Interactions between phenome and genome at developing CNS synapses during synaptic refinement (2003–2004)
Activity-dependent changes in synaptic transmission are vital to development and function of central neuronal networks. However, the critical factors regulating developmental changes in synaptic signals remain largely unknown. We will correlate functional changes in synaptic responses at glutamate-releasing synapses with changes in glutamate receptor composition at a critical period during development, test whether synaptic activation of receptors is required for these changes and define the pattern of activity-dependent changes in gene expression necessary for developmental changes in synaptic transmission. Understanding this interaction between synaptic phenome and activity-dependent genomic expression will expand our understanding of brain development and function.''
