Human cortical excitability increases with time awake
Prolonged wakefulness is associated not only with obvious changes in the way we feel and
perform but also with well-known clinical effects, such as increased susceptibility to seizures …

Quantifying cortical EEG responses to TMS in (un) consciousness
We normally assess another individual's level of consciousness based on her or his ability to
interact with the surrounding environment and communicate. Usually, if we observe …
