| Outline of Final Research Achievements |
Humans can remember or attend to multiple moving objects at the same time. The number of objects that can be held in memory or attention is known to be larger when visual stimuli are presented bilaterally rather than presented unilaterally. To elucidate the underlying neuronal mechanism, we trained monkeys with two cognitive tasks; multiple memory-guided saccade task and multiple object tracking task. We found that neurons in the lateral prefrontal cortex exhibited greater activity for bilateral than for unilateral stimuli. Considering the inherent, anatomical separation of contralateral and ipsilateral visual processing, our data might reflect the stronger interaction of mnemonic and attentional signals for multiple objects presented unilaterally than those presented bilaterally.
