Summary: This paper develops a novel method for estimating angular velocity for visually guided flights inspired by the visual neural networks of flying insects. The model, based on elementary motion detectors, successfully reproduces the visually guided flight behaviors of bees in a virtual environment.

Summary: This study develops a control theory framework to study gaze stabilization in fruit flies. By combining experimental and mathematical methods, the role of mechanosensory feedback in head movement control and the motor-context dependent nonlinear gating of mechanosensory feedback are revealed.

Summary: There is a growing interest in using virtual reality (VR) for training and simulations, but presenting haptic cues in VR remains challenging and limits manual interaction. This study examined interaction with a physical touchscreen and a virtual touchscreen in VR, and the effect of auditory cues on performance. Results showed that error feedback improved performance in both touchscreens, but reduced efficiency in VR. Auditory cues improved efficiency in VR but not in the physical touchscreen, possibly due to the tactile and proprioceptive cues provided by the touchscreen.

Summary: Animals move to explore the world, and different brain areas play distinct roles in grasp planning. Sensory object information influences grasp planning, and neural population activity can decode object and sensory modality in a single trial.

Summary: The presence of a visible hand during mirror tracing increased the sensory conflict and resulted in higher alpha and beta power in the somatosensory cortex. Tracing performance was equally impaired by mirror vision in both groups. The increased activity in the visual cortex suggests increased visual processing in response to the sensory conflict. The study demonstrates the importance of proprioceptive information in motor performance and the influence of visual feedback on sensory conflict.

Summary: The extensive sensory inputs, subsequent decision-making, and arm coordination of octopuses complicate traditional motor control system theory. Octopuses reduce control complexity by relying on highly stereotypical motor primitives and multi-level processes. However, the specific arm recruitment and coordination during visually guided reaching behavior are poorly understood. Octopuses exhibit behavioral selection in prey capture, preferring synchronous arm recruitment for striking crabs and sequential arm recruitment for shrimp, aligning with prey escape strategies and arm biomechanical constraints. The second arm is dominant for goal-directed monocular prey capture. Octopuses employ a dimension reduction strategy, actively recruiting adjacent arms during visually evoked prey attack.

Summary: This paper introduces a motion planning framework that combines data-driven policy and local trajectory optimization to achieve safe and socially compliant autonomous driving. By using interactive imitation learning, a model predictive controller is trained and validated in realistic simulated urban scenarios. The approach significantly improves navigation performance and expands the operational domain of the MPC to more realistic autonomous driving scenarios.

Summary: Analyzing visually guided circular tracking movements revealed that using visible orbits with velocity control allowed for more precise tracking compared to invisible orbits. Position information was crucial at low speeds while velocity information of the tracked target could be obtained more precisely at higher speeds. The study also found that feedforward control corresponding to velocity was delayed under visible-orbit conditions at speeds exceeding 0.5 Hz, indicating potential interference with exercise learning when using visually presented 3D guides.

Summary: This paper introduces a color and depth coding scheme for visually impaired individuals to appreciate visual artworks using alternative sensory modalities such as hearing and touch. The proposed system encodes colors like red, orange, yellow, and green with corresponding cues for the visually impaired to understand and interact with visual art on both mobile platforms and 2.5D models.

Summary: Advocates of the dual-stream theory have long defended the idea of two specialized cortical streams for visual processing, but recent evidence suggests overlapping action pathways. This indicates that stored information may have a significant impact on visually guided actions, supporting the notion of skilled automatic actions.

Summary: The physical distance between synaptic Ca2+ channels and sensors modulates short-term plasticity (STP). In Drosophila, synaptic release factors Unc13A and Unc13B distinctly couple with Ca2+ channels and contribute to the neural decoding of distinct sensory information. Reduction of Unc13A weakens responses to different stimuli, while reduction of Unc13B leads to a general shift towards appetitive values.

Summary: Object detection accuracy is degraded in visually degraded scenes. To address this issue, we propose an image enhancement guided object detection method that refines the detection network with an additional enhancement branch. By using the features of enhanced images to guide the learning of the object detection branch, the proposed method improves the detection performance significantly in visually degraded scenes.

Summary: This study focuses on building a model describing atmospheric convection, introducing a visually guided modeling approach that integrates interactive visual parameter space analysis with partial automatic parameter optimization. The method includes a new technique called IsoTrotting, which optimizes the process by navigating along isocontours of the model. The model is evaluated using unique observational data of atmospheric convection based on flight trajectories of paragliders.
