Abstract

We process and encode for different features of a particular object (shape, color, texture, etc.) in distinct areas of the brain. How we bind these attributes together into a unified perception of an object is unknown. Past research suggests that synchronized activity between brain areas, particularly induced gamma activity (~ 40 Hz), may account for this binding process and the basis of our conscious perceptual experience, specifically through object representation. In this study, participants were asked to look at a series of 2-D pictures of cars from distinctive rotations (0⁰, 90⁰, 180⁰) and were asked to distinguish whether two pictures are of the same or different cars; meanwhile, electroencephalography (EEG) was used to measure electrical activity on participants’ scalps. Our preliminary analysis showed a difference in gamma oscillation after the stimulus onset when comparing 180⁰ rotations to no rotation in one participant. This suggests the possible relationship between induced gamma oscillation and 3-D object representation.
