In classical fear conditioning, a neutral stimulus (for example, a red car) becomes associated with a fearful event (for example, being in a car crash). Because of this association, the original fear response becomes associated with the neutral stimulus. A reduction of this fear response can be achieved by extinction learning: repeated exposure to the neutral stimulus in the absence of the fearful event. A new memory trace is created where ...
This project studies the impact of imagination on two related yet separable forces that guide human reward-seeking behavior: wanting and liking [1]. Wanting is felt as a desire prior to consumption which ultimately leads to a motivational state to interact with a product or service (i.e., purchase, consume). Liking involves a post-consumption evaluation of the experienced pleasure and facilitates an emotional state [1, 7]. Over the past ...

Brain-Computer Interfaces (BCIs) decode brain activity with the aim to establish a communication channel that does not rely on muscular control. BCIs usually rely on EEG signals acquired from the subject's scalp or on electrophysiological signals from brain implants. The latter yield a superior decoding performance, but as the implant damages the cortical tissue, long-term signal stability is a concern. EEG does not require surgery but the ...
