    • Neural Circuit Mechanisms Underlying Cognition in Rats 

      Brody, Carlos (2019-03-11)
      I will describe studies of the neural bases of cognitive processes. Rodents, mostly rats, are trained to perform behaviors that lend themselves to quantitative modeling that can help identify and assess specific cognitive ...
    • The Neural Circuits Underlying Short-term Memory 

      Svoboda, Karel (2017-10-02)
      Our goal is to uncover the principles by which cortical circuits perform fundamental computations, from perception to action. Cortex is parcellated into areas with distinct function and local circuits. Cortical areas ...
    • Neural Codes and Maps in Whisker Somatosensory Cortex 

      Feldman, Daniel (2018-10-15)
      How do neural circuits in the brain’s cerebral cortex mediate sensation, memory, voluntary movement, and higher functions, and how does this break down in neurological disease? Our lab seeks to answer these questions by ...
    • Neural coding of sound in the ascending and descending auditory pathways 

      Polley, Daniel B. (2021-02-08)
      Our perception of music, speech and the surrounding soundscape all originate from patterns of vibrations in the cochlea. To encode these high-speed vibrations, evolutionary pressures designed an exquisite hydro/electro/mechanical ...
    • Neural Decoding and Control of Multiscale Brain Networks: From Motor to Mood 

      Shanechi, Maryam (2019-11-11)
      In this talk, I first discuss our recent work on modeling, decoding, and controlling multisite human brain activity underlying mood states. I present a multiscale dynamical modeling framework that allows us, for the first ...
    • Neural Dynamics of the Primate Attention Network 

      Kastner, Sabine (2017-01-30)
      The selection of information from our cluttered sensory environments is one of the most fundamental cognitive operations performed by the primate brain. In the visual domain, the selection process is thought to be mediated ...
    • Neural Mechanisms of Movement Precision 

      Person, Abigail (2019-09-09)
      How the brain makes movements fast, smooth and accurate has remained a mystery. In this talk I will discuss our studies identifying predictive, adaptively scaled activity in a cerebellar output structure that causally ...
    • The neurobiology of decision making: The best-laid plans of mice and primates 

      Shadlen, Michael N. (2020-10-12)
      Many decisions arise through an accumulation of evidence to a terminating threshold. The process provides a unified account of the choice (e.g., accuracy) and the amount of time taken to complete it. It also provides a ...
    • New Cortex. Who dis(inhibition)? 

      Doiron, Brent (2018-11-26)
      My general research program seeks to identify how single neurons and networks of neurons code information about relevant inputs. Using a combination of nonlinear systems theory, stochastic differential equations, and ...
    • Perturbation-imaging Approaches to Study Functional Contributions of Cortical Activity to Human Movement 

      Borich, Michael (2019-09-30)
      The ability to learn and produce skilled movements is required for humans to successfully engage with each other and their environment. A principal role of the brain is to guide current, and plan future, movements based ...
    • Principles of Motor Control 

      Chiel, Hillel J. (2017-01-23)
      How does the nervous system control behavior? To answer this question requires an understanding of neural circuitry, biomechanics, and behavior. To address this question, we have studied an experimentally tractable ...
    • Rethinking Recovery and Rehabilitation after Stroke 

      Krakauer, John (2017-03-06)
      There are critical differences in the potential for rehabilitation of impairment early and late after stroke. Early after stroke the proportional recovery rule for spontaneous biological recovery applies, as does the idea ...
    • Scene Recognition: How and Why? 

      Dilks, Daniel D. (2017-12-04)
      Our ability to perceive the visual environment is remarkable: we can recognize a place or “scene” (e.g., a kitchen, a beach, Georgia Tech) within a fraction of a second – even if we have never seen that particular place ...
    • The Self-Repairing Brain: Mechanisms Underlying Plasticity in Sensory Pathways? 

      Pallas, Sarah (2017-10-30)
      Research in the Pallas lab is aimed at understanding the cellular and molecular mechanisms underlying development and plasticity of sensory pathways in the brain. Our approach is to alter normal developmental programs, ...
    • Simultaneous Representation of Sensory and Mnemonic Information in Human Visual Cortex 

      Serences, John (2019-02-18)
      Navigating through complex environments requires keeping relevant information in mind, or in working memory, while simultaneously processing new sensory inputs. For example, when frantically looking for your car keys in ...
    • Social Information Processing and Learning in Rodents 

      Liu, Robert (2017-11-27)
      There is an increasing appreciation that mental health disorders often include social-specific deficits, motivating research into the neurophysiological mechanisms that underlie natural, social behaviors in mammals. ...
    • Spontaneous travelling cortical waves gate perception in behaving primates 

      Reynolds, John (2020-11-16)
      Perceptual sensitivity varies from moment to moment. One potential source of this variability is spontaneous fluctuations in cortical activity that can travel as waves. Spontaneous travelling waves have been reported during ...
    • Straighten Up and Fly Right: Navigation and Motor Control in Fruit Flies 

      Dickinson, Michael H. (2020-02-03)
      Over 400 million years ago, a group of tiny six-legged creatures evolved the ability to fly—an event that fundamentally transformed our planet. Equipped with the ability to fly, insects underwent an extraordinary radiation ...
    • A Systems Neuroscience Approach to Motor Recovery 

      Ganguly, Karunesh (2018-02-05)
      It is commonly hypothesized that restoration of normal neural dynamics in the injured brain can improve function. However, we lack a precise neurophysiological framework for such an approach. Here we show that low-frequency ...
