Case study: DB DB’s right primary visual cortex was surgically removed (at the age of  33) for treatment of a non-malignant tumor situated in the right visual  cortex   (V1).   This   intervention   resulted   in   a   dense   hemianopia  (impairment   of   vision)   affecting   the   left   visual   field.     Although   DB  reported no visual awareness in his left field of vision, tests revealed he  was still able to discriminate and identify images on the basis of their  form within his blind field.  During the original testing, he demonstrated  successful   manual   localization,   saccadic   localization,   orientation  discrimination and motion detection. DB was diagnosed as having “blindsight”.  Although he was not consciously aware of  having visual information from his left field, his responses on forced choice guessing  experiments demonstrated that he was somehow receiving visual information.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
