This episode of Brain Science features the return of molecular biologist Seth Grant. We briefly review his decades of research into the complexity of the protein structure of the synapse and then we focus on his most recent paper, which describes how the life-span of synapse proteins appears to change as animals age. Grant reflects of the significance of this finding both for animal research and human medicine.

This episode is appropriate for listeners of all backgrounds.

Seth Grant has previously appeared on Brain Science several times including BSP 51, BSP 101, BS 137, BSP 150 and BS 176.
