NeuroMat data-management tools to help treating neurological injuries

Researchers from the Federal University of Rio de Janeiro (UFRJ) and the University of São Paulo (USP) have collaborated to develop open-access, data-sharing computational tools, that could lead to progress in understanding and treating neurological lesions, especially damages of a network of nerves called brachial plexus.

Biological Motion Coding in the Brain: Analysis of Visually Driven EEG Functional Networks

Fraiman, D. ; Saunier, G. ; Martins, E. F. and Vargas, C. D. - Herein, we address the time evolution of brain functional networks computed from electroencephalographic activity driven by visual stimuli. We describe how these functional network signatures change in fast scale when confronted with point-light display stimuli depicting biological motion (BM) as opposed to scrambled motion (SM).

Graph analysis of dream reports is especially informative about psychosis

Mota, N. B. ; Furtado, R. ; Maia, P. P. C. ; Copelli, M. and Ribeiro, S. - Early psychiatry investigated dreams to understand psychopathologies. Contemporary psychiatry, which neglects dreams, has been criticized for lack of objectivity. In search of quantitative insight into the structure of psychotic speech, we investigated speech graph attributes (SGA) in patients with schizophrenia, bipolar disorder type I, and non-psychotic controls as they reported waking and dream contents.

Infinite Systems of Interacting Chains with Memory of Variable Length—A Stochastic Model for Biological Neural Nets

Galves, A. and Löcherbach, E. - We consider a new class of non Markovian processes with a countable number of interacting components. At each time unit, each component can take two values, indicating if it has a spike or not at this precise moment.

Position for working with digital signal processing

The recently established Research, Innovation and Dissemination Center on Neuromathematics (NeuroMat), hosted by the University of São Paulo, Brazil, and funded by FAPESP (São Paulo Research Foundation) is offering technical training scholarships for Computer Science/Engineering professionals interested in applying their Computing experience on a world class scientific project.
