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.

Exploring the tapestry of grief : a multimodal analysis of grief in social fabric Mittal, Shefali; Prince, Deepak (Advisor) The unavoidable aspects of loss and grief are explored in this study project, which acknowledges their significant influence on shared experiences within communities, societal dynamics, and mental health. The project intends to aid in the mending of society by investigating the far-reaching impacts of loss and grief. Urgent talks are required in light of the spike in mental health issues, which has caused a shift in perspective from seeing these issues as solely personal struggles to acknowledging larger cultural impacts. The research, which takes a social perspective on mourning, recognises grief as a societal fabric that weaves together personal stories and builds bonds. Through the use of a multimodal approach that incorporates auto-ethnography, critical cinema analysis, and structured interview, the study looks at various mourning landscapes that are impacted by cultural dynamics and socioeconomic considerations. It seeks to advance awareness of mental health issues through this perspective, promoting social healing and group comprehension.
