The impact of attention on the neuronal mechanisms of adaptation


Brain neurons adapt or change their responsiveness following the repetition of an environmental event, such as the voice or face of an individual. Neuronal adaptation/repetition effects are thought to be important because a reduced response could indicate familiarity with an individual that we have just met and help cognitive processes to recognize and remember the individual. Although the neuronal mechanisms of adaptation are of great interest but remain controversial. This project aims to separate the influences of attention and adaptation effects in the human brain using functional MRI (fMRI), to make direct links with fMRI to work in animal models and to study the “brain” activity response at the neuronal level to gain insights on neuronal mechanisms
