Special Issue Information
Dear Colleagues,
Understanding consciousness and its evolution in higher-intelligence beings is among the most sought-after subjects desired and explored by intellectuals from every field of studies, including philosophers, physicists, chemists, biologists, neuroscientists, and so on. Since the evolution of modern neurobiological science, consciousness has been classified primarily into two states: wakefulness and sleep. Subsequently, with the progress in knowledge during mid-twentieth century, sleep has been divided into rapid eye movement (REM) sleep and non-REM sleep. The REM sleep is unique in the sense that, although one remains behaviourally asleep, the brain expresses electrophysiological signals comparable to waking. This unique state of REM sleep does not have a voluntary control; most of the dreams appear involuntarily and intermittently during this state. Since the discovery of REM sleep in 1953, in the following seven decades, consistent and significant efforts have been made to understand the biology, neural regulation, and functions of REM sleep. It is known that, at least in the higher vertebrates, REM sleep is an autonomically regulated, instinct behaviour; it is affected in almost all diseases, its loss affects almost all physiological processes, and its sustained loss often become fatal. Notwithstanding, our understanding about REM sleep is far from satisfactory, e.g., we do not know any marker to identify its loss, we cannot control (increase or decrease) it exclusively in a predictive manner; additionally, it is yet unclear if it is a state of consciousness, as well as why and how it modulates consciousness and cognitive ability. Furthermore, during REM sleep, as the brain appears to remain awake during behavioural deep sleep, a detailed understanding of neural and other regulation of REM sleep might facilitate our understanding of consciousness. From time to time, there have been isolated reviews and monographs focusing on various aspects of REM sleep; the most comprehensive one was more than a decade ago. Hence, it is high time that, in response to the significant interest, we produce a dedicated volume dealing with review of advances in the knowledge of REM sleep in the past seven decades, present knowledge as well as challenges and way forward.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs).

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
