Methods in the Frequency Following Response, 6-7 June 2017

The Frequency Following Response (FFR) is an EEG-based measure of the scalp-recorded brainstem response to speech stimuli. In broad terms, it registers neural phase-locking to time-varying F0 and spectral characteristics of the speech signal, thus providing a robust representation of perceived changes in pitch. During a two-day workshop, the invited speaker, Bharath Chandrasekaran (University of Texas at Austin), will provide participants with the technical and theoretical background necessary to collect and analyze FFR data using on-site EEG capabilities (Biosemi Two). A roundtable discussion on the second day of the workshop will explore how FFR may be used to address the neural basis of intonation and its associated linguistic representations.
Dates: 6 – 7 June 2017, 9:30 – 17:30 (detailed program to follow)
Location: Salle A003, Laboratoire Parole et Langage, Aix-en-Provence
The workshop is open to all researchers, doctoral students, and postdocs from BLRI-affiliated institutions.
Registration is free but obligatory by going to this link. Space is limited to 25 participants. Lunch will be provided on both days of the workshop.
This workshop, organized by James Sneed German, is co-sponsored by the Brain & Language Research Institute and by a grant from the A*MIDEX Foundation (SIRL, n° ANR-11-IDEX-0001-02).

Training course
9h30 - 17h FRUMAM (3rd floor)
Aix-Marseille Université
The training will take place in the FRUMAM third floor seminary room on the campus of Aix-Marseille University.
Functional brain data are often represented as a network or graph to model the brain regions as nodes and the connections as edges. A graph is an abstract object to represent multivariate data on a simple map of connections. In this tutorial, I will give a short introduction on the modelling of data as a network, with references. In a first part, I will describe precisely how to construct the connectivity networks using brain data recordings. Robustness and reproducibility will be discussed precisely. In a second part, I will describe tools to compare and classify the networks based on statistical tests or learning methods. Finally, I will conclude with a practical example from the clinical data on coma patients.
