We investigated brain electric field signatures of subjective feelings after chewing regular gum or gum base without flavor. 19-channel eyes-closed EEG from 20 healthy males before and after 5 minutes of chewing the two gum types in random sequence was source modeled in the frequency domain using the FFT-Dipole-Approximation. 3-dimensional brain locations and strengths (Global Field Power, GFP) of the equivalent sources of five frequency bands were computed as changes from pre-chewing baseline…

Effect on electroencephalogram of chewing flavored gum
TLDR
The difference in the theta, alpha and beta bands in chewing gum with and without the added flavor suggested that the flavor as well as chewing could induce concentration with a harmonious high arousal state in brain function.
Gum chewing modulates heart rate variability under noise stress
TLDR
Findings suggest that gum chewing modulates HRV, but may not relieve acute stress caused by noise, as suggested by the State-Trait Anxiety Inventory and VAS.
Extraction of alpha activities from an EEG obtained during gum chewing
TLDR
This paper extracts alpha activities from an EEG recorded while a subject chews gum using independent component analysis (ICA) with simple preprocessing, and investigates whether or not the extracted signals satisfy the general characteristics of an alpha rhythm.
Effects of chewing gum on cognitive function, mood and physiology in stressed and non-stressed volunteers
TLDR
Chewing gum was associated with greater alertness and a more positive mood and reaction times were quicker in the gum condition, and this effect became bigger as the task became more difficult.
Nonlinear Dynamical Analysis of the Effect by Six Stimuli on Electroencephalogram
TLDR
The present study investigated the search by correlation dimension (D2) for the effect of six stimuli (sucrose, spearmint, gum-base chewing as a voluntary movement, and three combinations of these stimuli) on EEG findings, suggesting that D2 expressed the change in EEG as a brain response after each stimulus.
Chewing gum's effects on alertness, performance and stress
Chewing gum has previously been found to reduce chronic stress and enhance alertness, but effects on attention have been less reliable. The aim of this thesis was to investigate possible mechanisms…
Effects of chewing gum on mood, learning, memory and performance of an intelligence test
TLDR
Chewing gum improved the accuracy of performing the Alice Heim test which confirms the benefits of gum on test performance seen in an earlier study and suggests further research on the alerting effects of chewing gum and possible improved test performance in these situations.
Functional connectivity patterns of normal human swallowing: difference among various viscosity swallows in normal and chin-tuck head positions
Understanding consumer physiological and emotional responses to food products using electroencephalography (EEG)
Influence of attention and bolus volume on brain organization during swallowing
TLDR
Brain organization during no-distraction swallowing and swallowing with distraction was compared to show variations in bolus volume influenced the swallowing brain networks in the Delta, Theta, Alpha, Beta, and Gamma frequency bands, which could potentially lead to the development of better understanding of the nature of dysphagia.

Reflections on the topics: EEG frequency bands and regulation of vigilance.
TLDR
Existing concepts of vigilance for the awake stages are not contradictory to the following observations: the factor structure of EEG relative power spectrum variables shows a negative correlation of slow alpha-frequencies with those in the delta F- and beta 3F-band.
Effect of gum chewing on arousal in a self-reported psychologicall test
TLDR
Gum chewing affected all the three UMACL scales significantly, in comparison to the control data, and suggests that arousal effect from gum chewing is excellent and expedient.

Microstate segmentation of spontaneous multichannel EEG map series under diazepam and sulpiride.
TLDR
Spontaneous multichannel brain electric field map series of 20 seconds duration at 1, 15, 30, 45, and 60 minutes after the injection of a single dose of diazepam or sulpiride were segmented into microstates of quasi-constant landscape but varying durations, in agreement with expectations and with results using estimates of EEG model source locations in the frequency domain.

TLDR
The new gustometer is expected to be one of the standard objective methods of examining taste in clinical practice and will help men and animals to spend a tasteful life.
