The formulation has been designed to support the body's natural neurotransmitters, and to enhance peak mental alertness and mental energy. ... No caffeine or other stimulants are used in BRAIN FORMULA and it may be taken daily or just for those times when peak mental alertness and mental energy are desired.

- Assessment of Sleepiness and Alertness .
- According to our hypothesis alertness and its antonym sleepiness has many facets so that it will not be possible to assess this complexe condition by using only one measurement technique. We suggest to apply a larger number of different subjective and objective measurement techniques in order to describe alertness/sleepiness adequately. ...

- Body: Those mysterious, unnamed `scientists' have created an equation for determining your level of alertness (or level of tiredness, same thing). ... Then, if you're like me, you can schedule math problems, academic reading, and writing at the times of greatest alertness, and other stuff when you're sluggish. ...
4. Changes in alertness and the EEG spectrum
- www.sccn.ucsd.edu
- CHANGES IN ALERTNESS ARE A PRINCIPAL COMPONENT OF VARIANCE IN THE EEG SPECTRUM .
- These EEG changes apparently arise from simultaneous changes in brain mechanisms controlling central arousal and alertness and in the levels of coherent neural activity at several characteristic neural oscillation frequencies. The unidimensional relationship between changes in performance and the EEG spectrum during drowsiness may make possible practical methods of EEG-based real-time alertness estimation. ...
- The one-dimensional relationship between detection performance and the EEG spectrum confirms quantitatively the intuitive assumption that minute-scale changes in behavioral alertness during drowsiness are predominantly linked to changes in global brain dynamics along a single dimension of psychophysiological arousal. Key Words: EEG, electroencephalogram, alertness, vigilance, auditory detection, principal component analysis (PCA), spectrum Disclaimer This Report was supported by a grant ONR. ...
- Here, arousal refers primarily to changes in behavior associated with transitions from slow-wave sleep to waking, and alertness, to the waking end of this continuum. ... Here we report, first, that a similar relation exists between changes in the EEG spectrum and auditory detection performance during eyes-open, dual-task performance, and second, that spectral changes linearly related to alertness form a single principal component of overall variance in the normalized EEG log spectrum. ...
- Yet, both experiments yield very similar frequency-weighted components relating changes in alertness and the EEG spectrum during drowsiness. ... Such factors may make nonlinear fitting algorithms or artificial neural networks more efficient than linear regression in estimating changes in alertness from EEG records 8 . ... It should be interesting to test whether similar results are obtained when links between EEG changes and behavioral alertness are examined using more complex or demanding tasks. ...
- Elsewhere, we have shown that these EEG spectral correlates of loss of alertness can be used to monitor the timecourse of alertness in near real time, for scientific or applied purposes 8 . ...
5. Alertness Monitoring
- www.cnl.salk.edu
- Alertness Monitoring.
- Many studies of vigilance research during the past few decades have shown that, for most or all operators engaged in attention-intensive and monotonous tasks, retaining a constant level of alertness is rare if not impossible. Alertness deficits may lead to severe consequences in occupations ranging from air traffic control to monitoring of nuclear power plants. Changes in the electroencephalographic (EEG) power spectrum accompany these fluctuations in the level of alertness, as assessed by measuring simultaneous changes in EEG and performance on an auditory monitoring task. By combining power spectrum estimation, principal component analysis and artificial neural networks, we now can accurately estimate, continuously and near real-time, an operator's global level of alertness using EEG measures from as few as two central scalp sites. ...
- The figure below shows the results of alertness estimation.
- When the operator loses alertness, and begins to become drowsy, he begins to miss targets.
- An individualized model of alertness changes in the EEG was derived from data recorded in a previous session for this subject. ...
- Earlier experiments at NHRC showed that the EEG-based error rate estimates can be used to deliver feedback to operators that can help them to manage their own alertness and improve their overall monitoring performance. ...

6. Flight Controller Alertness and Performance
- human-factors.arc.nasa.gov
- FLIGHT CONTROLLER ALERTNESS AND PERFORMANCE.
- Decreased alertness and performance associated with fatigue, sleep loss, and circadian disruption are issues faced by a diverse range of shiftwork operations. ... The initial results clearly support further data collection during other STS missions to document baseline levels of alertness and performance during MOD shiftwork operations. ... Implementation and evaluation of the countermeasure strategies to maximize alertness and performance is planned. ... Space Station operations continues, alertness and performance issues related to sleep and circadian disruption will remain highly relevant in the MOD environment.
- MOD Shiftwork Evaluation of Performance and Mood Packet: The MOD Shiftwork Evaluation of Performance and Mood Packet included measures of performance and alertness selected according to three criteria: (1) their sensitivity to sleep loss, circadian variation and fatigue from shiftwork; (2) the extent to which they reflected fundamental elements in the cognitive work demands of Flight Controllers; and (3) their brevity and unobtrusiveness for use as probes during flight operations. ...
- Due to scheduling constraints, for most volunteers the process of baseline performance and alertness evaluations was also done in the post-flight time frame and paralleled the methodology used during the flight.
- Performance and alertness data were analyzed descriptively. ...
- Subjective measures of sleepiness, alertness, and fatigue showed similar trends on day 1 of mission, regardless of the type of psychometric used. ...
- When differences did emerge among shifts they tended to cluster in the domain of sleepiness/fatigue/alertness, on both subjective and objective measures, and they appeared to be associated, as expected, with night shift operations. ... We conclude that Flight Controllers working night shift either acutely or chronically may be at increased risk of lowered alertness and reduced performance capacity, especially during the first few days of mission. ... The Phase I Operational Test demonstrated clearly that it is possible to safely and efficiently acquire objective data through periodic probes of performance and alertness in Flight Controllers, during shifts and across mission days, without interfering with mission goals or operations. ...
- Intervention recommendations might include shiftwork education and training, the development of preventive strategies prior to and during mission, and the development of operational countermeasures to maintain alertness and performance during missions (Rosekind et al. ...
