A recent study published in the Journal of Social and Personal Relationships explores how adolescent attachment styles influence brain activity in adulthood during social interactions. The findings reveal that securely attached adolescents exhibit increased brain activity in regions associated with emotion, cognition, and reward when holding hands with a romantic partner or even a stranger. These results suggest that the quality of attachment in adolescence can shape adult responses to social support at a neural level. Attachment theory posits that early relationships with caregivers form the ...

A recent scientific study published in the journal Brain Structure and Function provides evidence that social isolation not only impairs the ability of mice to recognize other mice socially but also leads to a decrease in brain cells. The research highlights the importance of social interaction in early life on brain health and social cognition. Previous studies have established a link between social deprivation and various brain changes in humans and animal models, particularly affecting areas involved in emotional processing and social interaction. However, gaps remain in understanding the s...

In a study published in Brain Communications, researchers have found evidence that individuals with aphantasia, a condition where people struggle to create mental images, exhibit significant differences in brain activity related to motor simulations compared to those without this condition. The study found that people with aphantasia do not show the expected increase in brain activity that typically occurs when imagining or observing movements, which contrasts sharply with individuals who can easily generate mental images. Aphantasia is a condition where individuals are unable to generate volu...

Researchers at the Paris Brain Institute have conducted a groundbreaking study on the processes that occur in the brain as it transitions from life to death, particularly focusing on a phenomenon called the “wave of death.” The study, published in the journal Neurobiology of Disease, reveals that the final cessation of brain activity involves a dramatic wave of neuronal depolarization, which could potentially inform interventions in cases of acute brain injury and cardiorespiratory arrest. Understanding the brain’s response to severe oxygen deprivation has long been a subject of intense resear...

A longitudinal study of older adults has shown that individuals with higher concentrations of amyloid beta proteins in their brains experienced accelerated cognitive decline. This finding suggests that a single positron emission tomography (PET) scan assessing amyloid beta protein levels in the brain could be sufficient to predict the rate of cognitive decline in individuals. The study was published in the journal NeuroImage: Clinical. Amyloid beta (Aβ) plaques are protein deposits that accumulate in the brains of individuals with Alzheimer’s disease and, to a lesser extent, in several other t...

Recent scientific advancements have shed light on the potential synergistic effects of meditation and psychedelic substances. A study published in Scientific Reports reveals how psilocybin, a psychedelic compound, when combined with open monitoring meditation may enhance the depth of insightfulness in experienced meditators. This enhancement appears to be mediated by changes in the brain’s organizational patterns. Open monitoring meditation is a type of meditation that emphasizes the broad, non-reactive awareness of the content of experience from moment to moment. Unlike focused attention medi...

In a study recently published in the Journal of Affective Disorders, researchers have found evidence suggesting that certain types of gut bacteria may influence the thickness of the brain’s cortex. The study identifies specific bacteria within the orders Lactobacillales and Bacillales that are potentially associated with changes in brain structure. Our gut is teeming with microorganisms that influence various aspects of our health, from metabolism and immunity to our risk for diseases. Recently, scientists have begun to explore how these microbes might also impact the brain. This interaction b...

Researchers from the University of Bern have found a significant connection between the quality of our deep sleep and how likely we are to engage in prosocial behaviors, such as cooperating with others and making charitable donations. The study shows that brain activity during deep sleep, particularly in the right temporoparietal junction, can predict prosocial tendencies in everyday life. The results have been published in The Journal of Neuroscience. Human societies thrive on cooperation and altruism, with individuals regularly participating in actions that benefit others, such as volunteeri...

Scientists in Germany have found evidence that a single large dose of creatine, a supplement commonly embraced by athletes for physical performance enhancement, can temporarily uplift cognitive abilities diminished by lack of sleep. Published in Scientific Reports, the findings open a new chapter in understanding how dietary supplements can influence brain function under stress conditions such as sleep deprivation. Modern lifestyles often compromise sleep, leading to decreased productivity and an increase in accidents and chronic health issues. To combat these negative effects, people frequent...

New research reveals that even infants as young as four months old have an innate ability to comprehend how their bodies interact with the world around them. This understanding is evident as they process different sensory information based on the movement of objects they see coming towards them. The study, published in Scientific Reports, highlights early development stages of self-awareness. For decades, scientists have been fascinated by how humans perceive and interact with the space immediately around them—what is known to researchers as “peripersonal space.” This concept explores how we i...
