Aberrant cerebellar connectivity in motor and association networks in schizophrenia

open access: yesFrontiers in Human Neuroscience, 2015
Schizophrenia is a devastating illness characterized by disturbances in multiple domains. The cerebellum is involved in both motor and non-motor functions, and the cognitive dysmetria and dysmetria of thought models propose that abnormalities of the ...

Heterogeneity of trans-callosal structural connectivity and effects on resting state subnetwork integrity may underlie both wanted and unwanted effects of therapeutic corpus callostomy

open access: yesNeuroImage: Clinical, 2016
Background: The corpus callosum (CC) is the primary structure supporting interhemispheric connectivity in the brain. Partial or complete surgical callosotomy may be performed for the palliation of intractable epilepsy.

Human Cortical Serotonin 2A Receptor Occupancy by Psilocybin Measured Using [11C]MDL 100,907 Dynamic PET and a Resting-State fMRI-Based Brain Parcellation

open access: yesFrontiers in Neuroergonomics, 2022
Psilocybin (a serotonin 2A, or 5-HT2A, receptor agonist) has shown preliminary efficacy as a treatment for mood and substance use disorders. The current report utilized positron emission tomography (PET) with the selective 5-HT2A receptor inverse agonist

The structure of creative cognition in the human brain

open access: yesFrontiers in Human Neuroscience, 2013
Creativity is a vast construct, seemingly intractable to scientific inquiry – perhaps due to the vague concepts applied to the field of research. One attempt to limit the purview of creative cognition formulates the construct in terms of evolutionary ...

Default Bayes Factors for Model Selection in Regression

open access: yesMultivariate Behavioral Research, 2012
In this article, we present a Bayes factor solution for inference in multiple regression. Bayes factors are principled measures of the relative evidence from data for various models or positions, including models that embed null hypotheses. In this regard, they may be used to state positive evidence for a lack of an effect, which is not possible in ...

Portfolio selection with transaction costs and default risk [PDF]

open access: yesManagerial Finance, 2017
Purpose The purpose of this paper is to investigate the effect of default risk and transaction costs on the investor’s asset allocation and the liquidity premium. More precisely, it aims at answering the following question: can default risk generate a first-order effect on the investor’s asset allocation and a liquidity premium of the same order of ...

Default penalty as a selection mechanism among multiple equilibria [PDF]

open access: yesJournal of Behavioral and Experimental Finance, 2016
Closed exchange and production-and-exchange economies may have multiple equilibria, a fact that is usually ignored in macroeconomic models. Our basic argument is that default and bankruptcy laws are required to prevent strategic default, and these laws can also serve to provide the conditions for uniqueness.

Attention network dysfunction underlies memory impairment in posterior cortical atrophy

open access: yesNeuroImage: Clinical, 2019
Accumulating evidence suggests that memory is impaired in posterior cortical atrophy (PCA), alongside the early and defining visual disorder. The posterior parietal cortex is a key region of pathology in PCA and memory impairment may be the result of ...
