Researchers have found new clues in the blood that could help explain why Alzheimer’s disease develops and how it affects memory.

Scientists have discovered specialized IC-encoder neurons that make the brain “see” illusions, such as squares or triangles that aren’t truly there. These neurons receive top-down instructions from higher brain areas and then fill in missing contours in the visual cortex, actively constructing what we perceive.

A new PET tracer can provide insights into how spinal cord injuries affect not only the spinal cord, but also the brain, according to new research published in The Journal of Nuclear Medicine. 

Humans excel at adapting to new situations, while machines often stumble. A new interdisciplinary study reveals that the root of the issue lies in how humans and AI approach “generalization,” the process of transferring knowledge to new problems.

An international study has revealed how the brain dynamically adjusts its communication pathways by modulating the balance between two fundamental inhibitory circuits.

A large-scale dietary trial has demonstrated that a green-Mediterranean diet can slow brain aging by modulating key blood proteins associated with neurodegeneration. Using MRI scans and proteomic profiling, researchers tracked nearly 300 participants over an 18-month period and found that diet significantly influenced the brain age gap.

A brain imaging technique has identified areas in the brain’s cerebral cortex that are most susceptible to damage from repetitive impacts, such as those incurred from heading a soccer ball.

Scientists have discovered a mechanism by which nanoplastics disrupt brain energy metabolism, providing new insights into the environmental factors that contribute to neurodegeneration. The particles disrupted mitochondrial electron transfer and reduced energy production in both general and synaptic mitochondria.

Finally, this week, depression’s earliest signs can be hard to spot, but a new study shows AI can detect them in subtle facial movements.
