Subjective norms as a mediator between exposure to online alcohol and marijuana content and offline use among adolescents

Julie V. Cristello, Dana M. Litt, Matthew T. Sutherland, Elisa M. Trucco

Drug and Alcohol Review > 43 > 1 > 111 - 121

Introduction While adolescent substance use (SU) may be viewed as normative, SU can quickly escalate leading to consequences. Social media use may increase SU risk. Despite using social media to connect with others, adolescents also view depictions of glamorised SU by both peers and influential figures. Exposure to online alcohol and marijuana content may impact subjective norms (i.e., injunctive...

Meta-analytic evidence for a core problem solving network across multiple representational domains

Jessica E. Bartley, Emily R. Boeving, Michael C. Riedel, Katherine L. Bottenhorn, more

Neuroscience & Biobehavioral Reviews > 2018 > 92 > C > 318-337

Problem solving is a complex skill engaging multi-stepped reasoning processes to find unknown solutions. The breadth of real-world contexts requiring problem solving is mirrored by a similarly broad, yet unfocused neuroimaging literature, and the domain-general or context-specific brain networks associated with problem solving are not well understood. To more fully characterize those brain networks,...

Top-Down Versus Bottom-Up Processing in the Human Brain: Distinct Directional Influences Revealed by Integrating SOBI and Granger Causality

Akaysha C. Tang, Matthew T. Sutherland, Peng Sun, Yan Zhang, more

Lecture Notes in Computer Science > Independent Component Analysis and Signal Separation > Miscellaneous > 802-809

Top-down and bottom-up processing are two distinct yet highly interactive modes of neuronal activity underlying normal and abnormal human cognition. Here we characterize the dynamic processes that contribute to these two modes of cognitive operation. We used a blind source separation algorithm called second-order blind identification (SOBI [1]) to extract from high-density scalp EEG (128 channels)...

Michael C. Riedel, Kimberly L. Ray, Anthony S. Dick, Matthew T. Sutherland, more

NeuroImage > 2015 > 117 > C > 327-342

The cerebellum historically has been thought to mediate motor and sensory signals between the body and cerebral cortex, yet cerebellar lesions are also associated with altered cognitive behavioral performance. Neuroimaging evidence indicates that the cerebellum contributes to a wide range of cognitive, perceptual, and motor functions. Here, we used the BrainMap database to investigate whole-brainco-activation...

Greater externalizing personality traits predict less error‐related insula and anterior cingulate cortex activity in acutely abstinent cigarette smokers

Allison J. Carroll, Matthew T. Sutherland, Betty Jo Salmeron, Thomas J. Ross, more

Addiction Biology > 20 > 2 > 377 - 389

Attenuated activity in performance‐monitoring brain regions following erroneous actions may contribute to the repetition of maladaptive behaviors such as continued drug use. Externalizing is a broad personality construct characterized by deficient impulse control, vulnerability to addiction and reduced neurobiological indices of error processing. The insula and dorsal anterior cingulate cortex (dACC)...

Down-Regulation of Amygdala and Insula Functional Circuits by Varenicline and Nicotine in Abstinent Cigarette Smokers

Matthew T. Sutherland, Allison J. Carroll, Betty Jo Salmeron, Thomas J. Ross, more

Biological Psychiatry > 2013 > 74 > 7 > 538-546

Although the amygdala and insula are regarded as critical neural substrates perpetuating cigarette smoking, little is known about their circuit-level interactions with interconnected regions during nicotine withdrawal or following pharmacotherapy administration. To elucidate neurocircuitry associated with early smoking abstinence, we examined the impact of varenicline and nicotine, two modestly efficacious...

Individual differences in amygdala reactivity following nicotinic receptor stimulation in abstinent smokers

Matthew T. Sutherland, Allison J. Carroll, Betty Jo Salmeron, Thomas J. Ross, more

NeuroImage > 2013 > 66 > Complete > 585-593

Hyperactive amygdala functioning may underlie emotional dysregulation during smoking abstinence and represents one neurobiological target for pharmacological cessation aids. Available pharmacotherapies (e.g., nicotine replacement and varenicline) aid only a subset of individuals with smoking cessation and therefore elucidating the neurobiological impact of these medications is critical to expedite...

Reliable detection of bilateral activation in human primary somatosensory cortex by unilateral median nerve stimulation

Matthew T. Sutherland, Akaysha C. Tang

NeuroImage > 2006 > 33 > 4 > 1042-1054

In non-human primates, a bilateral representation of unilaterally presented somatosensory information can be found at the lowest level of cortical processing as indicated by the presence of neurons with bilateral receptive fields in the hand region of primary somatosensory (SI) cortex. In humans, such bilateral activation of SI is considered controversial due to highly variable detection rates for...

Akaysha C. Tang, Matthew T. Sutherland, Christopher J. McKinney

NeuroImage > 2005 > 25 > 2 > 539-553

Second-order blind identification (SOBI) is a blind source separation (BSS) algorithm that can be used to decompose mixtures of signals into a set of components or putative recovered sources. Previously, SOBI, as well as other BSS algorithms, has been applied to magnetoencephalography (MEG) and electroencephalography (EEG) data. These BSS algorithms have been shown to recover components that appear...
