brodmann area 6 is premotor cortex in the frontal lobe, this would include the
ventral premotor cortex. Brodmann area 7 is posterior parietal cortex (actually
the superior parietal lobule in humans). Area 7 (as well as the rostral part of
the inferior parietal lobule) is connected to area 6 and the supplimentary
motor cortex. All of which would be working toward visuomotor performance,
spatial recognition, and the analysis of visual motion. 
The ventral stream pathways that I know of, concerned with object recognition,
form and color, involves inferior temporal cortex. This would be composed of
the posterior temporal area and inferior temporal cortex. I don't know there
connections that well, but I understand that they too project to the prefrontal
and premotor areas.
