Astronauts Unconscious Mind Adapting To Microgravity In Space

A study examined that the circadian challenge of astronauts' unconscious mind adapting to microgravity in space, estimated by heart rate variability. It is critical that the regulatory system functions well in space's microgravity. However, the "intrinsic" cardiovascular regulatory system (β), estimated by the fractal scaling of heart rate variability (HRV) (0.0001-0.01 Hz), does not adapt to the space environment during long-duration (6-month) space flights.

Neuroimaging studies suggest that the default mode network (DMN) serves a broad adaptive purpose, its topology changing over time in association with different brain states of adaptive behavior.

Fitness Linked to Depression Patient’s Good Health

Exercise may be just as crucial to a depression patient's good health as finding an effective antidepressant. A new study of nearly 18,000 participants found that those with high fitness at middle age were significantly less likely to die from heart disease in later life, even if they were diagnosed with depression.

Low Developmental Screening and Surveillance Rates in the U.S.

Only about one-third of young children in the U.S. receive recommended screenings or surveillance designed to catch developmental delays. Findings reveal wide variations in rates across states, with as few as 17%t of children under three years old receiving developmental screening in the lowest performing state.

The study was led by researchers at the Johns Hopkins Bloomberg School of Public Health, with colleagues at the federal Maternal and Child Health Bureau and Oregon Health & Sciences University.
