Anotace knihy

Damage to the occipital cortex has traditionally been thoughtto lead to permanent blindness in the contralateral visual field.The existence of residual visual functions in the blind field has,however, been observed and described in cortically blind humans andanimals. This visual phenomenon, whereby patients are able toprocess visual information in their blind visual field without aconscious perception of the stimuli, was first coined blindsight. The neuronal correlate of this phenomenon,however, remains elusive. Advances in neuroimaging techniques suchas Diffusion Tensor Imaging, careful application of paradigms, andstrict control of methodological artifacts have enabled me toconfirm the existence of blindsight in hemispherectomized subjectsand the involvement of the superior colliculi in this phenomenon.My studies demonstrate that superior colliculi connections to theremaining cortical areas play a pivotal role in unconscious vision.In addition, I was able to show that Diffusion Tensor Imaging is apromising, innovative technique to investigate cortical andsubcortical connectivity as well as cortical plasticity.
