Autor: Nidhi V. Banavar, Sharon M. Noh, Christopher N. Wahlheim, Brittany S. Cassidy, C. Brock Kirwan, Craig E. L. Stark, Aaron M. Bornstein

Publikováno v: Frontiers in Human Neuroscience, Vol 18 (2024)

IntroductionThe Mnemonic Similarity Task (MST) is a widely used measure of individual tendency to discern small differences between remembered and presently presented stimuli. Significant work has established this measure as a reliable index of neuro

Evidence for a single rather than a triple dissociation in the medial temporal lobe: An fMRI recognition memory replication study

Autor: Julie Van, Sam E. Nielsen, C. Brock Kirwan

Publikováno v: Neuroimage: Reports, Vol 2, Iss 4, Pp 100135- (2022)

Common research practices in neuroimaging studies using functional magnetic resonance imaging may produce outcomes that are difficult to replicate. Results that cannot be replicated have contributed to a replication crisis in psychology, neuroscience

Repetition of Computer Security Warnings Results in Differential Repetition Suppression Effects as Revealed With Functional MRI

Autor: C. Brock Kirwan, Daniel K. Bjornn, Bonnie Brinton Anderson, Anthony Vance, David Eargle, Jeffrey L. Jenkins

Publikováno v: Frontiers in Psychology, Vol 11 (2020)

Computer users are often the last line of defense in computer security. However, with repeated exposures to system messages and computer security warnings, neural and behavioral responses show evidence of habituation. Habituation has been demonstrate

Efficacy of weight loss intervention can be predicted based on early alterations of fMRI food cue reactivity in the striatum

Autor: Petra Hermann, Viktor Gál, István Kóbor, C. Brock Kirwan, Péter Kovács, Tamás Kitka, Zsuzsanna Lengyel, Eszter Bálint, Balázs Varga, Csongor Csekő, Zoltán Vidnyánszky

Publikováno v: NeuroImage: Clinical, Vol 23, Iss , Pp - (2019)

Increased fMRI food cue reactivity in obesity, i.e. higher responses to high- vs. low-calorie food images, is a promising marker of the dysregulated brain reward system underlying enhanced susceptibility to obesogenic environmental cues. Recently, it

The contributions of eye gaze fixations and target-lure similarity to behavioral and fMRI indices of pattern separation and pattern completion

Autor: Daniel Bjornn, Julie Van, C. Brock Kirwan

Publikováno v: Cognitive Neuroscience. 13:171-181

Pattern separation and pattern completion are generally studied in humans using mnemonic discrimination tasks such as the Mnemonic Similarity Task (MST) where participants identify similar lures and repeated items from a series of images. Failures to

Pattern separation beyond the hippocampus: A high‐resolution whole‐brain investigation of mnemonic discrimination in healthy adults

Autor: Nathan M. Muncy, Michelle I Nash, Cooper B. Hodges, C. Brock Kirwan

Publikováno v: Hippocampus. 31:408-421

Episodic memory depends on the computational process of pattern separation in order to establish distinct memory representations of similar episodes. Studies of pattern separation in humans rely on mnemonic discrimination tasks, which have been shown

Acute after-school screen time in children decreases impulse control and activation toward high-calorie food stimuli in brain regions related to reward and attention

Autor: Nathan M. Muncy, Bruce W. Bailey, Mary Efraim, Sunku Kwon, C. Brock Kirwan, Larry A. Tucker

Publikováno v: Brain Imaging and Behavior. 15:177-189

The purpose of this study was to examine the effects of after-school sedentary screen time on children’s brain activation in reward and cognitive control regions in response to pictures of high- and low-calorie foods. Thirty-two children participat

Neural mechanisms that promote food consumption following sleep loss and social stress: an fMRI study in adolescent girls with overweight/obesity

Autor: Chad D. Jensen, Johanna M. Jarcho, Kimberly A. Barnett, Kara M. Duraccio, C. Brock Kirwan, Whitney D. Allen, Nathan M. Muncy, Robyn C. Blackburn, Kelsey K. Zaugg

Publikováno v: Sleep. 45

Study Objectives Insufficient sleep and social stress are associated with weight gain and obesity development in adolescent girls. Functional magnetic resonance imaging (fMRI) research suggests that altered engagement of emotion-related neural networ
