“…One early investigation by Krause et al (1983) focused on isometric exertion involving arm muscles, whereby peak alpha frequency was significantly higher when the participants performed the task with closed eyes. This was an interesting finding at that time, which could not be explained by the authors.…”

Recent years have seen increased interest in neuroergonomics, which investigates the brain activities of people engaged in diverse physical and cognitive activities at work and in everyday life. The present work extends upon prior assessments of the state of this art. However, here we narrow our focus specifically to studies that use electroencephalography (EEG) to measure brain activity, correlates, and effects during physical activity. The review uses systematically selected, openly published works derived from a guided search through peer-reviewed journals and conference proceedings. Identified studies were then categorized by the type of physical activity and evaluated considering methodological and chronological aspects via statistical and content-based analyses. From the identified works ( n = 110), a specific number ( n = 38) focused on less mobile muscular activities, while an additional group ( n = 22) featured both physical and cognitive tasks. The remainder ( n = 50) investigated various physical exercises and sporting activities and thus were here identified as a miscellaneous grouping. Most of the physical activities were isometric exertions, moving parts of upper and lower limbs, or walking and cycling. These primary categories were sub-categorized based on movement patterns, the use of the event-related potentials (ERP) technique, the use of recording methods along with EEG and considering mental effects. Further information on subjects' gender, EEG recording devices, data processing, and artifact correction methods and citations was extracted. Due to the heterogeneous nature of the findings from various studies, statistical analyses were not performed. These were thus included in a descriptive fashion. Finally, contemporary research gaps were pointed out, and future research prospects to address those gaps were discussed.

“…Spectral analysis of raw EEG traces is important, because different frequency bands have been linked to different aspects of brain function. For example, slow-wave frequencies such as those encompassing the delta band, play a role in the regulation of and/or reflect the status of homeostasis maintenance, while higher frequency waves are associated with higher brain functions as well as muscular coordination and feedback (25–30). In primates, including humans and macaques, sleep can be characterized into non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM); NREM sleep is correlated with slow wave EEG activity, as encompassed by the delta wave band (31–33).…”

49Alphaviruses such as Venezuelan equine encephalitis virus (VEEV) and Eastern equine encephalitis 50 virus (EEEV) are arboviruses that can cause severe zoonotic disease in humans. Both VEEV and EEEV are 51 highly infectious when aerosolized and can be used as biological weapons. Vaccines and therapeutics are 52 urgently needed, but efficacy determination requires animal models. The cynomolgus macaque (Macaca 53 fascicularis) provides a relevant model of human disease, but questions remain whether vaccines or therapeutics 54 can mitigate CNS infection or disease in this model. 55 The documentation of alphavirus encephalitis in animals relies on traditional physiological biomarkers 56 and behavioral/neurological observations by veterinary staff; quantitative measurements such as 57 electroencephalography (EEG) and intracranial pressure (ICP) can recapitulate underlying encephalitic 58 processes. We detail a telemetry implantation method suitable for continuous monitoring of both EEG and ICP 59 in awake macaques, as well as methods for collection and analysis of such data. We sought to evaluate whether 60 changes in EEG/ICP suggestive of CNS penetration by virus would be seen after aerosol exposure of naïve 61 macaques to VEEV IC INH9813 or EEEV V105 strains compared to mock-infection in a cohort of twelve adult 62 cynomolgus macaques. 63 Data collection ran continuously from at least four days preceding aerosol exposure and up to 50 days 64 thereafter. EEG signals were processed into frequency spectrum bands (delta: [0.4 -4Hz); theta: [4 -8Hz); 65 alpha: [8-12Hz); beta: [12-30] Hz) and assessed for viral encephalitis-associated changes against robust 66 background circadian variation while ICP data was assessed for signal fidelity, circadian variability, and for 67 meaningful differences during encephalitis. Results indicated differences in delta, alpha, and beta band 68 magnitude in infected macaques, disrupted circadian rhythm, and proportional increases in ICP in response to 69 alphavirus infection. This novel enhancement of the cynomolgus macaque model offers utility for timely 70 determination of onset, severity, and resolution of encephalitic disease and for the evaluation of vaccine and 71 therapeutic candidates. 72 3 73 Introduction 74 Alphaviruses, a genus of the family Togaviridae, are a group of linear, non-segmented positive-sense single-75 stranded RNA arboviruses found in many regions of the world. "New World" alphaviruses can invade the central 76 nervous system (CNS) and cause severe encephalitis which can be diagnosed by fever, brain swelling, and 77 neurological symptoms such as seizures and a diffuse slowing of brain activity across the physiologically relevant 78 electroencephalography (EEG) frequency spectra (1, 2). While Venezuelan equine encephalitis virus (VEEV) is 79 only rarely lethal in humans, North American strains of Eastern equine encephalitis virus (EEEV) have a high 80 mortality rate in confirmed cases (estimates range from 30-70% between outbreaks) and a high percentage of 81 sur...
