Amnestic mild cognitive impairment (aMCI) is the prodromal period of more serious neurodegenerative diseases (e.g., Alzheimer's disease), characterized by declines in memory and thinking abilities. Auxiliary assessment early diagnosis aMCI are crucial preventing continued deterioration abilities; nevertheless, this task poses a formidable challenge due to inconspicuous nature symptoms. Functional near-infrared spectroscopy (fNIRS) non-invasive, low-cost, user-friendly neuroimaging technique, which capable detecting subtle changes brain activity among different subjects. Moreover, multimodal fusion can assess cognition status from perspectives enhance auxiliary accuracy significantly. This paper proposes an fNIRS representation fNIRS-scales method for aMCI. Specifically, we convert one-dimensional time-series signals into two-dimensional images with Gramian Angular Field achieve end-to-end convolutional neural network. Then, integrate extracted features scales at decision-making level improve aMCI, employing data balance strategy prevent biased prediction. What more, based on features, also propose data-driven scales-screening help physician higher efficiency. We conducted experiments 86 subjects (including 53 patients 33 normal controls) recruited Foshan First People's Hospital. The reaches 88.02% 93.90% further fusion, respectively. With scales-screening, delete 50% scales, reducing test time but only losing 2.54% accuracy.

Research investigating the neural processes related to music perception and production constitutes a well-established field within cognitive neurosciences. While most neuroimaging tools have limitations in studying complexity of musical experiences, functional Near-Infrared Spectroscopy (fNIRS) represents promising, relatively new tool for both laboratory ecological settings, which is also suitable typical pathological populations across development. Here we systematically review fNIRS studies on cognition, highlighting prospects potentialities. We include an overview basic theory, together with brief comparison characteristics other tools. Fifty-nine meeting inclusion criteria (i.e., using as primary stimulus) are presented five thematic sections. Critical discussion methodology leads us propose guidelines good practices aiming robust signal analyses reproducibility. A continuously updated world map proposed, including information from criteria. It provides organized, accessible, updatable reference database, could serve catalyst future collaborations community. In conclusion, shows potential music, particularly contexts special populations, aligning current research priorities cognition.

Electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) can objectively reflect a person’s emotional state have been widely studied in emotion recognition. However, the effective feature fusion discriminative learning from EEG–fNIRS data is challenging. In order to improve accuracy of recognition, graph convolution capsule attention network model (GCN-CA-CapsNet) proposed. Firstly, signals are collected 50 subjects induced by video clips. And then, features EEG fNIRS extracted; fused generate higher-quality primary capsules with Pearson correlation adjacency matrix. Finally, module introduced assign different weights capsules, selected better classification dynamic routing mechanism. We validate efficacy proposed method on our dataset an ablation study. Extensive experiments demonstrate that GCN-CA-CapsNet achieves more satisfactory performance against state-of-the-art methods, average increase 3–11%.

Near-infrared spectroscopy (NIRS) is a non-invasive monitoring technique that utilizes light transmission and absorption to continuously evaluate regional tissue oxygen saturation, delivery, metabolism. Widely adopted in modern clinical practice, NIRS particularly effective assessing cerebral oxygenation, enabling the early detection of impaired perfusion. Grounded Beer–Lambert law, relies on characteristics oxyhemoglobin deoxyhemoglobin as primary chromophores biological tissues. This chapter provides comprehensive overview technology its applications biomedical fields. It begins by discussing fundamental assumptions, advantages, limitations NIRS, along with typical structure system. Following this, principles properties are explored depth.

Disorders of consciousness (DoC) resulting from severe brain injury present substantial challenges in rehabilitation due to disruptions network connectivity, particularly within the frontal-parietal critical for awareness. Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a promising non-invasive intervention; however, precise mechanisms through which it influences cortical function DoC patients remain unclear. This study describes effects taVNS on fronto-parietal connectivity and arousal 77-year-old female patient with unresponsive wakefulness syndrome (UWS). The received bilateral 1 h daily over 3 months, functional (FC) frontoparietal assessed using near-infrared spectroscopy (fNIRS) behavioral responsiveness evaluated Coma Recovery Scale-Revised (CRS-R). After intervention, mean FC was enhanced 0.06 (SD = 0.31) 0.33 0.28) network. were subdivided into 12 regions interest (ROIs) determined that between left dorsolateral prefrontal cortex (DLPFC) ROIs ± 0.41 before intervention 0.55 0.24 after intervention.

Additionally, associated auditory sensory processing showed increased engagement, supporting positive impact responsiveness. suggests its value adjunctive therapy patients. Further studies are necessary confirm these wider population refine strategy clinical application taVNS.
