Healthy adults transition from surveillance to automated processing within minutes of mental exertion despite stable behavioral performance.
Simultaneous Cochlear Implants Improve Long-Term Sound Localization
Adolescents with simultaneous bilateral implants show superior spatial hearing compared to those with a brief sequential delay.
Advanced MRI Detects Occult Neuronal Loss in Asymptomatic MCA Occlusion
Soma and neurite density imaging reveals microstructural gray matter damage in stroke-free patients with chronic arterial occlusion.
Obesity and Prediabetes Rates Rise Among Northern Great Plains Children
A multi-year screening of American Indian students shows obesity rates exceeding 40% and a doubling of prediabetes prevalence.
Daily Task Frequency Correlates With Objective Activity in Cardiac Patients
A study of 1,126 patients shows that housework and leisure activities drive higher step counts and moderate-to-vigorous exertion.
Mental Health Gains Tied to Cessation, Not E-Cigarette Switching
A large study links complete cessation to better mental health over time, a benefit not seen in those who switch to e-cigarettes.

Metabolic imaging reveals that glutamate ratios in the nucleus accumbens and cingulate cortex correlate with neural instability markers.
Seven Hours of Sleep Maximizes Depression Risk Reduction in Older Adults
A national cross-sectional study reveals a non-linear relationship where the mental health benefits of sleep attenuate after seven hours.
ADHD Linked to Attenuated Rightward Structural Asymmetry in Children
MRI data reveal that reduced right-hemisphere dominance in frontal and striatal regions correlates with impaired attention and timing.
