  • MBI Researchers Publish in Neuron

     

    MBI graduate student Doug GoodSmith and postdoctoral fellow Xiaojing Chen published a new paper in Neuron. This paper resulted from a collaboration between the Knierim lab of MBI and Kim Christian of the Song lab of the JHU Institute for Cell Engineering.  Their findings described the spatial firing characteristics and pattern separation properties of different cell types in the dentate gyrus region of the hippocampus.

  • Knierim Lab Publishes New Paper in eLife

     

    Research Scientist Francesco Savelli of the Knierim lab published a new article on the functional properties of “grid cells”—the brains’ “internal GPS”—in the journal eLife.  This paper showed that the spatial tuning of these cells are strongly influenced by remote visual landmarks, in addition to the well-known influence of geometric boundaries of the environment.

  • MBI Researchers Awarded New Collaborative Grant     

     

    MBI Professors Ernst Niebur and Rudiger von der Heydt were awarded a new NIH research grant, in collaboration with Prof. Ralph Etienne-Cummings of the Department of Electrical and Chemical Engineering.  The grant, entitled “Neuronal mechanisms of perceptual organization in the primate visual system,” combines experimental and theoretical studies with neuromorphic engineering implementations to elucidate the interface between visual feature representations and attentive cognitive processes.

  • Nielsen Publishes in Neuron

     

    MBI Asst. Professor Kristina Nielsen published a research article in the journal Neuron.  In collaboration with researchers at the Salk Institute, Nielsen and her colleagues demonstrated a new organizing principle of how visual features are mapped efficiently in the primary visual cortex of macaque monkeys.

  • Niebur Lab Receives New Grant from ONR

     

    MBI Professor of Neuroscience Ernst Niebur has been awarded a new grant from the Office of Naval Research.  The title of the grant is “Bayesian approach for integrating spatial and temporal information during scene analysis.”
