Free software helps data management in Neuroscience experiments

Research, Innovation and Dissemination Center for Neuromathematics (NeuroMat) – one of the research centers supported by FAPESP – has launched the first module of the free software Neuroscience Experiments System (NES), that helps organization, control and management of neurophysiological data from patients and experiments. Report by Karina Toledo, Agência FAPESP, 12/12/2014.

Powers of Hamilton cycles in pseudorandom graphs

Peter Allen, Julia Böttcher, Hiep Hàn, Yury Person, Yoshiharu Kohayakawa

We study the appearance of powers of Hamilton cycles in pseudorandom graphs, using the following comparatively weak pseudorandomness notion. A graph G is (ε,p,k,ℓ)-pseudorandom if for all disjoint X and Y⊂V(G) with |X|≥ε(pˆk)n and |Y|≥ε(pˆℓ)n we have e(X,Y)=(1±ε)p|X||Y|.

Spike sorting: Prof. Christophe Pouzat's 2014 training

Three videos on Prof. Christophe Pouzat's training on spike sorting, that occurred on November, 25-27, 2014, at the University of São Paulo. Streaming was made available by IPTV-USP. Videos in English.

NES - Neuroscience Experiments System

The Neuroscience Experiments System (NES) is an open-source tool being developed by CEPID NeuroMat that aims to assist neuroscience research laboratories in routine procedures for data collection. NES supports the reproducibility of experiments, enables comparison of data across studies, and keeps data provenance. In addition, it promotes standardized formats for experiments and analyses reporting.

Goals, challenges and horizons of spike sorting

How do we distinguish the activity of one or more neurons in a set of recorded neural activity? How do we assign spikes to different neurons? What mathematical, computational tools are available to sort spikes? These questions, among others, informed a three-day-long training on spike sorting that FAPESP's Research, Innovation and Dissemination Center for Neuromathematics (CEPID NeuroMat) hosted in São Paulo at the end of November (25-27), with Prof. Christian Pouzat, a researcher of the Applied Maths Laboratory of the Paris-Descartes University and a specialist in spike sorting
