Neuroimaging studies exploring the neural substrates of executive functioning have only rarely investigated whether the non-executive characteristics of the experimental executive tasks could contribute to the observed brain activations. The aim of t

Previous studies exploring the neural substrates of executive functioning used task‐specific analyses, which might not be the most appropriate approach due to the difficulty of precisely isolating executive functions. Consequently, the aim of this

The neural correlates of two hypothesized emotional processing modes, i.e., schematic and propositional modes, were investigated with positron emission tomography. Nineteen subjects performed an emotional mental imagery task while mentally repeating

Lexicality and phonotactic frequency effects are observed in many cognitive studies on language processing, but little is known about their underlying neural substrates, especially with regard to phonotactic frequency effects. Here, we conducted a po

Humans, like numerous other species, strongly rely on the observation of gestures of other individuals in their everyday life. It is hypothesized that the visual processing of human gestures is sustained by a specific functional architecture, even at

No-carrier-added (nca) l -[11C-methyl]methionine was prepared via the very fast S-alkylation of l -homocysteine adsorbed on Al2O3/KF with [11C]iodomethane at room temperature in ethanol. The alkylation was realized with a radiochemical yield of 94 ±

The radiolabeling of (S)- l -4-chlorophenylalanine and (S)- l -(α-methyl)-4-chlorophenylalanine were realized with carbon-11 at position β through a radiochemical synthesis relying on the highly enantioselective reaction between 4-chloro[α- 11 C]b

This PET study explored the neural substrate of both dual-task management and integration task using single tasks that are known not to evoke any prefrontal activation. The paradigm included two simple (visual and auditory) discrimination tasks, a du

We measured brain activity in 12 adults for the repetition of auditorily presented words and nonwords, before and after repeated exposure to their phonological form. The nonword phoneme combinations were either of high (HF) or low (LF) phonotactic fr
