The Yale Journal of Biology and Medicine is a PubMed-indexed, open access, quarterly journal edited by Yale medical, graduate, and professional students and peer reviewed by an extensive network of experts in the fields of biology and medicine. The journal aims to showcase outstanding research articles from all areas of biology and medicine, to publish significant case reviews, and to provide both perspectives on personal experiences in medicine and reviews of the current state of biology and medicine.
To all interested authors: Starting in June 2015, YJBM began devoting entire issues to its focus topics. This means that all manuscripts in an issue will be related to the focus topic. As a result, we will not be considering off-topic manuscripts. Please keep an eye out for our future focus topics, and thank you for your understanding.
Each day, we progress through different stages of wakefulness and sleep. As such, our cover depicts the progression of the brain’s electrical activity, shown as EEG waveforms, from an alert state to REM sleep. The sundial at the heart of the image represents the key role that sunlight plays in influencing and entraining our circadian rhythms. This connection between sunlight and physiological clocks and cycles is an integral mechanism that organisms use to best adapt to their environment. Original cover design by Peter Harris.
