An exploration of theta oscillations in the human electroencephalogram: modulation via cognitive activity and real-time feedback

Dr. White's thesis used non-invasive recording techniques to explore an aspect of human brain activity linked with memory, known as the theta rhythm. The role of this activity was characterised during spatial navigation of a virtual environment, demonstrating an association between theta activity and task performance. Subsequently, the feasibility of training increased theta activity by providing real-time feedback was demonstrated and the potential impact of such training was explored. This research provided insights into the functional role of human theta activity, also describing the implementation of novel research methods in the study of brain oscillatory activity.
