A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure

The human brain processes spoken language in a step-by-step sequence that closely matches how large language models transform text. Using electrocorticography recordings from people listening to a podcast, researchers found that early brain responses aligned with early AI layers, while deeper layers corresponded to later neural activity in regions such as Broca’s area.​ 

Young children exposed to unusually high temperatures are less likely to reach basic developmental milestones in literacy and numeracy. Analyzing data from over 19,000 children across multiple countries, the study found that average maximum temperatures above 86 °F were associated with measurable declines in early learning outcomes.​ 

New findings show that removing Centaurin-α1, a protein elevated in Alzheimer’s disease, significantly reduces inflammation, plaque buildup, and cognitive deficits in a well-established mouse model. Eliminating this protein normalized several brain pathways, protected neural connections in the hippocampus, and improved spatial learning.​

A new review explores how episodic memories are formed, stored, and reshaped over time, revealing why our recollections of past events often change. Rather than functioning like fixed files, memories consist of multiple components that can lie dormant until triggered by environmental cues.​

New research shows that astrocytes play an active role in nicotine-induced brain changes, challenging the long-held neuron-centered view of addiction. Nicotine stimulates receptors on astrocytes, triggering signaling cascades that boost glutamine synthetase activity and amplify glutamate-related pathways.​

Changes in skin temperature play a key role in how strongly we experience our bodies as our own. Thermoception influences emotion, identity, and mental health by acting as a direct “skin-to-brain” pathway supporting bodily self-awareness.​
