Dr. Dani plans his research efforts based on the hypothesis that fundamental mechanisms underlie the communication and adaptability of the nervous system. Those same cellular mechanisms that normally serve the brain are misdirected and damaged during disease and are commandeered and altered by the addiction process. Therefore, fundamental mechanisms underlying neuronal functions offer points of entry for pharmacological, physiological, and genetic methods aimed at relieving or preventing abnormal behaviors of mental disease and drug addiction. From this research prospective, Dr. Dani’s laboratory has made contributions toward our understanding and treatment of neurodegenerative diseases, mood disorders, and addiction. Dr. Dani’s studies will continue to examine the signaling and dysfunction of neurotransmitter systems, which are the chemical signalers of the brain. For example, his studies have shown that addictive drugs induce synaptic changes in the brain that are comparable to those caused during learning, and his lab showed that antidepressant therapies alter the signaling relationships between mood-regulating neurotransmitter systems. Guided by the same fundamental research principles, Dr. Dani’s lab also has contributed to the understanding of memory functions during exposure to drugs and stress or during degenerative disease, such as Parkinson’s disease and Alzheimer’s dementia.
