Jaan Tulviste
Jaan’s work at the lab focuses on how the decision-making system is organized in the healthy brain, with a special interest for mechanisms of plasticity which selectively affect specific types of decision-making processes.
Modulating the neural network with TMS allows one to explore cortical mechanisms involved in decision-making and to detect cortical networks responsible for performing specific decision-making tasks. These findings contribute to explaining ‘plasticity’related changes in decisionmaking performance triggered by learning, ageing and disease.
Jaan’s current experiments examine brain networks involved in nonveridical (subjectively correct, personal choicebased ) decision-making, as opposed to veridical decision making (right or wrong answer questions), aiming to validate cognitive tasks that are specifically representative of the nonveridical decision-making system.
The broader goal is to deliver validated tools that make a neurocognitive distinction between different types of decision-making, and to apply these to the development of assessment methods and therapies related to executive functions.
