The middle insula has been associated with incidental self-processing of negative information elicited by individual's handwriting. However, emotional valence and arousal have been proved to work in an interactive way and located in middle insula. The present functional magnetic resonance imaging study used participant's handwritings as material to explore how incidental self-processing affected the interaction of valence and arousal and its neural basis.

- - The article discusses two main issues with MRI digital receivers: maintaining phase coherence between the transmitter and receiver, and improving the dynamic range of the receiver, with solutions including synchronous frequency switching and gain-switching techniques.
- - A digital receiver is designed using a variable gain amplifier, a high-speed analog-to-digital converter, and a digital receiver core, allowing for rapid frequency and gain adjustments through pre-stored waveforms.
- - Experimental results show significant improvements in phase coherence and dynamic range, suggesting that the digital receiver can enhance the quality of high-resolution multi-slice MRI images.
