Dorsal and Ventral System

Dorsal and Ventral System

1. Where/How System (M)- Dorsal (towards top)

   • Evolutionarily Older
     • Responsible for motion/space/position
     • Responsible for figure/ground/depth
     • High sensitivity to bright contrast
     • Fast responding and transient
     • Colour Blind
     • Damage effects spatial orientation and location

2. WHat System (P)- Ventral (towards bottom)

   • Object recognition and greater detail
   • Damage affects recognition
   • Coarser Vision
   • Lower and fewer receptive fields
   • Subdivisions are formed and they use colour and luminance to define borders and shapes
   • Lower Resolution
