Novelty-seeking and directed exploration scale with dissociable social network outcomes and brain systems in older adults

Christian Valtierra, Jeremy Hogeveen, Gabriella Mace, Samantha Moreno, Avery E. Ostrand, Sydney Griffith, Maria Jose Auil, Patrick A. McConnell, J Chen, Jennifer Mitchell, Gary R. Turner, Nathan Spreng, Adam H. Gazzaley, Lorenzo Pasquini

This study links undirected novelty seeking and goal-directed exploration in older adults to distinct social network outcomes and brain systems using fMRI and a social bandit reinforcement task.

Longitudinal changes in control energy of brain networks in older adults at familial risk for Alzheimers disease

Paulina Skolasinska, Alfie R. Wearn, Daniel O'Sullivan, Isabella C. Stallworthy, Julia K. Brynildsen, Ilana Ruth Leppert, Christine Lucas Tardif, Gary R. Turner, Dani S. Bassett, R. Nathan Spreng

This study examines how control energy in brain networks changes over time in older adults at risk for Alzheimer's disease, finding specific patterns linked to cognitive performance and biomarkers.

Thalamocortical orchestration of human theory of mind

Runhao Lu, Emily J Davidson, Jonah Miller-Smith, Dian Lyu, Zoe Lusk, Prantik Kundu, Julien Doyon, Xiaoqian J. Chai, Boris C. Bernhardt, Gary R. Turner, R. Nathan Spreng

This paper investigates thalamocortical dynamics during theory of mind tasks using fMRI and sEEG, finding that the thalamus coordinates default network activity through phase-amplitude coupling without local activation.

The neural basis of cost-benefit trade-offs in effort investment: a quantitative activation likelihood estimation meta-analysis

Nathaniel Edgar, Kevin da Silva Castanheira, Gary R. Turner, R. Nathan Spreng, Eliana Vassena, A. Ross Otto

This study uses meta-analysis to show that mPFC/dACC processes task demand and reward separately, with caudal regions integrating them to reflect cost-benefit trade-offs in effort investment.

Cholinergic synaptic plasticity shapes resilience and vulnerability to tau

Kate M. Onuska, Hayley R.C. Shanks, Lauren A. Devito, Qi Qi, Alycia M Crooks, Liliana Germán-Castelán, Geoffrey N. Ngo, Roy A.M. Haast, Tallulah S. Andrews, Kayla M. Williams, Flávio H. Beraldo, Ting Qiu, Alfonso Fajardo-Valdez, Jordana Remz, Alfie Wearn, , Taylor W. Schmitz

The paper shows that cholinergic synaptic plasticity, specifically VAChT responses to tau, correlates with cognitive resilience in presymptomatic AD.

The biological role of local and global fMRI BOLD signal variability in human brain organization

Giulia Baracchini, Yigu Zhou, Jason da Silva Castanheira, Justine Y. Hansen, Jenny R Rieck, Gary R. Turner, Cheryl L. Grady, Bratislav Mišić, Jason S. Nomi, Lucina Q. Uddin, R. Nathan Spreng

This study investigates the variability of fMRI BOLD signals in the human brain, showing it reflects multi-scale brain organization rather than noise.

Taking stock of the past: A psychometric evaluation of the Autobiographical Interview

Amber W. Lockrow, Roni Setton, Karen A.P. Spreng, Signy Sheldon, Gary R. Turner, R. Nathan Spreng

The paper evaluates the psychometric properties of the Autobiographical Interview in healthy adults, finding strong reliability and convergent validity but limited support for its two-factor structure.

Age differences in the functional architecture of the human brain

Roni Setton, Laetitia Mwilambwe-Tshilobo, Manesh Girn, Amber W. Lockrow, Giulia Baracchini, Colleen S. Hughes, Alexander J. Lowe, Benjamin N. Cassidy, Jian Li, Wen‐Ming Luh, Danilo Bzdok, Richard M. Leahy, Tian Ge, Daniel S. Margulies, Bratislav Mišić, , R. Nathan Spreng

This study examines age-related changes in brain functional architecture using multi-scale fMRI analyses in younger and older adults, finding both global and network-specific dedifferentiation patterns.
