Awakening: Predicting external stimulation to force transitions between different brain states

Gustavo Deco, Josephine Cruzat, Joana Cabral, Enzo Tagliazucchi, Helmut Laufs, Nikos K. Logothetis, Morten L. Kringelbach
2019 Proceedings of the National Academy of Sciences of the United States of America  
Specifically, we use a unique neuroimaging dataset of human sleep to systematically investigate where to stimulate the brain to force an awakening of the human sleeping brain and vice versa.  ...  Given the biophysical limitations of direct electrical stimulation (DES) of microcircuits, this opens exciting possibilities for discovering stimulation targets and selecting connectivity patterns that  ...  This allows for recurrent substates to be detected and characterized in terms of probability of occurrence and alternation profiles.  ...

A refined model of sleep and the time course of memory formation

Matthew P Walker
2005 Behavioral and Brain Sciences  
Research in the neurosciences continues to provide evidence that sleep plays a role in the processes of learning and memory.  ...  In contrast, the consolidation stage, resulting in additional/enhanced learning in the absence of further rehearsal, does appear to rely on the process of sleep, with evidence for specific sleep-stage  ...  This work was supported by the National Science Foundation (BCS-0121953) and the National Institute of Health (MH-48832 and DA11744-01A1).  ...
