We have performed the first study utilizing real-time
fMRI neurofeedback (rtfMRI-nf) with simultaneous EEG to
elucidate correlations between BOLD activity of the
thalamus and posterior EEG alpha rhythm. Ten healthy
participants learned to self-regulate fMRI activity of
the anterior and mediodorsal nuclei of the thalamus
using rtfMRI-nf during a task involving retrieval of
happy autobiographical memories. We observed a
significant enhancement in temporal correlation between
thalamic BOLD activity and EEG alpha rhythm during the
rtfMRI-nf training. Our results suggest that rtfMRI-nf
with simultaneous EEG is a powerful tool for studying
relationships between electrophysiology and hemodynamics
of the human brain.
