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

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

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.

From neural activity to behavioral engagement: temporal dynamics as their “common currency” during music

The human cortex is highly dynamic as manifest in its vast ongoing temporal repertoire. Similarly, behavior also variable over time with, for instance, fluctuating response times. How the brain's dynamics relates to of such emotions remains yet unclear, though. We measure median frequency (MF) a way (D-MF) investigate both EEG neural activity and subjects' continuous behavioral assessment their perceived emotional engagement changes during five different music pieces. Our main findings are: (i) significant differences dynamics, e.g., D-MF, ratings between pieces, (ii) the, pieces' EEG-based activity, (iii) there unidirectional relationship from pieces measured through correlation Granger causality respective D-MF's. Together, we demonstrate that shared fluctuations dynamics. This highlights key role connecting "common currency" (Northoff et al. 2020, 2024).

The Brain's Internal Echo: Longer timescales, stronger recurrent connections and higher neural excitation in self regions

NeuroImage, Год журнала: 2025, Номер unknown, С. 121221 - 121221

Understanding the brain's intrinsic architecture has long been a central focus of neuroscience, with recent advances shedding light on its topographic organization along uni and transmodal regions. How global uni-transmodal topography relates to psychological features like our sense self remains yet unclear, though. We here combine fMRI brain imaging computational modeling (Wilson Cowan model) better understand temporal, spatial physiological underlying distinction non-self regions within topography. resting state shows lower myelin content, longer timescales (measured by autocorrelation window/ACW), functional connectivity/synchronization signal correlation/GSCORR) in (based three-layer topography; Qin et al. 2020) compared Next, we fit data neural mass model, Wilson-Cowan which is enriched structural connectivity from human MRI/fMRI. first replicate empirical ACW GSCORR demonstrate that can, based same measures not only be distinguished but also unimodal themselves, respectively. Finally, model such differentiation two features: exhibit higher intra-regional excitatory recurrent connection levels their basal excitation than Our findings nature as well differences both connections The increased regions, together window, may ideally suited mediate self-referential processing: this can thus seen form 'psychological recurrence' where one input/stimulus processed prolonged echo-chamber way, is, an internal echo themselves.
