Study Confirms Early Brain Differences Between Sexes

A study analyzing over 500 newborns has confirmed that brain structure differences between male and female infants are present from birth. While male brains were larger on average, females had more grey matter in regions related to memory and emotion, whereas males had more white matter and grey matter in sensory and motor regions.

Females Sleep Less and Wake More: A New Study Reveals Why

Females experience less total sleep, more frequent awakenings, and reduced restorative sleep compared to males, according to a new study on mice. Researchers attribute these differences to biological factors rather than lifestyle, potentially linked to stress hormones and evolutionary roles.

Sex-Based Breakfast Choices May Boost Metabolism

A recent study using mathematical models suggests that breakfast choices may affect men’s and women’s metabolisms differently. Results indicate that men’s metabolisms respond better to carb-heavy breakfasts, while women’s bodies benefit more from higher-fat options like eggs or avocados, especially after fasting.

Men Show Higher Genetic Risk for Schizophrenia and Related Disorders

Researchers have found that schizophrenia shares genetic risk factors with bipolar disorder and major depression, with these vulnerabilities being more significant in men than in women. This new study analyzed over 3,000 individuals, finding that polygenic scores for various psychiatric disorders contribute differently to psychosis risk based on gender.

Sex Differences Found in Brain’s Reward Pathways

A new study reveals sex differences in how the brain's reward pathways function, specifically in the hippocampus and nucleus accumbens. Males and females use different molecular mechanisms to strengthen these connections, influencing responses to treatments for disorders like depression and substance abuse. The findings highlight the need for more gender-specific research to develop effective therapies. Researchers hope this will lead to improved patient outcomes.

Astrocyte Receptors Impact Memory Differently in Men and Women

Researchers discovered that astrocyte receptors impact cognitive function differently in male and female preclinical models. The study reveals that astrocytic signaling cannot be assumed to have the same cognitive effects across sexes. This finding suggests that therapies targeting astrocytic receptors may need to consider sex-specific impacts.
