Abstract
Vision is the dominant sense in humans and the visual system covers about
25% of the human cerebral cortex. The visual cortex contains many maps of
the visual world and many functional regions implicated in processing distinct
perceptual qualities of the visual scene. This chapter provides an overview of
the organization and function of visual cortex, as well as specific data-analysis
techniques that have emerged from functional MRI studies of the visual
system. These data-analysis techniques go beyond the detection of the
presence or absence of an fMRI signal and attempt to reconstruct the
properties of the underlying neural population. Last, the chapter covers some
of the current issues on visual perception, attention and disorders of the visual
system with a particular focus on contributions from fMRI studies.
