Drug-Coated Neural Implants Reduce Immune Rejection

A new study shows that coating neural prosthetic implants with the anti-inflammatory drug dexamethasone helps reduce the body’s immune response and scar tissue formation. This strategy enhances the long-term performance and stability of electrodes used to connect prosthetic limbs to the nervous system.

Pregnancy Reshapes Mom’s Brain, Reducing Gray Matter

Pregnancy leads to a 4.9% reduction in gray matter volume in 94% of the brain, with partial recovery postpartum, primarily in regions tied to social cognition. A groundbreaking neuroimaging study analyzed brain changes in 179 women, including non-gestational mothers, revealing that these changes are biologically driven by pregnancy hormones rather than the experience of motherhood.

How the Brain Extinguishes Fear Memories

Scientists have, for the first time, identified the brain signals linked to extinguishing fear memories in humans. Using implanted electrodes and advanced Representational Similarity Analysis, they showed that theta activity in the amygdala increases when previously unpleasant cues are re-learned as safe.
