Thanks to patients Phineas Gage and Henry Molaison, we have long known that behavioral control depends on the frontal lobes, whereas declarative memory depends on the medial temporal lobes. For decades, cognitive functions – behavioral control, declarative memory – have served as labels for characterizing the division of labor in cortex. This approach has made enormous contributions to understanding how the brain enables the mind, providing a systems-level explanation of brain function that constrains lower-level investigations of neural mechanism. Today, the approach has evolved such that functional labels are often applied to brain networks rather than focal brain regions. Furthermore, the labels have diversified to include both broadly-defined cognitive functions (declarative memory, visual perception) and more circumscribed mental processes (recollection, familiarity, priming). We ask whether a process – a high-level mental phenomenon corresponding to an introspectively-identifiable cognitive event – is the most productive label for dissecting memory. For example, the process of recollection conflates a neurocomputational operation (pattern completion-based retrieval) with a class of representational content (associative, high-dimensional, episodic-like memories). Because a full theory of memory must identify operations and representations separately, and specify how they interact, we argue that processes like recollection constitute inadequate labels for characterizing neural mechanisms. Instead, we advocate considering the component operations and representations of mnemonic processes in isolation, when examining their neural underpinnings. For the neuroanatomical organization of memory, the evidence suggests that pattern completion is recapitulated widely across cortex, but the division of labor between cortical sites can be explained by representational content.

This chapter is an extended revision of the authors' earlier study (2016) on the training routines of professional and high-level esport players, with added focus on their physical exercise. The study is methodologically mixed with a quantitative survey sample (n=115) and a qualitative interview sample (n=7). Based on this data, high-level esport players train approximately 5.28 hours every day around the year, and professional esport players at least the same amount. Approximately 1.08 hours of that training is physical exercise. More than half (55.6%) of the professional and high-level esport players believe that integrating physical exercise into their training programs has a positive effect on esport performance; however, no less than 47.0% do the physical exercise chiefly to maintain their overall state of health. Accordingly, the study indicates that professional and high-level esport players are physically active as well: those of age 18 and older exercising more than three times the daily 21-minute physical activity recommendation given by the World Health Organization.

AbstractTwo of the roles assigned to the basal ganglia in spoken language parallel very well their contribution to motor behaviour: (1) their role in sequence processing, resulting in syntax deficits, and (2) their role in movement “vigor,” leading to “hypokinetic dysarthria” or “hypophonia.” This is an additional example of how the motor system has served the emergence of high-level cognitive functions, such as language.

Creativity And Innovation

Human beings are the only mammals to be able to utilize high-level cognitive functions to build knowledge, innovate, and communicate their complex ideas. Imagination, creativity, and innovation are interlinked in the sense that one leads to the other. This chapter details the concepts of imagery, imagination, and creativity and their inter-relationships in the first section. Next, the author discusses the historical perspectives of imagination pertaining to the accounts of famous philosophers and psychologists like Aristotle, Kant, Hume, Descartes, Sartre, Husserl, and Wittgenstein. Section 3 and 4 present the neuro-biological correlates of imagination and creativity, respectively. Brain regions, neuronal circuits, genetic basis, as well as the evolutionary perspective of imagination and creativity are elicited in these sections. Finally, creativity and innovation are explored as to how they will contribute to knowledge build-up and advances in science, engineering, and business in the fourth industrial revolution and the imagination age.

BackgroundYoga and physical exercise have been used as adjunctive intervention for cognitive dysfunction in schizophrenia (SZ), but controlled comparisons are lacking.AimsA single-blind randomised controlled trial was designed to evaluate whether yoga training or physical exercise training enhance cognitive functions in SZ, based on a prior pilot study.MethodsConsenting, clinically stable, adult outpatients with SZ (n=286) completed baseline assessments and were randomised to treatment as usual (TAU), supervised yoga training with TAU (YT) or supervised physical exercise training with TAU (PE). Based on the pilot study, the primary outcome measure was speed index for the cognitive domain of ‘attention’ in the Penn computerised neurocognitive battery. Using mixed models and contrasts, cognitive functions at baseline, 21 days (end of training), 3 and 6 months post-training were evaluated with intention-to-treat paradigm.ResultsSpeed index of attention domain in the YT group showed greater improvement than PE at 6 months follow-up (p<0.036, effect size 0.51). In the PE group, ‘accuracy index of attention domain showed greater improvement than TAU alone at 6-month follow-up (p<0.025, effect size 0.61). For several other cognitive domains, significant improvements were observed with YT or PE compared with TAU alone (p<0.05, effect sizes 0.30–1.97).ConclusionsBoth YT and PE improved attention and additional cognitive domains well past the training period, supporting our prior reported beneficial effect of YT on speed index of attention domain. As adjuncts, YT or PE can benefit individuals with SZ.

Abstract Objectives: The main aim of this meta-analysis was to compare the effects of different physical activities on cognitive functions in older adults divided according to cognitive impairment levels. Methods: We searched Web of Science, Scopus, and PubMed for randomized control trials (RCT). A standardized mean difference (SMD) of the pre-post intervention score of global cognitive function tests were calculated by the random model in the Cochrane meta-analyses for people with cognitive impairment generally and across three levels - mild, mild to moderate, and moderate to severe cognitive impairment separately. Additionally, an unstandardized coefficient beta (B) was calculated in generalized linear models to estimate the effects of exercise, cognitive impairment severity, age, female ratio, length of intervention, and time of exercise a week on the global cognitive function. Results: Data from 26 studies involving 1,137 participants from intervention groups and 1,187 participants from control groups were analyzed. Physical exercise had a positive effect on cognitive functions in people across all levels of cognitive impairments SMD (95 % confidence interval [CI]) = 1.19 (0.77 - 1.62); however, heterogeneity was considerably high I 2 = 95%. Aerobic (B = 8.881) and resistance exercise (B = 4.464) was significantly associated with better results in global cognitive functions when compared to active control. A higher number of female participants cin intervention groups had a statistically significant effect on the global cognitive function (B = 0.229). onclusions: Physical exercise was associated with cognitive function improvement in older people with cognitive impairments. Aerobic exercise was more strongly associated than resistance exercise to combat cognitive decline. Keywords: Physical activity, Dementia, Aging, Meta-analysis, Aerobic exercise, Cognitive function

Abstract Functional Magnetic Resonance Imaging (fMRI) has furthered brain mapping on perceptual, motor, as well as higher-level cognitive functions. However, to date, no data collection has systematically addressed the functional mapping of cognitive mechanisms at a fine spatial scale. The Individual Brain Charting (IBC) project stands for a high-resolution multi-task fMRI dataset that intends to provide the objective basis toward a comprehensive functional atlas of the human brain. The data refer to a cohort of 12 participants performing many different tasks. The large amount of task-fMRI data on the same subjects yields a precise mapping of the underlying functions, free from both inter-subject and inter-site variability. The present article gives a detailed description of the first release of the IBC dataset. It comprises a dozen of tasks, addressing both low- and high- level cognitive functions. This openly available dataset is thus intended to become a reference for cognitive brain mapping.
