“Advances and challenges in large-scale neuronal recordings from the primate brain” (Beth Buffalo):

While it has long been recognized that medial temporal lobe structures are important for memory formation, studies in rodents have also identified exquisite spatial representations in these regions in the form of place cells in the hippocampus and grid cells in the entorhinal cortex.  Spatial representations entail neural activity that is observed when the rat is in a given physical location, and these representations are thought to form the basis of navigation via path integration.  However, our understanding of similar representations in the primate brain is limited. In this talk, I will discuss ongoing work from my laboratory involving chronic, large-scale recordings throughout the primate hippocampus while monkeys navigate through virtual environments, with the overarching goal of furthering our understanding of the function of the hippocampus and the nature of the cognitive map.

“Electromagnetics Meets Biology” (Matt Reynolds):

This talk will demystify some of the engineering challenges faced by designers of wireless devices that must function in and around animals. Motivated by example bio/electronic systems ranging from a tiny wireless backpack for neural recording in flying dragonflies, to a wireless real-time neural recording uplink for neuroscience research in non-human primates, I will discuss key questions such as, “How much power can we safely transfer through biological tissue?” and “How fast can we get data out of the brain?” I will explain the design process for on-body and in-body power and data communication networks, and present some ideas for the cyborgs of the future.
