Limitations and tradeoffs in synchronization of large-scale networks with uncertain links.

Scientific reports

Diwadkar A, Vaidya U.
PMID: 27067994
Sci Rep. 2016 Apr 12;6:21157. doi: 10.1038/srep21157.

The synchronization of nonlinear systems connected over large-scale networks has gained popularity in a variety of applications, such as power grids, sensor networks, and biology. Stochastic uncertainty in the interconnections is a ubiquitous phenomenon observed in these physical and...

Dysfunctional Activation and Brain Network Profiles in Youth with Obsessive-Compulsive Disorder: A Focus on the Dorsal Anterior Cingulate during Working Memory.

Frontiers in human neuroscience

Diwadkar VA, Burgess A, Hong E, Rix C, Arnold PD, Hanna GL, Rosenberg DR.
PMID: 25852529
Front Hum Neurosci. 2015 Mar 17;9:149. doi: 10.3389/fnhum.2015.00149. eCollection 2015.

Brain network dysfunction is emerging as a central biomarker of interest in psychiatry, in large part, because psychiatric conditions are increasingly seen as disconnection syndromes. Understanding dysfunctional brain network profiles in task-active states provides important information on network engagement...

Cavum septi pellucidi in first-episode patients and young relatives at risk for schizophrenia.

CNS spectrums

Keshavan MS, Jayakumar PN, Diwadkar VA, Singh A.
PMID: 15220858
CNS Spectr. 2002 Feb;7(2):155-8. doi: 10.1017/s1092852900017478.

Studies on schizophrenia (SZ) have documented an increased presence of cavum septi pellucidi (CSP) in individuals suffering from the illness. Moreover, the presence of CSP has been cited in support of the early neurodevelopmental hypothesis in SZ. Our objective...

From mathematics to medicine: A practical primer on topological data analysis (TDA) and the development of related analytic tools for the functional discovery of latent structure in fMRI data.

PloS one

Salch A, Regalski A, Abdallah H, Suryadevara R, Catanzaro MJ, Diwadkar VA.
PMID: 34383838
PLoS One. 2021 Aug 12;16(8):e0255859. doi: 10.1371/journal.pone.0255859. eCollection 2021.

fMRI is the preeminent method for collecting signals from the human brain in vivo, for using these signals in the service of functional discovery, and relating these discoveries to anatomical structure. Numerous computational and mathematical techniques have been deployed...

Multiomics Analysis Identifies BIRC3 as a Novel Glucocorticoid Response-Associated Gene.

The Journal of allergy and clinical immunology

Kan M, Diwadkar AR, Shuai H, Joo J, Wang AL, Ong MS, Sordillo JE, Iribarren C, Lu MX, Hernandez-Pacheco N, Perez-Garcia J, Gorenjak M, Potočnik U, Burchard EG, Pino-Yanes M, Wu AC, Himes BE.
PMID: 34971648
J Allergy Clin Immunol. 2021 Dec 28; doi: 10.1016/j.jaci.2021.11.025. Epub 2021 Dec 28.

BACKGROUND: Inhaled corticosteroid (ICS) response among patients with asthma is influenced by genetics, but biologically actionable insights based on associations have not been found. Various glucocorticoid response omics datasets are available to interrogate their biological effects.OBJECTIVE: We sought to...

Oculomotor delayed response abnormalities in young offspring and siblings at risk for schizophrenia.

CNS spectrums

Diwadkar VA, Sweeney JA, Boarts D, Montrose DM, Keshavan MS.
PMID: 15328471
CNS Spectr. 2001 Nov;6(11):899-903. doi: 10.1017/s109285290000095x.

Individuals with schizophrenia are know to demonstrate cognitive and behavioral difficulties, particularly alterations in executive functions, including working memory. It is unclear whether these deficits reflect trait-related vulnerability to schizophrenia indicators and can be assessed by studying nonpsychotic relatives...

Disordered directional brain network interactions during learning dynamics in schizophrenia revealed by multivariate autoregressive models.

Human brain mapping

Baajour SJ, Chowdury A, Thomas P, Rajan U, Khatib D, Zajac-Benitez C, Falco D, Haddad L, Amirsadri A, Bressler S, Stanley JA, Diwadkar VA.
PMID: 32436639
Hum Brain Mapp. 2020 Sep;41(13):3594-3607. doi: 10.1002/hbm.25032. Epub 2020 May 21.

Directional network interactions underpin normative brain function in key domains including associative learning. Schizophrenia (SCZ) is characterized by altered learning dynamics, yet dysfunctional directional functional connectivity (dFC) evoked during learning is rarely assessed. Here, nonlinear learning dynamics were induced...

COVID-19 Pandemic-Related Reductions in Pediatric Asthma Exacerbations Corresponded with an Overall Decrease in Respiratory Viral Infections.

The journal of allergy and clinical immunology. In practice

Sayed S, Diwadkar AR, Dudley JW, O'Brien J, Dvorin D, Kenyon CC, Himes BE, Hill DA, Henrickson SE.

BACKGROUND: Respiratory viruses, air pollutants, and aeroallergens are all implicated in worsening pediatric asthma symptoms, but their relative contributions to asthma exacerbations are poorly understood. A significant decrease in asthma exacerbations has been observed during the COVID-19 pandemic, providing...

Front Neurosci. 2017 Nov 16;11:640. doi: 10.3389/fnins.2017.00640. eCollection 2017.

To maintain thermal homeostasis, specific thermogenic tissues are under the control of central thermoregulatory networks that regulate the body's response to thermal challenges. One of these mechanisms involves non-shivering thermogenesis in brown adipose tissue (BAT), which is activated in...
