“…Further, trends databases, including Google Trends, can be explored in connection with the topic of pre-mortem psychedelic tripping to assess the digital epidemiology and geography of people interested in the subject. It is also essential to inspect the concepts of cerebral dominance (lateralisation of brain functions), manifested as patterns of handedness in the population, that may interfere with the decision-making process (Al-Hadithi, Al-Imam, Irfan, Khalaf, & Al-Khafaji, 2016;Al-Hadithi & Al-Imam, 2017;Al-Imam, 2017e;Al-Imam, 2018;Al-Imam, Ali, & Saad, 2018). Additionally, online and offline surveys and interviews should be deployed to reduce the reliance on web snapshot technique that is prone to errors and biases.…”

Background: The surface web is a rich source of extensive data on populations of users and misusers of psychoactive substances including substances known as hallucinogens and entheogens. The internet and its social media websites can serve as a database upon which several hypotheses are applicable via thematic analytic and psychoanalytic studies. Materials and Methods: This study will deploy the use of an internet snapshot by inspecting, via thematic analysis, the comments of a population of psychedelic (ab)users existing on the Facebook social platform. The snapshot will dare to answer an existing question in connection with the concept of using psychedelics and entheogens during the moments preceding death. Several demographics will be explored including ethnic-national and socio-cultural parameters to test several hypotheses about the tendencies for having an ultimate pre-mortem psychedelic trip towards the ambiguous afterlife. Results: Most of the psychedelic users recommended the use of DMT for the final journey. Others have suggested tripping on LSD, Psilocybin and Psilocybin mushrooms, NBOMe compounds, and even opiates. Based on inferential models, it seems that tendencies for the pre-mortem trip are not affected by the status of social relations, ethnicity, nationality, age, or sex. However, it appears to be based on the individualistic build-up. Religious affiliations and other cultural norms represent potential confounding variables. Hence, these must be explored in subsequent studies. Conclusion: In the future and to keep in pace with the logarithmic growth and arachnoid expansion of the web and its appendages, ambitious studies has to deploy the use of concepts of automation in data science via the exploitation of principles of machine learning and deep thinking. The aim is to achieve statistical inference in real-time and accurate predictions when it comes to running analytics on big data. If successfully applied, the benefits for the public health should be monumental.

“…The correlation between handedness and complex visual analytic skills has been studied before, emphasising on the significance of handedness, cerebral dominance patterns, and visual skills (11)(12)(13)(14)(15). Gauthier, Kanwisher, McCarthy, Casper, and colleagues investigated specific areas of the brain in relation to face recognition abilities.…”

“…Moreover, Al-Imam et al suggested further studies on a specific population, including users of novel psychoactive substances (NPS). The analyses can be further extended to include visual analytic skills and face recognition abilities (11,12).…”

Background: The ability of humans to recognise faces of countless individuals is unique and has an evolutionary basis. The cortical surface, responsible for this task, is significantly large in humans. The aim of this study was to analyze the face recognition abilities of a selected population of Iraqi students and to determine the correlation of these abilities with gender, handedness, and ethnicity.

“…Researchers should attempt to study osteology as well as radiology-based samples and compare the results from each to contrast premortem and postmortem specimens. They should also study and compare different ethnicities, age groups, patterns of lateralization of brain functions for the potential modifier effect on the stomatognathic system [51,52]. Research can involve individuals with pathologies and conditions of interest, for example, those with alveolar osteitis, pterygoid implants, dental prostheses, and ailments that can affect bone density and microstructure.…”

Background:The base of the skull, particularly the pterygomaxillary region, has a sophisticated topography, the morphometry of which interests pathologists, maxillofacial and plastic surgeons. The aim of the study was to conduct pterygomaxillary morphometrics and test relevant hypotheses on sexual and laterality-based dimorphism, and causality relationships. Materials and methods:We handled 60 dry skulls of adult Asian males (36.7%) and females (63.3%). We calculated the prime distance D [prime] for the imaginary line from the maxillary tuberosity to the midpoint of the pterygoid process between the upper and the lower part of the pterygomaxillary fissure, as well as the parasagittal D [x-y inclin.] and coronal inclination of D [x-z inclin.] of the same line. We also took other morphometrics concerning the reference point, the maxillary tuberosity.Results: Significant sexual as well as laterality-based dimorphism and bivariate correlations existed. The univariate models could not detect any significant effect of the predictors. On the contrary, summative multivariate tests in congruence with neural networks, detected a significant effect of laterality on D [x-y inclin.] (p-value = 0.066, partial eta squared = 0.030), and the interaction of laterality and sex on D [x-z inclin.] (pvalue = 0.050, partial eta squared = 0.034). K-means clustering generated three clusters highlighting the significant classifier effect of D [prime] and its three-dimensional inclination.Conclusions: Although the predictors in our analytics had weak-to-moderate effect size underlining the existence of unknown explanatory factors, it provided novel results on the spatial inclination of the pterygoid process, and reconciled machine learning with non-Bayesian models, the application of which belongs to the realm of oral-maxillofacial surgery.
