Cover legend: Information from different reward and cognitive-related cortical areas terminate in both separate and converging striatal regions. The schematic drawings illustrate the cortical terminal fields at different rostrocaudal levels. Each color represents different cortical areas (pink, ventral, medial prefrontal cortex; dark orange, orbital prefrontal cortex; light orange, dorsal anterior cingulate cortex; yellow, dorsolateral prefrontal cortex). There are two labeling patterns, a focal projection field consisting of dense terminal fields (illustrated in the top right hand corner) and a diffuse projection consisting of clusters of fibers, extending throughout a wide striatal region. The bottom panel shows diffuse terminals superimposed onto the dense projection illustrating the interface of the diffuse and focal projections. For more information see the article by Haber et al., in the August 9, 2006 issue (Vol 26, Issue 32, 8368–8376).
