Ttadeusz_sfn2015adeusz Kononowicz, PhD • I investigate time estimation processes and self-monitoring of time estimation in the human brain utilizing a combination of EEG, MEG techniques, pattern recognition and cognitive modeling approaches. Unlike earlier studies emphasizing the accumulation processes in time estimation, my current work suggests that the sense of time relies on detection of specific patterns in brain activation and that beta oscillations play a great role in estimating time and in self-monitoring of estimated time.

Sophie Herbst, PhD (in collaboration with University of Lübeck, Germany) • I am interested in how we process and perceive time, and which are the cognitive and neural mechanisms allowing us to do so. We are able to extract temporal regularities from the environment and prepare future actions, for example when we want to cross a street and wait for the traffic light to turn green. We are also able to overtly estimate temporal intervals, but quite often subjective and objective time diverge. In my current project I investigate whether the mechanisms underlying temporal predictions and overt estimates of time do have a common ground using psychophysical methods and neuroimaging (M/EEG).

Laetitia Grabot, MSc • Enjoying music, catching a ball, producing speech… what is the common trait? All these activities need at one point a representation of temporal order, explicitly or implicitly. The interesting situations are when the brain fails to perceive the correct temporal order of external events, thus providing us a window on its mechanisms. I am currently using such paradigms while recording M/EEG data to investigate neural correlates of temporal order perception. I am also studying individual differences in temporal order perception.

Benoît Martin, MSc • Recent hypotheses in cognitive neuroscience suggest the existence of a magnitude system that would encode time, space, number and more generally the “quantity” in a common representational space. My PhD project is devoted to the critical study of the magnitude system in the human brain with an experimental approach combining psychophysics and M/EEG, focusing on the accumulation of sensory evidence in time.

Renan Recio  •  I am Bachelor in Science & Tecnology at Universidade Federal do ABC (2011), Bachelor in Computer Science at Universidade Federal do ABC (2012) and Master in Neuroscience and Cognition at Universidade Federal do ABC (2014). Currently I am a PhD student in Neuroscience and Cognition at the same university. I have an interest in working with Computational Neuroscience (Modeling hippocampal areas), EEG analyzes (EP, phase, power, correlations and causality) , Psychophysical experiments, especially with audio visual perception and recalibration.

Ava Kiai •  I’m a master’s student interning with the Brain Dynamics team. I’m interested in how the predictability and duration of a stimulus affects its perception. I’m also interested in the role of neural oscillations in integrating information from different sensory modalities. I previously received my B.A. from NYU, where I was a research assistant in the labs of Lila Davachi and Marjorie Rhodes. I hope to begin my PhD research in the fall of next year. Find me on Twitter @avakiai or at avakiai AT gmail DOT com

 

jacques-pesnot-lerousseauJacques Pesnot-Lerousseau • Walking in the forest, if you see a bush moving and hear a grunt, you have to quickly infer whether your audio/visual percepts come from the same multisensory object (a bear in the bush) or from different unisensory objects (the wind in the bush and a bear elsewhere). However, given the variate nature of the sensory organs and the specificities of each unisensory processes, this “multisensory correspondence problem” is not trivial to solve. Using MEG, I am trying to understand how the human brain can exploit temporal aspects of the sensory signal to infer the sources of its perceptions.
