[Comp-neuro] Convergence in Computational Neuroscience: Joint BrainScaleS CodeJam/NeuroML workshop

** Please accept our apologies for cross postings **

Dear all,

Announcing the Convergence in Computational Neuroscience 2012 workshop which will be held in Edinburgh from 12-16th March. The NeuroML Development Workshop and the BrainScaleS (previously FACETS) CodeJam have been two important workshops for developers of software tools for computational neuroscience for the past number of years, and this year they are being held over the same week.

The first 2 days will focus on the specifications & tool support for NeuroML, which has traditionally been focused on multicompartmental, conductance based neuronal models, but with version 2.0 is being extended to allow greater flexibility in creating new synapse, ion channel and abstract/point neuron models. Machine readable model definitions allow low level access to model parameters and equations, facilitating interoperability across simulators. Presentations and discussions will include updates on developments towards NeuroML 2, relationships to other modelling and neuroinformatics initiatives including COMBINE and the INCF, and talks on the latest developments in the Blue Brain Project, the Neural Tissue Simulator and the OpenWorm project.

More details for these days are here: http://www.neuroml.org/workshop2012

The remaining 3 days will have a similar format to previous CodeJams: presentations in the mornings with discussions & code sprints in the afternoon. The goal will be to catalyze open-source, collaborative software development in computational and systems neuroscience and neuroinformatics, by bringing together researchers, students and engineers to share ideas, present their work, and write code together. CodeJam #5 will focus on multi-compartmental modelling APIs, data analysis libraries, code generation and best practices in open source software development, with a slant towards the Python programming language. Speakers from a range of active areas in neuroscience-tool development have been invited; we will be hearing about the latest developments in NeuroDebian, Genesis 3.0, MOOSE, Topographica, OpenElectrophy, PyNN and many others. If you are starting a Ph.D. in computational neuroscience and want to get involved with the tool-building community, or are just interested in the state of the field, the CodeJam is a great opportunity to meet the developers behind the projects in an informal setting and discuss about ideas and future projects.

More details can be found here: http://neuralensemble.org/meetings/CodeJam5

Wednesday afternoon includes a mini workshop with the theme "Convergence, Interoperability and Reuse in Neuroscience Modelling Software", which seeks to develop a perspective on where the field is at and where we are going to.

This should be a very informative and useful week for anyone interested in learning about/sharing/integrating software tools for computational neuroscience.

There will be a limited number of bursaries available for travel to the meeting for UK based attendees through the UK Node of the INCF (http://www.neuroinformatics.org.uk/special-interest-groups-sigs/18-sig4). Contact p.gleeson@ucl.ac.uk for more details.

Abstract: The electrodynamics of action potentials represents the fundamental level where information is integrated and processed in neurons. The Hodgkin–Huxley model cannot explain the non-stereotyped spatial charge density dynamics that occur during action potential propagation. Revealed in experiments as spike directivity, the non-uniform charge density dynamics within neurons carry meaningful information and suggest that fragments of information regarding our memories are endogenously stored in structural patterns at a molecular level and are revealed only during spiking activity. The main conceptual idea is that under the influence of electric fields, efficient computation by interaction occurs between charge densities embedded within molecular structures and the transient developed flow of electrical charges. This process of computation underlying electrical interactions and molecular mechanisms at the subcellular level is dissimilar from spiking neuron models that a!
re completely devoid of physical interactions. Computation by interaction describes a more powerful continuous model of computation than the one that consists of discrete steps as represented in Turing machines.

Keywords: Physical theory; electric field; intraneuronal computation; spike stereotypy; subcellular signaling; neural code; Turing-machines

[Comp-neuro] "Dynamics of Memory: What is the Evidence?", Barcelona July 12-13, 2012. Satellite to FENS Forum

"Dynamics of memory: What is the evidence?"
Satellite event of FENS Forum
Barcelona, Spain, July 12-13, 2012
http://www.crm.cat/Activitats/Activitats/2011-2012/cmemory/web-cmemory/default.htm

CALL FOR ABSTRACTS to FENS Forum, DEADLINE: February 5, 2012 !!

CALL FOR ABSTRACTS to the satellite workshop, deadline: June 30, 2012


This workshop is organized as a satellite event of the FENS Forum in
Barcelona (http://fens2012.neurosciences.asso.fr/), the largest
international neuroscience meeting in Europe. The 2-day workshop will
take place immediately before the FENS forum in Barcelona (Spain) and it
will bring together leading experimental and theoretical neuroscientists
to discuss about experimental validations of mechanistic theories for
memory.

The overall scientific goal of the workshop is to discuss experimental
approaches that evaluate and assess different proposed theoretical
frameworks comprising mechanistic explanations for how memories are
stored, retrieved and maintained in the brain. Several reasons make this
the right time to bring together theoreticians and experimentalists to
discuss the dynamics of memory. First, the existence of a diversity of
experimental techniques which are capable of providing evidence
sufficiently precise so as to discard proposed theoretical alternatives.
Also, the progressive infiltration of theoretical ideas into
experimental journals and forums has made it possible for
experimentalists to become familiar and interested in quantitative
approaches which, until recently, were only discussed among
theoreticians. Because of this, we feel like this conference will be of
great interest to systems neuroscientists, both those using experimental
as well as theoretical approaches.

"Dynamics of memory: What is the evidence?" will be organized by the
Center for Mathematical Research (CRM) in a beautiful 17th century
building in the old city of Barcelona, minutes away from the Rambla
boulevard. Thirty-minute bus connection to Barcelona-El Prat airport is
within a 5 minute walk of the workshop venue. This central location
offers a broad range of accommodation, food and entertainment options
within walking distance. Registration for this event will open shortly
in
http://www.crm.cat/Activitats/Activitats/2011-2012/cmemory/web-cmemory/default.htm

Poster presentations will complement oral presentations by the following
confirmed invited speakers:

Moshe Abeles, Hebrew University, Israel
