title: Binocular matching in monkey visual cortex: single cell responses to correlated and uncorrelated dynamic random dot stereograms.
abstract: This paper presents results obtained from experiments performed on two behaving monkeys (Macaca mulatta) viewing correlated and uncorrelated dynamic random dot stereograms. Extracellular single unit activity was recorded from areas V1 and V2. We found that cells sensitive to correlated stereograms (38%) were also sensitive to uncorrelated stereograms. Regarding their response to both situations, these cells were grouped into two types. The first type (57%), termed "correlation-sensitive cells", responded with statistically significant difference to correlated and uncorrelated stereograms. The second type responded equally to both stereograms (43%), and therefore they were termed "correlation-insensitive cells". Our data suggest that these two types may form two populations with different functions subserving depth perception.
