Dynamic Computation in Visual Thalamocortical Networks

Roy Moyal, Shimon Edelman
2019 Entropy  
To conclude the review, we begin to integrate this perspective with longstanding theories of consciousness and cognition.  ...  Contemporary neurodynamical frameworks, such as coordination dynamics and winnerless competition, posit that the brain approximates symbolic computation by transitioning between metastable attractive states  ...  Of particular empirical interest is the concept of intrinsic ignition, defined by Deco and Kringelbach [276] as the capacity of a particular network element to "propagate neuronal activity to other regions  ...

Temporal aspects of neural coding in the retina and lateral geniculate

Jonathan Victor
1999 Network  
The early stages of visual processing provide excellent models for the study of how information is represented in, and processed by, the activity of neurons.  ...  The broad theme that emerges from a review of experimental data is that each stage of visual processing is accompanied by new features, including adaptive filtering, feedback, rectification and spike generation  ...  The author also expresses appreciation to the many investigators who have provided preprints and reprints of their work.  ...

Sensory coding accuracy and perceptual performance are improved during the desynchronized cortical state

Charles B. Beaman, Sarah L. Eagleman, Valentin Dragoi
2017 Nature Communications  
Cortical activity changes continuously during the course of the day.  ...  These fluctuations are local and control the trial variability in population coding accuracy and behavioral performance in a discrimination task.  ...  We decoded the neural activity by implementing a linear classifier which fits a multivariate normal density with a pooled estimate of covariance using the MATLAB function, classify. 50% of the data was  ...

Tony J. Prescott, Fernando M. Montes González, Kevin Gurney, Mark D. Humphries, Peter Redgrave
2006 Neural Networks  
Our results demonstrate effective action selection by the embedded model under a wide range of sensory and motivational conditions.  ...  A strong test of this hypothesis is to require a computational model of the basal ganglia to generate integrated selection sequences in an autonomous agent, we therefore describe a robot architecture into  ...  Acknowledgements The authors wish to acknowledge the assistance of Jonathan Chambers, Ric Wood, Michael Port, Andy Ham, and Olivier Michel, and the support of the UK Engineering and Physical Sciences Research  ...

How laminar frontal cortex and basal ganglia circuits interact to control planned and reactive saccades

Joshua W. Brown, Daniel Bullock, Stephen Grossberg
2004 Neural Networks  
The model predicts how action planning or priming (in cortical layers III and VI) is dissociated from execution (in layer V), how a cue may serve either as a movement target or as a discriminative cue  ...  A neural model whose cortical component represents the frontal eye fields captures these interacting circuits.  ...  Taken together, these data suggest a hierarchy of control, such that visual inputs to the SC dominate by default, but the frontal cortex can assume control of the SC when simple reactive eye movements  ...
