Researchers say estimates of how strongly diseases and traits share genetic signals could be over-inflated. Instead, they suggest, mating patterns may help explain the biological relationship between traits.
Brain changes associated with ASD encompass more areas than previously believed, a new study reports. Researchers identified brain-wide changes in all 11 cortical regions analyzed. The greatest gene drop-offs were found in the visual cortex and the parietal cortex, a brain area associated with processing touch, pain, and temperature information. The findings shed light on sensory hypersensitivity associated with ASD. Additionally, researchers say the RNA alterations associated with ASD are more likely a cause than a result of autism.
Higher levels of the inflammatory C-reactive protein were discovered in older breast cancer survivors who experienced cognitive issues. The study is one of the first long-term assessments linking chronic inflammation to cognitive decline in breast cancer survivors.
Study reports warm-blooded animals with higher body temperatures have lower amounts of REM sleep, while those with lower body temperatures have more REM sleep. Researchers say REM sleep acts like a "thermostatically controlled brain heater."
Neurofeedback has the potential to alleviate symptoms of "brain fog" and cognitive impairments associated with chemotherapy.
Researchers have created a new blueprint that outlines how embryonic stem cells from mice become sensory interneurons and identified a method for producing sensory interneurons in a lab setting. If the results can be replicated in human stem cells, researchers say the findings could contribute to the development of therapies to restore sensation to those suffering nerve damage and spinal cord injury.
A study of the cerebral cortex discovered there is a robust response to sound during sleep that largely mirrored the brain's response during wakefulness. However, differences in brain waves that help the brain understand sound and anticipate what comes next is missing during sleep.
Artificial intelligence can understand complex words and concepts by representing the meaning of words in a similar way that correlates with human judgments.
60% of male suicide victims have no prior history of documented mental health problems, a new study reports.
Researchers have identified an area of the brain that appears to play a role in native realism and how we construct our own versions of reality.
