dc.description.abstractDuring natural vision, we rarely see objects on their own but rather within rich and complex environments. Understanding how the brain recognizes objects in these natural scenes by using contextual information remains a significant challenge. To explore neural mechanisms similar to human visual processing, it is crucial to have an animal model that behaves like humans. This way, the neural mechanisms we identify can offer insights relevant to the human brain. In this study, we investigated whether rhesus macaques could serve as a model for human context-driven object recognition. We did this by measuring their ability to identify visual objects with varying amounts, quality, and congruency of contextual cues. Our behavioral metrics showed remarkably similar context-dependent patterns between humans and monkeys. However, neural responses in the inferior temporal (IT) cortex of monkeys, who were not explicitly trained to recognize objects in context, could only partly explain this cross-species similarity. The behavioral similarities that were not explained by context-naive neural data highlight significant gaps in our understanding. Our findings reveal a fascinating alignment between human and monkey visual object processing that cannot be fully explained by neural activity in a key visual region.
