This Week in Neuroscience

TWiN reviews how, in a mouse stroke model, recovery of movement is associated with the remaining cortex and the striatum coordinating their activity together.

TWiN explains the observation that in mice, the HIV-1 co-receptor CCR5 closes the temporal window for linking different memories.

The hosts kick off with funny weather stories before diving into the serious realm of Parkinson's disease. They discuss groundbreaking research showing how gut-injected alpha-synuclein can spread to the brain, triggering the disease. The multifaceted nature of Parkinson's, including motor and cognitive impacts, takes center stage. Exciting insights reveal the gut as a potential origin for disease pathology. The conversation also unpacks the role of misfolded proteins in neurodegeneration, emphasizing the connection between gut health and cognitive decline.

TWiN explains the finding that in the mouse visual cortex, astrocytes are key elements in the experience-dependent wiring of brain circuits.

Bruce Carter joins TWiN to discuss the peripheral nervous system: the development of nerves that convey sensory information like touch from the tips of your toes to the brain, and Schwann cells, which are necessary for ensuring that those sensory signals are sustained as they travel long distances to the brain.
