As a Ph.D. student, postdoctoral fellow, and in the early years of her laboratory at Wayne State University, Dr. Wolf's work focused on fundamental properties of dopamine neurons and their relationship to antipsychotic drug action. At Wayne State, many of her colleagues studied the neurobiological basis of drug addiction. She therefore learned about prominent theories of addiction, all of which focused on events intrinsic to dopamine neurons. Excited by the groundbreaking work on glutamate receptors and LTP that was coming out at the time, she hypothesized in the late 1980s that the cascade leading to addiction might depend upon glutamate and synaptic plasticity. Her laboratory went on to use behavioral, biochemical, cell biological and electrophysiological approaches to demonstrate that glutamate synapses in the reward circuitry, especially the
nucleus accumbens, undergo complex plasticity after exposure to drugs of abuse and that this plasticity in some cases plays a causal role in behavioral changes that model drug addiction. Her lab continues to characterize synaptic plasticity during abstinence from stimulants and opioids, and to test strategies to harness the understanding of drug-induced synaptic plasticity to develop therapeutic approaches to aid in recovery from substance use disorder. == Awards and honors ==
