Symbolic Cognition

Symbolic behaviours such as language, music, drawing, dance, etc. are unique to humans and are found universally in every culture on earth1. These behaviours operate in different cognitive domains, but they are commonly characterised as linear sequences of symbols2,3. One of the most prominent features of language is hierarchical structure4, which is also found in music5,6 and mathematics7. Current research attempts to address whether hierarchical structure exists in drawing. When we draw complex objects, such as a face, we draw part by part in a hierarchical manner guided by visual semantic knowledge8. More specifically, we predicted how hierarchical structure emerges in drawing as follows. Although the drawing order of the constituent parts composing the target object is different amongst individuals, some parts will be drawn in succession consistently, thereby forming chunks. These chunks of parts would then be further integrated with other chunks into superordinate chunks, while showing differential affinity amongst chunks. The integration of chunks to an even higher chunk level repeats until finally reaching the full object. We analysed the order of drawing strokes of twenty-two complex objects by twenty-five young healthy adult participants with a cluster analysis9 and demonstrated reasonable hierarchical structures. The results suggest that drawing involves a linear production of symbols with a hierarchical structure. From an evolutionary point of view, we argue that ancient engravings and paintings manifest Homo sapiens’ capability for hierarchical symbolic cognition.

Neurologic Disorders

This chapter describes neurologic disorders related primarily to occupational exposures along with presenting signs and symptoms. Acute or subacute occupational exposure to high levels of neurotoxic compounds, which occurred in the past and resulted in unique presentations of neurological disorders, occur infrequently today. Sections include the evaluation of toxic neuropathies and the approach to neurobehavioral impairment along with the cognitive domains commonly affected with exposure to neurointoxicants. A section describes the approach to a patient with exposure to neurointoxicants that includes the need for a temporal association between exposure and effect, a dose-effect relationship, biological plausibility, and other causes eliminated Effects of selected neurotoxins are described, including carbon monoxide, lead, organic solvents, and manganese.

When recalling events that one personally experienced, one often visualizes the remembered scene as one originally saw it: from an internal visual perspective. Sometimes, however, one sees oneself in the remembered scene: from an external “observer perspective.” In such cases one remembers from-the-outside. This book is about such memories. Remembering from-the-outside is a common yet curious case of personal memory: one views oneself from a perspective one seemingly could not have had at the time of the original event. How can past events be recalled from a detached perspective? How is it that the self is observed? And how can we account for the self-presence of such memories? Indeed, can there be genuine memories recalled from-the-outside? If memory preserves past perceptual content then how can one see oneself from-the-outside in memory? This book disentangles the puzzles posed by remembering from-the-outside. The book develops a dual-faceted approach for thinking about memory, which acknowledges constructive and reconstructive processes at encoding and at retrieval, and it uses this approach to defend the possibility of genuine memories being recalled from-the-outside. In so doing it also elucidates the nature of such memories and sheds light on the nature of personal memory. The book argues that field and observer perspectives are different ways of thinking about a particular past event. Further, by exploring the ways we have of getting outside of ourselves in memory and other cognitive domains, the book sheds light on the nature of our perspectival minds.

Abstract Strong evidence suggests that genetic variations in DNA methyltransferases (DNMTs) may alter the downstream expression and DNA methylation patterns of neuronal genes and influence cognition. This study investigates the association between a DNMT1 polymorphism, rs2162560, and chemotherapy-associated cognitive impairment (CACI) in a cohort of breast cancer patients. This is a prospective, longitudinal cohort study. From 2011 to 2017, 351 early-stage breast cancer patients receiving chemotherapy were assessed at baseline, the midpoint, and the end of chemotherapy. DNA was extracted from whole blood, and genotyping was performed using Sanger sequencing. Patients’ self-perceived cognitive function and cognitive performance were assessed at three different time points using FACT-Cog (v.3) and a neuropsychological battery, respectively. The association between DNMT1 rs2162560 and cognitive function was evaluated using logistic regression analyses. Overall, 33.3% of the patients reported impairment relative to baseline in one or more cognitive domains. Cognitive impairment was observed in various objective cognitive domains, with incidences ranging from 7.2% to 36.9%. The DNMT1 rs2162560 A allele was observed in 21.8% of patients and this was associated with lower odds of self-reported cognitive decline in the concentration (OR = 0.45, 95% CI: 0.25–0.82, P = 0.01) and functional interference (OR = 0.48, 95% CI: 0.24–0.95, P = 0.03) domains. No significant association was observed between DNMT1 rs2162560 and objective cognitive impairment. This is the first study to show a significant association between the DNMT1 rs2162560 polymorphism and CACI. Our data suggest that epigenetic processes could contribute to CACI, and further studies are needed to validate these findings.

BACKGROUND: The majority of people living with Parkinson’s disease will develop impairments in cognition. These impairments are associated with a reduced quality of life. OBJECTIVE: The Cochrane Review aimed to investigate whether cognitive training improves cognition in people with Parkinson’s disease and mild cognitive impairments or dementia. METHODS: A Cochrane Review by Orgeta et al. was summarized with comments. RESULTS: The review included seven studies with a total of 225 participants. There was no evidence for improvements in global cognition when cognitive training was compared to control conditions. Observed improvements in attention and verbal memory measures after cognitive training could not be confirmed in a subsequent sensitivity analysis. There was no evidence for benefits in other cognitive domains or quality of life measures. The certainty of the evidence was low for all comparisons. CONCLUSIONS: The effectiveness of cognitive training for people with Parkinson’s disease and cognitive impairments remains inconclusive. There is a pressing need for adequately powered trials with higher methodological quality.

Inhibitory interneurons participate in local processing circuits, playing a central role in executive cognitive functions of the prefrontal cortex. Although humans differ from other primates in a number of cognitive domains, it is not currently known whether the interneuron system has changed in the course of primate evolution leading to our species. In this study, we examined the distribution of different interneuron subtypes in the prefrontal cortex of anthropoid primates as revealed by immunohistochemistry against the calcium-binding proteins calbindin, calretinin and parvalbumin. In addition, we tested whether genes involved in the specification, differentiation and migration of interneurons show evidence of positive selection in the evolution of humans. Our findings demonstrate that cellular distributions of interneuron subtypes in human prefrontal cortex are similar to other anthropoid primates and can be explained by general scaling rules. Furthermore, genes underlying interneuron development are highly conserved at the amino acid level in primate evolution. Taken together, these results suggest that the prefrontal cortex in humans retains a similar inhibitory circuitry to that in closely related primates, even though it performs functional operations that are unique to our species. Thus, it is likely that other significant modifications to the connectivity and molecular biology of the prefrontal cortex were overlaid on this conserved interneuron architecture in the course of human evolution.

AbstractA central property of human language is its hierarchical structure. Humans can flexibly combine elements to build a hierarchical structure expressing rich semantics. A hierarchical structure is also considered as playing a key role in many other human cognitive domains. In music, auditory-motor events are combined into hierarchical pitch and/or rhythm structure expressing affect. How did such a hierarchical structure building capacity evolve? This paper investigates this question from a bottom-up perspective based on a set of action-related components as a shared basis underlying cognitive capacities of nonhuman primates and humans. Especially, I argue that the evolution of hierarchical structure building capacity for language and music is tractable for comparative evolutionary study once we focus on the gradual elaboration of shared brain architecture: the cortico-basal ganglia-thalamocortical circuits for hierarchical control of goal-directed action and the dorsal pathways for hierarchical internal models. I suggest that this gradual elaboration of the action-related brain architecture in the context of vocal control and tool-making went hand in hand with amplification of working memory, and made the brain ready for hierarchical structure building in language and music.
