• Carbon Wire Loops (CWLs) in EEG-fMRI studies of interictal epileptic activity

Carbon Wire Loops in EEG-fMRI studies of interictal epileptic activity

At the Montreal Neurological Institute and Hospital, we work with combined EEG and fMRI acquisition to study epileptic patients to determine the brain region responsible for the generation of seizures that characterize this condition. We use Carbon Wire Loops to help recover a clean signal from the EEG recorded in the MR environment.

  • First Steps to Using Carbon Wire Loops (CWLs) to Correct for Artifacts in simultaneous EEG-fMRI

First Steps to Using Carbon Wire Loops to Correct for Artifacts in simultaneous EEG-fMRI

EEG signals acquired in parallel to fMRI data require the handling of artifacts in the EEG dataset due to electrode motion, for example, by blood pulsation. Using carbon wire loops placed on EEG caps allows you to directly measure these artifacts and subsequently correct for them efficiently using a regression-based approach.

  • Methodology for characterizing network activations with neuro-navigated TMS and EEG

Methodology for characterizing network activations with neuro-navigated TMS and EEG

This aEEG-TMSrticle walks you through the collection of neuro-navigated simultaneously obtained Transcranial Magnetic Stimulation (TMS) evoked EEG (TMS-EEG) data to investigate network-specific TMS-induced EEG activations, as in Ozdemir et al, 2020 (PNAS), focusing specifically on the methods of TMS-EEG data collection and analysis.

  • From Movement to Action: An EEG Study into the Emerging Sense of Agency in Early Infancy

From Movement to Action: An EEG Study into the Emerging Sense of Agency in Early Infancy

This study investigates whether 4-month-old infants build causal action-effect models, a prerequisite for a sense of agency. Using behavioral and neural measures of violation of expectation, we found evidence for causal models only in a subset of infants. Thus, the sense of agency is beginning to emerge at this age.

  • Simultaneous EEG-fMRI reveals neural substrates during sleep that support Fluid Intelligence

Simultaneous EEG-fMRI reveals neural substrates during sleep that support Fluid Intelligence

This user research article summarizes the publication “Brain Activation Time-Locked to Sleep Spindles Associated With Human Cognitive Abilities”. Here, simultaneous EEG-fMRI recordings were used to understand the functional significance of interindividual differences in brain activations, time-locked to sleep spindles.

  • Alcohol Hangover Impacts Learning and Reward Processing Within the Medial-Frontal Cortex

Alcohol Hangover Impacts Learning and Reward Processing Within the Medial-Frontal Cortex

Alcohol intoxication impairs motor coordination, judgement, and decision-making. Interestingly, research suggests that the impact of alcohol consumption continues beyond the point of intoxication and into a period of alcohol hangover. Here, we examined differences in the amplitude of reward positivity – an event-related brain potential component associated with learning and how the amplitude of this component was impacted by alcohol hangover
