Overview
This study details a molecular readout of long-term olfactory adaptation in Caenorhabditis elegans, focusing on the role of Protein Kinase G, EGL-4. The research demonstrates how EGL-4 translocates from the cytosol to the nucleus in response to prolonged odor exposure, indicating stable adaptation in sensory neurons.
