Poe and the Sciences of the Brain

Author(s):  
Paul Gilmore

This chapter examines Poe’s exploration of how the human brain functions in his critical essays and tales. It locates his ideas concerning the brain’s functions within mid-nineteenth-century theories about the mind and the brain, specifically phrenology, and alongside his description of intuition as an alternative or supplement to a scientific epistemology based purely in induction and deduction. After doing so, it theorizes how his views might intersect with recent developments in neuroscience and the cognitive sciences, especially as applied to aesthetics. Like many other Romantic authors, Poe approached scientific pursuits and methods, especially those regarding human mental faculties and functions, with both skepticism and a great deal of interest. Ranging over a number of Poe’s works, from Eureka to “The Imp of the Perverse,” “Murders in the Rue Morgue” to “Philosophy of Composition,” the chapter argues that Poe’s celebration and critique of human rationality and the limits of scientific methods, especially in regards to the human brain, provide a valuable template for thinking through the application of developments in brain science to literary-aesthetic questions in the twenty-first century.

Injuries and hidden dangers in training have a greater impact on athletes ’careers. In particular, the brain function that controls the motor function area has a greater impact on the athlete ’s competitive ability. Based on this, it is necessary to adopt scientific methods to recognize brain functions. In this paper, we study the structure of motor brain-computer and improve it based on traditional methods. Moreover, supported by machine learning and SVM technology, this study uses a DSP filter to convert the preprocessed EEG signal X into a time series, and adjusts the distance between the time series to classify the data. In order to solve the inconsistency of DSP algorithms, a multi-layer joint learning framework based on logistic regression model is proposed, and a brain-machine interface system of sports based on machine learning and SVM is constructed. In addition, this study designed a control experiment to improve the performance of the method proposed by this study. The research results show that the method in this paper has a certain practical effect and can be applied to sports.

Abstract J.T. Fraser used to emphasize the uniqueness of the human brain in its capacity for apprehending the various dimensions of “nootemporality” (Fraser 1982 and 1987). Indeed, our brain allows us to sense the flow of time, to measure delays, to remember past events or to predict future outcomes. In these achievements, the human brain reveals itself far superior to its animal counterpart. Women and men are the only beings, I believe, who are able to think about what they will do the next day. This is because such a thought implies three intellectual abilities that are proper to mankind: the capacity to take their own thoughts as objects of their thinking, the ability of mental time travels—to the past thanks to their episodic memory or to the future—and the possibility to project very far into the future, as a consequence of their enlarged and complexified forebrain. But there are severe limits to our timing abilities of which we are often unaware. Our sensibility to the passing time, like other of our intellectual abilities, is often competing with other brain functions, because they use at least in part the same neural networks. This is particularly the case regarding attention. The deeper the level of attention required, the looser is our perception of the flow of time. When we pay attention to something, when we fix our attention, then our inner sense of the flux of time freezes. This limitation should not sound too unfamiliar to the reader of J.T. Fraser who wrote in his book Time, Conflict, and Human Values (1999) about “time as a nested hierarchy of unresolvable conflicts.”

See Vértes and Seidlitz (doi:10.1093/brain/awz353) for a scientific commentary on this article. Is schizophrenia a by-product of human brain evolution? By comparing the human and chimpanzee connectomes, van den Heuvel et al. demonstrate that connections unique to the human brain show greater involvement in schizophrenia pathology. Modifications in service of higher-order brain functions may have rendered the brain more vulnerable to dysfunction.

Emotions are traditionally viewed as detrimental to judicial responsibility, a belief rooted in the classical view of the mind as a battle ground between reason and emotion. Drawing on recent developments in psychology and neuroscience we propose that the brain uses past experience, organized as concepts, to guide actions and give sensations meaning, constructing experiences such as “fear” or “anger”. Wisdom comes from skill at constructing emotions in a more precise and functional way, a skill called “emotional granularity”. Studies show that individuals who are more emotionally granular have better function across a range of domains, including self regulation and decision making. We propose that effective judicial decision-making does not require a dispassionate judge, but a judge who is high in emotional granularity. We lay out an empirical agenda for testing this idea and end by discussing empirically supported recommendations for increasing emotional granularity in the judiciary. Tradicionalmente, se ha considerado que las emociones son perjudiciales para el desempeño responsable de la labor judicial, una creencia enraizada en la concepción clásica de la mente como campo de batalla entre razón y emoción. Partiendo de nuevos descubrimientos en psicología y neurociencia, argumentamos que el cerebro usa la experiencia pasada, organizada como conceptos, para guiar las acciones y dar sentido a las sensaciones, construyendo experiencias como “miedo” o “ira”. La sabiduría proviene de la habilidad en construir emociones de un modo más preciso y funcional, habilidad denominada “granularidad emocional”. Los estudios muestran que los individuos más granulares emocionalmente funcionan mejor en varios dominios, incluyendo la autorregulación y la toma de decisiones. Argumentamos que la toma de decisiones eficaz en judicatura no requiere de un juez desapasionado, sino de un juez que tenga alta granularidad emocional. Proponemos un programa empírico para poner a prueba esa idea, y concluimos con un debate de recomendaciones de base empírica para aumentar la granularidad emocional en la judicatura.

