Summary: This study found that SG-P50 deficit may be an informational biomarker for depressive symptoms and neurocognitive impairments in FEAN-SCZ patients. For depressive FEAN-SCZ patients, the S2 amplitude of SG-P50 may serve as an independent predictor of MCCB-Mazes (NAB).

Summary: This study discovered and characterized P50 dynamic brain connections using microstate analysis. The results suggest that deficits in P50 suppression in schizophrenia may be attributed to abnormal baseline sensory perception and adaptation. This finding provides new insights into the mechanisms of P50 suppression in the early stage of schizophrenia.

Summary: This study found that individuals with schizophrenia exhibit poorer sensory gating, particularly in the A1 region, as well as in adjacent brain regions. In addition, the study suggests that endogenous connectivity evident in a sequence of activity from angular gyrus to portions of superior temporal gyrus may contribute to both normal and abnormal gating in schizophrenia.

Summary: The study investigates the relationship between sensory gating deficits, childhood trauma, and schizophrenia onset. It is found that patients with first-episode schizophrenia have more severe childhood trauma experiences and sensory gating deficits. Sensory gating deficits might mediate the effects of childhood trauma on the onset of schizophrenia.

Summary: Auditory gating (AG) is an adaptive mechanism for filtering out redundant acoustic stimuli to protect the brain against information overload. The posterior parietal cortex (PPC) shows an intermediate level of AG in auditory thalamocortical circuits, with the strongest AG in the granular layer. AG in the PPC is determined by the integrated signal streams from the medial dorsal thalamic nucleus (MD) and auditory cortex (AC) in a bottom-up manner. A mouse model of schizophrenia (SZ) presents an AG deficit in the PPC, possibly inherited from the dysfunction of MD.

Summary: This study aimed to investigate the relationship between serum level of kynurenine pathway (KP) metabolites and P50 auditory gating in patients with first-episode schizophrenia. The results showed significant associations between metabolite levels and auditory gating, suggesting that the KP might play an important role in sensory gating deficit in schizophrenia.

Summary: The study found that sensory gating was related to positive and disorganized dimensions, smooth pursuit eye movement error was related to negative dimensions, while latent inhibition and prepulse inhibition were not related to any dimensions of schizotypy. These results suggest that the symptom clusters associated with different endophenotypes are largely independent of each other.

Summary: This study investigated the potential of P50 sensory gating and prepulse inhibition ratios as surrogate markers for cognitive fatigue in people with multiple sclerosis (pwMS). The results showed that P50 sensory gating was correlated with subjective fatigue ratings. This study is the first to demonstrate fatigue-related disruption of sensory gating in pwMS.

Summary: This article investigates the role of presynaptic inhibition in proprioceptive signals and finds that it can modulate proprioceptive input based on muscle length. This presynaptic inhibition may be initiated by cortical signals and has an impact on stable motor output.

Summary: This study found that a subanesthetic dose of the NMDAR antagonist ketamine impaired auditory sensory gating, providing further evidence for the role of NMDAR hypofunction in schizophrenia.

Summary: This study sheds light on a possible mechanism for modulating cortical population activity by gating in response to sensory stimuli. Through observations in the mouse auditory cortex and brain slice experiments, a cortical-thalamocortical-thalamic reticular nucleus circuit was implicated in modifying thalamic synchronization to recruit cortical neuron populations for sensory representations.

Summary: The study found enhanced cortical responses in somatosensory evoked potentials (SEP) in patients with amyotrophic lateral sclerosis (ALS), with no significant differences in sensory gating between patients and controls. The baseline amplitudes of certain components of SEP were significantly correlated with their gating ratios in ALS patients, indicating preserved sensory gating in the early stages of the disease.

Summary: This study investigated the impact of smoking cessation with varenicline on the serum concentration of olanzapine in patients with Schizophrenia. The results indicated that olanzapine concentrations increased nonlinearly in both the varenicline and placebo groups over the 12-week study period, but there was no significant difference between the two treatment groups.
