Summary: Human vision processes light and dark stimuli through separate ON and OFF neuronal pathways. At high contrast, dark stimuli are located faster and more accurately, indicating the dominance of the OFF pathway. At low contrast, light stimuli are located faster and more accurately, indicating the dominance of the ON pathway. The correlation between luminance contrast and ON/OFF dominance ratios highlights the importance of contrast polarity in visual field measurements.

Summary: The study investigates accurate estimation of the RF of neuronal populations and its shape, finding that elliptical pRFs are common in the early visual cortex. Researchers also found discrepancies in estimation results using different software packages.

Summary: Stimulus contrast affects spatial integration in the lateral geniculate nucleus, resulting in reduced extraclassical surround suppression and larger preferred stimulus size with low-contrast stimuli. Effects are more pronounced in magnocellular neurons, suggesting stream-specific interactions between stimulus contrast and size. Contrast-dependent effects are comparable in ON-center and OFF-center neurons within the magnocellular pathway, indicating differential interactions between stimulus contrast and size to improve stimulus detection and discrimination under pathway-specific contrast conditions.

Summary: The study revealed that dark disks produce stronger and longer-lasting negative afterimages than bright disks, especially at sizes larger than 0.8 degrees. Neurophysiological recordings showed that subcortical ON cells exhibit stronger sustained post-stimulus responses to dark disks at sizes larger than 1 degree.

Summary: The visual cortex is a heavily studied region in neuroscience due to its well-defined retinotopic organization. Researchers have developed a method to transform retinal objects into their expected representations on the cortical surface without a functional scan. By calculating the product of the retinal object with the cortical vertex's pRF, the expected response of a given vertex to the retinal object can be determined.

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: This study investigates the dynamical behavior of quantum correlations between two identical atoms driven by classical fields and placed in two independent non-Markovian environments. It reveals that the global quantum discord and local quantum uncertainty, as measures of quantum correlations, can be controlled and preserved by manipulating the strength of the classical driving. Further, it demonstrates that the decay process of quantum correlations can be slowed down by adjusting the central frequency of the reservoir.

Summary: Human perception relies on internal representations characterized using reverse correlation, but the method is often inefficient and requires a large number of trials for accurate estimation.

Summary: The study of two CNGA3-achromatopsia adults before and after ocular gene augmentation therapy revealed minor improvements behaviorally and cortically, but color perception still faced challenges either due to insufficient recovery at the retinal level or limitations in processing new cone-derived inputs in the adult cortex.

Summary: The mouse superior colliculus (SC) receives binocular inputs, which inform complex behavioral programs. This study reveals a previously unappreciated diversity of binocularly modulated neurons in the SC through characterizing responses to eye-specific presentations of visual stimuli. This foundational work broadens our understanding of visual processing in the SC and sets the stage for future studies interrogating the circuit mechanisms underlying binocular tuning.

Summary: The development of artificial intelligence poses challenges to conventional machine vision due to its high latency and inefficient power consumption. By gaining insights into the function of each part of the visual pathway and using neuromorphic devices and circuits, machine vision systems can be improved in terms of robustness and energy efficiency.

Summary: An adaptive ensemble perception tracking framework is proposed in this paper to address limitations in traditional tracking models. Through per-pixel prediction and confidence-guided ensemble prediction mechanisms, the algorithm demonstrates superior performance in accuracy and speed compared to state-of-the-art methods.

Summary: This study investigated whether fMRI could be used to determine if perimetrically blind regions of the VF were still represented in VF maps. It was found that the MP approach, compared to conventional pRF modeling, revealed more voxels with retained visual sensitivity in patients with hemianopia. Additionally, the MP-based analysis indicated that both early and extrastriate visual areas contributed equally to the retained sensitivity in both patients and controls.

Summary: The developing visual thalamus and cortex refine connectivity by extracting positional information through synaptic plasticity. However, developing synapses and circuits have evolved mechanisms to compensate for detrimental parasitic correlations.

Summary: This study developed a computational method, PhaseDel, to detect focal deletions and characterize underlying mechanisms in single-cell whole genome sequences (scWGS). The research found that somatic deletions increased with age and in highly expressed genes in human brain. The analysis of DNA repair-deficient diseases with progressive neurodegeneration revealed elevated somatic deletions compared to age-matched controls, suggesting a role for somatic deletions in neurodegeneration.
