December 2016: Congratulations to Ryan Natan on defending his PhD! Ryan crushed it at his defense, and I am so very proud of the beautiful data that he presented. His family much enjoyed the elaborate introduction relating very high-level concepts of cortical coding to our everyday experiences. Good luck to Ryan at Janelia! Don't forget to come and visit!
November 2016: Congratulations to John Briguglio on the successful defense of his PhD thesis! John gave a great talk that convinced even the most theoretical physicists that we can learn a thing or two from neuroscience. Here's to a successful postdoc at Janelia!
November 2016: Come see our posters at APAN and SFN!
November 2016: Congratulations to Maria for receiving the Young Investigator Spotlight award at the Advanced and Perspectives in Auditory Neuroscience Meeting!
May 2016: Congratulations to Ryan, Isaac and Laetitia on yet another awesome paper! In this paper in Cerebral Cortex, we show that neurons in the auditory cortex modify their response properties to sounds depending on their ringing quality -- e.g. the sound of a bell has prolonged ringing, which is termed temporal correlation, whereas the sound of static noise has very low temporal correlation. This paper nicely complements a series of findings in our lab of how neurons adjust their response properties to represent sounds across different acoustic environments.
March 30: Tune in at 2 pm today to the online chat hosted by Maria on how to advance in your career in neuroscience.
