How Multiple Brain Regions Transform Sensory Input Into Action
Researchers used advanced probes to study how mice process sensory input into motor actions. The study found that decision-making involves a distributed network across the brain, with learning enhancing the integration of sensory evidence.

Human-Dog Brain Synchronization and Its Implications for Autism
A study found that human and dog brains synchronize during mutual gazing and petting, with increased synchronization over time. Dogs with autism-like social impairments lost this synchronization, but a single LSD treatment restored it.

Increases in Brain Protein, Not Just Amyloid Clearance, Linked to Slower Cognitive Decline in Alzheimer’s
A study challenges the amyloid plaque theory in Alzheimer’s, showing that increased levels of the brain protein Aβ42 are as strongly correlated with slower cognitive decline as reductions in amyloid plaques.

Throat Issues Linked to Lower Blood Pressure Regulation
A study finds that throat issues lead to reduced baroreflex sensitivity, impairing blood pressure regulation. This reduction may be due to the Vagus nerve prioritizing airway protection over blood pressure control.

Stress Triggers Delayed Increase in Sperm Motility
A study reveals that sperm motility improves after stress rather than during it. By examining extracellular vesicles, researchers found enhanced sperm performance post-stress, suggesting an evolutionary advantage.

AI-Powered Microscopy Technique Can Detect Tumor Cells in Deep Brain Tissue
Researchers at EMBL and Heidelberg University have developed an advanced AI-powered microscopy technique to observe glioblastoma cells in deep brain tissue. This allows real-time tracking of tumor cells in the corpus callosum.

Stigma and Fears Stop People From Discussing Psychedelic Therapy
A study reveals that patients face significant barriers discussing psychedelic substances with their physicians. Stigmatization, perceived lack of knowledge, and fear of damaging the doctor-patient relationship often prevent open conversations.

Variety Makes Us Better Learners
A new study shows that varied practice, not repetition, primed older adults to learn a new working memory task.

How Do Muscles Sense Pressure?
Researchers discovered that muscle spindles detect mechanical pressure, not just muscle stretch. This finding led to the development of the ‘triple-eight’ technique, which effectively reduces muscle stiffness.

Endocrine-Disrupting Chemicals Linked to Early Puberty in Girls
Girls exposed to certain EDCs may be more likely to start puberty early, according to new research. Early puberty is associated with an increased risk of psychosocial problems, obesity, diabetes, cardiovascular disease and breast cancer.
