Presentation description

Male and female Xenopus laevis have distinct calls for reproduction. Testosterone masculinizes female calls, by modifying the vocal pathways. Perineuronal nets (PNNs) are known to regulate neural plasticity. Specifically, PNNs are known to reduce plasticity of fast-spiking parvalbumin (PV) positive neurons. My project aims to test if testosterone modifies calls by reducing PNNs surrounding PV-positive neurons in frogs.
