Tonight’s class: Adult Acquired Cognitive Disorders Topic: Functional dominance and asymmetries in the brain In non-neuroscience terms that means tht the two sides of our brains function differently.  The picture above shows an example of how damage to one side or the other impacts visual perception.  The gist being: the right side of the brain processes stimuli in a holistic way; the left side breaks stimuli into details.  If you damage the right side of your brain, you won’t be able to perceive a whole, but only the details. For example, in the picture above- the patient accurately drew the rectangles, but instead of a gestalt triangle, made three distinct lines.  Vice versa for the left hemisphere. In case you can’t read the caption: “Patients who sustain damage to the right hemisphere can correctly draw the local, or component, parts of the objects, as illustrated by the correct drawing of the Zs and the rectangles.  However, the overall global form is incorrect; it is neither an M (in the case of the linguistic stimulus) nor a triangle (in the case of the nonlinguistic stimulus). In contrast, patients who sustain damage to the left hemisphere can correctly draw the global form of the items but not the local, or component, parts.”

Topic: Functional dominance and asymmetries in the brain

In non-neuroscience terms that means tht the two sides of our brains function differently.  The picture above shows an example of how damage to one side or the other impacts visual perception.  The gist being: the right side of the brain processes stimuli in a holistic way; the left side breaks stimuli into details.  If you damage the right side of your brain, you won’t be able to perceive a whole, but only the details. For example, in the picture above- the patient accurately drew the rectangles, but instead of a gestalt triangle, made three distinct lines.  Vice versa for the left hemisphere.
