Synapses are the structures in the brain where neurons connect and communicate with each other. Between early childhood and the beginning of puberty, many of these connections are eliminated through a process called “synaptic pruning.” Stroke, Alzheimer’s disease, and traumatic brain injury can also cause the loss of synapses. But what if new synapses could be created to repair aging or damaged brains?
Stanford neurobiologist Carla Shatz, PhD, addresses this question in the above Seattle+Connect video. In the lecture, she discusses the possibility of engaging the molecular and cellular mechanisms that regulate critical developmental periods to regrow synapses in old brains. Watch the video to learn how advances at the neural level around a novel receptor, called PirB, have implications for improving brain plasticity, learning, memory and neurological disorders.
