“2013’s Nobel Prize Winners” — Podcast 11: James Rothman, Randy Schekman & Thomas Südhof

On Episode 11 of The Connectome Podcast, I’m joined by all three of 2013’s Nobel Prize winners in the Physiology/Medicine category — James Rothman, Randy Schekman and Thomas Südhof! All three of these guys contributed crucial pieces to a longstanding puzzle: How, exactly, do our brain cells communicate with each other? See, biologists had known […]

The Search for a Nobel Prize-Winning Synapse Machine

In this article for Scientific American, I talk with all three winners of 2013’s Nobel prize in physiology or medicine, about the paths that led them to victory. Where did their scientific careers start? Did they have any idea they’d be working in this area of research, let alone discover something as profound as they […]

Three Big Doubts About Brain-Mapping Efforts

Neuroscience research has come a hell of a long way since the days of scalpels and electrodes. While some research teams are exploring the molecular machinery that churns at the hearts of nerve cells, others are working to assemble wiring diagrams for whole regions of the human brain. Just as biological science never looked the […]

The Memory Master

A gene that may underlie the molecular mechanisms of memory has been identified, says a new study. The gene’s called neuronal PAS domain protein 4 (Npas4 to its friends). When a brain has a new experience, Npas4 leaps into action, activating a whole series of other genes that modify the strength of synapses – the connections […]

Synaptic Changes

Synapses – the junctions where neurons communicate – are constantly growing and pruning themselves – and those two processes occur independently of one another, says a new study. As a synapse sees more and more use, it tends to grow stronger, while synapses that fall out of use tend to grow weaker and eventually die […]

Silicon Synapses

A new kind of computer chip mimics the way a neuron learns, a new study reports. The 400-transistor chip simulates the activity of a single synapse – a connection between two neurons. Because of the chip’s complexity, it’s able to mimic a synapse’s plasticity – its ability to subtly change structure and function in response to new […]

Diff'rent Vesicles

A new discovery shows that the rules of synaptic transmission are very different from what we’d thought. In each neuron, tiny sacs called vesicles store neurotransmitter chemicals, and help transport them to other neurons. For decades, scientists had thought all the vesicles of a particular neurotransmitter were more or less identical – but now, they’ve […]
