The Review Article by Rokem et al. discusses the relationship between mapping white matter (long-distance) cortical connections in the visual system and visual behavior.1) [4 points] The methodology used by Dr. Pestilli involves the use of diffusion imaging andtractography to build maps of human brain anatomy. Briefly describe how this method worksand how it can be used to map anatomical connections in the brain. Describe some of theadvantages and limitations of the approach.2) [4 points] Describe the basic distinction between the dorsal and the ventral visual streams. Whatare some of the main differences between these two streams (neuronal responses, anatomicallocation of brain regions etc)? What do we know about how each of these two streamscontribute to visual function and behavior? Finally, describe what we know about the verticaloccipital fasciculus (VOF) and discuss its potential role in connecting the dorsal and ventralstreams.3) [4 points] If a visual cortical pathway linking different regions of the visual system were to varyin strength among individuals, with some having a stronger connection and others having aweaker connection, what impact might this have on visual behavior? Would you expect to seedifferences in functional connectivity? Feel free to illustrate your discussion with examples fromthe article (e.g. face perception).
