My field of research is neurobehaviour and cognition. I am particularly interested in the cognition that accompanies drug addiction. Brain areas and processes that underlie the drug addiction are overlapping extensively with those that underlie cognition, thus it would be beneficial to know if the treatment of the cognitive impairments is capable of ameliorating continuous drug use. Cognitive flexibilities including learning, memory and attention following drug addiction are evaluated using behavioural paradigms. The underlying neural mechanisms can be further determined by looking at the neurochemical release in specific brain regions using brain microdialysis in freely moving animals.
Current research project:
- Assessment of the cognitive functions following mitragynine substitution in morphine-addicted rats.
- Role of the cholinergic and glutamatergic systems in the cognitive functions following mitragynine substitution in morphine-addicted rats.
