Self-related thought alterations associated with intrinsic brain dysfunction in mild cognitive impairment
Abstract The subjective experience of self-awareness is attributed to the human capacity for introspective thought during periods of mind-wandering. However, how this cognitive function is impacted in individuals with mild cognitive impairment (MCI) still needs to be better understood. To address this gap, we investigated alterations in self-referential thinking in a cohort of 30 MCI patients, comparing them to 60 healthy old-aged and 60 healthy younger controls. MCI patients exhibited a notable decline in overall cognitive function, as evidenced by significantly lower scores on the Montreal Cognitive Assessment (MoCA), with particular deficits in Memory subscore and Memory Index Score (MIS). Employing the Amsterdam Resting-State Questionnaire (ARSQ) to assess mind-wandering, we observed diminished self-related thoughts relating to personal past experiences and future thinking among MCI patients. Notably, using high-density electroencephalography (hdEEG) microstate analysis, we detected reduced neural activity for microstate C associated with self-related thoughts in MCI patients and healthy older relative to healthy younger controls, and an increase in neural activity for microstate A in MCI patients compared to healthy older and younger controls. This aberrant temporal activity was localized within brain regions implicated in episodic autobiographical memory and the default mode network. Our results highlight a link between impaired mind-wandering ability and dysfunction within the intrinsic neural networks of MCI patients, underscoring its implications for disruptions in the sense of self within this clinical population.

Study on the energy characteristics of rocks under cyclic loading and unloading
Abstract The deep-buried rock masses influenced by prolonged geological processes have accumulated vast amounts of energy. This stored energy is released due to disturbances in the external environment, a series of geological disasters is triggered. In this study, triaxial cyclic loading tests were carried out on sandstone and granite at different strain amplitudes to investigate the variation of rock internal energy. Stress–strain curves were recorded under various amplitudes. The calculation model of dissipated energy, elastic energy and plastic energy was established. Energy variations are analyzed to explore the dissipation mechanism of internal energy in rocks. The results show that with the increase of strain ratio, the dissipated energy, elastic energy and plastic energy all increase. When the strain ratio reaches a certain range, the slope of energy increase exhibits a sudden change. The study of the rock failure mechanism from the perspective of energy offers practical and guiding significance for the safety assessment and stability prediction of various geological disasters.
