Several wearable devices for physiological and activity monitoring are found on the market, but most of them only allow spot measurements. However, the continuous detection of physiological parameters without any constriction in time or space would be useful in several fields such as healthcare, fitness, and work. This can be achieved with the application of textile technologies for sensorized garments, where the sensors are completely embedded in the fabric. The complete integration of sensors in the fabric leads to several manufacturing techniques that allow dealing with both the technological challenges entailed by the physiological parameters under investigation, and the basic requirements of a garment such as perspiration, washability, and comfort. This review is intended to provide a detailed description of the textile technologies in terms of materials and manufacturing processes employed in the production of sensorized fabrics. The focus is pointed at the technical challenges and the advanced solutions introduced with respect to conventional sensors for recording different physiological parameters, and some interesting textile implementations for the acquisition of biopotentials, respiratory parameters, temperature and sweat are proposed. In the last section, an overview of the main garments on the market is depicted, also exploring some relevant projects under development.

The brain dynamics underlying working memory (WM) unroll via transient frequency-specific large-scale brain networks. This multidimensionality (time, space, and frequency) challenges traditional analyses. Through an unsupervised technique, the time delay embedded-hidden Markov model (TDE-HMM), we pursue a functional network analysis of magnetoencephalographic data from 38 healthy subjects acquired during an n-back task. Here we show that this model inferred task-specific networks with unique temporal (activation), spectral (phase-coupling connections), and spatial (power spectral density distribution) profiles. A theta frontoparietal network exerts attentional control and encodes the stimulus, an alpha temporo-occipital network rehearses the verbal information, and a broad-band frontoparietal network with a P300-like temporal profile leads the retrieval process and motor response. Therefore, this work provides a unified and integrated description of the multidimensional working memory dynamics that can be interpreted within the neuropsychological multi-component model of WM, improving the overall neurophysiological and neuropsychological comprehension of WM functioning.

In multiple sclerosis (MS), working memory (WM) impairment can occur soon after disease onset and significantly affects the patient’s quality of life. Functional imaging research in MS aims to investigate the neurophysiological underpinnings of WM impairment. In this context, we utilize a data-driven technique, the time delay embedded-hidden Markov model, to extract spectrally defined functional networks in magnetoencephalographic (MEG) data acquired during a WM visual-verbal n-back task. Here, we show that the activation of two networks is altered in relapsing remitting-MS patients. First, the activation of an early theta prefrontal network linked to stimulus encoding and attentional control significantly decreases in MS compared to HC. This diminished activation correlates with reduced accuracy and higher reaction time, suggesting that impaired attention control impacts task performance in MS patients. Secondly, a frontoparietal network characterized by beta coupling is activated between 300 and 600 ms post-stimulus, resembling the event-related P300, a cognitive marker extensively explored in EEG studies. The activation of this network is amplified in patients treated with benzodiazepine, in line with the well-known benzodiazepine-induced beta enhancement. Altogether, the TDE-HMM technique extracts task-relevant functional networks showing disease-specific and treatment-related alterations, revealing potential new markers to assess and track WM impairment in MS.

In this context, we utilized a data-driven technique, the time delay embedded- hidden Markov model (TDE-HMM), to extract spectrally defined functional networks in magnetoencephalographic (MEG) data acquired during a WM visual-verbal n-back task. We observed that two networks show an altered activation in RR-MS patients. First, the activation of an early theta prefrontal network linked to stimulus encoding and attentional control significantly decreased in RR-MS compared to HC. This diminished activation correlated with reduced accuracy in task performance in the MS group, suggesting an impaired encoding and learning process. Secondly, a frontoparietal network characterized by beta coupling is activated between 300 and 600 ms after stimulus onset; this resembles the characteristic event-related P300, a cognitive marker extensively explored in EEG studies. The activation of this network is amplified in patients treated with benzodiazepine, in line with the well-known benzodiazepine-induced beta enhancement. Altogether, the TDE-HMM technique extracted task-relevant functional networks showing disease-specific and treatment- related alterations, revealing potential new markers to assess and track WM impairment in MS. Highlights We decomposed the brain dynamics underlying a WM n-back task in data-driven, spectrally defined whole-brain networks in both healthy controls and people with relapsing-remitting-MS (pwMS). PwMS showed a significantly decreased activation of an early theta prefrontal network linked to stimulus encoding and attentional control. The weaker activation of this prefrontal theta network is correlated with worse task performance. A beta frontoparietal network with a P300-like temporal evolution was significantly modulated by the use of benzodiazepines. The model distinguished disease-induced and treatment-induced dynamic network alterations.

Today's life science endeavours are complex and interconnected, and they face diverse challenges, such as budgetary insecurity and the reproducibility crisis. As a result, core facilities have become vital in research institutes, transitioning from mere conveniences to essential components that ensure instrument access. Core facilities actively support and steer research with staff advising on experimental design and data interpretation. However, core facilities must, likewise, continually demonstrate their value, and there is no clear consensus on their optimal operational structure. Integration into larger, geographically distributed infrastructures represents a crucial opportunity for consolidation and differentiation, provided expertise and focus are clearly defined. Here, we outline concrete steps to emphasise specific application know‐how and increase visibility for imaging facilities to become future‐proof, improve matchmaking to attract the right users, and build international recognition across European infrastructures. By clearly delineating and differentiating expertise, core facilities can accelerate research and position themselves as integral components of large‐scale, durable infrastructures.

Information processing speed (IPS) is a core cognitive deficit in people with multiple sclerosis (PwMS). Previous efforts have associated IPS performance to frontal regions, but were constrained by limited temporal resolution. In this work, we employed a data-driven method, the time delay embedded-hidden Markov model (TDE-HMM), to identify task-specific states that are spectrally defined with distinct temporal and spatial profiles. We used magnetoencephalographic (MEG) data recorded while healthy controls and PwMS performed a cognitive task designed to capture IPS, the Symbol Digit Modalities Test (SDMT). The TDE-HMM identified five task-relevant states, supporting a tri-factor contribution to IPS: sensory speed (occipital visual detection and processing), cognitive speed (prefrontal executive and frontoparietal attention shift), and motor speed (sensorimotor). We observed reduced prefrontal and increased frontoparietal activation in PwMS, which correlated with offline SDMT performance. This work can drive future research for MS treatments targeting IPS improvements.
