Article Synopsis
- This study focuses on improving emotion recognition using EEG signals by creating a method that reduces the number of EEG channels while preserving signal quality.
- It employs a stacked autoencoder network to efficiently extract features for classifying emotions based on valence and arousal.
- The results show a successful accuracy rate of approximately 75.7% for valence and 74.4% for arousal, while also demonstrating a reduction in signal channels from 32 to 12, aiding the development of compact EEG devices.
People with Parkinson's disease often exhibit improvements in motor tasks when exposed to external sensory cues. While the effects of different types of sensory cues on motor functions in Parkinson's disease have been widely studied, the underlying neural mechanism of these effects and the potential of sensory cues to alter the motor cortical activity patterns and functional connectivity of cortical motor areas are still unclear. This study aims to compare changes in oxygenated haemoglobin, deoxygenated haemoglobin and correlations among different cortical regions of interest during wrist movement under different external stimulus conditions between people with Parkinson's disease and controls.

This may lead to falling down, syncope, and in general reducing the quality of daily activities, especially in the elderly and anyone suffering from nervous system disorders such as Parkinson's or orthostatic hypotension (OH). Among different modalities to study brain function, functional near-infrared spectroscopy (fNIRS) is a neuroimaging method that optically measures the hemodynamic response in brain tissue.

We explored the extent of the reduction and whether or not it reaches the general population level in a large cohort of patients with obesity. This study aimed to compare all-cause mortality between patients with obesity who undergo bariatric surgery and those who do not, with the general Iranian population during the same period.

Methods: Adult Iranian population received RCP or BBIBP in a randomized, double blind and an additional non-randomized open labeled trial arms. Eligible participants signed a written informed consent and received two intramuscular injections three weeks apart.
