New research is shedding light on the intricate connections between the brain, body, and behavior. Recent studies have uncovered insights into mental health, aging, movement, trauma, and creativity’s influence on the brain. Here are 11 recent findings that offer a deeper understanding of what shapes us – sometimes down to the molecular level.
Exercise has long been linked to cognitive and emotional benefits, particularly through its impact on the hippocampus. A new study found that tiny particles in the blood called extracellular vesicles may carry proteins and genetic material that can promote neurogenesis, or the growth of new neurons. This discovery supports the idea that exercise has systemic effects and could lead to targeted therapy.
Walking not only moves the body but also changes how the brain processes sound. Researchers recorded brain activity while people walked in a figure-eight pattern, finding that auditory signals became more pronounced during movement. The brain’s sensitivity to peripheral sounds may help people stay aware of their surroundings.
Breast milk contains molecular differences that reflect a mother’s early life experiences. Mothers who reported two or more adverse childhood experiences had higher levels of certain microRNAs and lower levels of specific fatty acids in their milk. These findings suggest that early life trauma may shape biology in subtle ways.
Shyness has traditionally been linked to brain regions involved in emotion, but a new study points to the cerebellum as playing a role. Researchers found that people with higher levels of self-reported shyness had lower levels of synchronized brain activity in the right posterior cerebellum during rest.
A study led by Stanford University scientists identified a precise neural marker that predicts how well children read. Faster neural processing of visual word forms was strongly associated with better reading fluency and comprehension.
Dolphins exposed to algal blooms showed changes in gene expression related to brain inflammation, metabolism, and aging, as well as the presence of amyloid and tau proteins – hallmarks of Alzheimer’s disease.
Mind-body practices like meditation can shift brain function and blood chemistry. Participants who underwent an immersive mind-body retreat showed reduced activity in brain regions tied to self-focus and emotional monitoring, along with increased overall brain network efficiency.
Research found that certain neurons in the brains of people with schizophrenia are physically smaller and more distorted than those in people without the condition.
Sleep is not a uniform process across the brain. Various regions transition into sleep at different rates and with distinct changes in energy use and blood flow.
Finally, research suggests that creative engagement may help the brain stay young. People who regularly engage in creative activities like music or drawing tend to have younger-looking brains.
These 11 breakthroughs offer new insights into the complex relationships between our minds, bodies, and environments. As science continues to uncover the intricate workings of human nature, we can better understand what shapes us – sometimes down to the molecular level.
