd, 2008
( TS-Si Science Access / Neuroscience )Bethesda, MD, USA. Does your position in a social hierarchy strongly influence your motivation and impact on your physical and mental health? Yes, M'am. Studies have shown that social status strongly predicts health. Animals chronically stressed
May 1st, 2008
( TS-Si Science Access / Neuroscience )Chicago, IL, USA. As children know, answering the question how many are there? means you must add up individual objects in a group to get an answer. This is a cognitive ability is shared by animals as diverse as humans and birds, but the exact brain
April 27th, 2008
( TS-Si Science Access / Neuroscience )Paris, France. A neurotransmitter receptor is a protein on the surface of a cell that binds to receptors on the surface of another cell. The receptors move very rapidly, with a mobility that plays an essential role in the passage of nerve impulses fr
April 26th, 2008
( TS-Si Science Access / Neuroscience )Leipzig & Berlin, Germany. Human survival depends on the ability to make appropriate choices. Selecting the best course of action is a complex process that integrates motivational states, raw sensory information, and analysis of potential outcome
April 17th, 2008
( TS-Si Science Access / Neuroscience )Amsterdam, The Netherlands. The option to choose among several courses of action is often associated with the feeling of being in control. Yet, in certain situations, one may prefer to decline such agency and instead leave the choice to someone else
April 7th, 2008
( TS-Si Science Access / Neuroscience )Augusta, GA, USA. Dr. Joe Z. Tsien was a sophomore in college searching for some meaningful extracurricular activity when he heard the neurons speak. He had stopped by the lab of a brain researcher at Shanghai’s East China Normal University.

March 30th, 2008
( TS-Si Science Access / Neuroscience )St. Louis, MO, USA. A brain network linked to introspective tasks — forming the self-image or understanding the motivations of others — is less intricate and well-connected in children, scientists have learned. They also showe
March 14th, 2008
( TS-Si Science Access / Neuroscience )Baltimore, MD, USA. Humans think about thinking because we actively control the thinking processes involved in learning. But how do we suspend that capacity, called metacognition, and why should we do so in the first place? After all, metacognition s
March 3rd, 2008
( TS-Si Science Access / Neuroscience )Stockholm, Sweden. A neurotransmitter is a chemical that permits nerve signals to bridge the gap, or synapse, between nerve cells. Basically, it is a chemical used as a messenger from one nerve cell to another. Serotonin is believed to play an import
