Summary Statement of Research Interests
Professor Herrera’s research focuses on the development, growth, regulation and plasticity of synapses in the vertebrate nervous system.
Herrera studies the formation and subsequent elimination of the nervous system’s overabundance of synaptic connections during embryonic development. He has shown this occurs through an activity-dependent, competitive process controlled by the expression of ion channels, which results in the permanent adult set of neural connections.
His research on neural development, learning and memory, and neural recovery from injury focuses on long-term effects of altered activity on synaptic efficiency. He uses a frog model to focus on events at the neuro-muscular junction in this research.
In another project, Herrera’s lab investigates the role of Schwann cells in the development and the growth of peripheral synapses. Schwann cells are glial cells that cover and sustain the synapse. He has revealed that Schwann cells lead the growth of motor axons during new synapse formation and synaptic enlargement.
