Genomic organization and transcripts of the zebrafish Protocadherin genes.

We have examined the protocadherin (Pcdh) gene clusters of the zebrafish (Danio rerio). At least three sets of the Pcdh gene cluster were found in the zebrafish genome. Here, we describe the complete organization of the DrPcdh2 gene clusters.

Visual responses in the temporal cortex to moving objects with invariant contours.

We were interested in how the visual attributes of motion and shape are integrated in the temporal cortex of monkeys. We recorded neural activity in the middle portion of the superior temporal sulcus (STS) of monkeys during a sequential visual discrimination task while the animals maintained fixation. We used images of objects with invariant outlines rotating in 3D space either clockwise or counterclockwise as visual stimuli.
