Graphic meta-analysis of cortical activations in the course of a delayed matching-to-sample task, paradigmatic of visual delay tasks in a large number of functional neuroimaging studies. A trial begins with the presentation of a face (sample), which the subject must remember for a delay of 10–15 s, at the end of which the subject is presented with two faces and must choose the sample. Little triangles mark the approximate relative timing of the records in the course of a trial. Note the activation of the visual cortex at the sample (excerpt 1), and of the inferior temporal and prefrontal cortices during the delay (excerpts 2–6). From Fuster (2015).
