Conceptualization of Space within the Tang Landscape Quatrain

The thesis explores the poet’s creation of conceptualized space within the Tang landscape quatrain in the Tang dynasty (618-907) by usage of literary techniques, the focal point being that of temporal and spatial progression to create dynamic and static space. “Space” within the thesis is defined as the “matrix of which forms emerge, medium in which they are related,” a mentalization and visualization of breadth, depth, and width created within the artistic medium. I argue that the concision of Classical Chinese allows the poet to transcend the linguistic limitations imposed by rules of verse to create boundless, semantic space by constructing vivid tableaus of scene and emotion. In Classical Chinese, there are no verb tenses, no indication of plurality in nouns, and no gender or cases for pronouns. The poet must use language to mold intangible form into tangible existence. The deliberate application of ambiguity is a vital component in the creation of multi-layered dimensions of space within Classical Chinese poetry. The Tang dynasty is often known as the golden age of Chinese poetry, dominated by the emergence of new innovations and form as poetry writing became more ubiquitous. The breaking from traditional rules of verse allowed the poet to uniquely utilize space to further their reflections in their poetry. The thesis examines the poet’s creation of spatiality through two lenses of spatiality: creation of external space through landscape, and secondly, the creation of internal space through mental reflection upon that very landscape. The Tang poet approaches the landscape not only as a place setting, but also as an entire subliminal entity in which he aims to capture with his senses and perceptions to create space in which the reader can visualize. The descriptive poetry of the landscape quatrain is simply not a limitation as a medium of visual communication as Tang poets infuse layers of meaning with the economy of a few characters. The significance of framing this study within traditional poetic concerns is to understand the intersections of nature, landscape, literary technique, and aesthetic experience. There has been much academic scholarship on the poetry of the High Tang by scholars such as James J. Y. Liu, Stephen Owen, Burton Watson, just to name a few. However, the objective of this thesis is to offer a new perspective through the lens of spatial creation. Quatrains written by famous Tang poets, Li Bai (701-762), Wang Wei (701-761), and Meng Haoran (689-740) are selected to illustrate how the technique of progression is uniquely utilized to create depth and perspective of space.Asian Studie

Mental imagery of positive and neutral memories : a fMRI study comparing field perspective imagery to observer perspective imagery

Imagery perspective can influence what information is recalled, processing style, and emotionality; however, the understanding of possible mechanisms mediating these observed differences is still limited. We aimed to examine differences between memory recall from a field perspective and observer perspective at the neurobiological level, in order to improve our understanding of what is underlying the observed differences at the behavioral level. We conducted a fMRI study in healthy individuals, comparing imagery perspectives during recall of neutral and positive autobiographical memories. Behavioral results revealed field perspective imagery of positive memories, as compared to observer perspective, to be associated with more positive feelings afterwards. At the neurobiological level, contrasting observer perspective to field perspective imagery was associated with greater activity, or less decrease relative to the control visual search task, in the right precuneus and in the right temporoparietal junction (TPJ). Greater activity in the right TPJ during an observer perspective as compared to field perspective could reflect performing a greater shift of perspective and mental state during observer perspective imagery than field perspective imagery. Differential activity in the precuneus may reflect that during observer perspective imagery individuals are more likely to engage in (self-) evaluative processing and visuospatial processing. Our findings contribute to a growing understanding of how imagery perspective can influence the type of information that is recalled and the intensity of the emotional response. Observer perspective imagery may not automatically reduce emotional intensity but this could depend on how the imagined situation is evaluated in relation to the self-concept. (C) 2016 Elsevier Inc.

Transcranial Focused Ultrasound to the Right Prefrontal Cortex Improves Mood and Alters Functional Connectivity in Humans

Transcranial focused ultrasound (tFUS) is an emerging method for non-invasive neuromodulation akin to transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). tFUS offers several advantages over electromagnetic methods including high spatial resolution and the ability to reach deep brain targets. Here we describe two experiments assessing whether tFUS could modulate mood in healthy human volunteers by targeting the right inferior frontal gyrus (rIFG), an area implicated in mood and emotional regulation. In a randomized, placebo-controlled, double-blind study, participants received 30 s of 500 kHz tFUS or a placebo control. Visual Analog Mood Scales (VAMS) assessed mood four times within an hour (baseline and three times after tFUS). Participants who received tFUS reported an overall increase in Global Affect (GA), an aggregate score from the VAMS scale, indicating a positive shift in mood. Experiment 2 examined resting-state functional (FC) connectivity using functional magnetic resonance imaging (fMRI) following 2 min of 500 kHz tFUS at the rIFG. As in Experiment 1, tFUS enhanced self-reported mood states and also decreased FC in resting state networks related to emotion and mood regulation. These results suggest that tFUS can be used to modulate mood and emotional regulation networks in the prefrontal cortex

Bayesian log-Gaussian Cox process regression: applications to meta-analysis of neuroimaging working memory studies

Working memory (WM) was one of the first cognitive processes studied with functional magnetic resonance imaging. With now over 20 years of studies on WM, each study with tiny sample sizes, there is a need for meta-analysis to identify the brain regions that are consistently activated by WM tasks, and to understand the interstudy variation in those activations. However, current methods in the field cannot fully account for the spatial nature of neuroimaging meta-analysis data or the heterogeneity observed among WM studies. In this work, we propose a fully Bayesian random-effects metaregression model based on log-Gaussian Cox processes, which can be used for meta-analysis of neuroimaging studies. An efficient Markov chain Monte Carlo scheme for posterior simulations is presented which makes use of some recent advances in parallel computing using graphics processing units. Application of the proposed model to a real data set provides valuable insights regarding the function of the WM
