UWIN’s March seminar features a pair of short talks by Beth Buffalo and Matt Reynolds:
- “Advances and challenges in large-scale neuronal recordings from the primate brain”: Beth Buffalo, Professor, Department of Physiology and Biophysics, University of Washington
- “Electromagnetics Meets Biology”: Matt Reynolds, Associate Professor, Departments of Electrical Engineering and Computer Science and Engineering, University of Washington
The seminar is on Wednesday, March 8th, at 3:30pm in Husky Union Building (HUB) 337. Refreshments will be served prior to the talks.
“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.

UWIN’s December seminar features a talk by visiting speaker Matt Smear from the University of Oregon’s Department of Psychology and Institute of Neuroscience.
His talk is entitled: “Concentration change detectors in the olfactory bulb”
The seminar is on Wednesday, December 14th, at 3:30pm in Health Sciences Building G-328. Refreshments will be served prior to the talk across the hall in room G-317. Click here for a map of the Health Sciences Building.
Abstract: Brains operate in dynamic environments. Sensory systems prioritize stimulus changes, as evidenced by the many neuronal mechanisms devoted to comparing sensory inputs across time. My lab has been studying an ethologically relevant form of delayed comparison: detection of odor concentration changes across sequential sniffs (hereafter called ΔCt). Rodents use ΔCt as a guidance cue during olfactory navigation, a behavior that is crucial to their livelihood. To study ΔCt processing, we have developed an odor stimulation system which can change odor concentration with unprecedented speed. Combining this system with electrophysiological recordings in awake head-fixed mice, we have discovered that a subset of neurons in the olfactory bulb are ΔCt sensitive – they strongly modulate their firing rate when odor concentration changes. By studying this system, we hope to uncover fundamental principles underlying our ability to follow along as the external world changes.

UWIN postdoctoral fellow Eatai Roth, working in the lab of UWIN Co-director Tom Daniel, recently published a paper in Proceedings of the National Academy of Sciences on how multiple types of sensory information are used by hawkmoths to govern flight behavior. The paper, entitled “Integration of parallel mechanosensory and visual pathways resolved through sensory conflict”, describes work that investigated how moths combine sensory cues to follow the motion of wavering flowers while feeding.
While hovering in front of a flower, a feeding moth receives information about how the flower is moving from two sensory modalities: visual information from the eye and mechanosensory information from the proboscis in contact with the flower. By building a two-part artificial flower that allows for independent manipulation of visual and mechanosensory cues, Roth et al. disentangled the contribution of each sensory modality to the moth’s flower-following behavior. They found that the brain linearly sums information from the visual and mechanosensory domains to maintain this behavior. They further demonstrated that either sensory modality alone would be sufficient for this behavior, and this redundancy makes the behavior robust to changes in the availability of sensory information.
This work provides a better understanding of how multiple sensory modalities are used in nature to govern complex behaviors, and connects with the mission of the Air Force Center of Excellence on Nature-Inspired Flight Technologies and Ideas (NIFTI).
This research was also featured in a UW Today article, “Tricking moths into revealing the computational underpinnings of sensory integration”.
