The temporal structure of self-generated cognition is a key attribute to the formation of a
meaningful stream of consciousness. When at rest, our mind wanders from thought to …

PET and fMRI experiments have previously shown that several brain regions in the frontal
and parietal lobe are involved in working memory maintenance. MEG and EEG experiments …

Many powerful human emotional thoughts are generated in the absence of a precipitating
event in the environment. Here, we tested whether we can decode the valence of internally …

Thoughts arise spontaneously in our minds with remarkable frequency, but tracking the
brain systems associated with the early inception of a thought has proved challenging. Here …

Two major non-invasive techniques in cognitive neuroscience, electroencephalography
(EEG) and functional magnetic resonance imaging (fMRI), have complementary advantages …

The human brain evolved to function and survive in a highly stimulating, complex and fast-
changing world. Attempting to ascertain the neural substrates of operating in naturalistic …

Although neural activity often reflects the processing of external inputs, intrinsic fluctuations
in activity have been observed throughout the brain. These may relate to patterns of self …

The primary function of the human brain is arguably to optimize the results of our motor
actions in an ever-changing environment. Our cognitive processes and supporting brain …

Fourteen subjects were scanned in two fMRI sessions separated by several months. During
each session, subjects performed an episodic retrieval task, a semantic retrieval task, and a …

Although mind wandering occupies a large proportion of our waking life, its neural basis and
relation to ongoing behavior remain controversial. We report an fMRI study that used …
