In Frontiers in Neuroinformatics, researchers explain how simulating biological neuronal networks is a core method of research in computational neuroscience. A full specification of such a network model includes a description of the dynamics and state changes of neurons and synapses, as well as the synaptic connectivity patterns and the initial values of all parameters.
In Frontiers in Neuroinformatics, researchers present a detailed account on the methods behind the ISC Toolbox, the implementation of the toolbox and demonstrate the possible use of the toolbox by summarizing selected example applications. They also report the computation time experiments both using a single desktop computer and two grid environments demonstrating that parallelization effectively reduces the computing time.
The first seminar in the 2014 INCF Seminar series: Karlheinz Meier, Professor at the Ruprecht Karl University of Heidelberg and Co-director of the Human Brain Project, will give a seminar entitled From Ions to Electrons - Physical Models of Brain Circuits, February 6th at 15:00 in the Lennart Nilsson lecture hall, at Karolinska Institutet (Stockholm, Sweden)
In Brain and Behavior, Maryann Martone encourages all who publish in Brain and Behavior to make their data available. For example, Brain and Behavior will now allow researchers to publish data papers. Data papers will allow researchers to publish a paper describing a data set that will be deposited within a certified data repository.
In Frontiers in Neuroinformatics, members of the INCF UK Node describe morphforge, a toolbox for simulating small networks of biologically detailed neurons in Python that will allow scientists to quickly build simulations of multicompartmental model neurons for research and serve as a platform for further tool development.
Co-hosted by the Allen Institute for Brain Science and the Computational Neuroscience Program at the University of Washington and directed by Drs. Christof Koch and Adrienne Fairhall, this intensive two-week, interdisciplinary course aims to give advanced students in neuroscience, biology, physics, engineering and computer science a rapid introduction to the current state of understanding of the neurobiology of sensory processing, including anatomy, physiology and neural coding.
In PLOS Computational Biology, members of the INCF Swiss and UK Node suggest ways in which current software development practice in computational neuroscience can be improved and propose checklists to help developers, reviewers, and scientists to assess the quality of software and whether particular pieces of software are ready for use in research.
Comparing local neural structures across large sets of examples is crucial when studying gene functions, and their effect in the Drosophila brain. In this paper, researchers propose and evaluate an image-based retrieval method for neurons, relying on local appearance, which can cope with spatial variability across the population.
In Frontiers in Neuroinformatics, members of the Polish, Norwegian and Swedish INCF Node describe LFPy, an open source Python package for numerical simulations of extracellular potentials.
Patterns of distributed brain activity are thought to underlie virtually all aspects of cognition and behavior. In this paper, researchers explore the degree to which it is possible to predict such functional patterns from the network of anatomical connections that link brain regions and shed light on the important role of anatomical networks and communication processes in shaping the brain’s functional activity.
This Frontiers in Neurogenomics Research Topic aims to be an online extension of the INCF Short Course on Neuroinformatics, Neurogenomics and Brain Disease. In this workshop, six groups of "next-gen" neuroscientists evaluated how key online data resources can be exploited to address important topics at the interface of neuroscience, genetics, and genomics. Inspired by the concept of a “speed coding jamboree”, the groups took part in a “speed neuroinformatics analysis jamboree” over a one-week period and produced draft papers as an initial output.
The INCF Training Committee cordially invites organizers of neuroinformatics-related courses to apply for co-funding for courses taking place in 2015.
