Imaging Links Fewer Brain Connections to Autism Social Challenges

A recent study used PET imaging to examine synaptic connections in autistic and non-autistic adults, marking the first time this technology was applied to autism research. Findings show autistic adults have fewer synapses, or connections between brain cells, which closely relates to social and communicative differences in autism.

Smiles Are Contagious: Shared Expression Fosters Connection

Smiles during face-to-face conversations strongly impact connection, with the intensity of one person's smile often influencing the other. Researchers found that speakers smiled more when listeners smiled, especially in same-sex interactions, indicating that mutual smiles foster warmth and comfort.

Brain Activity Syncs Differently in Autism and Neurotypical Interactions

A new study shows that brain synchronization between a neurotypical person and someone with autism is weaker compared to two neurotypical individuals interacting. Using EEG hyperscanning, researchers observed reduced inter-brain synchrony during hand movement imitation between mixed pairs, with autistic individuals more likely to follow than lead.

Near Death Experiences May Strengthen Human Interconnectedness

A new study shows that out-of-body experiences (OBEs), including near-death experiences, can dramatically increase empathy and transform how individuals connect with others. Researchers suggest this may result from "ego dissolution," where individuals lose their sense of self and feel deeply connected to the universe.

Mirroring Minds: How Brain Circuits Drive Imitative Behavior

Researchers have discovered how the brain's neural circuits regulate imitative behavior, a key component of social interaction. Using a non-invasive brain stimulation technique, the study shows how specific motor circuits either enhance or inhibit imitation, shedding light on potential clinical applications.

Study Finds Americans Have More Friends Than Previously Thought

American adults typically have more friends than recent surveys suggest, with fewer reporting no friends at all. The survey found that an average American adult has four to five friends, and only 2% reported being friendless. Despite general satisfaction, many adults wish for closer friendships and more time with friends. These findings challenge recent concerns about increasing loneliness and declining friendships.
