June 2018: MEG data from 14 typically-developing children show that neuronal oscillations in the right auditory cortex in the theta band (4-7 Hz) phase-lock to speech amplitude envelope at a normal syllabic rate. For fast (naturally-accelerated) syllabic rate, cortico-acoustic coherence is seen in the left premotor cortex (Guiraud et al., in prep), in agreement with the role of this region, which is part of the dorsal stream, in degraded speech perception.

January 2018: Article in Plos One on the deficit to process fast rate speech in children with Specific Language Impairment (cf. Publications).

15th december 2017: Hélène Guiraud defended her PhD thesis on the "Symphony of brain oscillations during speech perception: Behavioral and MEG studies in typically-developing children and children with Specific Language Impairment. Congratulations!

July 2016: First results of the MEG studies in adults and children. MEG data have been recorded in 24 healthy adults (V. Boulenger & H. Laaksonen) and 11 healthy children (H. Guiraud), data are still being acquired in children including SLI children. Results in adults provide evidence for entrainment of neuronal oscillations to the amplitude envelope of the speech signal in frequency windows centered on the syllabic rate (5-7 Hz for normal speech and 8-10 Hz for fast speech). Interestingly, acoustic-cortical coupling is also observed in the pitch (F0) frequency band. In children, results also suggest coherence between cortical oscillations and speech signals but only for normal rate speech. The results have been presented in several conferences and two articles are currently in preparation (Guiraud et al., Hincapié et al.).

05/07/2013: Bravo! Hélène Guiraud has brilliantly defended her Master 2 thesis in Neuropsychology on fast speech perception in healthy children and children with verbal dyspraxia. She also obtained a PhD grant from the Labex ASLAN. We congratulate her warmly and are very pleased that she'll work with us for the next 3 years!

	24/04/2013: MEG piloting. First MEG pilots have started at the MEG department of the CERMEP. We will need volunteers anytime soon!
01/02/2013: Welcome to Hannu! Hannu Laaksonen has arrived from Finland to start his post-doc on the ODYSSEE project. Hannu will mainly analyze MEG data on fast speech processing.

June 2016: Behavioral results for fast speech perception in SLI children. The behavioral study carried out by Hélène Guiraud and including 17 SLI children and 17 healthy controls, reveals a deficit to process fast speech, either naturally or artificially accelerated, in SLI children. We interpret these findings as reflecting an impairment to adjust to the rhythm of the external acoustic signal, possibly underlain for an oscillatory dysfinction (Guiraud et al., submitted).

October 2015: Ana-Sofia Hincapié, a PhD student working with Karim Jerbi, joined the ODYSSEE project. Ana-Sofia (Psychology Department, University of Montreal, Quebec, Canada & Pontificia Universidad Católica de Chile, Santiago de Chile, Chile) is doing a PhD under the supervision of K. Jerbi. As to the ODYSSEE project, she is in charge of analyzing MEG data in adults. She is also of valuable help to Hélène Guiraud for MEG analyses in children.

10/02/2014: Rapid speech processing in speech output disorders. Hélène Guiraud will present her data on the perception of rapid speech in children with speech output disorders at LSCD 2014: Workshop on Late Stages in Speech and Communication Development, at UCL (London, 3-4 april) and at 30èmes Journées d'Études sur la Parole (Le Mans, France, 24-27 june). .

31/01/2014: Hannu Laaksonen is leaving. Hannu went back to Helsinki because he got a position at Nokia! We wish him all the best and thank him a lot for his great job on MEG data analysis.

20/11/2012: Post-doc position available (starting date: january 2013). Closed. Applications are invited for a 12-month full-time Postdoctoral Position to perform the MEG experiment and analyze MEG data on speech perception. The ideal candidate will have a PhD in neuroscience, cognitive sciences or a related field and will have substantial experience in MEG imaging analyses (e.g. time-frequency analysis, source estimation techniques and connectivity analysis) and good programming skills (MATLAB). A background in speech and language would be beneficial.
Applications in the form of a cover letter with statement of research interests and a CV with full publication list should be sent by email to veronique.boulenger@ish-lyon.cnrs.fr, with cc to karim.jerbi@inserm.fr.
Applicants from outside the European Union are welcome but they must qualify for a valid visa. French speaking is not a requirement (although it is an asset) as long as the English language is mastered.

24/05/2012: Master's thesis. Hélène Guiraud has defended her Master 1 thesis in Cognitive Psychology and Neuropsychology entitled "Processing of rapid speech: Strategies in production and comprehension" under the supervision of Véronique Boulenger and Nathalie Bedoin. We congratulate her warmly on her excellent work.

30/04/2012: Preliminary results. Hélène Guiraud has carried out a behavioral experiment for her research training. This experiment aimed at examining adaptation to different speech rates in adults and a few children (10-11 years old). Preliminary results do not show the expected effects. However, this pilot study motivates us to pursue our objective with one major observation: we will have to speak faster! A new experiment with a refined protocol should be performed during the summer.

24/02/2012: Kick-off of the project. The project has started in early January, as a new challenge for 2012! We are currently in the process of beginning the behavioral experiments to investigate how typically developing children and adults adapt to time-compressed speech and natural fast speech.
The stimuli have been recorded and we are now processing the acoustic signals. We should be able to start the experiment any time soon.
