    • Coherence potentials: loss-less, all-or-none network events in the cortex. 

      Lebedev, Mikhail A; Nicolelis, Miguel A; Plenz, D; Thiagarajan, TC (PLoS Biol, 2010-01-12)
      Transient associations among neurons are thought to underlie memory and behavior. However, little is known about how such associations occur or how they can be identified. Here we recorded ongoing local field potential (LFP) ...
    • Computational inference of neural information flow networks. 

      Hartemink, Alexander J; Jarvis, Erich David; Smith, VA; Smulders, TV; Yu, J (PLoS Comput Biol, 2006-11-24)
      Determining how information flows along anatomical brain pathways is a fundamental requirement for understanding how animals perceive their environments, learn, and behave. Attempts to reveal such neural information flow ...
    • Corollary discharge across the animal kingdom. 

      Crapse, Trinity; Sommer, Marc A (Nat Rev Neurosci, 2008-08)
      Our movements can hinder our ability to sense the world. Movements can induce sensory input (for example, when you hit something) that is indistinguishable from the input that is caused by external agents (for example, when ...
    • Correlated firing among major ganglion cell types in primate retina. 

      Field, Greg; Greschner, Martin; Shlens, Jonathon; Bakolitsa, Constantina; Gauthier, Jeffrey L; Jepson, Lauren H; Sher, Alexander; ... (9 authors) (The Journal of physiology, 2011-01)
      Retinal ganglion cells exhibit substantial correlated firing: a tendency to fire nearly synchronously at rates different from those expected by chance. These correlations suggest that network interactions significantly shape ...
    • Differential expression of glutamate receptors in avian neural pathways for learned vocalization. 

      Hagiwara, M; Jarvis, Erich David; Sakaguchi, H; Wada, K (J Comp Neurol, 2004-08-09)
      Learned vocalization, the substrate for human language, is a rare trait. It is found in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These three groups contain cerebral vocal nuclei for learned ...
    • For whom the bird sings: context-dependent gene expression. 

      Grossman, Matthew R; Jarvis, Erich David; Nottebohm, F; Ramos, JA; Scharff, C (Neuron, 1998-10)
      Male zebra finches display two song behaviors: directed and undirected singing. The two differ little in the vocalizations produced but greatly in how song is delivered. "Directed" song is usually accompanied by a courtship ...
    • Frontal eye field sends delay activity related to movement, memory, and vision to the superior colliculus. 

      Sommer, Marc A; Wurtz, RH (J Neurophysiol, 2001-04)
      Many neurons within prefrontal cortex exhibit a tonic discharge between visual stimulation and motor response. This delay activity may contribute to movement, memory, and vision. We studied delay activity sent from the frontal ...
    • Spike avalanches exhibit universal dynamics across the sleep-wake cycle. 

      Belchior, H; Caixeta, F; Chialvo, DR; Copelli, M; Nicolelis, Miguel A; Ribeiro, S; Ribeiro, TL (PLoS One, 2010-11-30)
      BACKGROUND: Scale-invariant neuronal avalanches have been observed in cell cultures and slices as well as anesthetized and awake brains, suggesting that the brain operates near criticality, i.e. within a narrow margin between ...
