Infinite singletons and the default mode network

Journal of Psychology & Clinical Psychiatry May 9, 2022 Giulia Battilotti, Miloš Borozan, Rosapia Lauro Grotto

In the present contribution we sketch an interpretation of the characterizing aspects of processing taking place in the Default Mode Network based on a formal logic model of the psychoanalytic theory. In particular, we apply a logical model of the structural Freudian Unconscious as described in the so-called Bi-Logic introduced by the Chilean psychoanalyst I. Matte Blanco. We ground our...

Default mode network components and its relationship with anomalous self-experiences in schizophrenia: A rs-fMRI exploratory study.

Psychiatry Research Neuroimaging May 1, 2022 Alejandro Roig-Herrero, Álvaro Planchuelo-Gómez, Marta Hernández-garcía et al.

Anomalous self-experiences (ASEs) in schizophrenia have been under research for the last 20 years. However, no neuroimage studies have provided insight of the possible biological underpinning of ASEs. In this novel approach, the connectivity within the default mode network, calculated through a ROI-based analysis of functional magnetic resonance imaging data, was correlated to the ASEs scores...

Subcortical control of the default mode network: Role of the basal forebrain and implications for neuropsychiatric disorders

Brain Research Bulletin May 1, 2022 David D. Aguilar, J. McNally

The precise interplay between large-scale functional neural systems throughout the brain is essential for performance of cognitive processes. In this review we focus on the default mode network (DMN), one such functional network that is active during periods of quiet wakefulness and believed to be involved in introspection and planning. Abnormalities in DMN functional connectivity and...

Mindfulness-Enhanced Computerized Cognitive Training for Depression: An Integrative Review and Proposed Model Targeting the Cognitive Control and Default-Mode Networks

Brain Science May 1, 2022 Mikell Bursky, Dakota A. Egglefield, Sophie Schiff et al.

Depression is often associated with co-occurring neurocognitive deficits in executive function (EF), processing speed (PS) and emotion regulation (ER), which impact treatment response. Cognitive training targeting these capacities results in improved cognitive function and mood, demonstrating the relationship between cognition and affect, and shedding light on novel targets for...

Involvement of the default mode network under varying levels of cognitive effort

Scientific Reports April 15, 2022 S. Weber, André Aleman, Kenneth Hugdahl

Everyday cognitive functioning is characterized by constant alternations between different modes of information processing, driven by constant fluctuations in environmental demands. At the neural level, this is realized through corresponding dynamic shifts in functional activation and network connectivity. A distinction is often made between resting and task processing and between task-negative...

Changes in the Intranetwork and Internetwork Connectivity of the Default Mode Network and Olfactory Network in Patients with COVID-19 and Olfactory Dysfunction

Brain Science April 1, 2022 Hui Zhang, T. Chung, Fergus Kai-Chuen Wong et al.

Olfactory dysfunction (OD) is a common symptom in coronavirus disease 2019 (COVID-19) patients. Moreover, many neurological manifestations have been reported in these patients, suggesting central nervous system involvement. The default mode network (DMN) is closely associated with olfactory processing. In this study, we investigated the internetwork and intranetwork connectivity of the DMN and...

Chemogenetic stimulation of tonic locus coeruleus activity strengthens the default mode network

Science Advances April 1, 2022 E. Oyarzabal, Li-Ming Hsu, Manasmita Das et al.

The default mode network (DMN) of the brain is functionally associated with a wide range of behaviors. In this study, we used functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and spectral fiber photometry to investigate the selective neuromodulatory effect of norepinephrine (NE)–releasing noradrenergic neurons in the locus coeruleus (LC) on the mouse DMN....

Tasks activating the default mode network map multiple functional systems

Brain Structure and Function February 18, 2022 Lorenzo Mancuso, Sara Cavuoti-Cabanillas, Donato Liloia et al.

Recent developments in network neuroscience suggest reconsidering what we thought we knew about the default mode network (DMN). Although this network has always been seen as unitary and associated with the resting state, a new deconstructive line of research is pointing out that the DMN could be divided into multiple subsystems supporting different functions. By now, it is well known that the...

Interplay Between the Salience and the Default Mode Network in a Social-Cognitive Task Toward a Close Other

Frontiers in Psychiatry February 7, 2022 Cátia Ribeiro da Costa, Jose M. Soares, Patrícia Oliveira-Silva et al.

Social cognition relies on two main subsystems to construct the understanding of others, which are sustained by different social brain networks. One of these social networks is the default mode network (DMN) associated with the socio-cognitive subsystem (i.e., mentalizing), and the other is the salience network (SN) associated with the socio-affective route (i.e., empathy). The DMN and the SN...

Default Mode Network and Neural Phase Synchronization in Healthy Aging: A Resting State EEG Study

Neuroscience January 17, 2022 Ricky Chow, Rahel Rabi, Shahier Paracha et al. 23 citations

Aging is associated with altered brain connectivity within the default mode network (DMN). Although research using functional magnetic resonance imaging has quantified age-related alterations in functional connectivity within this network during resting state, it is less clear how this may be reflected in electrophysiological measures, and how this relates to cognitive performance in older...
