      Biological systems by default involve complex components with complex relationships. To decipher how biological systems work, we assume that one needs to integrate information over multiple levels of complexity. The songbird ...
    • A Functionally Conserved Gene Regulatory Network Module Governing Olfactory Neuron Diversity. 

      Li, Q; Barish, S; Okuwa, S; Maciejewski, A; Brandt, AT; Reinhold, D; Jones, CD; ... (8 authors) (PLoS Genet, 2016-01)
      Sensory neuron diversity is required for organisms to decipher complex environmental cues. In Drosophila, the olfactory environment is detected by 50 different olfactory receptor neuron (ORN) classes that are clustered in ...
    • A Three-Threshold Learning Rule Approaches the Maximal Capacity of Recurrent Neural Networks. 

      Alemi, A; Baldassi, C; Brunel, Nicolas; Zecchina, R (PLoS Comput Biol, 2015-08)
      Understanding the theoretical foundations of how memories are encoded and retrieved in neural populations is a central challenge in neuroscience. A popular theoretical scenario for modeling memory function is the attractor ...
    • Altered resting-state functional connectivity of basolateral and centromedial amygdala complexes in posttraumatic stress disorder. 

      Brown, VM; Gold, AL; Haswell, CC; LaBar, Kevin S; McCarthy, G; Mid-Atlantic MIRECC Workgroup; Morey, Rajendra A (Neuropsychopharmacology, 2014-01)
      The amygdala is a major structure that orchestrates defensive reactions to environmental threats and is implicated in hypervigilance and symptoms of heightened arousal in posttraumatic stress disorder (PTSD). The basolateral ...
    • Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study. 

      Browndyke, Jeffrey Nicholas; Harshbarger, Todd Brenson; Klein, SM; Madden, David Joseph; Melton, MS; Nielsen, Karen C (Anesthesiology, 2016-08)
      BACKGROUND: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity ...
    • 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 circuits in the primate brain. 

      Crapse, Trinity; Sommer, Marc A (Curr Opin Neurobiol, 2008-12)
      Movements are necessary to engage the world, but every movement results in sensorimotor ambiguity. Self-movements cause changes to sensory inflow as well as changes in the positions of objects relative to motor effectors ...
    • Distinct and atypical intrinsic and extrinsic cell death pathways between photoreceptor cell types upon specific ablation of Ranbp2 in cone photoreceptors. 

      Cho, K-I; Haque, M; Wang, J; Yu, M; Hao, Y; Qiu, S; Pillai, ICL; ... (9 authors) (PLoS Genet, 2013-06)
      Non-autonomous cell-death is a cardinal feature of the disintegration of neural networks in neurodegenerative diseases, but the molecular bases of this process are poorly understood. The neural retina comprises a mosaic ...
    • Emotion-attention network interactions during a visual oddball task. 

      Dean, HL; Dillon, DG; Fichtenholtz, Harlan M; LaBar, Kevin S; McCarthy, G; Yamasaki, H (Brain Res Cogn Brain Res, 2004-06)
      Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used ...
    • Functional parcellation of attentional control regions of the brain. 

      Dale, AM; Fichtenholtz, Harlan M; Hazlett, CJ; Song, AW; Weissman, DH; Woldorff, Marty G (J Cogn Neurosci, 2004-01)
      Recently, a number of investigators have examined the neural loci of psychological processes enabling the control of visual spatial attention using cued-attention paradigms in combination with event-related functional magnetic ...
    • Memory capacity of networks with stochastic binary synapses. 

      Dubreuil, AM; Amit, Y; Brunel, Nicolas (PLoS Comput Biol, 2014-08)
      In standard attractor neural network models, specific patterns of activity are stored in the synaptic matrix, so that they become fixed point attractors of the network dynamics. The storage capacity of such networks has ...
    • Microcircuits for attention. 

      Sommer, Marc A (Neuron, 2007-07-05)
      Researchers who study the neuronal basis of cognition face a paradox. If they extract the brain, its cognitive functions cannot be assessed. On the other hand, the brain's microcircuits are difficult to study in the intact ...
    • Neural networks supporting autobiographical memory retrieval in posttraumatic stress disorder. 

      Kragel, Philip A; Rubin, David C; St Jacques, PL (Cogn Affect Behav Neurosci, 2013-09)
      Posttraumatic stress disorder (PTSD) affects the functional recruitment and connectivity between neural regions during autobiographical memory (AM) retrieval that overlap with default and control networks. Whether such univariate ...
    • Neuronal Adaptation: Tired Neurons or Wired Networks? 

      Mayo, Patrick; Smith, Matthew A (Trends in neurosciences, 2017-03)
      Neuronal adaptation - time-dependent modulation of sensory responses following sequential stimuli - is thought to be a consequence of synaptic plasticity. But recent, empirically-grounded, modeling by Quiroga and colleagues ...
    • Prefrontal contributions to relational encoding in amnestic mild cognitive impairment.

      Relational memory declines are well documented as an early marker for amnestic mild cognitive impairment (aMCI). Episodic memory formation relies on relational processing supported by two mnemonic mechanisms, generation ...
    • Presynaptic Inputs to Any CNS Projection Neuron Identified by Dual Recombinant Virus Infection. 

      Bráz, JM; Wang, Fan; Basbaum, AI (PLoS One, 2015)
      Although neuroanatomical tracing studies have defined the origin and targets of major projection neurons (PN) of the central nervous system (CNS), there is much less information about the circuits that influence these neurons. ...
    • The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task. 

      Appelbaum, Lawrence Gregory; Boehler, CN; Chen, LC; Krebs, Ruth M; Woldorff, Marty G (PLoS One, 2011)
      Inhibitory motor control is a core function of cognitive control. Evidence from diverse experimental approaches has linked this function to a mostly right-lateralized network of cortical and subcortical areas, wherein a ...
