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: 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: A new study in pigeons found that electric fields could transmit attention in a mechanism similar to the superior colliculus in mammals.

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 superior colliculus (SC) is a subcortical brain structure that plays a crucial role in controlling orienting behaviors in nonhuman primates. Recent investigations have revealed the visual pattern analysis capabilities of the primate SC, indicating its importance in guiding orienting movements. Its anatomical proximity to visual inputs and motor control apparatuses, as well as its ascending feedback projections to the cortex, confirm its role in active perception.

Summary: This study investigated microsaccades during free viewing and found that each saccade provides a stimulus-dependent inhibition, similar to the inhibition observed during fixation. In free viewing, microsaccade latency was shorter for more salient stimuli.

Summary: This study measured occipital activity in different spatial regions during the processing of visual displays and found that goal-directed attention and salience jointly modulate activity distribution in the occipital cortex, with involvement of multiple functional paths and interactions.

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 determines the types of cells in the superficial superior colliculus that receive visual input from the primary visual cortex in mice. The results show that all four cell types in the superficial layers of the superior colliculus receive direct input from the primary visual cortex, with wide-field neurons being the most likely to receive this input.

Summary: This study investigates the role and construction mechanism of inhibitory neurons in the barn owl's midbrain in controlling visual perception and attention. The results show that the classical inhibitory surrounds of Imc neurons are inherited from OT, while the extraclassical inhibitory surrounds are constructed within Imc. These findings reveal the key design principles of the midbrain spatial attention circuit and emphasize the critical importance of competitive interactions within Imc for its operation.

Summary: Animals need to pay attention to various stimuli in their environment, with emotional valence and salience affecting how the brain processes information. Horses tend to process negatively valent stimuli using their left eye and right hemisphere, as supported by this study on Italian saddle horses.

Summary: The superior colliculus, or tectum, is responsible for registering events in the surrounding space through various sensory modalities. It forms maps of the space and positions of stimuli, with different sensory inputs arranged in layers. Outputs from the tectum can directly influence motor circuits or be relayed to cortical areas through the thalamus to control behavior.

Summary: We developed a new apparatus and method for automated animal training and discrimination learning using a microcontroller and custom software. This system was used to train and test adult zebrafish in their learning and decision-making abilities. The system minimized human intervention and could be scaled up or down for different species. The software and apparatus provided full experimental control and allowed for precise scheduling and tracking of learning performance.

Summary: This study examines the development of infant attention by evaluating their individual saccades and fixations while viewing different scenes. It found that scanning efficiency is influenced by development, scene content, and complexity. The results show that there are individual differences in saccade rate, mean fixation duration, and saccade amplitude, and that 5-month-old infants make larger, faster, and more frequent saccades compared to older infants. 11-month-olds have high scanning efficiency across all scenes, but scanning efficiency also varies depending on scene content.

Summary: The study found that animals habituate to repeated looming stimuli but not to repeated movement stimuli. Dim stimuli rarely elicit escape responses, therefore cannot habituate. The research also revealed that neither movement- nor dim-sensitive neurons play a specific role in brain-wide visual habituation networks or in behavioral habituation.
