Abstract: Understanding the brain computations leading to object recognition requires quantitative characterization of the information represented in inferior temporal (IT) cortex. We used a biologically plausible, classifier-based readout technique to investigate the neural coding of selectivity and invariance at the IT population level. The activity of small neuronal populations (È100 randomly selected cells) over very short time intervals (as small as 12.5 milliseconds) contained unexpectedly accurate and robust information about both object ‘‘identity’’ and ‘‘category.’’ This information generalized over a range of object positions and scales, even for novel objects. Coarse information about position and scale could also be read out from the same population.
