A new study comparing stroke survivors with healthy adults reveals that post-stroke language disorders stem not from slower hearing but from weaker integration of speech sounds. While patients detected sounds as quickly as controls, their brains processed speech features with far less strength, especially when words were unclear.

When people facing uncertainty about an important identity goal are nudged to question the validity of their own doubts, their commitment to that goal actually increases. The research demonstrates that inducing meta-cognitive doubt—doubt about one’s doubts—can flip ambivalence into renewed motivation.

A biologically grounded computational model built to mimic real neural circuits, not trained on animal data, learned a visual categorization task just as actual lab animals do, matching their accuracy, variability, and underlying neural rhythms. By integrating fine-scale synaptic rules with large-scale architecture across cortex, striatum, brainstem, and acetylcholine-modulated systems, the model reproduced hallmark patterns

Researchers have engineered a next-generation glutamate sensor, iGluSnFR4, capable of detecting the faintest incoming synaptic signals between neurons—signals that, until now, have been nearly impossible to record in living brain tissue. By capturing these whisper-quiet inputs, scientists can finally observe how neurons weigh thousands of glutamate messages and transform them into an electrical output, the

New research reveals that numbers in our visual field can subtly distort how we judge spatial positions, showing that perception is shaped by both numerical magnitude and object-based processing. In traditional line-bisection tasks, smaller numbers shifted perceived centers leftward, supporting the idea of a mental number line.

A new study challenges the long-held belief that Alzheimer’s disease cannot be reversed. Researchers showed that a severe drop in NAD+—a core energy molecule—drives Alzheimer’s pathology in both human brains and mouse models.

Chronic circadian disruption — such as night-shift work, irregular schedules, or frequent jet lag — accelerates the development and spread of aggressive breast cancer. Researchers found that disrupted internal clocks not only weaken immune defenses but also reshape healthy breast tissue, creating conditions that tumors exploit.
