Article Synopsis
- The concept of chronic primary pain (CPP) was introduced in 2019 to describe persistent pain without clear physical causes, often associated with emotional issues like depression.
- This study used EEG recordings to compare brain activity between healthy individuals, depressed patients, and those with CPP, identifying specific brain patterns related to each group.
- Results showed that both CPP and major depressive disorder share certain brain abnormalities, but CPP's changes in brain network dynamics differ from those seen in depression, suggesting unique underlying mechanisms and potential for future biomarker development.

Article Synopsis
- This study explores a brain-computer interface (BCI) that combines augmented reality (AR) with steady-state visual evoked potentials (SSVEP) to help users select real-world objects via visual focus.
- By enhancing real objects with visual stimuli, the system generates brain signals that SSVEP technology can interpret to identify what the user is looking at.
- The results show a 90.6% accuracy in recognizing SSVEP signals, proving it can assist people with mobility impairments in selecting objects in everyday scenarios.
Cervical spondylotic myelopathy (CSM) is the most severe type of cervical spondylosis. It is challenging to achieve early diagnosis with current clinical diagnostic tools. In this paper, we propose an end-to-end deep learning approach for early diagnosis of CSM.

This paper analyzes the characteristics of the pyroelectric detector based on its working principle. The input andoutput mathematical model of DIGA (Dispersive Infrared Gas Analyzer) system with pyroelectric detector was established according to the design principle of DIGA. We have manufactured a novel multi-gas DIGA on the basis of this model, then pointed out several problems that should be taken into account in the design.
