Alpha oscillations are ubiquitous in the brain, but their role in cortical processing remains a
matter of debate. Recently, evidence has begun to accumulate in support of a role for alpha …

Consciousness is now a well-established field of empirical research. A large body of
experimental results has been accumulated and is steadily growing. In parallel, many …

We often fail to see something that at other times is readily detectable. Because the visual
stimulus itself is unchanged, this variability in conscious awareness is likely related to …

This review examines recent advances in the study of brain correlates of consciousness.
First, we briefly discuss some useful distinctions between consciousness and other brain …

Our visual system can process information at both conscious and unconscious levels.

In 1992, Goodale and Milner proposed a division of labour in the visual pathways of the
primate cerebral cortex between a dorsal stream specialised for the visual control of action …

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention,
working memory, and episodic memory retrieval. Several recent fMRI studies have also …

The brain is assumed to be hypoactive during cardiac arrest. However, the
neurophysiological state of the brain immediately following cardiac arrest has not been …

In masking, a stimulus is rendered invisible through the presentation of a second stimulus
shortly after the first. Over the years, authors have typically explained masking by postulating …
