| Research Abstract |
The following two studies were conducted during this project.
(1) Neural basis of associative face memory: Neural activities in the anterior ventral inferior temporal cortex of monkeys were recorded during the performance of an asymmetrical paired-association task using faces. The results indicated the population of face neurons in this area represents both view-invariant identities of faces and non-facial pictures paired-associated with the identities.
(2) Neural basis of visual search for face: Visual search to detect a face among non-faces were behaviorally analyzed. The results showed that efficient parallel search was observed only for faces of conspecifics. We also recorded neuronal activities in the thalamic pulvinar.
