A new fMRI study suggests that REM sleep helps the brain separate memories after a prediction error, preventing future mistakes. This neural differentiation was observed specifically in the hippocampus of participants who achieved rapid eye movement sleep.
Removing the ATRX protein from murine astrocytes causes deficits in long-term spatial memory while leaving short-term cognition intact. This deletion alters hippocampal gene expression and increases neuronal excitability, proving that glial epigenetic regulation is vital for synaptic maintenance.
Researchers mapped chemical markers on the DNA of zebra finches to understand how the brain changes during critical learning windows. They found that age and sex drive distinct patterns of gene accessibility, linking biological mechanisms to the ability to learn songs.
Researchers have identified a protein, Igfbp2, that transforms brain support cells from caretakers into seizure promoters. This discovery in mice offers a fresh target for treating drug-resistant forms of epilepsy.
Standard dietary advice fails nearly one-third of patients at risk for type 2 diabetes. This review evaluates how biologically specific dietary interventions outperform generic advice for metabolic health.
A systematic review of 54 studies reveals that the adverse risks of Modafinil vary significantly depending on the underlying condition. While insomnia and anxiety are common, physical symptoms like nausea and appetite loss spike disproportionately in specific patient populations.
A systematic review of 27 studies establishes no significant association between bitter taste perception and overall weight status in adults. While general BMI appears unaffected, secondary analysis suggests a potential interaction with body fat distribution.
Researchers have developed a computational tool called GCanner to map distinct regions within parasite DNA. This software differentiates between stable genetic cores and the chaotic, adaptable sections used to interact with hosts.
