Why mosquitoes love us Knowing Neurons

Why Mosquitoes Love Us

From that evil itch on your arm to torturous diseases such as malaria, Zika, dengue, and yellow fever, mosquito bites can have unpleasant consequences. But have you ever wondered why those skin-diving insects are so good at detecting humans? Not so surprisingly, the answer lies in neuroscience — in a special field called chemosensation, the sensing of chemical stimuli.Continue reading

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

David GintyIf 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 the spinal cord and brainstem, and how this organization gives rise to the sense of touch – are actually poorly understood! I spoke with David Ginty, Ph.D., who is Professor of Neurobiology at Harvard Medical School and an investigator with the Howard Hughes Medical Institute, to find out about the newest ways his lab is studying sensory biology.Continue reading

Understanding the Visual System: A Conversation with Botond Roska

Botond_RoskaWhen 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 Institute for Biomedical Research in Basel, Switzerland, we discuss his research on the elements of the visual system that compute visual information as well as how this knowledge can be used to help blind patients. Dr. Roska was inspired by the work and scientific approach of David Hubel (more about this on Wednesday!), and continues to follow his example: “Listen to the experiment, and not your colleagues,” says Dr. Roska. But what would he be, if not a neuroscientist? Find out in my conversation with Dr. Roska, who also shares his story of transition from musician, to medicine, to mathematics and to neuroscience!Continue reading
