Cover Picture: The coordinated action of the eye and the hand is necessary for the successful performance of a large variety of motor tasks based on visual information. In the cerebral cortex of the macaque monkey, the preferred directions (arrows) of parietal neurons studied during different types of eye–hand coordination lie within specific regions of the workspace, known as fields of global tuning (see Battaglia-Mayer et al., Cereb Cortex 11:528–544). These domains are ideal for the dynamic combination of information sharing similar positional and directional tuning properties and might represent a neural substrate for the early composition of combined ocular and manual actions. In the superior parietal lobule, the information encoded in the global tuning fields is embedded in the popu- lation of association cells (transparent view of two-dimensional maps seen in transparency under the hands) projecting to premotor cortex (see Marconi et al., Cereb Cortex 11:513–527). The image of the face is from the David, that of the hands is a detail of the scene of Adam′s Creation (Sistine Chapel, Rome), both from Michelangelo.
