Recent years have seen a blossoming of theories about the biological and physical basis of
consciousness. Good theories guide empirical research, allowing us to interpret data …

We review the central tenets and neuroanatomical basis of the global neuronal workspace
(GNW) hypothesis, which attempts to account for the main scientific observations regarding …

Humans are voracious imaginers, with internal simulations supporting memory, planning
and decision-making. Because the neural mechanisms supporting imagery overlap with …

A thought-provoking argument that consciousness—more widespread than previously
assumed—is the feeling of being alive, not a type of computation or a clever hack In The …

The role of the frontal cortex in consciousness remains a matter of debate. In this
Perspective, we will critically review the clinical and neuroimaging evidence for the …

Why are some visual stimuli consciously detected, whereas others remain subliminal? We
investigated the fate of weak visual stimuli in the visual and frontal cortex of awake monkeys …

Deep non-rapid eye movement sleep (NREM) and general anesthesia with propofol are
prominent states of reduced arousal linked to the occurrence of synchronized oscillations in …

The brain is assumed to be hypoactive during cardiac arrest. However, animal models of
cardiac and respiratory arrest demonstrate a surge of gamma oscillations and functional …

Dreams take us to a different reality, a hallucinatory world that feels as real as any waking
experience. These often-bizarre episodes are emblematic of human sleep but have yet to be …

Despite the absence of responsiveness during anesthesia, conscious experience may
persist. However, reliable, easily acquirable and interpretable neurophysiological markers of …
