Induced gamma band responses predict recognition delays during object identification

&amp; Neural mechanisms of object recognition seem to rely on activity of distributed neural assemblies coordinated by synchronous firing in the gamma-band range (&gt;20 Hz). In the present electroencephalogram (EEG) study, we investigated induced gamma band activity during the naming of line draw-ings of upright objects and objects rotated in the image plane. Such plane-rotation paradigms elicit view-dependent process-ing, leading to delays in recognition of disoriented objects. Our behavioral results showed reaction time delays for ro-tated, as opposed to upright, images. These delays were ac-companied by delays in the peak latency of induced gamma band responses (GBRs), in the absence of any effects on other measures of EEG activity. The latency of the induced GBRs has thus, for the first time, been selectively modulated by an experimental manipulation that delayed recognition. This finding indicates that induced GBRs have a genuine role as neural markers of late representational processes during object recognition. In concordance with the view that ob-ject recognition is achieved through dynamic learning pro-cesses, we propose that induced gamma band activity could be one of the possible cortical markers of such dynamic ob-ject coding. &amp
