This increased connectivity was stronger between the cerebellum and left frontal cortex, indicating a more efficient brain organization in terms of functional connectivity.
New research suggests parenting programs that address both mental health and parenting skills can improve children's development. However, these programs often fall short in providing effective mental-health support for parents, who may struggle with depression during the perinatal period.
A new University of Colorado Boulder study sheds light on why paternal mitochondrial DNA is eliminated during development. The research found that delaying this process can lead to lasting neurological and behavioral problems in adults. Treatments such as Vitamin K2 may offer new hope for preventing or treating these disorders.

Aging brains struggle to clear out outdated information, leading to slower processing and more frequent forgetfulness. Beta-band neural oscillations play a crucial role in regulating working memory, with older adults showing a stronger link between these oscillations and their ability to delete irrelevant information.
A new study finds that excessive social media use is associated with a higher risk of eating disorder symptoms in 9-14-year-olds, including binge eating and distress over weight gain. Problematic screen use may contribute to unhealthy behaviors and addictive tendencies.
A comprehensive review of genetic and population studies challenges conventional wisdom about the relationship between genetic risk and cognitive deficits in schizophrenia. Premorbid cognitive impairment is largely explained by non-familial factors rather than inherited genetic variants.
Researchers aim to develop a voice assistant delivering customized cognitive stimulation therapy to improve the quality of life for persons living with dementia and their care partners. The project has the potential to positively impact a large population, including those in remote areas.
Children's brains cannot focus on tasks because their working memory is not fully developed, according to a new study. Researchers found that even with rewards, children still 'over explore' and gather unnecessary information. This suggests that kids are naturally curious and unsure of retaining information in their memory.
