While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new study has nonetheless uncovered a key mechanism by which sleep enhances neuronal and behavioral performance, potentially changing our fundamental understanding of how sleep boosts brainpower.

Working with week-old zebrafish larva, researchers decoded how the connections formed by a network of neurons in the brainstem guide the fishes' gaze. The study found that a simplified artificial circuit, based on the architecture of this neuronal system, can predict activity in the network. In addition to shedding light on how the brain handles short-term memory, the findings could lead to novel approaches for treating eye movement disorders.

A new study found that prolonged standing at work had a negative impact on the research participants' 24-hour blood pressure. In contrast, spending more time sitting at work was associated with better blood pressure. The study suggests that activity behavior during working hours may be more relevant to 24-hour blood pressure than recreational physical activity.
