Understanding the Complexity of Synapses: Seth Grant's Groundbreaking Work
Molecular biologist Seth Grant's research on proteomics of the synapse reveals that synapses contain thousands of proteins, some with short lifetimes and some with long lifetimes. This distribution of proteins across synapses appears to follow a predictable pattern throughout the lifespan, with more long-lived proteins in brain regions associated with higher cognitive functions. Grant's work provides valuable insights into the complexity of synapse function and its implications for neurologic diseases and treatments.
