Interested in neuroscience, brain dynamics, and plasticity of complex networks. Especially plasticity of long range connections important for visual processing. Especially in older brains. Professor, UAB Neurobiology sites.uab.edu/kmv/

Histogram showing that representations of peripheral vision for patients with macular degeneration show idiosyncratic connection patterns, but ONLY for the specific area that they use for more attention-demanding tasks (PRL, red).

representation of the visual field, with an image of a duck. The Lesion is a gray blob, and the PRL is a red circle. The PRL is over the duck because the participant is attending to that object.

stronger similarity of connection patterns for peripheral vision than central.

example histogram showing an 'idiosyncratic' pattern -- that isn't particularly similar to typical.

Colors on a brain show the retinotopic mapping of early visual cortex. Colors represent central vision (red) to peripheral vision (blue).
