Entanglements of infrastructure, resources, and community politics in northeast India : a study of the Patkai Hills, Arunachal Pradesh Wangsu, Manta; Nair, Gayatri (Advisor) Based on the ethnography of the Tangsas conducted from July 2022 to September 2023, this study examines the operations of the informal coal industry in the Patkai Hills region of Arunachal Pradesh, involving multiple actors, including the community, the state, and non-state actors such as armed groups and external private players. It explores the interplay between the extractive process of the coal industry and road infrastructure, focusing on how the community is impacted by this and their perceptions of development. The study reveals the specific political, infrastructural, and economic conditions under which a formal coal industry transitioned to informal coal operations. In doing so, it interrogates what constitutes the region’s politics of regulations and deregulations within the larger political economy of development. The study also highlights the evolving socioeconomic dynamics within the Tangsa community, particularly in relation to changing landholding practices, ecological implications, livelihood crises, and widening intra-community inequality, among other issues that have been shaped by this shift. The findings of this study further indicate how participation in the region’s informal coal economy is primarily determined by distinct social locations within the community, political positions, and economic circumstances. Rather than viewing all the involved actors as homogeneously complicit, the study illuminates the ground realities where the larger sections of the Tangsa community remain excluded from equitable benefits despite their involvement in the extractive process, while influential local elites secure disproportionate profits. The study situates this phenomenon within the region's broader context of development interventions and resource politics, demonstrating how informal coal mining manifests as extractivism, driven by the penetration of external capital and changing internal social dynamics among the Tangsas. Ultimately, it explores the relationships between an emerging ecological crisis and widening intra-community inequalities among the Tangsas stemming from the informal coal operations in the Kharsang area of the Patkai Hills region.

Gray matter volume correlates of the spatial distribution of visual attention in high trait anxiety Chakrabarty, Mrinmoy (Advisor); Mir, Suhail Rafiq; Singh, Varsha (Advisor) Flexible allocation of attentional resources to different spatial loci is crucial to meet the demands of a dynamic environment that we navigate daily. The inability to adaptively redistribute spatial attention may lead to constricted or tunnel vision, which may compromise sampling the span of the visual field towards optimizing visually guided behaviour. This is of interest in anxious individuals, who are known to have biases in visual processing. We used a modified affect-primed, visual-spatial behavioural attention task with structural magnetic resonance imaging (sMRI) in a sample of healthy young adults with varying degrees of trait(dispositional) anxiety (n = 60 with 23 females; age [mean ± s.d.] = 22.8 ± 3.8; trait anxiety [mean ± s.d.] = 46.52 ± 11.04). Using objective measures from the behavioural task and sMRI, we explored if a) fear and neutral affect from image primes differed relative to no affect (scrambled image prime) in modulating the distribution of visual spatial attention; b) an association existed between the gray matter volume (GMV) of any particular region(s) of the whole brain and a measure of the spatial distribution of attention by individual valences of affect and overall.

Memory of emotional events under cognitive load influence resting state functional brain connectivity in subclinical anxiety Kinger, Shruti; Chakrabarty, Mrinmoy (Advisor) Memory suppression is an active process that voluntarily prevents the intrusion of undesirable memories into one's conscious awareness. However, the process may trigger ironic effects, meaning such suppressed memories become more accessible to the conscious mind. Cognitive load is one of the factors contributing to ironic effects. The influence of directed remembering and suppression of emotionally valenced memories under cognitive load in anxiety are sparse in the literature, to our knowledge. We, therefore, measured whether the directed remembering/recall or suppression of emotionally valenced memories impact an independent visual working memory task (imposing a cognitive load) in healthy young adults with dispositional/subclinical anxiety and its association with resting state functional connectivity (rsfc).

Mapping fear affect and inhibitory control in young adult brains : insights from resting-state functional connectivity Kinger, Shruti; Suri, Kapali; Chakrabarty, Mrinmoy (Advisor) The cognitive component of anxiety, measured using the Fear Affect scale of the National Institutes of Health toolbox, stems from perceived threats of events distant in space and time. Since anxiety is known to impact higher cognitive functions in daily life, potentially leading to cognitive behavioural disorders, we aimed to identify salient whole-brain resting state functional connectivity (rsfc) patterns that explain the negative affect associated with it and the role it plays in influencing the rsfc patterns related to an aspect of executive function (inhibitory control on visual distractors) using Human Connectome Project dataset. The results show a few key resting-state functional brain networks associated with fear-affect. Conference: Society for Neuroscience 2024, Chicago, USA - October 5-9, 2024.
