Increased activation product of complement 4 protein in plasma of individuals with schizophrenia
Structural variation in the complement 4 gene (C4) confers genetic risk for schizophrenia. The variation includes numbers of the increased C4A copy number, which predicts increased C4A mRNA expression. C4-anaphylatoxin (C4-ana) is a C4 protein fragment released upon C4 protein activation that has the potential

Examining subjective sleep quality in adults with hoarding disorder
Mahnke, A.*, Linkovski, O.*, Timpano, K., Sanchez, C., Varias, A., Filippou-Frye, M., Blasey, C., Bernert, R., & Rodriguez, C. I.
Published: Journal of Psychiatric Research, 2021.
Hoarding disorder (HD), characterized by difficulty parting with possessions and functionally impairing clutter, affects 2–6% of the population. Originally considered part of Obsessive-Compulsive Disorder (OCD), HD became a distinct diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. While sleep impacts OCD, little is known about sleep in HD. As HD patients often report poor sleep

Why Check? A meta-analysis of checking in Obsessive-Compulsive Disorder: Threat vs. Distrust of Senses
Strauss, Y. A., Fradkin, I., McNally, J. R., Linkovski, O., Anholt, G., Huppert D. J.
Published: Clinical Psychology Review, 2020
Compulsive checking is the most common ritual among individuals with obsessive-compulsive disorder (OCD). Yet, other than uncertainty, the variables prompting checking are not fully understood. Laboratory studies suggest that task conditions - whether threatening (anxiety-relevant) or neutral, and task type - whether requiring perceptual or reasoning decision-making – may be influential. The purpose of our...

Exploring BDNF Val66Met polymorphism and ketamine response in Obsessive-Compulsive Disorder: A preliminary study

Published: Journal of Clinical Psychopharmacology, 2019
Acommon single-nucleotide polymorphism (SNP) in the human brain derived neurotrophic factor (BDNF) gene (Val66Met; rs6265) has been reported to alter extinction learning in human carriers and knock-in mice with the SNP. Extinction learning is a major component of behavioral therapies for anxiety disorders...
Beyond uncertainty: a broader scope for incentive hope mechanisms and its implications
Linkovski, O., Weinbach, N., Edelman, S., Feldman M. W., Lotem, A., & Kolodny, O.
Published: Behavioral and Brain Sciences, 2019
We propose that food-related uncertainty is but one of multiple cues that predicts harsh conditions and may activate “incentive hope.” An evolutionarily adaptive response to these would have been to shift to a behavioral-metabolic phenotype geared toward facing hardship. In modernity, this phenotype may lead to pathologies such as obesity and hoarding. Our perspective suggests a novel therapeutic approach...

Mirror neurons in mirror-touch synesthesia
Linkovski, O., Katzin, N., Salti, M.
Published: The Neuroscientist, 2017
More than 20 years ago, a seminal article from Rizzolatti’s laboratory (di Pellegrino and others 1992) revealed a population of neurons in monkeys’ premotor regions that exhibited a similar pattern of activity when monkeys viewed an action and when they conducted the action. Rizzolatti named these neurons “mirror...
Training and transfer in aging – Is pathways overlap really necessary
Aisenberg, D., Cohen, Z., & Linkovski, O.
Published: Cognitive Neuroscience, 2017
The literature on aging shows clear effects of changes in white matter on cognitive performance, but these changes cannot solely account for behavioral differences seen in reaction-time tasks(Kennedy & Raz, 2009). The transfer effect of training in aging has been widely reviewed Many studies showed transfer effects to...

Inhibiting uncertainty: priming inhibition promotes reduction of uncertainty
Kalanthroff, E.,* Linkovski, O.,* Anholt, G., & Henik, A.
Published: Neuropsychologia, 2016
Uncertainty affects performance in many cognitive tasks, including the visual-search task, and individual differences in the experience of uncertainty may contribute to several psychological disorders. Despite the importance of uncertainty, to date, no study has explained the basic mechanisms underlying individual differences in the experience of uncertainty. However, it has been suggested that inhibition, a cognitive...
Stop checking: Repeated checking and its effects on response inhibition and doubt
Linkovski, O., Kalanthroff, E., Anholt, G., & Henik, A.
Published: Journal of Behavior Therapy and Experimental Psychiatry, 2016
Repeated checking is a common ritual in obsessive-compulsive disorder (OCD). van den Hout and Kindt (2003b) devised a task demonstrating paradoxical reductions in memory confidence following repeated checking. This effect was later found to be contingent upon response inhibition. The current study aims to...

What underlies the effect of sleep disruption? The role of alertness in obsessive- compulsive disorder (OCD)
Kalanthroff, E., Linkovski, O., Weinbach, N., Anholt, G., & Simpson, H. B.
Published: Journal of Behavior Therapy and Experimental Psychiatry, 2016
Several recent investigations report a correlation between shorter sleep duration and obsessive-compulsive disorder (OCD) symptoms. In a recent study, Nota, Schubert, and Coles (2016) investigated the potential underlying mechanism of this correlation and found that shorter sleep duration was associated with worse...
Musical space synesthesia: Automatic, explicit and conceptual connections between musical stimuli and space
Akiva-Kabiri, L.,* Linkovski, O.,* Gertner, L., & Henik, A.
Published: Consciousness and Cognition, 2014
In musical–space synesthesia, musical pitches are perceived as having a spatially defined array. Previous studies showed that symbolic inducers (e.g., numbers, months) can modulate response according to the inducer’s relative position on the synesthetic spatial form. In the current study we tested two musical–space..

Published: Journal of Behavior Therapy and Experimental Psychiatry, 2013
Obsessive-compulsive disorder (OCD) is an anxiety disorder characterized by compulsions aimed at reducing anxiety associated with intrusive cognitions. However, compulsive behaviors such as repeated checking were found to increase rather than decrease uncertainty related to obsessive thoughts...
Is it for real? Evaluating authenticity of musical pitch-space synesthesia
Linkovski, O., Akiva-Kabiri, L., Gertner, L., & Henik, A.
Published: Cognitive Processing, 2012
In spatial-sequence synesthesia, ordinal sequences are visualized in explicit spatial locations. We examined a recently documented subtype in which musical notes are represented in spatial configurations, to verify consistency and automaticity of musical pitch-space (M-S) synesthesia. An M-S synesthete performed...
