Robert H. Wurtz "Brain Circuits for Stable Visual Perception"
Robert H. Wurtz: Brain Circuits for Stable Visual Perception. Vision Sciences Society Annual Meeting, Keynote 2009. Abstract: In the 19th century von Helmholtz detailed the need for signals in the brain that provide information about each impending eye movement. He argued that such signals coul...

Carla Shatz "Releasing the Brake on Ocular Dominance Plasticity"
Carla Shartz: Releasing the Brake on Ocular Dominance Plasticity. Vision Sciences Society Annual Meeting, Keynote 2010. Connections in adult visual system are highly precise, but they do not start out that way. Precision emerges during critical periods of development as synaptic connections rem...

Daniel Wolpert "Probabilistic Models of Human Sensorimotor Control"
Daniel Wolpert: Probabilistic Models of Human Sensorimotor Control. Vision Sciences Society Annual Meeting, Keynote 2011. The effortless ease with which humans move our arms, our eyes, even our lips when we speak masks the true complexity of the control processes involved. This is evident when ...

Ranulfo Romo "Conversion of sensory signals into perceptual decisions"
Ranulfo Romo: Conversion of sensory signals into perceptual decisions. Vision Sciences Society Annual Meeting, Keynote 2012. Most perceptual tasks require sequential steps to be carried out. This must be the case, for example, when subjects discriminate the difference in frequency between two m...

Larry Abbott "The Interaction of Evoked and Spontaneous Activity in Visual Processing"
Larry Abbott. VSS Keynote Address 2007: The Interaction of Evoked and Spontaneous Activity in Visual Processing. In vivo recordings from primary visual cortex reveal that spontaneous background activity can be as complex as activity evoked by visual stimuli. Embedding visually evoked responses in...

Edward Callaway "Unraveling fine-scale and cell-type specificity of visual cortical circuits"
Edward Callaway. VSS Keynote Address 2008: Unraveling fine-scale and cell-type specificity of visual cortical circuits. We have studied primary visual cortex to better understand how neural circuits give rise to perception. We have found that cortical circuits are extremely precise, such that dif...

Dora Angelaki "Vision Sciences Society Annual Meeting 2013: Optimal Integration of Sensory Evidence: Building Blocks and Canonical Computations"
A fundamental aspect of our sensory experience is that information from different modalities is often seamlessly integrated into a uniļ¬ed percept. Recent computational and behavioral studies have shown that humans combine sensory cues according to a statistically optimal scheme derived from Bayes...

Bruno Olshausen "VSS 2015 Keynote: Vision in Brains and Machines"
Vision Sciences Society Keynote Lecture 2015: Vision in Brains and Machines The past twenty years have seen important advances in both our understanding of visual representation in brains and in the development of algorithms that enable machines to 'see.' What is perhaps most remarkable about th...