Recent advances in neurotechnology allow for an increasingly tight integration of the human brain and mind with artificial cognitive systems, blending persons with technologies and creating an assemblage that we call a hybrid mind. In some ways the mind has always been a hybrid, emerging from the interaction of biology, culture (including technological artifacts) and the natural environment. However, with the emergence of neurotechnologies enabling bidirectional flows of information between the brain and AI-enabled devices, integrated into mutually adaptive assemblages, we have arrived at a point where the specific examination of this new instantiation of the hybrid mind is essential. Among the critical questions raised by this development are the effects of these devices on the user’s perception of the self, and on the user’s experience of their own mental contents. Questions arise related to the boundaries of the mind and body and whether the hardware and software that are functionally integrated with the body and mind are to be viewed as parts of the person or separate artifacts subject to different legal treatment. Other questions relate to how to attribute responsibility for actions taken as a result of the operations of a hybrid mind, as well as how to settle questions of the privacy and security of information generated and retained within a hybrid mind.

Brain research is intended to produce valuable results in medicine and information technology. All to the good. Nevertheless, the contentions made by both the BRAIN Initiative and the Human Brain Project are not only unproven, but indefensible. Their most egregious error lies in a doctrinal misconception of what the mind does. The mind is a matter of memory, belief, intention, desire, will, and the like—mentalities.

Eyes as the unique organ possess intensively direct connections to the brain and dynamically perceptual accessibility to the mind. This paper analyzes the cognitive mechanisms of eyes not only as the sensory of vision, but also the browser of internal memory in thinking and perception. The browse function of eyes is created by abstract conditioning of the eye's tracking pathway for accessing internal memories, which enables eye movements to function as the driver of the perceptive thinking engine of the brain. The dual mechanisms of the eyes as both the external sensor of the brain and the internal browser of the mind are explained based on evidences and cognitive experiences in cognitive informatics, neuropsychology, cognitive science, and brain science. The finding on the experiment's internal browsing mechanism of eyes reveals a crucial role of eyes interacting with the brain for accessing internal memory and the cognitive knowledge base in thinking, perception, attention, consciousness, learning, memorization, and inference.

Abstract The human brain is the most complex organ consisting of billions of neuronal and non-neuronal cells that are organized into distinct anatomical and functional regions. Elucidating the cellular and transcriptome architecture underlying the brain is crucial for understanding brain functions and brain disorders. Thanks to the single-cell RNA sequencing technologies, it is becoming possible to dissect the cellular compositions of the brain. Although great effort has been made to explore the transcriptome architecture of the human brain, a comprehensive database with dynamic cellular compositions and molecular characteristics of the human brain during the lifespan is still not available. Here, we present STAB (a Spatio-Temporal cell Atlas of the human Brain), a database consists of single-cell transcriptomes across multiple brain regions and developmental periods. Right now, STAB contains single-cell gene expression profiling of 42 cell subtypes across 20 brain regions and 11 developmental periods. With STAB, the landscape of cell types and their regional heterogeneity and temporal dynamics across the human brain can be clearly seen, which can help to understand both the development of the normal human brain and the etiology of neuropsychiatric disorders. STAB is available at http://stab.comp-sysbio.org.

Imaging of the structure and function of the human brain has grown to an area with increasing impact on neuropsychological research as well as on the routine clinical evaluation of brain damaged patients. The scientific and popular literature is now flooded by increasingly more spectacular pictures of the brain. The images no longer only illustrate what is well known from earlier research but they do also sometimes provide information of importance for the further development of neuropsychological theories. The two volumes edited by Erin D. Bigler, Neuroimaging I and II, offer a possibility for neuropsychologists and other interested readers to get acquainted with the more recent developments in measurement technology and applications in basic science (Volume I) as well as in the clinic (Volume II). The authors of the 24 chapters are generally outstanding researchers, with impressive expertise within their fields of specialization.

AbstractThe extent to which brain functions are localized or distributed is a foundational question in neuroscience. In the human brain, common fMRI methods such as cluster correction, atlas parcellation, and anatomical searchlight are biased by design toward finding localized representations. Here we introduce the functional searchlight approach as an alternative to anatomical searchlight analysis, the most commonly used exploratory multivariate fMRI technique. Functional searchlight removes any anatomical bias by grouping voxels based only on functional similarity and ignoring anatomical proximity. We report evidence that visual and auditory features from deep neural networks and semantic features from a natural language processing model are more widely distributed across the brain than previously acknowledged. This approach provides a new way to evaluate and constrain computational models with brain activity and pushes our understanding of human brain function further along the spectrum from strict modularity toward distributed representation.
