The origins and development of numerical cognition: This therapy raised her caalculia ability to a high school level after she received treatment for a number of months. Studies of patients with lesions to the parietal lobe have demonstrated that lesions to the angular gyrus tend to lead to greater impairments in memorized mathematical facts, such as multiplication tableswith relatively unimpaired subtraction abilities.
