How is conscious experience related to material brain processes? A variety of theories
aiming to answer this age-old question have emerged from the recent surge in …

Sleep is a universal, essential biological process. It is also an invaluable window on
consciousness. It tells us that consciousness can be lost but also that it can be regained, in …

Consciousness can be conceptualized as varying along at least two dimensions: the global
state of consciousness and the content of conscious experience. Here, we highlight the …

By connecting old and recent notions, different spatial scales, and research domains, we
introduce a novel framework on the consequences of brain injury focusing on a key role of …

Perturbational complexity analysis predicts the presence of consciousness in volunteers and
patients by stimulating the brain with brief pulses, recording EEG responses, and computing …

The cerebral cortex is widely considered part of the neural substrate of consciousness, but
direct causal evidence is missing. Here, we tested in mice whether optogenetic activation of …

The nucleus accumbens (NAc) is a brain hub regulating motivated behaviors, including
social competitiveness. Mitochondrial function in the NAc links anxiety with social …

Neuronal interactions give rise to complex dynamics in cortical networks, often described in
terms of the diversity of activity patterns observed in a neural signal. Interestingly, the …

It has been suggested that consciousness is closely related to the complexity of the brain.
The perturbational complexity index (PCI) has been used in humans and rodents to …

To investigate mechanisms underlying loss of consciousness, it is important to extend
methods established in humans to rodents as well. Perturbational complexity index (PCI) is …
