Summary: The superior colliculus in the brain is a crucial visual processing station that receives input from various types of retinal ganglion cells. Through recording mouse superficial SC neurons, we identified 24 functional types using an unsupervised clustering algorithm. These types can be grouped into two categories: one that responds similarly to retinal ganglion cells and another with more diverse and specialized stimulus selectivity. Cells of the same functional type tend to cluster together in anatomical space, and the visual representation in the SC has lower dimensionality compared to the retina, suggesting a sifting process along the visual pathway.

Summary: The superior colliculus (SC) is capable of recognizing and categorizing emotional features from retinal information, independently of additional processing in the visual cortex or limbic areas. The SC model exhibits similar error patterns to humans and shows preference for specific visual features and processing pathways.

Summary: The primate superior colliculus plays a crucial role in small eye movements and visual processing, particularly at the foveal scale. It integrates visual and movement signals, regulates eye positioning and microeye movements, while also showing sensitivity enhancement and suppression effects in the periphery.

Summary: This study aims to identify the safety envelopes of vehicle-pedestrian conflicts by analyzing pedestrian active avoidance behavior in virtual reality-based emergent traffic scenarios. The research reveals the general perception-decision-action mechanisms under external stimuli, showing that pedestrians can avoid collisions by adapting walking speeds and directions.

Summary: The aim of this study was to investigate the involvement of the mesencephalic superior colliculus (SC) in the pathogenetic mechanism of SIDS. In-depth neuropathological investigations showed alterations in the laminar arrangement of the SC deep layers in 69% of SIDS cases, but never in the controls. These SC anomalies represent a new step in understanding the pathogenetic process of SIDS.

Summary: The superior colliculus has long been associated with the control of eye movements, but recent studies suggest it may also be involved in more complex movements such as skeletomotor muscle group coordination and whole-body movement sequences.

Summary: The study shows that mice can make sensory-guided gaze shifts involving both eye movements and attempted head movements. The flexibility of mouse gaze shifts is revealed under head-fixed conditions, offering insights into the characteristics of mouse gaze shifts and laying the foundation for studying the coupling between head and eye movements.

Summary: Animals rely on vision to perceive threat information, and the superior colliculus and lateral posterior nuclei are key components in the subcortical visual pathway. Research shows that these nuclei strongly respond to looming visual stimuli but are not sensitive to dimming visual stimuli. Under looming visual stimuli, there are evident oscillations in the theta frequency bands of these nuclei, enhancing synchronization between neurons and improving information transmission efficiency.

Summary: This study investigates the relationship between changes in size and complexity of familiar objects and the exploratory activity regulation in rats. The rats responded to new tunnels with increased exploration, initially reacted to changes in size but then refocused, and showed pronounced curiosity towards increased complexity. The data suggests that curiosity in rats is at least two-dimensional: activational and cognitive.

Summary: Internal state profoundly impacts perception and behavior, with a fluid and ill-defined definition. An integrative framework centered on dynamic and interconnected communication loops between body and brain offers a way to understand internal state, potentially uniting disparate paradigms used by scientists studying body-brain interactions.

Summary: In this paper, an effective bio-inspired active learning method is proposed to reduce the training cost of deep SNN models. By defining bio-inspired behavior patterns and leveraging sample selection strategies, the proposed method optimizes behavioral patterns and achieves state-of-the-art performance in SNNs.

Summary: The study reveals a coordination between the orexin system and the rodent superior colliculus across the day-night cycle, with orexin input predominantly occurring nocturnally and the SC neurons responding to orexin A and exhibiting circadian expression of clock genes.
