Summary: The approximate number system (ANS) is an innate cognitive system that allows humans to perceive numbers (>4) in a fuzzy manner. It is believed that numerosity is represented amodally by filtering out nonnumerical information. However, this study found that spatial information from haptic stimuli influenced the accuracy of a number matching task. Results showed that spatially identical patterns and congruency between haptic and visual stimuli improved performance, challenging the assumption that numerosity is represented in an abstract manner.

Summary: The study investigates the neural mechanisms underlying probabilistic inference in the human brain using EEG. The researchers found modality-specific signatures of mismatch responses and a common cross-modal signature in the P3a time range. The observed dynamics were best explained by Bayesian learning models.

Summary: This paper presents a new computation framework for conducting reliability-based design of underground constructions involving geo-material uncertainties, utilizing a simplified inverse first-order reliability method. The results show that blowout failure of tunnel face is extremely unlikely in sandy soil stratum, while collapse is the only possible failure mode. The coefficient of variation of internal friction angle has a greater influence on the tunnel face failure probability than that of the cohesion in geotechnical uncertainties.

Summary: This study investigated the difference in audiovisual emotional integration between depressed and non-depressed college students. The results showed differences in crossmodal emotional processing mechanisms between the two groups, with the depression group exhibiting larger amplitudes in several brain areas and significantly lower LPP amplitudes in the frontocentral lobe compared to the normal group.

Summary: The standard processing of airborne gamma-ray spectrometry data is helpful in various fields, but considerations of flight height and overlap area are crucial. Inversion algorithm can calculate concentration to address data errors, and a logarithmic barrier approach can prevent negative values. Testing shows that the inversion method is more consistent with survey data.

Summary: This study used computational modeling to investigate cognitive flexibility in reversal learning in children and adolescents, finding that children make more errors and regressive errors, but less perseverative errors compared to adolescents. The study also revealed differences in how children and adolescents utilize new information to update their stimulus-reward associations.

Summary: Studies show that mice can solve complex orientation discrimination tasks with choices decoupled from individual stimuli orientations. They also demonstrate typical discrimination acuity of 9 degrees, challenging the common belief that mice are poor visual discriminators. These findings suggest that mice are a useful animal model for studying neural representations of relative categories in perceptual decision-making research.

Summary: The primary challenge in biological sciences is to control gene regulatory networks (GRNs) to create therapeutic intervention methods. Optimal control of GRNs using probabilistic Boolean control networks (PBCNs) addresses this challenge by scaling to large systems without limiting network dynamics. Utilizing GPU and information-theoretic approach, the study developed optimal control for PBCNs in the Markovian framework, with a transformation to a linear problem for computation of optimal control using the path integral (PI) method and sampling-based methodologies for approximation and optimization.

Summary: This article introduces an optics-based approach for underwater image restoration. By considering attenuation coefficients and global light as latent variables, a factorial Markov random field is used to reformulate and solve the general nonlinear participating media optical model. Experimental results demonstrate the effectiveness of this approach in improving degraded images in various scenarios.

Summary: Fearful faces intruding into peripersonal space can increase the redirection of sensory resources towards the periphery, while this effect is almost absent in neutral faces. Electrophysiological results also suggest that the fear-induced effect of fearful faces in near space enhances the expectation of peripheral visual events.

Summary: Seeing the speaker's face improves speech understanding in noisy environments due to the brain's ability to integrate audio and visual information. Selective attention plays a crucial role in our understanding, but how attention and multisensory integration interact during natural speech remains unclear. Using EEG data, we found evidence for multisensory integration of attended audiovisual speech and suppression of integration for unattended speech. Early integration occurred for unattended speech, but not at later processing levels. These findings suggest that natural audio and visual speech integration happens at multiple processing levels and is influenced by attention.

Summary: The study investigated whether multisensory learning can be based on high-level feature congruency without perceptual congruency, and how this relates to changes in brain function and behavior. The results suggest that multisensory learning is potentially based on high-level features without perceptual congruency, and involves neural representations of stimulus features involved in learning.

Summary: The perception of vertical relies on vestibular and visual cues. This study found that sustained exposure to panoramic and vestibular cues has a local effect on the subsequent perception of vertical, which is mediated by head orientation.

Summary: This study proposes that the somatosensory system may implement multilateration to decode touch location on the body by estimating the relative distance between afferent input and body part boundaries. A simple feed forward neural network was shown to be able to implement this computation, and the computational signature of multilateration was identified in psychophysical experiments.

Summary: The study suggests that information from different sensory modalities can be integrated to improve perceptual precision. Both adults and adolescents tend to bias their localization towards the visual stimulus when presented with visual and tactile stimuli, especially when the stimuli are presented close to each other.

Summary: Referential pointing, a simple communicative behavior, is cognitively complex as it requires communicators to consider addressees' knowledge. This study examines how communicators' inferences about addressees' mental representation of the interaction space influence sensorimotor control of referential pointing. The findings suggest that participants generate communicative behaviors as required and integrate communicative and perspective-taking information hierarchically during sensorimotor control.

Summary: Behavioral studies have shown that humans take into account the effect of inertial acceleration on hand choice during body motion. This study used transcranial magnetic stimulation to investigate the integration of body motion information with hand selection. The results indicate that corticospinal excitability is influenced by body motion, suggesting that information about body motion deeply penetrates the motor system.

Summary: The study examined the development of online reach control in infants aged six and eleven months. Infants reached for a toy while their hand position was tracked, and the toy was either stationary or unexpectedly displaced during the reach. The results showed that both age groups adjusted their reaching movements in the direction of the displacement, but the 11-month-old infants made adjustments within a single movement unit while the 6-month-olds required multiple movement units. This suggests that the reach control system develops a rudimentary replanning capacity by 6 months of age, which further develops into a more sophisticated mechanism by 11 months.

Summary: Contemporary motor control theories propose competition between multiple motor plans before the winning command is executed. This study shows that muscle activity during immediate response reach task is influenced by the nonchosen target and reveals different phases of directionally tuned activity, indicating an evolution in how the nonchosen target influences muscle activity.
