Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Neurofeedback

Background:

Sensorimotor cortex electrical activity influences cognitive processing.
Higher sensorimotor rhythm (SMR) activity is linked to reduced interference and enhanced cognition.
SMR neurofeedback training aims to modulate SMR activity for cognitive benefits.

Purpose of the Study:

To investigate how sensorimotor cortex electrical activity affects cognitive processing.
To determine if SMR neurofeedback training can modulate SMR activity and improve cognitive functions.
To explore the electrophysiological correlates of SMR-induced cognitive improvements.

Main Methods:

Randomized controlled trial with an experimental (SMR neurofeedback) and a control (sham feedback) group.
Participants underwent 10 sessions of neurofeedback training.
Cognitive functions and event-related potentials (ERPs) were assessed pre- and post-training.

Main Results:

The SMR neurofeedback group showed increased SMR power, linked to behavioral improvements in memory and attention.
Increased SMR activity correlated with enhanced stimulus processing, evidenced by larger N1 and P3 ERP amplitudes.
Reduced functional brain connectivity between motor and visual areas indicated decreased sensorimotor interference.

Conclusions:

SMR neurofeedback effectively improves stimulus processing and cognitive performance.
Findings enhance understanding of SMR neurofeedback mechanisms.
SMR neurofeedback shows potential as a cognitive training intervention.
