Summary: The ability to integrate information from different sensory modalities is crucial for neurons in the brain. Integrating visual and auditory cues improves accuracy and speed of behavioral responses. Close-range multisensory interactions typically involve a combination of tactile stimuli with other sensory modalities. Studies have shown that tactile stimuli modulate auditory processing, and there is a strong link between audition and movement.

Summary: This study investigated the possibility of inducing phantom tactile sensations in healthy individuals similar to those observed in stroke patients by manipulating visual feedback. The results showed that under certain conditions, the visual feedback of the reflected right hand in the mirror and tactile stimulation on the left hand could elicit the sensation of touch in the same quadrant as the reflected right hand. The findings suggest a modulation of tactile representation through multisensory integration and body ownership distortion, unveiling bilateral representation of touch.

Summary: Orofacial somatosensory inputs play a significant role in the connection between speech perception and production. Speech motor learning, which involves both auditory and somatosensory inputs, can lead to changes in speech perception. This study demonstrates that repetitive pairing of somatosensory inputs and sounds, similar to those experienced during speech production and motor learning, can also result in a change in speech perception.

Summary: This study shows that during postnatal development, synapses between peripheral mechanoreceptors and central targets in the brainstem undergo developmental refinement, with mechanoreceptors innervating glabrous skin making synaptic connections that expand their central representation. This suggests that the skin region a mechanoreceptor innervates plays a role in shaping the development of its central synapses.

Summary: Texture is perceived through multisensory information. This study found that haptic and auditory exploration activated somatosensory, auditory, and visual cortices, challenging the traditional view. Audio-tactile integration was found in secondary somatosensory (S2) and primary auditory cortices. Multisensory textures are represented in primary areas and S2, which has implications for how the brain processes multisensory cues.

Summary: The study found that in the rubber hand illusion, participants who reported feeling ownership also tended to report touch referral, showing a moderately strong positive relationship between the two. Touch referral was often reported more strongly and frequently than ownership, indicating implications for the experimental paradigm.

Summary: Most prior studies of multisensory integration in autism have focused on audiovisual integration. This study examined bimodal and trimodal integration using reaction times and electroencephalography. The results showed significant multisensory facilitation in both autistic and non-autistic groups, as well as differences in event-related potentials. There were also exploratory findings of group differences in audiovisual interactions.

Summary: The study showed that patients with FND do not exhibit a stronger placebo response compared to healthy controls, suggesting that increased suggestibility to placebo in FND patients may be a misconception. Instead, occasional dramatic placebo responses may occur due to the inherent variability of functional symptoms compared to organic diseases.

Summary: Human perception of touch is influenced by inputs from multiple channels. Contrary to classical theories, it was found that inputs from two sub-modalities of mechanical input channels interact to determine tactile perception. Sustained mechanical pressure was shown to inhibit tingling sensations induced by a bioactive compound, without mediation from nociceptive or affective channels.

Summary: The study explores decision reversals that involve integrating multiple classes of information, such as sensory evidence, higher-order intentions, and motor costs. Movement trajectories reveal when participants change their mind about dot-motion direction and colour choices. Results show that decision reversals about colour intentions are less frequent in participants with stronger intentions and lower motor costs for intention pursuit.

Summary: The study found that in functional tremor, the attentional focus on ongoing visual feedback from the movement is not beneficial and has a detrimental impact on motor performance. This altered attentional focus may partly responsible for functional tremor, and it also worsens motor performance in healthy control participants and patients with an organic action tremor when directed towards visual feedback.

Summary: Reasoning about underlying causal relations influences responsibility judgments, with a preference for pluralistic causal reasoning. Dependence theories and transference theories are two main approaches in causal reasoning, and hybrid models combining both have emerged. Our experiment findings indicate that diminished responsibility judgments occur when dependence, transference, or both fail.

Summary: This paper introduces a non-contact, temperature-controlled, multi-purpose cooling stimulator, which can precisely control the cold sensation stimulation and be used to study different aspects of cold sensation. It avoids the interference of mechanical contact. Through experiments, it is verified that this method can measure the cold detection threshold without mechanical contact, providing a more accurate method for studying cold sensory pathways and cold-touch interactions.

Summary: In cases of rape and sexual assault, victims often experience a state of immobility referred to as 'freezing'. Neuroscientific research suggests that this freeze response is a result of fear and threat, which can inhibit the brain circuits responsible for voluntary movement. Thus, defense arguments that blame victims for freezing are inappropriate and unfair.

Summary: This study investigates the potential differences in processing speed and neural correlates among the three variants of Primary Progressive Aphasia (PPA). The findings reveal that non-verbal cognitive abilities, such as processing speed, are significantly impacted in nfvPPA and lvPPA patients compared to healthy controls and svPPA patients. Neuroimaging results confirm the importance of fronto-parietal regions associated with processing speed and executive control.

Summary: Cholinergic (Ach), Noradrenergic (NE), and Dopaminergic (DA) pathways are crucial in regulating spatial attention and determining inter-individual differences in temperamental traits. This study found that temperamental traits predict individual differences in the ability to orient spatial attention based on the probabilistic association between cues and targets. These findings highlight the importance of considering temperamental and personality traits in social and professional environments where attention control is essential.

Summary: The processing of numerals as visual objects is supported by an Inferior Temporal Numeral Area (ITNA) in the bilateral inferior temporal gyri (ITG). Extant findings suggest some degree of hemispheric asymmetry in how the bilateral ITNAs process numerals. The study found that digit sensitivity did not differ between ITNAs, and digit sensitivity in both left and right ITNAs was associated with calculation skills. The study also revealed a right lateralization in engagement in alphanumeric categorization, and that the right ITNA showed greater discriminability between digits and letters.

Summary: The fiber dissection technique has been used to study the internal structures of the brain, with less focus on white matter. The sagittal stratum, a white matter structure, has not received enough attention and has been a subject of controversy. Recent studies suggest potential functions of the sagittal stratum, emphasizing the importance of understanding this structure accurately.
