Science with a Touch of Art: A Conversation with David Ginty

If you think about it, the surface of the human body, the skin, is actually one huge sheet of tactile receptors. The dozens of types of receptors that innervate the skin help us connect with our surroundings. But the properties of these neurons – how they are organized in the skin, where the project into … Continue reading

Science Fiction, Serendipity and Interneuron Specification: A Conversation with Dr. Gordon J. Fishell

It is easy to assume that if a car has a gas pedal, it needs to have brakes, and similarly, if our brain has excitatory neurons, it needs inhibition too. For a long time, the field of neuroscience had thought of inhibitory interneurons as the “brakes” of the brain, providing suppression to neuronal activity. However, … Continue reading

Hubel and Wiesel & the Neural Basis of Visual Perception

Snap!  Crackle!  Pop! Those are the sounds that Professors David Hubel and Torsten Wiesel heard in the early 1950s when they recorded from neurons in the visual cortex of a cat, as they moved a bright line across its retina.  During their recordings, they noticed a few interesting things: (1) the neurons fired only when … Continue reading

Understanding the Visual System: A Conversation with Botond Roska

When we see the world, there is a huge amount of processing that occurs in the neural circuits of the retina, thalamus, and cortex before we can even begin to comprehend our environment. And all of this computation happens very quickly! In this interview with Dr. Botond Roska, Senior Group Leader at the Friedrich Miescher … Continue reading

From Stevens to Synapses: A Conversation with Kelsey Martin

Take your wildest guess.  How many neurons make up the human brain?  You’re not guessing wild enough if you said anything less than a trillion.  The circuitry of the human brain consists of a quadrillion (1015) synapses.  These neural circuits aren’t necessarily hard-wired and have the capacity to be re-wired in response to experience. In … Continue reading

Getting Technical: Methods in Neuroscience

It is an exciting time for neuroscience. The BRAIN Initiative (Brain Research through Advancing Innovative Neurotechnologies) is in the spotlight as a part of the new Presidential focus and recently received $46 million in funding grants towards its early efforts. Aimed at revolutionizing neuroscience, the BRAIN Initiative sets out to explore the fascinating underpinnings of … Continue reading
