Summary: Neuronal differentiation is regulated by neuronal activity. The dendrites and axons of BCs and non-BCs were analyzed, and it was found that AcDs were the most complex dendrites in both cell types. The configuration of AcDs influenced the development of BC axons, while non-BCs' axons did not respond to the AcD configuration. The results suggest that the formation of dense BC plexuses is regulated by spontaneous activity and the growth of AcDs and their axons mutually support each other.

Summary: This study investigates the process of perceptual decision-making in Drosophila and finds that the rate of accumulation of sensory evidence is related to the synaptic integration of neurons at the decision threshold. By comparing different models, the study concludes that the temporal integration mechanism of neurons can explain the accumulation of sensory evidence, and optogenetic stimulation can accelerate the decision-making process at the cost of reduced accuracy.

Summary: Epithelial cell properties are determined by the polarized distribution of membrane lipids, the cytoskeleton, and adhesive junctions. Little research has been done on how neurites affect epithelial organization. This study found that axon endings in basal keratinocytes remodel cell membranes, cytoskeleton, and junctions, and regulate epidermal adhesion by organizing lipid microdomains.

Summary: During the development of the visual cortex, a balanced enhancement of excitatory and inhibitory synaptic inputs plays a crucial role in the enhancement of visual responses and maturation of visual receptive fields (RFs). The strengthening of excitatory inputs and broadening of inhibitory subfields are key factors in the development of visual cortical RFs.

Summary: This study compared temporal integration against non-integration strategies and found that temporal integration is a common feature in perceptual decision-making tasks. Evidence from behavioral data and statistical analysis supported the existence of temporal integration.

Summary: The ability to move introduces animals with the problem of sensory ambiguity. This ambiguity can be resolved through changes in neural response gain. The study found a systematic distribution of population eye-position dependent gain fields, suggesting that signals beyond retinotopy are accessible in the early visual hierarchy, providing potential to solve sensory ambiguity and optimize sensory processing information.

Summary: This study reveals the diversity and stereotyped tuning of neural representations in the dorsal and ventral areas of the mouse visual cortex, indicating the presence of parallel processing channels and streams. Furthermore, the study uncovers the specialization of different cortical areas for distinct perceptual features and spatial abilities.

Summary: Antagonistic interactions between center and surround receptive field components are crucial in visual computations. We found that bipolar cells enhance responses to objects in their receptive field and show altered dynamics during continuous motion.

Summary: We present an improved solution to the neural image-based rendering problem, which can synthesize realistic images of a scene from different perspectives. The key ideas include recovering accurate camera parameters, modeling object's content at different resolutions, and leveraging scene rigidity and single-image depth prediction. Extensive experiments demonstrate the suitability of our approach.

Summary: Contrary to current theories, this study shows that the visual system has access to extra-retinal knowledge of eye motion and uses it to deduce spatial relations, enabling humans to perceive a stable visual world despite the constant motion of their eyes.

Summary: Rapid response to visual stimuli is crucial for survival and predation among animals. Male Eristalis tenax hoverflies possess unique descending neurons with dual receptive fields that respond to different visual stimuli, allowing for efficient target pursuit and capture. These findings shed light on the neural mechanisms underlying rapid visual processing in insects.

Summary: Classification and recognition tasks on photonic hardware-based neural networks often require an offline computational step, but removing this step can improve response time and energy efficiency. We present numerical simulations of different algorithms using ultrafast photonic spiking neurons as receptive fields for image recognition without offline computing. We discuss the merits of event, spike-time, and rank-order based algorithms adapted to this system, which can significantly improve the efficiency and effectiveness of optical classification systems.

Summary: The study found that human observers were able to quickly learn cross-species expressions, indicating that face dynamics are largely represented independently of facial shape. This result supports the co-evolution of visual processing and motor control of facial expressions, while challenging appearance-based neural network theories of dynamic expression recognition.

Summary: This study provides an immunohistochemistry-based anatomical map of all innexin gap junction proteins in the central nervous system of Drosophila melanogaster. The expression of these proteins is found in glial cells as well as neurons, with shakB being the most widely expressed computation for direction selectivity.

Summary: In this study, it was found that smoothness of neural responses can achieve both efficiency and robustness in the processing of dynamic visual stimuli in hierarchical brain structures. This implies the preservation of the structure of visual environments in neural responses. Therefore, balancing efficiency and robustness is crucial in neural coding for visual processing.
