Brain scans during sleep can decode visual content of dream. Researchers led by Yukiyasu Kamitani of the ATR Computational Neuroscience Laboratories
in Kyoto, Japan used functional neuroimaging to scan the brains of
three people as they slept, simultaneously recording their brain waves
using electroencephalography (EEG). The researchers woke the participants whenever they detected the pattern
of brain waves associated with sleep onset, asked them what they had
just dreamed about, and then asked them to go back to sleep. The researchers extracted key words from the participants’ verbal
reports, and picked 20 categories that appeared most frequently in their
dream reports.

Brainwave training boosts brain network for cognitive control
Researchers at University of Western Ontario and the Lawson Health Research Institute have found that
functional changes within a key brain network occur directly after a
30-minute session of noninvasive, neurofeedback training.[ more ]
