    • Bayesian Model of Dynamic Image Stabilization in the Visual System 

      Burak, Yoram; Rokni, Uri; Meister, Markus; Sompolinsky, Haim I (Proceedings of the National Academy of Sciences, 2010)
      Humans can resolve the fine details of visual stimuli although the image projected on the retina is constantly drifting relative to the photoreceptor array. Here we demonstrate that the brain must take this drift into ...

    • Computing Complex Visual Features with Retinal Spike Times 

      Gütig, Robert; Gollisch, Tim; Sompolinsky, Haim I; Meister, Markus (Public Library of Science, 2013)
      Neurons in sensory systems can represent information not only by their firing rate, but also by the precise timing of individual spikes. For example, certain retinal ganglion cells, first identified in the salamander, ...

    • Dynamical Adaptation in Photoreceptors 

      Clark, Damon A.; Benichou, Raphael; Meister, Markus; Azeredo da Silveira, Rava (Public Library of Science, 2013)
      Adaptation is at the heart of sensation and nowhere is it more salient than in early visual processing. Light adaptation in photoreceptors is doubly dynamical: it depends upon the temporal structure of the input and it ...

    • Laminar Restriction of Retinal Ganglion Cell Dendrites and Axons: Subtype-Specific Developmental Patterns Revealed with Transgenic Markers 

      Kim, In-Jung; Zhang, Yifeng; Meister, Markus; Sanes, Joshua R. (Society for Neuroscience, 2010)
      Retinal ganglion cells (RGCs), which transfer information from the eye to the brain, are heterogeneous in structure and function, but developmental studies have generally treated them as a single group. Here, we investigate ...

    • LED Arrays as Cost Effective and Efficient Light Sources for Widefield Microscopy 

      Albeanu, Dinu F.; Soucy, Edward; Sato, Tomokazu F.; Meister, Markus; Murthy, Venkatesh (Public Library of Science, 2008)
      New developments in fluorophores as well as in detection methods have fueled the rapid growth of optical imaging in the life sciences. Commercial widefield microscopes generally use arc lamps, excitation/emission filters ...

    • Modeling Convergent ON and OFF Pathways in the Early Visual System 

      Gollisch, Tim; Meister, Markus (Springer-Verlag, 2008)
      For understanding the computation and function of single neurons in sensory systems, one needs to investigate how sensory stimuli are related to a neuron’s response and which biological mechanisms underlie this relationship. ...

    • Models of Visual Processing by the Retina 

      Real, Esteban (2013-02-11)
      The retina contains neural circuits that carry out computations as complex as object motion sensing, pattern recognition, and position anticipation. Models of some of these circuits have been recently discovered. A remarkable ...

    • A Neural Computation for Visual Acuity in the Presence of Eye Movements 

      Pitkow, Xaq; Sompolinsky, Haim; Meister, Markus (Public Library of Science, 2007)
      Humans can distinguish visual stimuli that differ by features the size of only a few photoreceptors. This is possible despite the incessant image motion due to fixational eye movements, which can be many times larger than ...

    • Precision and diversity in an odor map on the olfactory bulb 

      Soucy, Edward Richard; Albeanu, Dinu F.; Fantana, Antoniu L.; Murthy, Venkatesh N.; Meister, Markus (Springer Nature, 2009)
      We explored the map of odor space created by glomeruli on the olfactory bulb of both rat and mouse. Identified glomeruli could be matched across animals by their response profile to hundreds of odors. Their layout in ...

    • Rat Olfactory Bulb Mitral Cells Receive Sparse Glomerular Inputs 

      Fantana, Antoniu L.; Soucy, Edward R.; Meister, Markus (Elsevier, 2008)
      Center-surround receptive fields are a fundamental unit of brain organization. It has been proposed that olfactory bulb mitral cells exhibit this functional circuitry, with excitation from one glomerulus and inhibition ...

    • A Retinal Circuit That Computes Object Motion 

      Baccus, Stephen A.; Ölveczky, Bence P.; Manu, Mihai; Meister, Markus (Society for Neuroscience, 2008)
      Certain ganglion cells in the retina respond sensitively to differential motion between the receptive field center and surround, as produced by an object moving over the background, but are strongly suppressed by global ...

    • Retinal Ganglion Cells Can Rapidly Change Polarity from Off to On 

      Geffen, Maria Neimark; de Vries, Saskia E. J.; Meister, Markus (Public Library of Science, 2007)
      Retinal ganglion cells are commonly classified as On-center or Off-center depending on whether they are excited predominantly by brightening or dimming within the receptive field. Here we report that many ganglion cells ...

    • A Wireless Multi-Channel Neural Amplifier for Freely Moving Animals 

      Szuts, Tobi A; Fadeyev, Vitaliy; Kachiguine, Sergei; Sher, Alexander; Grivich, Matthew V; Agrochão, Margarida; Hottowy, Pawel; Dabrowski, Wladyslaw; Lubenov, Evgueniy V; Siapas, Athanassios G; Uchida, Naoshige; Litke, Alan M; Meister, Markus (Nature Publishing Group, 2011)
      Conventional neural recording systems restrict behavioral experiments to a flat indoor environment compatible with the cable that tethers the subject to recording instruments. To overcome these constraints, we developed a ...
