Summary: This study investigates how individuals represent the front and back space based on sound stimuli. It finds that the evaluation of stimulus distance and blink response are better explained by subjective front-back discrimination rather than the actual position. These findings suggest that the mechanisms involved in blink response magnitude may also affect sound localization, and there is a close relationship between bottom-up and top-down mechanisms in spatial representation.

Summary: This study investigated the effects of low-intensity prepulse inhibition (PPI) to digital nerves and conditioning supraorbital nerve stimulation (SON-1) on blink reflex (BR) excitability recovery (BRER) to paired supraorbital nerve stimulation (SON-2). The results showed that PPI did not affect BRER, but inhibition on BR to SON-2 was observed when additional prepulses were applied before SON-2. The study concluded that the response size of BR to SON-2 depends on SON-1 stimulus intensity, not SON-1 response size.

Summary: Through computational predictions and neurophysiological assessment, it was found that monopolar multi-electrode tDCS can selectively affect deep brain structures and brainstem neural circuits. These findings may contribute to further applications of non-invasive deep brain stimulation.

Summary: The study found that patients with NREM-sleep parasomnia showed mildly enhanced ASR and relatively early facilitation of BR excitability during daytime. Analysis of ASR and other reflexes revealed differences between patients and healthy subjects. Although the results suggest involvement of brainstem networks in NREM-sleep parasomnia during wakefulness, further research may be needed.

Summary: The modulation of the blink reflex can be observed in both self-stimulation and external stimulation, showing similar changes in R2 and R1. However, self-stimulation has a tonic effect on the blink reflex, while external stimulation has a time-locked gating mechanism at the brainstem level.

Summary: The hand-blink reflex is a subcortical response that is elicited by electrical stimulation of the median nerve. The magnitude of the reflex is enhanced when the stimulated hand is close to the face and is modulated by high-level structures based on the perceived threat magnitude. Psychological factors, such as personality traits and anxiety, may contribute to the modulation of the reflex. In this study, emotional and relational aspects of personality were evaluated and found to be associated with the hand-blink reflex response in healthy subjects.

Summary: Thin-ideal internalization may represent a higher-order factor contributing to the relationship between reactions to food and eating disorders, while higher levels of eating pathology are negatively correlated with appetitive responses.

Summary: Electrodiagnostic methods can reveal the functional state of nerves in patients with large vestibular schwannomas and provide a basis for objectively evaluating nerve injury. They are particularly useful in assessing trigeminal and facial nerve injuries.

Summary: This study investigates the role of pain-modulatory brainstem pathways in complex regional pain syndrome (CRPS) and reveals altered habituation of the nociceptive blink reflex (nBR) as a potential diagnostic biomarker. Patients with CRPS showed a significant decrease in habituation on both the stimulated and non-stimulated side. This is the first study to demonstrate the pathophysiological mechanism and diagnostic potential of altered nBR habituation in CRPS.

Summary: The study showed that stimulation of the pedunculopontine tegmental nucleus (PPTg) can increase latency and decrease duration, amplitude, and area of the R2 component of blink reflex, regardless of the side of supraorbital nerve (SON) stimulation. The effects were stable for interstimulus intervals (ISI) between PPTg prepulse and SON stimulus.

Summary: This study explores the relationship between eating disorders and motivational responses, finding that binge eating may be associated with increased reward reactivity while restrictive eating may be linked to decreased reward reactivity or increased threat. The research also indicates that eating pathology group did not predict motivational reactions to food, and rating low-calorie foods lower on craving was associated with endorsement of restrictive eating.

Summary: This retrospective study examined prognostic factors and recovery time in Bell's palsy patients receiving different doses and durations of oral glucocorticoid treatment. Favorable outcomes were associated with delayed blink reflex and high fENoG values. Shorter recovery times were linked to younger age (<60), delayed blink reflex, and fENoG values >33%.

Summary: Tinnitus is a prevalent auditory disorder with poor treatment options. The underlying causes of tinnitus are still not well understood, but recent research suggests a strong neurocognitive component. To accelerate progress in the field, researchers have developed a novel tinnitus-verification technique using rhesus monkeys and tested its applicability in human tinnitus patients. The results demonstrate the potential of this technique for objective measurements of tinnitus in humans and routine tinnitus testing in animals.

Summary: In this study, three hypotheses about the extension of peri-personal space after tool-use training were investigated using a visual target detection task: Addition, Extension, and Projection hypotheses. The target detection performance was compared before and after tool-use training, in which participants held a hockey stick-like tool in their hands. Additionally, a no-tool-holding condition was added to the experimental design. The results showed that there was a peri-hand space advantage in the visual target detection task in the no-tool-holding condition, which was lost when participants held the tool. After tool training, a peri-tool space advantage was observed, but the advantage of the peri-hand space was not observed.

Summary: The study showed that the magnitude of hand blink reflex (HBR) increases in the peripersonal space (PPS) when a threatening stimulus is visible, and in the eyes closed condition the reflex had shorter latency and smaller area under the curve compared to the eyes open condition.

Summary: Brains that work together synchronize and may facilitate social interaction. Studying this phenomenon requires multibrain stimulation rather than just recording brain activity. Promising findings and future horizons in this field are highlighted.
