conclusion distinct neurochemical and histological structure changes (cortico-striatal-thalamic-cortical cycle) exist in patients with first-episode ocd. 1h-mrs is capable of identifying these changes by assessing metabolic abnormalities. objectives this study aims to use magnetic resonance spectroscopy (mrs) to discover substance-metabolism abnormalities of brain circuits in patients with firs...
Background The basolateral complex of the amygdala receives inputs from neocortical areas, including the medial prefrontal cortex and lateral orbitofrontal cortex. Earlier studies have shown that lateral orbitofrontal cortex activation exerts an inhibitory gating on medial prefrontal cortex-amygdala information flow. Here we examined the individual role of GABAA and GABAB receptors in this proc...
The lateral prefrontal and orbitofrontal cortices have both been implicated in emotion regulation, but their distinct roles in regulation of negative emotion remain poorly understood. To address this issue we enrolled 58 participants in an fMRI study in which participants were instructed to reappraise both negative and neutral stimuli. This design allowed us to separately study activations refl...
The measurement of blood oxygen saturation in the prefrontal cortex (PFC), especially during sleep, is great significance for clinical research. Herein, we present a wearable PFC system using dual-wavelength functional near-infrared spectroscopy. well designed user-friendly donning and has advantages comfort, convenience, portability, affordability. performance proposed investigated by calibrat...
