Abstract

Electrocortical effects of long duration exercise on cognitive function were investigated by analyzing P300 amplitude and latency changes during a 3-h cycling exercise. P300 components were measured in 12 well-trained cyclists and blood glucose, cortisol, insulin, glycerol, and free fatty acids (FFAs) epinephrine and norepinephrine were analyzed. Results indicated that P300 components were affected by exercise with a temporary increase in amplitude between the 1st and the 2nd hour and an increase in latency after 2 h of exercise concomitant with some hormonal changes, including an increase in cortisol and epinephrine and a decrease in blood glucose. These findings suggest a combined effect of arousal and central fatigue on electrocortical indices of cognitive function during acute physical exercise.

Medium chain triglycerides with a C8:C10 ratio of 30:70 enhances cognitive performance and mitigates the cognitive decline associated with prolonged exercise in young and healthy adults
2023, Physiology and Behavior
Prolonged exercise has been linked to a decline in cognitive function due to a variety of factors, such as a drop in oxygen in the prefrontal cortex and an increase in stress hormones and neurotransmitters. Medium chain triglycerides (MCTs) may possibly offset this decline as they provide energy for the brain via both direct and indirect pathways, alongside promoting chronic physiological adaptations within the brain.
Participants were divided into two groups; MCT (n = 9) and Placebo (n = 10). The MCT gels contained 6 g of MCT with a C₈:C₁₀ ratio of 30:70, whereas the placebo gels contained carbohydrates of similar calorific value to the MCT gels. Participants visited the laboratory on three occasions (familiarisation/fitness test, pre-supplementation, post-supplementation), during which they performed a battery of cognitive tasks assessing domains such as processing speed, working memory, selective attention, decision making and coordination, before and after a prolonged bout of exercise (60 mins at 90% gas exchange threshold (GET). A 2-week supplementation period between visits 2 and 3 involved the ingestion of 2 gels per day.
Exercise resulted in detriments in most cognitive tasks pre-supplementation for both groups, and post-supplementation for the Placebo group (main effect ps< 0.05). Post-supplementation, the effect of exercise was mediated in the MCT group for all cognitive tasks (main effect ps< 0.05), except for the Digit and Spatial Span Backwards test phases (main effect ps> 0.05). Furthermore, MCT supplementation enhanced before-exercise cognitive performance and in some measures, such as working memory, this was maintained after-exercise (interaction effect ps> 0.05).
Chronic MCT supplementation enhanced before-exercise cognitive performance and offset the cognitive decline caused by a prolonged bout of exercise. In some cases, improvements in before-exercise cognitive performance were maintained after-exercise.
The acute exercise-cognition interaction: From the catecholamines hypothesis to an interoception model
2021, International Journal of Psychophysiology
An interoception model for the acute exercise-cognition interaction is presented. During exercise following the norepinephrine threshold, interoceptive feedback induces increased tonic release of extracellular catecholamines, facilitating phasic release hence better cognitive performance of executive functions. When exercise intensity increases to maximum, the nature of task-induced norepinephrine release from the locus coeruleus is dependent on interaction between motivation, perceived effort costs and perceived availability of resources. This is controlled by interaction between the rostral and dorsolateral prefrontal cortices, orbitofrontal cortex, anterior cingulate cortex and anterior insula cortex. If perceived available resources are sufficient to meet predicted effort costs and reward value is high, tonic release from the locus coeruleus is attenuated thus facilitating phasic release, therefore cognition is not inhibited. However, if perceived available resources are insufficient to meet predicted effort costs or reward value is low, tonic release from the locus coeruleus is induced, attenuating phasic release. As a result, cognition is inhibited, although long-term memory and tasks that require switching to new stimuli-response couplings are probably facilitated.
HVD-LSTM based recognition of epileptic seizures and normal human activity
2021, Computers in Biology and Medicine
In this paper, we detect the occurrence of epileptic seizures in patients as well as activities namely stand, walk, and exercise in healthy persons, leveraging EEG (electroencephalogram) signals. Using Hilbert vibration decomposition (HVD) on non-linear and non-stationary EEG signal, we obtain multiple monocomponents varying in terms of amplitude and frequency. After decomposition, we extract features from the monocomponent matrix of the EEG signals. The instantaneous amplitude of the HVD monocomponents varies because of the motion artifacts present in EEG signals. Hence, the acquired statistical features from the instantaneous amplitude help in identifying the epileptic seizures and the normal human activities. The features selected by correlation-based Q-score are classified using an LSTM (Long Short Term Memory) based deep learning model in which the feature-based weight update maximizes the classification accuracy. For epilepsy diagnosis using the Bonn dataset and activity recognition leveraging our Sensor Networks Research Lab (SNRL) data, we achieve testing classification accuracies of 96.00% and 83.30% respectively through our proposed method.
A single bout of vigorous-intensity aerobic exercise affects reactive, but not proactive cognitive brain functions
2020, International Journal of Psychophysiology

ERP-fMRI co-registration studies have localized the neural sources of the P3 in multiple brain areas such as frontal, temporal, parietal, and insular cortices (e.g., Bledowski, 2004; Hong et al., 2017, Ragazzoni et al., 2019). There is robust evidence in favor of the acute modulatory effect of MIAE on the P3 (e.g. Chu et al., 2017Chu et al., 2015Chang et al., 2015b;Chang, 2016 Kamijo et al., 2004, Kamijo et al., 2009 Drollette et al., 2014Kamijo et al., 2009 Kamijo et al., 2004 Kao et al., 2017; Hillman et al., 2003, 2009; Olson et al., 2016; Pontifex et al., 2013 Pontifex et al., 2015 Grego et al., 2004; Yagi et al., 1999), with the exception of one MIAE study that reported no P3 effects (Stroth et al., 2009). However, it is only recently that researchers started to explore the effect of VIAE on P3.
The literature on aerobic exercise and neurocognition reports acute post-exercise enhancement of neural activity linked to motor preparation in the premotor area and inhibitory control in the frontoparietal areas. However, the acute effect of vigorous-intensity aerobic exercise (VIAE) on the prefrontal, the insular, and the occipito-parietal activities linked to proactive control, early perceptual, and attentional processing is indeterminate. Thus, the present study investigated the acute effect of VIAE on the neurobehavioral correlates of these proactive and reactive neurocognitive functions. Young, healthy subjects participated in two separate experimental sessions: 30 min of VIAE and 30 min of internet browsing. Before and immediately after the two sessions, we recorded high-resolution electroencephalograms while performing a visuomotor discriminative response task. For testing the effect of VIAE on cognitive processing, we analyzed the behavioral performance and event-related potentials (ERPs). The analysis of behavioral data did not reveal any VIAE effect on task performance. The analysis of ERPs showed no significant VIAE effect on the proactive functions in the premotor and the prefrontal areas, but significant effects on the reactive functions related to selective attention in parietal areas (indexed by the N1 amplitude) and perceptual awareness in the anterior insula (indexed by the pN1 latency). We concluded that a single bout of VIAE does not affect the proactive functions in the premotor and the prefrontal areas, but modulates the early reactive neural mechanisms underlying perceptual awareness of stimuli in the insular cortex and selective attention in the parieto-occipital areas.
