Big EEG(1): Standardized Annotated Neurophysiology Data Repository (Johnson, Kellihan)

Big EEG(2): Large-Scale EEG Analysis and Validation of Hierarchical Event Descriptors (Bigdely-Shamlo, Robbins)

The CaN CTA has invested years of effort in building a standardized data collection containing over twenty studies and millions of annotated events, along with a plethora of tools for curation and processing. This unique resource has the potential to transform interpretation of neural signals by teasing out different aspects of events and states. In this talk we will present preliminary results and insights from two investigations: (a) statistical validation of HED tags, using Representational Similarity Analysis (RSA), by examining similarities in brain dynamics associated with different events (b) characterizing trial variabilities with the application of hierarchical linear modelling to HED-tagged events using LIMO EEG toolbox.

Recent Developments in Noninvasive Human Brain Imaging(Prof. Mingzhou Ding – University of Florida)

In this talk I will describe three ongoing projects that are broadly related to the three programmatic areas of the CaN CTA. The first project examines the technique of recording EEG and fMRI simultaneously. Examples from affective neuroscience and visual attention will be used to illustrate our current approach to integrate complex data from different imaging modalities. The second project examines neural responses to cognitive fatigue resulting from prolonged performance of a cognitively demanding task. We demonstrate that the brain copes with the fatigue-induced impairment of the task-related network by recruiting additional neural resources to maintain performance and that such compensation mechanisms eventually fail as cognitive fatigue further worsens. The third project examines recent efforts at taking neuroscience into the real world. Wireless EEG were recorded simultaneously from all the students in a high school biology class over 11 class periods in the span of one semester. Brain-to-brain synchrony was evaluated and shown to be associated with social and educational assessments.
