Summary Source
The ADHD-200 Sample is a grassroots initiative, dedicated to accelerating the scientific community’s understanding of the neural basis of ADHD through the implementation of open data-sharing and discovery-based science. Towards this goal, we are pleased to announce the unrestricted public release of 776 resting-state fMRI and anatomical datasets aggregated across 8 independent imaging sites, 491 of which were obtained from typically developing individuals and 285 in children and adolescents with ADHD (ages: 7-21 years old).
This is the second part of the expriment on Pattern Separation. This processes the participants hits and misses into the induced negative or neutral group and displays some results.

The following was the code used to prepare images from the IAPS database for a experiment on pattern separation. The participants were seated in front of a PC and went through three tasks: Encoding, retreival and validation.
