Abstract Successful navigation relies on the ability to identify, perceive, and correctly process the spatial structure of a scene. It is well known that visual mental imagery plays a crucial role in navigation. Indeed, cortical regions encoding navigationally relevant information are also active during mental imagery of navigational scenes. However, it remains unknown whether their intrinsic activity and connectivity reflect the individuals’ ability to imagine a scene. Here, we primarily investigated the intrinsic causal interactions among scene-selective brain regions such as Parahipoccampal Place Area (PPA), Retrosplenial Complex (RSC), and Occipital Place Area (OPA) using Dynamic Causal Modelling (DCM) for resting-state functional magnetic resonance (rs-fMRI) data. Second, we tested whether resting-state effective connectivity parameters among scene-selective regions could reflect individual differences in mental imagery in our sample, as assessed by the self-reported Vividness of Visual Imagery Questionnaire (VVIQ). We found an inhibitory influence of occipito-medial on temporal regions, and an excitatory influence of more anterior on more medial and posterior brain regions. Moreover, we found that a key role in imagery is played by the connection strength from OPA to PPA, especially in the left hemisphere, since the influence of the signal between these scene-selective regions positively correlated with good mental imagery ability. Our investigation contributes to the understanding of the complexity of the causal interaction among brain regions involved in navigation and provides new insight in understanding how an essential ability, such as mental imagery, can be explained by the intrinsic fluctuation of brain signal.

Combined Lesions

The dorsal bank of the superior temporal sulcus (STSd) bears anatomical relations similar to those of perirhinal cortex, an area critical for visual recognition memory. To examine whether STSd makes a similar contribution to visual recognition memory, performance on visual delayed nonmatching-to-sample (DNMS) was assessed in rhesus monkeys with combined or separate ablations of the perirhinal cortex and STSd as well as in unoperated controls. Consistent with previous findings, ablations of perirhinal cortex produced deficits nearly as severe as that found after rhinal (i.e., entorhinal plus perirhinal) cortex lesions. However, combined lesions of perirhinal cortex and STSd produced a deficit no greater than that produced by perirhinal cortex ablation alone, and lesions of STSd alone were without effect on DNMS. We conclude that STSd is not critically involved in visual recognition memory.
