Summary: The mammalian vestibular efferent system remains a mystery, as it does not relay inputs from other sensory modalities or motor-related signals to the vestibular periphery, but likely plays a key role in calibrating and protecting vestibular circuits during development and aging.

Summary: This study recorded action-induced somatosensory omission responses using EEG in humans and found that these responses may reflect prediction errors at multiple levels in the brain.

Summary: Neural replicas of the spinal motor commands play an important role in producing gaze-stabilizing eye movements and have been conserved during vertebrate evolution. They provide estimates of the sensory consequences of behavioral action and can counteract the perturbing effects of self-generated head/body motion.

Summary: The article discusses the phenomenon of tactile suppression, where tactile sensations on a moving hand are perceived weaker compared to a stationary hand. It presents evidence that tactile suppression is specifically tuned to predicted sensory states of a movement, supporting the role of precise sensorimotor predictions in this phenomenon.

Summary: This study found that training humans to control a self-motion platform leads to the construction of an accurate internal model that maps steering movements to vestibular signals. It demonstrates that vestibular feedback allows for both online control and rapid adaptation to gain changes.

Summary: Efference copy-based forward model mechanisms help distinguish between self-generated and externally-generated sensory consequences. This study examined visual stimuli following active and passive button presses and found that there was suppression of early visual responses in the active condition, and this suppression was correlated with the suppression of the visual P2 component. These findings support the idea of efference copy-based forward model predictions in the visual sensory modality.

Summary: Accurately controlling posture and spatial orientation during self-motion requires integration of vestibular and neck proprioceptive inputs. The anterior vermis of the cerebellum is believed to play a crucial role in transforming sensory information into an estimate of body motion. The response dynamics of Purkinje cells in the anterior vermis show heterogeneity and they encode an intermediate representation of self-motion between head and body motion. This heterogeneity is proposed to underlie the cerebellum's ability to compute the dynamic representation of body motion for postural control and perceptual stability.

Summary: The study found that disturbances in self-other distinction in schizophrenia spectrum disorders are particularly driven by agency, while self-other distinction based on hand identity might be spared.

Summary: This study evaluated the prevalence of individual and multiple sensory impairments among older adults and found that hearing and visual impairments were the most common co-occurring deficits. Combined hearing, vision, and olfactory impairments were more likely to co-occur than expected, especially in older age groups.

Summary: Self-induced pain can be predicted and downregulated by a copy of motor information from the body's own movement. This phenomenon, known as sensory attenuation, allows for differentiation between self-produced stimuli and stimuli produced by others. The study shows that sensory attenuation occurs during both self-induced pain and imagery of self-induced pain, with potential clinical implications for pain management in patients with self-injury behavior or chronic pain conditions.

Summary: This study investigated the contribution of cervical proprioception, vision, and vestibular feedback to the dynamic head-trunk orientation error in the yaw direction. The results showed that dynamic cervical proprioception is the most significant sensory modality for reducing the dynamic head-trunk orientation error.

Summary: In this study, we investigated the effects of prolonged exposure to a delay between an action and the generated sensation on sensory attenuation for self-touch. We found that after systematic exposure to a delay, artificially delayed touch can feel more intense and non-delayed touches can appear less intense. Furthermore, our data show that the temporal selectivity of sensory attenuation of self-touch depends on presenting a singular test delay only.

Summary: The study investigates whether attenuation due to self-initiated sounds affects motion-onset response, finding that the attenuation is not dependent on congruency between action and sound motion direction.

Summary: The study found that there were motor-related signals in flying Drosophila during flight turns, but these signals were weak or non-existent when turning in response to brief pulses of unidirectional visual motion. This suggests that the initiation of a locomotor act can affect the modulation of visual processing.
