COMMENT ON “Top-Down Versus Bottom-Up Control of Attention in the Prefrontal and Posterior Parietal Cortices”

Jeffrey D. Schall, Martin Paré, Geoff F. Woodman

Abstract: Buschman and Miller (Reports, 30 March 2007, p. 1860) described the activity of ensembles of neurons in parietal and frontal cortex of monkeys performing visual search for targets that were easy or hard to distinguish from distractors. However, their conclusions are called into question by discrepancies between their results and publications from other laboratories measuring the same neural process.

RESPONSE TO COMMENT ON “Top-Down Versus Bottom-Up Control of Attention in the Prefrontal and Posterior Parietal Cortices”

Earl K. Miller and Timothy J. Buschman

Abstract: We reported latencies for target selection based on the earliest neurons to show effects, which Schall et al. mistakenly compare to latencies based on population averages. We show that there are actually no discrepancies across studies and also discuss the relative merits of single-electrode versus multiple-electrode approaches.
