The Cognitive Neuroscience of Insight and its Antecedents
Published in Steven Kornguth, Rebecca Steinberg, Michael D. Matthews, Neurocognitive and Physiological Factors During High-Tempo Operations, 2018
Comparing neural activity for insight and analytic solutions at the point of problem solution, fMRI revealed one statistically significant brain activation. There was greater brain activity for insight solutions in the anterior superior temporal gyrus of the right temporal lobe. This was confirmed by EEG, which found a burst of high-frequency (that is, gamma band) neural activity measured in electrodes over this location occurring at about the point in time at which the insight popped into awareness. Interestingly, the right anterior superior temporal gyrus is a brain area implicated in integrative conceptual processing, such as occurs in the processing of metaphors and jokes.
Trust me, if you can: a study on the factors that influence consumers’ purchase intention triggered by chatbots based on brain image evidence and self-reported assessments

Fourth, in comparison of no chatbots condition, we illustrate that chatbots increase both customers’ trust and purchase intention with the brain’s functionality from EEG, and help build positive customer relationship. Plassmann et al. (2015) as well as Venkatraman et al. (2015) asserted that activity in brain areas such as the dorsolateral prefrontal cortex and the superior temporal gyrus, as indicated by EEG and fMRI, constitute the strongest link to marketing. Recently, Hubert et al. (2018) expressed the effect of consumer behaviour on trustworthiness evaluations in online shopping by measuring the brain activity. These data provide evidence that consumer behaviour is closely linked to trust and activity in the dorsolateral prefrontal cortex. Consistent with prior studies, this research found that trust is associated with higher brain activation in the dorsolateral prefrontal cortex and the superior temporal gyrus.

Whole-brain activation results from the group (exercise intervention, control) by time (pre-test, post-test) ANOVA revealed that the following regions showed a significant interaction: left inferior frontal gyrus (IFG), right middle occipital gyrus (MOG), left hippocampus (HIP), left superior temporal gyrus (STG), left middle frontal gyrus (MFG), and right inferior parietal lobule (IPL). In all these regions, the exercise group showed a pattern of increasing activation over time, while the control group showed a stable pattern over time. All of these regions showed significant between-group differences at the post-test, and all group-by-time interactions remained significant when controlling for pre-test activation. For further details, see Table 2 and Figure 4.

The example of REA (right-ear advantage) given earlier illustrates how the physiology of the brain both enables and hinders the use of EEG. The phenomenon was reported in 1961, and its conclusions about hemispheric cross-talk were inferred from experimental results. By 2004 researchers could use EEG to measure the effect, not only at each ear but across the brain. Their method was to place a band of sensors between the ears, specifically P7, P3, PZ, P4 and P8 positions shown in Figure 7. The most extreme positions, P7 and P8, are located near the anterior superior temporal gyrus, which contains much of the primary auditory cortex [49]. After presenting stimuli, they searched for the timing of three particular waveforms as they passed between the auditory regions of each hemisphere [30]. These waveforms will be described in a following section.
