Cells in the retina or in the early visual cortex respond to small parts of images. One of our research lines focuses on understanding how our brain integrates segmented visual information into a global percept.
I adopted a collinear facilitation paradigm, in which the detection ability of a Gabor stimulus that resembles the receptive field of V1 cells, was compared in the absence and presence of various surround Gabor stimuli (see figure below).
My studies showed that detection ability is influenced by chromaticity, stereopsis, texture and temporal properties between the target and the surround stimuli, contributing important findings to the field of spatial vision in behavioral studies and providing crucial evidence for independent cortical processing in long-range interactions in the early visual cortex and supporting physiological studies as well.
Figure. Demonstration of collinear facilitation paradigm. The experiment is to compare the detection threshold of the central target in the present or absence of the flankers. Usually, the properties of the flankers was varied in order to investigate how the properties of the flankers influence the detection threshold of the target.
