Agnirva Space Premier League - Expedition #30467: Synapses in Space: Exploring Brain Development in Microgravity

How does space affect the formation of synapses—the connections between nerve cells that allow us to think, feel, and move? This question led Dr. Haig Keshishian and his team at Yale University to study synaptogenesis in microgravity. Using the Commercial Generic Bioprocessing Apparatus (CGBA), researchers sent neural tissue cultures to the ISS to observe how nerve cells grow and connect in the absence of gravity. This is especially important for understanding neurodevelopment and cognitive function during long-duration missions. Initial results indicate that microgravity may influence the size, density, and formation rate of synaptic connections. These insights could help scientists protect astronaut brain health and may even have implications for treating neurodegenerative conditions like Alzheimer’s on Earth. As we explore the frontier of brain science in orbit, these studies push the boundaries of both space medicine and neuroscience.
