“…The latency of P300 is often used to reflect short-term memory, selective attention, and reaction speed, the ability to process events, and cognitive processing[ 27 ], and the amplitude of P300 reflects the resources invested in the brain when it senses incoming stimulus information, namely, the active control of attention and the ability of information processing. The decrease of P300 amplitude and the prolongation of latency indicate the decline of cognitive ability, and P300 latency is more sensitive to the occurrence of early CRCI than P300 amplitude response, so P300 amplitude and latency can be used as biological markers of cognitive physiological mechanism[ 28 , 29 ]. The present study was completed by auditory stimulation under the oddball paradigm, and the latency of P300 was significantly shortened and the amplitude of P300 was significantly increased in CRC patients receiving 3 mo of CBT combined with exercise intervention, and the difference became more significant with the duration of the intervention.…”

BACKGROUND Cancer-related fatigue (CRF) is the most common concomitant symptom in the treatment of colorectal cancer (CRC). Such patients often present with subjective fatigue state accompanied by cognitive dysfunction, which seriously affects the quality of life of patients. AIM To explore the effects of cognitive behavior therapy (CBT) combined with Baduanjin exercise on CRF, cognitive impairment, and quality of life in patients with CRC after chemotherapy, and to provide a theoretical basis and practical reference for rehabilitation of CRC after chemotherapy. METHODS Fifty-five patients with CRC after radical resection and chemotherapy were randomly divided into either an experimental or a control group. The experimental group received the intervention of CBT combined with exercise intervention for 6 mo, and indicators were observed and measured at baseline, 3 mo, and 6 mo to evaluate the intervention effect. RESULTS Compared with the baseline values, in the experimental group 3 mo after intervention, cognitive function, quality of life score, and P300 amplitude and latency changes were significantly better ( P < 0.01). Compared with the control group, at 3 mo, the experimental group had significant differences in CRF, P300 amplitude, and quality of life score ( P < 0.05), as well as significant differences in P300 latency and cognitive function ( P < 0.01). Compared with the control group, at 6 mo, CRF, P300 amplitude, P300 latency, cognitive function and quality of life score were further improved in the experimental group, with significant differences ( P < 0.01). The total score of CRF and the scores of each dimension were negatively correlated with quality of life ( P < 0.05), while the total score of cognitive impairment and the scores of each dimension were positively correlated with quality of life ( P < 0.05). CONCLUSION CBT combined with body-building Baduanjin exercise can improve CRF and cognitive impairment in CRC patients after chemotherapy, and improve their quality of life.

“…In the second auditory ERP, there was a signi cant correlation between C CL and MMSE place, between C CL and MMSE recall, between Cz and MMSE total, between Cz and MMSE recall, between C IL and MMSE place, between C IL and MMSE recall, and between C IL and MoCA abstraction. (Table 13,14,15,16,17,18,19,20) In the rst visual ERP (latency), there was a signi cant correlation between Cz and MMSE (sum) and between C IL and MMSE (sum), attention & calculation, language, MoCA (sum), visuospatial and executive (MoCA), and attention (MoCA). In the second visual ERP, there was a signi cant correlation between C IL and visuospatial and executive (MoCA) and between P IL and attention (MoCA).…”

The aim of this study was assess the test-retest reliability of the ERP and resting EEG test in subacute stroke patients. Additionally, we compared the validity of the EEG, ERP test to MMSE (Mini-Mental State Exam) and MoCA (Montreal Cognitive Assessment) to use it as an objective tool to evaluate cognitive function. We recruited 20 patients with subacute ischemic stroke who were 19 years of age or older and had an MMSE score of 20 or higher. All participants were tested K-MMSE (Korean Mini Psychostatistics Test) and K-MoCA (Korea-Montreal Cognitive Assessment). The resting-state EEG and P300 wave using an auditory and visual oddball paradigm were measured at baseline and once again in 24 hours. We calculated the brain symmetry index (BSI) and directional BSI (BSIdir) over different frequency bands and delta/alpha ratio (DAR). The intra-rater reliability and validity of the P300 latency, amplitude, BSI, BSIdir and DAR were measured by intra-class correlation (ICC) analysis and by Pearson`s correlation coefficient analysis, respectively. P300 latency showed excellent ICC level (auditory P contralesional, ICC = 0.918, visual P contralesional, ICC = 0.972, visual Pz, ICC = 0.945). In the visual ERP (latency), there was a significant correlation between Cz, C ipsilesional and Mini-Mental State Exam (MMSE) and C ipsilesional and Montreal Cognitive Assessment (MoCA). The P contralesional and Pz latency of visual ERP showed significant reliability, and the Cz and C ipsilesional of visual latency showed effectiveness in reflecting the cognitive function. Thus, these montages could be used as a basis for future studies.

Brain-computer interfaces are sophisticated signal processing systems, which directly operate on neuronal signals to identify specific human intents. These systems can be applied to overcome certain disabilities or to enhance the natural capabilities of human beings. The visual P300 mind-speller is a prominent one among them, which has opened up tremendous possibilities in movement and communication applications. Today, there exist many state-of-the-art visual P300 mind-speller implementations in the literature as a result of numerous researches in this domain over the past 2 decades. Each of these systems can be evaluated in terms of performance metrics like classification accuracy, information transfer rate, and processing time. Various classification techniques associated with these systems, which include but are not limited to discriminant analysis, support vector machine, neural network, distance-based and ensemble of classifiers, have major roles in determining the overall system performances. The significance of a proper review on the recent developments in visual P300 mind-spellers with proper emphasis on their classification algorithms is the key insight for this work. This article is organized with a brief introduction to P300, concepts of visual P300 mind-spellers, the survey of literature with special focus on classification algorithms, followed by the discussion of various challenges and future directions.
