Summary: The perception of 3D space has been extensively studied, but there are conflicting reports on distortions. This study proposes that 3D perception consists of two processes: perception of traveled space and perception of surrounding space. By testing these two aspects on the same subjects, it was found that the perception of traveled space is experience-dependent, while the perception of surrounding space is not affected by experience. This suggests that these two aspects of 3D spatial perception emerge from distinct processes.

Summary: The research report introduces a brain-inspired general place recognition system called NeuroGPR, which enables robots to recognize places in natural environments by mimicking the neural mechanism of multimodal sensing, encoding, and computing. The system utilizes a multimodal hybrid neural network to encode and integrate cues from different sensors, and a multiscale liquid state machine to process and fuse the information. Experimental results show that NeuroGPR performs well in various environmental conditions.

Summary: The hippocampus is known to play a significant role in spatial navigation in rodents and bats. However, studies on the spatial behavioral correlates in the primate hippocampus, including humans, are limited. Recent research on freely-moving primates has shown differences in spatial representations compared to rodents. This review examines empirical studies on the neural correlates of spatial navigation in the primate hippocampus, including local field potentials and single units.

Summary: In a study using virtual mazes, participants were able to find the shortest route between remembered objects even in physically impossible environments, suggesting the use of a graph-like representation of space. The factors influencing junction choices differed in physically impossible versus physically realizable mazes, indicating that the complexity of the maze may dictate which factors are more important in influencing navigational choices.

Summary: Research indicates that human navigation behavior in spatial environments typically follows Euclidean principles, even when curvature violations are present. Experimental results demonstrate that individuals' navigation responses tend to assume Euclidean geometry, even in non-Euclidean environments.

Summary: This study compared cognitive map formation in small-scale models of city-like environments presented in visual or tactile/haptic modalities, finding no distinct advantage of vision over haptic in the simple maps. The results support the idea of modality-independent representations of space.

Summary: This research explores the relationships between the way virtual space is explored, the perception of presence, and the degree of entertainment experienced. The study reveals two types of exploratory behaviors - interface dependent and interface independent, which have different effects on the perception of presence and entertainment.

Summary: Virtual Reality (VR) is a popular technology with the rise of consumer displays and commercial platforms. However, rendering synthetic imagery with low latency and high quality is challenging, especially for VR applications with high field-of-view and stereoscopic viewing. This paper presents a gaze-contingent 3D neural representation and view synthesis method to address these challenges. The approach incorporates human psychophysics and optimizes latency/performance and visual quality to achieve perceptually high-quality immersive interaction. Objective and subjective evaluations show that the method significantly reduces latency without compromising rendering quality, making it a promising step towards real-time VR/AR systems.

Summary: The study found that the visibility of destinations and the continuity of sight-lines along the vertical dimension can impact unaided and goal-directed wayfinding behavior in a multilevel desktop Virtual Reality study. Once the destination is in sight, participants immediately decide to switch floors and move upwards towards the destination. However, if the destination is out-of-sight, participants engage in 'visual exploration', characterized by increased vertical head movements and longer time taken to switch floors.

Summary: Grid cells in the medial entorhinal cortex play a crucial role in processing both spatial and social information. The study found that grid cells exhibit rate remapping in response to social conditions and undergo global remapping when the spatial landmarks change. Furthermore, the results suggest that grid cells respond to spatial and social information through different mechanisms.

Summary: The study found that in virtual reality navigation, walking and running in place resulted in more involuntary position shifts compared to joystick and teleportation, which could lead to safety issues. Although teleportation had the shortest task completion time, its error time ratio was the highest.

Summary: Substantial progress has been made in embodied visual navigation based on RL, but the presence of interactable objects in real cluttered scenes poses a challenge for the ego-centric visual agent. To address this, the authors propose a transformer-based memory to empower agents with historical interactive information and utilize a surrogate objective to predict the next waypoint, facilitating representation learning and bootstrapping RL.

Summary: Ku et al. recorded activity in the entorhinal cortex (EC) and hippocampus (HPC) of macaques during associative learning tasks to test the computational model prediction of their role in error-driven learning. They found that the EC and HPC have prominent but differential contributions to learning from errors, with the EC playing a particularly important role in error-detection.

Summary: People tend to selectively trust others based on their appearance, and regardless of facial morphology, observers unconsciously increase the contrast of the eye area to make a face appear more trustworthy. Attraction judgements, however, depend on cultural processes.

Summary: How do differences in visual perception between rodents and primates affect the brain's construction of egocentric and allocentric reference frames for representing stimuli in space? While there are notable similarities in the egocentric spatial reference frames used by cortical regions in both rodents and primates, the representation of allocentric place appears to be more important in the primate hippocampus, which is linked to the first-person perspective of a primate's field of view. Additionally, an allocentric reference frame is suggested to be a semantic construct in primates, possibly related to conceptual framing. Finally, the use of views, based on a first-person perspective, can effectively probe episodic memory across species.

Summary: Digit-tracking is a simple and calibration-free technique that can be used as an alternative to eye tracking in vision science. This system records finger movements on a touchscreen to measure eye movements and attentional focus. The results obtained using digit-tracking were comparable to those obtained using eye-tracking, supporting its validity and relevance for vision and attention research.
