| Outline of Final Research Achievements |
The visual area V4 of macaque monkeys is located at the mid-tier stage of information processing stream on object appearance. V4 neurons selectively modulate their response to moderately complex visual features such as curved lines and texture. To examine visual response properties of multiple nearby neurons in V4, we demonstrated the combination of in vivo 2-photon calcium imaging and encoding model analysis. The technique could elucidate response properties of more than 100 nearby neurons recorded simultaneously for one hour.
