D02-9 Neural basis of shitsukan perception tested using image generation with brain activity and implicit behavior
Humans are capable of estimating the material and state of various objects and assigning subjective value and emotions to them through the perception of shitsukan. In the domain of visual shitsukan perception, previous research has elucidated the characteristics of shitsukan perception through the presentation of objects with manipulated shitsukan and the analysis of behavioral and neural responses. While investigating the neural basis directly requires validation using animal models, previous studies using animal models lacked the ability to evaluate the cognitive aspect of shitsukan perception due to the absence of behavioral assessment of shitsukan preferences. In this study, we aim to construct a novel experimental paradigm by employing a preferential gaze task to behaviorally evaluate the natural cognitive states of monkeys while simultaneously generating images based on brain activity and behavioral indices. This approach will contribute to understanding the neural mechanisms underlying shitsukan perception and revealing the specific visual stimuli that elicit rich shitsukan experiences.
