“…fMRI records the blood-oxygen-level-dependent (BOLD) response that occurs during neuronal firing (see, Barth & Poser, 2011), offering an indirect measurement of neuronal activity to researchers investigating the neural underpinnings of cognitive functioning. Whilst the temporal resolution of fMRI is limited by the relatively slow BOLD response, its excellent spatial resolution enables researchers to produce images of spatially localised brain activation (Dalenberg, Hoogeveen, & Lorist, 2018). fMRI is not frequently used in developmental research with very young participants due to its expensive cost, the constraints of the scanner environment, and the high level of tolerance it requires from participants (Lloyd-Fox et al, 2010).…”

Highlights Advances in neuroimaging have facilitated the study of EF development early in life. Recent research continues to identify the pivotal role of the PFC in EF. Important changes occur in the prefrontal cortex across development. The importance of brain connectivity for EF is becoming increasingly clear. Functional brain specialisation for EF continues to develop into adolescence.

“…Utilizing Electroencephalogram (EEG) equipment, extremely comprehensive and precise attentionrelated data can be obtained [20]. Yet, stringent testing environments and high costs have limited the mass development of such equipment [21,22]. This has steered attention-related research towards machine vision-focused research proposals.…”

With the continuous development of technology, we have the opportunity to quantitatively study the internal behaviors of personnel, such as attention, in a suitable way, in order to better solve the "machine compensation" for workers and achieve the development of human-machine fusion. An exploration of how varying lighting conditions directly affect the eyes and, by extension, the individual's attention has been undertaken in this study. Image sensors capture the subject's eye movements during task participation, with the location of the eye's (pupil's) center aiding in gaze point recognition and facilitating the quantification of attention. A quantifiable model of "lighting-attention" has been developed through controlled lighting conditions and replicable experimental circumstances, thereby studying the alteration of attention under different lighting and road conditions. An initial calibration of a monocular vision gaze tracking system was achieved with two commercialgrade eye trackers and calibration software, achieving a precision level of 2 cm. Nine college students aged 20-21, divided into male and female control test groups, exhibited similar attention characteristics under various lighting conditions. Overall, a negative correlation between illumination intensity and attention is observed when exceeding a certain threshold. On average, female participants maintained higher attention levels for longer durations. The efficacy of the model proposed in this study has been proven through a series of tests, providing a quantifiable reference for the mechanisms influencing attention. So it can provide the basis for the study of the benefits of factory workers.

“…Studies have shown that neural activity and the hemodynamic response maintain a linear relationship (Arthurs and Boniface, 2003), and the NIR signal maintains a strong correlation with PET measures of changes in regional cerebral blood flow (rCBF) and the fMRI blood oxygen level-dependent (BOLD) signal (Toronov et al, 2003;Huppert et al, 2006), suggesting that fNIRS is an effective method for assessing cerebral activity. Compared with imaging devices, such as EEG, MEG, and fMRI (Coffey et al, 2016;Dalenberg et al, 2018), fNIRS has no ill-posed inverse problem in EEG and MEG (Helmholtz, 1853) and less interference from the external environment. Whereas the spatial resolution determines anatomical details, the temporal resolution determines the precision in which we can investigate successive neuronal events.…”

Cerebral Representation of Sound Localization Using Functional Near-Infrared Spectroscopy

Sound localization is an essential part of auditory processing. However, the cortical representation of identifying the direction of sound sources presented in the sound field using functional near-infrared spectroscopy (fNIRS) is currently unknown. Therefore, in this study, we used fNIRS to investigate the cerebral representation of different sound sources. Twenty-five normal-hearing subjects (aged 26 ± 2.7, male 11, female 14) were included and actively took part in a block design task. The test setup for sound localization was composed of a seven-speaker array spanning a horizontal arc of 180° in front of the participants. Pink noise bursts with two intensity levels (48 dB/58 dB) were randomly applied via five loudspeakers (–90°/–30°/–0°/+30°/+90°). Sound localization task performances were collected, and simultaneous signals from auditory processing cortical fields were recorded for analysis by using a support vector machine (SVM). The results showed a classification accuracy of 73.60, 75.60, and 77.40% on average at –90°/0°, 0°/+90°, and –90°/+90° with high intensity, and 70.60, 73.6, and 78.6% with low intensity. The increase of oxyhemoglobin was observed in the bilateral non-primary auditory cortex (AC) and dorsolateral prefrontal cortex (dlPFC). In conclusion, the oxyhemoglobin (oxy-Hb) response showed different neural activity patterns between the lateral and front sources in the AC and dlPFC. Our results may serve as a basic contribution for further research on the use of fNIRS in spatial auditory studies.
