Shorter and inflexible intrinsic neural timescales of the self in schizophrenia

Journal of Psychiatry and Neuroscience, Год журнала: 2025, Номер 50(1), С. E57 - E66

Опубликована: Янв. 23, 2025

Background:

Schizophrenia is hypothesized to involve a disturbance in the temporal dynamics of self-processing, specifically within interoceptive, exteroceptive, and cognitive layers self. This study aimed investigate intrinsic neural timescales (INTs) these self-processing among people with schizophrenia.

Methods:

We conducted functional magnetic resonance imaging (fMRI) INTs, as measured by autocorrelation window, schizophrenia healthy controls during both resting-state task (memory encoding retrieval) conditions. obtained data from UCLA Consortium for Neuropsychiatric Phenomics set preprocessed using fMRIPrep.

Results:

included 45 65 controls. Compared controls, participants exhibited significantly shorter INTs across all 3 rest (p < 0.05). In addition, those showed less INT shortening states, leading reduced rest–task differences observed similar patterns shortened primary sensory motor regions.

Limitations

taking medication, which may influence INTs; our was also limited relatively slow resolution fMRI higher variability function group, compared control group.

Conclusion:

Our findings suggest that characterized global self, manifesting inflexible sensorimotor These results support hypothesis involves fundamental disruption integration signals, contributing core self-disturbance disorder.

Bridging the gap of brain and experience – Converging Neurophenomenology with Spatiotemporal Neuroscience

Neuroscience & Biobehavioral Reviews, Год журнала: 2025, Номер unknown, С. 106139 - 106139

Опубликована: Апрель 1, 2025

Neuroscience faces the challenge of connecting brain and mind, with mind manifesting in first-person experience while brain's neural activity can only be investigated third-person perspective. To connect mental states, neurophenomenology provides a methodological tool kit for systematically linking subjective objective observations activity. However, beyond providing systematic strategy ('disciplined circularity'), it leaves open how are related among themselves, independent our strategy. The recently introduced Spatiotemporal suggests that share commonly underlying feature as their "common currency", notably analogous spatiotemporal dynamics. Can inform to allow deeper more substantiative connection activity? goal paper is show Neurophenomenology converged integrated each other gain better understanding brain-mind connection. We describe convergence on theoretical grounds which, subsequently, illustrated by empirical examples like self, meditation, depression. In conclusion, we propose integration provide complementary insights, enrich both fields, allows connection, opens door developing novel approaches investigation.

In Between the Psychological and Physiological Self - The Impact of Covid-19 Pandemic on the Neuro-Socio-Ecological and Inflammatory Mind-Body-Brain System.

The COVID-19 pandemic has had a profound impact on individuals' sense of self perturbating the connectedness with others, touching upon deep existential fears and intersubjective cultural layers, emphasizing importance neuro-socio-ecological alignment for security psychological self. We can still observe after years how social distancing measures, quarantines, lockdowns have disrupted connections routines, leading to feelings isolation, anxiety depressive symptomatology. Furthermore, from physiological perspective, some people continue experience health problems long having COVID-19, these ongoing are sometimes called post-COVID-19 syndrome or post-COVID conditions (PASC). In this complex scenario, through operationalization its baseline, our aim is try shed new light elements resilience vs. vulnerability. Here we intend baseline as crossroads between psychology physiology show pandemic, especially in (PACS), left traces mind-body-brain system at inflammatory level.

Neural representations of statistical and rule‐based predictions in Gilles de la Tourette syndrome

Human Brain Mapping, Год журнала: 2024, Номер 45(8)

Опубликована: Июнь 1, 2024

Gilles de la Tourette syndrome (GTS) is a disorder characterised by motor and vocal tics, which may represent habitual actions as result of enhanced learning associations between stimuli responses (S-R). In this study, we investigated how adults with GTS healthy controls (HC) learn two types regularities in sequence: statistics (non-adjacent probabilities) rules (predefined order). Participants completed visuomotor sequence task while EEG was recorded. To understand the neurophysiological underpinnings these GTS, multivariate pattern analyses on temporally decomposed signal well sLORETA source localisation method were conducted. We found that people showed superior statistical but comparable rule-based compared to HC participants. Adults had different neural representations for both than adults; specifically, maintained regularity longer more overlap them HCs. Moreover, over time scales, distinct fronto-parietal structures contribute groups. propose hyper-learning consequence altered sensitivity encode complex statistics, might lead actions.
