Summary: In this study, a piezoresistor and MoS2 field effect transistor are combined to create an artificial integrated nervous system that can simulate perception and synaptic plasticity. By using the electron trapping-detrapping mechanism at the MoS2/SiO2 interface, the key characteristics of synaptic plasticity are successfully demonstrated through individual and synergy of optical and pressure signals. The perception under the synergy of optical and pressure signals is found to be stronger than perception under individual signals alone, resembling a biological system. In addition, various distinguishable motion scenarios are simulated and verified by adjusting the amplitude and frequency of the optical and pressure signals.

Summary: This study investigated cross-sensory (visual-vestibular) adaptation of self-motion perception. The results showed that even several short-duration stimuli can lead to functional adaptation of perception, suggesting that the brain monitors and adapts to supra-modal statistics of events in the environment.

Summary: Unilateral Vestibular Neurectomy (UVN) leads to persistent postural asymmetry and affects the responses of S1 cortical neurons to skin stimulation, thereby influencing the organizational features of somatosensory cortex. UVN immediately induces an expansion of cortical neuron cutaneous receptive fields, which alters the organization of the somatosensory cortex.

Summary: Accurate self-motion perception is crucial for survival, and it involves multiple sensory cues such as optic flow and inertial motion. Recent studies challenge previous conventional thoughts about the cortical mechanisms underlying visuo-vestibular integration and propose that different temporal component signals may mediate different functions in multisensory self-motion perception.

Summary: This study found that adult rhesus macaques show little neural plasticity in the lower-level multisensory cortical area MSTd, but exhibit neural plasticity in the higher-level multisensory area VIP. The systematic shifts in VIP tuning curves were observed, reflecting the decision-related component of the population response. The results demonstrate neuronal calibration in single sessions, laying the foundation for understanding multisensory neural plasticity in maintaining accuracy for sensorimotor tasks.

Summary: This study aimed to induce the third-person perspective full body illusion (3PP-FBI) in stroke patients using virtual reality. The results showed that synchronous visual-tactile stimulation of a single body part was sufficient to elicit 3PP-FBI in stroke patients, forming a sense of ownership over the entire virtual body. Furthermore, the intensity of 3PP-FBI was stronger when the back was stimulated compared to stimulating the impaired upper limb.

Summary: This study focuses on the contribution of the pulvinar to multisensory integration, suggesting that the pulvinar combines multiple sources of sensory information to enhance fast responses to the environment and acts as a general regulation hub for adaptive and flexible cognition.

Summary: The brain faces the challenge of determining whether sensations of motion have a single cause or multiple causes, integrating vestibular and visual cues for more precise estimation of self-motion. The macaque medial superior temporal area contains neurons that encode combinations of vestibular and visual motion cues, with some responding to congruent cues and others to opposite cues. A neural network model trained for causal inference in motion estimation exhibits both congruent and opposite units, showing the importance of the balance between their activities in determining whether cues should be integrated or separated.

Summary: The study found that people showed a more positive bias towards future self compared with past self and present self, regardless of whether in the first-person perspective or third-person perspective. There was no difference in recognition rate among past self, present self, and future self. Processing of present self in the third-person perspective was more abstract and generalized, possibly reflecting the distancing function of the third-person perspective similar to time.

Summary: The study investigates the flexibility of visuotactile remapping during obstacle avoidance, showing that the location of obstacles can affect the interaction. The results suggest that to-be-avoided obstacles automatically trigger tactile consequences of interaction, extending the understanding of visuotactile remapping in action.

Summary: The study investigates the effects of targeted manipulations of visibility on the subjective and objective aspects of illusory body ownership. The findings suggest that the interaction between rubber hand's visibility and illusory ownership is sensitive to specific subjective ratings but not to objective measurements. The study highlights how relatively abrupt changes in visibility can differentially impact subjective versus objective components of body ownership.

Summary: This study investigated the effects of visual and tactile stimuli on the representation of peripersonal space (PPS) and examined whether the reaction times (RTs) for tactile-only stimuli are influenced by time-dependency effects. The results show that visual and tactile components do not necessarily have to target the same body part, and the RTs for tactile-only stimuli vary depending on the delay of stimulus administration.

Summary: This paper presents the first systematic investigation of single object tracking in First Person Vision (FPV). The study analyzes the performance of 42 algorithms in FPV and finds that object tracking in FPV poses new challenges to current visual trackers. Despite the difficulties, trackers bring benefits to FPV downstream tasks requiring short-term object tracking.

Summary: This study examines the differences in subjective visual vertical and horizontal deviation between unilateral acoustic neuroma patients and healthy young adults under varying degrees of static head tilt. The results demonstrate that patients with acoustic neuroma have higher absolute deviation values compared to healthy individuals, particularly when tilting their heads to the right. The size of the tumor does not appear to be significantly related to the extent of gravity sensing function damage.

Summary: This study aims to expand the temporal self into the domain of the collective self by using an adapted temporal collective self-reference paradigm. The findings indicated that people show positivity bias in trait adjectives judgment, response times, and recognition rates during the temporal collective self-processing, regardless of the perspective considered. This study explores mental time travel on the level of the collective self and contributes to a deeper understanding of the temporal collective self.

Summary: In this study, we investigate the asymptotic stability of a two-dimensional mean-field equation. We show that in the weak connectivity regime, two-dimensional models behave like one-dimensional models, relaxing to a unique stationary state. The proof is based on Harris's ergodic theorem and a perturbation argument adapted to the case of a multidimensional equation with delays.

Summary: We propose a mean-field model of interacting point processes that extends the age-dependent Hawkes processes by incorporating memory of time and leaky memory. The results show that, in the mean-field limit, the empirical measure of the system follows a specific pattern.

Summary: The study introduces a concise model that explains burst states in hippocampal replay through analyzing neural dynamics and provides explanations for noise and slow fatigue mechanisms. The model, derived from the dynamics of neural networks and chemical Langevin equations, along with short-term synaptic depression, effectively simulates the replay process.

Summary: Recent research has focused on the multisensory and neural bases of the bodily self. Direct electrical brain stimulation has revealed specific brain areas that can influence the different components of the bodily self. Stimulation in the parietal cortex can disturb all five components of the bodily self.

Summary: In this work, a recent generalization of population equations for infinitely large networks of spiking neurons to populations of finite size is analyzed. It is shown that the resulting nonlinear stochastic integral equation is well-posed and stable for leaky integrate-and-fire neurons with escape noise and a simplified model. The proof combines methods from Markov processes and nonlinear Hawkes processes, and efficient simulation algorithms are provided for practical applications.
