Efects of Acute Aerobic Exercise on Response Inhibition in Adult Patients with ADHD

Experimental task. Te experimental paradigm was programmed using Cogent 2000 v125 (http://www.vislab.ucl.ac.uk/cogent.php) and Matlab R2015b (Te MathWorks, Inc.) and was projected onto a screen andpresented to the participants in the scanner through a mirror on the head coil. Te distance from the eyes of theparticipants to the screen was 50cm. Stimuli were white and displayed…

Neural substrates underlying motor skill learning in chronic hemiparetic stroke patients

Prior to the fMRI activation runs, a resting-state run was acquired except in patients #1–4 and #17. The resting-state acquisition consisted of one single 6-min run during which the patients kept their eyes closed and had to avoid moving or falling asleep. Then, the patients performed two consecutive activation runs of motor skill learning with…

Automatic and fast encoding of representational uncertainty underlies probability distortion

Subjects were seated approximately 86 cm in front of a projection screen (Panasonic PT-DS12KE: 49.6 × 37.2 cm, 1024 × 768 pixels, 60-Hz refresh rate) inside the magnetically shielded room. Stimuli were controlled by a Dell computer using Matlab and PsychToolbox-3 (Brainard, 1997; Pelli, 1997). Subjects’ behavioral responses were recorded by an MEG-compatible mouse system (FOM-2B-10B…

Combined expectancies: the role of expectations for the coding of salient bottom-up signals

Stimuli were presented on a 22-in. Samsung SyncMaster monitor (spatial resolution 1680 X 1050; refresh rate 120 Hz) at a distance of 60 cm. A chin and forehead rest preserved the distance. The presentation of stimuli and response recording were controlled using PsychoPy psychology software for Python (Peirce 2007, 2008). Participants were provided with button response pads (NAtA Technologies)…
