call for papers: NeurIPS 2019 Workshop on ‘Context and Compositionality in biological and artificial neural systems’

by Alexander Huth

(Apologies for cross-post) NeurIPS 2019 - Workshop on ‘Context and Compositionality in biological and artificial neural systems’ Vancouver Convention Center, Vancouver CANADA Fri Dec 13th or Sat Dec 14th https://context-composition.github.io <https://context-composition.github.io/> Workshop abstract: The ability to integrate semantic information across narratives is fundamental to language understanding in both biological and artificial cognitive systems. There have been enormous strides in NLP and Machine Learning to develop architectures and techniques that effectively capture these effects. We have moved away from traditional bag-of-words approaches that ignore temporal ordering to RNNs, Temporal CNNs and Transformers that incorporate contextual information at varying timescales. While these architectures have lead to SoTA performance on many difficult language understanding tasks, it is unclear what representations these networks learn and how exactly they incorporate context. Interpreting these networks, systematically analyzing the advantages and disadvantages of different elements, such as gating or attention, and reflecting on the capacity of the networks across various timescales are open and important questions. On the biological side, recent work in neuroscience suggests that areas in the brain are organized into a temporal hierarchy in which different areas are not only sensitive to specific semantic information but also to the composition of information at different timescales. Computational neuroscience has moved in the direction of leveraging deep learning to gain insights about the brain. By answering questions on the underlying mechanisms and representational interpretability of these artificial networks, we can also expand our understanding of temporal hierarchies, memory and capacity effects in the brain. In this workshop we aim to bring together researchers from machine learning, NLP, and neuroscience to explore and discuss how computational models should effectively capture the multi-timescale, context-dependent effects that seem essential for processes such as language understanding. We believe that this will not only lead to a deeper understanding of biological language systems but also better artificial systems that can leverage these insights and understand language better. Call For Papers Paper submission deadline: Mon September 9th, 2019 22:00 PM UTC Decision Notification: Sun September 29th, 2019 22:00 PM UTC Submit at: https://cmt3.research.microsoft.com/CNTXTCOMP2019/ <https://cmt3.research.microsoft.com/CNTXTCOMP2019/> The site will start accepting submissions on August 7th.

Open Source Brain workshop 2019: Call for presentations/demos of open datasets and tools

by Gleeson, Padraig

[Apologies if you receive multiple copies of this due to cross-posting] The 2019 Open Source Brain workshop will be held in Alghero, Sardinia on 9-11th September 2019. There are a number of presentation slots still available for attendees to present open experimental data sets/databases/tools/simulators/libraries relevant to the goals of the meeting. Full details: http://www.opensourcebrain.org/docs/Help/Meetings#OSB_2019 Open Source Brain (http://www.opensourcebrain.org) is a platform for sharing and collaboratively developing models in computational neuroscience. Models of cells and circuits in standardised formats can be visualised, analysed and simulated through a standard web browser. A key driver for the development of this technology is to improve accessibility, scientific scrutiny, reproducibility and reuse of models of brain function. The platform is described in a recent paper in Neuron: https://www.cell.com/neuron/fulltext/S0896-6273(19)30444-1 The 2019 OSB Workshop will highlight the latest features of OSB and engage current and future users of the platform through invited talks, posters, hands on demonstrations, and user presentations. Since we are substantially expanding the functionality of Open Source Brain to enable sharing of standardized experimental data used to build and test the models of neurons and circuits, this year’s meeting will have two key themes: 1) Accessible sharing of cellular neuroscience data Through support for the Neurodata Without Borders (NWB) format, OSB will facilitate sharing of multiple types of experimental data used to constrain computational models, including electrophysiological recordings, Ca2+ fluorescence imaging, 2D, 3D and 4D imaging and behavioural data. Challenges, requirements and solutions to data standardization will be discussed. 2) Modelling cortical structures across scales Cortical networks are modelled at many scales from abstract representations of interacting populations (neural masses) to networks of biophysically and morphologically detailed cell models. NeuroML is being expanded to cover a greater range of these models, which will allow them to be shared and simulated on OSB, facilitating comparison of models and ideas between researchers. This ongoing work is taking place as part of the SIG on Standardised Representations of Network Structures<https://www.incf.org/activities/standards-and-best-practices/incf-special-i…>. Registration The registration fee for the meeting for 3 days will be £130. This will help cover organisation and speaker costs, meeting room hire, lunch, tea and coffee for 3 days and one workshop dinner. Please register here<https://onlinestore.ucl.ac.uk/conferences-and-events/faculty-of-life-scienc…>. Registration closes on 1st September 2019.

Postdoc position in modeling in vivo dendritic activity of cortical pyramidal neurons

by Erik De Schutter

The Computational Neuroscience Unit (https://groups.oist.jp/cnu) of Prof. Erik De Schutter at the Okinawa Institute of Science and Technology (OIST) is starting a project on modeling behaviorally relevant dendritic activity in layer 5 cortical pyramidal neurons. This will be a collaboration with Prof. Wen-Biao Gan at the New York University School of Medicine (https://med.nyu.edu/faculty/wenbiao-gan) who will provide in vivo data to constrain the models. The goal is to build quantitative models that capture how synaptic input drives dendritic calcium spiking in the apical tuft, how this activity is transmitted down the apical dendrite and changes somatic output as demonstrated, for example, in Cichon and Gan, Nature 2015. Candidates should have a PhD in (computational) neuroscience with good knowledge of dendritic physiology and experience in using the NEURON software to simulate compartmental models of neurons. Previous experience in modeling pyramidal neurons is a plus but not required. OIST is a young, fast-growing research-oriented interdisciplinary graduate university, located on the subtropical paradise island of Okinawa (https://www.visitokinawa.jp/) Despite being a newcomer in the academic world, OIST was recently ranked as #10 in the world on the Normalized Nature Index (https://www.natureindex.com/annual-tables/2019/institution/academic-normali…) It offers attractive financial and working conditions in an English language graduate university. Starting date any time before begin 2020. Send curriculum vitae, summary of research interests and experience, and the names of three referees to Prof. Erik De Schutter at erik(a)oist.jp

Recent research article

by Osva Velarde

Dear Colleagues, We are happy to share with you our work about the mechanisms of phase-amplitude cross frequency coupling (PAC) in models of biologically plausible neural networks. We think this work opens a new and valuable connection between theory of dynamical systems and the field of signal processing in neural networks and other biophysical systems. In particular, one of the proposed tools, the Time Locked Index (TLI), is suitable to efficiently quantify the harmonic content of experimental recordings. Hope you find this useful.
