Localizing cortical computations during visual selection.
Local field potentials (LFPs) and spikes are two signals that can be recorded from the brain using extracellular microelectrodes. A study by Monosov et al. in this issue of Neuron using timing relations between these signals suggests that selection of a target from an array of distractors is a computational operation performed specifically and locally in the frontal eye field (FEF).
