New video publication on infant EEG. “Novel Experimental and Analytical Approach to the Multimodal Neural Decoding of Intent During Social Interaction in Freely-behaving Human Infants”

by Stefanie Rudrich Marketing Manager (Brain Products)… A research group from University of Houston presented a novel methodology for the neural decoding of intent from freely-behaving infants during unscripted social interaction with an actor. Neural activity was acquired using actiCAP EEG electrodes. Kinematic data was collected with inertial measurement units and supplemented with synchronized video…

Simultaneous EEG–fMRI at ultra-high field: Artifact prevention and safety assessment

by João Jorge1,2 1Laboratory for Functional and Metabolic Imaging, EPFL, Lausanne, Switzerland 2Institute for Systems and Robotics, IST, Lisbon, Portugal Introduction Simultaneous EEG-fMRI acquisitions can offer valuable insights for the non-invasive study of human brain function (Britz et al., 2010; Gotman and Pittau, 2011; Scheeringa et al., 2011). Concurrently, the benefits offered by high-field imaging,…

Integration of concurrent real-time fMRI and EEG data: Self-regulation of human brain activity using simultaneous real-time fMRI and EEG neurofeedback

by Jerzy Bodurka1,2 1Laureate Institute for Brain Research, Tulsa, OK, USA 2College of Engineering, The University of Oklahoma, Tulsa, OK, USA Synopsis We integrated concurrent real-time fMRI (rtfMRI) and electroencephalography (EEG) data on commercial MRI and EEG equipment. We also report a proof-of-concept experiment using simultaneous multimodal rtfMRI and EEG neurofeedback (rtfMRI-EEG-nf). With this approach…
