JHU Researchers Make New Discovery About 3-D Shape Processing in the Brain

While previous studies of the brain suggest that processing of objects and places occur in very different locations, a Johns Hopkins University research team has found they are closely related.

JPEG For the Mind: How the Brain Compresses Visual Information

In the today’s online issue of Current Biology, a Johns Hopkins team led by neuroscientists Ed Connor and Kechen Zhang describes what appears to be the next step in understanding how the brain compresses visual information down to the essentials. They found that cells in area “V4”, a midlevel stage in the primate brain’s object vision pathway, are highly selective for image regions containing acute curvature. Experiments by doctoral student Eric Carlson showed that V4 cells are very responsive to sharply curved or angled edges, and much less responsive to flat edges or shallow curves.
