Why does artificial touch fade over time? Penn State engineers used fNIRS brain imaging to solve sensory habituation during transcutaneous nerve stimulation, discovering a 5-second pulse protocol that maintains a stable sense of touch while the brain recruits distributed networks.

Michael W. Cole’s new book makes a convincing case that the dynamic movement of signals underpins just about everything the brain does, though it misses mention of relevant theoretical and single-cell work.

A surprising discovery suggests that some early signs of Alzheimer’s disease may begin outside the brain. Using miniature laboratory systems made from human cells, scientists found that genetic mutations associated with inherited Alzheimer’s can disrupt nerve-to-muscle connections without any involvement from the brain or spinal cord. This could help explain why some patients experience changes in balance, walking…

Scientists propose that the brain’s mysterious cross-wiring, which connects each hemisphere to the opposite side of the body, may have originated more than 500 million years ago in the visual systems of ancient fish. Rather than evolving for a specific advantage, this unusual arrangement may simply be a legacy of evolution building new brain circuits on an ancient foundation.

A surprising discovery at UC San Diego suggests that chronic lower back pain may become deeply embedded in the brain's sense of personal identity. Researchers found that movement-triggered pain activates a brain network associated with self-awareness and memories, even though ordinary acute pain typically shuts this network down. This unexpected difference could explain why conventional pain medications often…
