Summary: The brain uses both Bayesian and discriminative models of perception during active vision, depending on task requirements (continuous vs categorical) and the source of uncertainty (image noise vs motor-driven noise). Human subjects were found to be Bayesian for continuous judgments but anti-Bayesian for categorical judgments, while macaques showed similar results. This comparative analysis offers insights into the neural organization of the saccadic system.

Summary: The brain interprets sensory inputs to guide behavior, but behavior itself disrupts sensory inputs. Perceiving a coherent world while acting in it constitutes active perception. We tested the hypothesis that the percept of visual stability is Bayesian, and found that priors are used more as sensory uncertainty increases.

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 aim of this study was to assess reading time and fixation characteristics when using progressive power lenses (PPL) with different power distributions at different distances. The results showed that the power distribution of the PPLs affected reading time and fixation characteristics.

Summary: This study investigated the response properties of cerebellar cells in macaques performing synchronized saccades and identified three groups of cerebellar neurons with distinct response profiles. One-third of the neurons were active regardless of saccade direction and showed greater activity for synchronized saccades. The activity of these neurons corresponded to the internal rhythmic structure rather than specific motor commands.

Summary: Research findings suggest impaired saccadic eye movements during walking in individuals with mTBI, but fixations remain unaffected. Future studies should investigate whether saccade outcomes are influenced by the time after the trauma and rehabilitation.

Summary: Different from traditional concept, true colors that can be precisely controlled are obtained by changing the volume fraction deviation. The tunable photonic bandgap varies linearly in the visible region by controlling the volume fraction of two building blocks. The stability of photonic pigments is improved by utilizing the metastable structures of red photonic pigment.

Summary: The study found that subtle changes occur in postural control when performing vertical and horizontal eye movements, with vertical eye movements having less impact on postural sway and greater control at the head level compared to the trunk.

Summary: This study investigates the laminar cortical circuitry underlying attention-associated electric fields in the posterior regions of the brain. The findings suggest that the contribution of each cortical column to the attention-associated electric field depends on the column's feature selectivity. The laminar profile of synaptic activity in visual cortical area V4 is sufficient to produce an attention-associated signal measurable outside of the column.

Summary: The study revealed that contrast sensitivity is significantly reduced in CSCR and strongly correlates with subjective visual impairment. Different structural biomarkers are associated with contrast thresholds reductions at different spatial frequencies.

Summary: This paper discusses the challenges to the transparency and representationalism theses regarding visual experience, analyzing them from a phenomenal perspective of visual noise. Visual noise does not appear to belong to external objects and is not a normal response to specific external properties.

Summary: The perception of depth is influenced by factors such as the adaptation state of the eye and the phase difference between the two eyes.

Summary: The study found that active hand movement did not affect visual depth perception, possibly due to the conflict between hand movement distance and visual depth changes being more easily detected in active movement situations.

Summary: The computational model presented is based on the Active Efficient Coding framework and is capable of developing disparity tuned neurons and precise eye control under normal rearing conditions, as well as reproducing experimental results under altered conditions. The model predicts how altered rearing conditions affect the learning of precise eye control, and also reveals a surprising effect on the statistics of orientation tuning in visual cortical neurons when vergence control is impaired.
