Abstract Deep brain stimulation (DBS) of the subcallosal cingulate (SCC) can provide long-term symptom relief for treatment-resistant depression (TRD) 1 . However, achieving stable recovery is unpredictable 2 , typically requiring trial-and-error adjustments due to individual trajectories and subjective reporting 3 We currently lack objective brain-based biomarkers guide clinical decisions by distinguishing natural transient mood fluctuations from situations intervention. To address this gap, we used a new device enabling electrophysiology recording deliver SCC DBS ten TRD participants (ClinicalTrials.gov identifier NCT01984710).

Predictive neuromodulation of cingulo-frontal neural dynamics in major depressive disorder using a brain-computer interface system: A simulation study

Frontiers in Computational Neuroscience, Journal Year: 2023, Volume and Issue: 17

Published: March 6, 2023

Deep brain stimulation (DBS) is a promising therapy for treatment-resistant major depressive disorder (MDD). MDD involves the dysfunction of network that can exhibit complex nonlinear neural dynamics in multiple frequency bands. However, current open-loop and responsive DBS methods cannot track multiband MDD, leading to imprecise regulation symptoms, variable treatment effects among patients, high battery power consumption.Here, we develop closed-loop brain-computer interface (BCI) system predictive neuromodulation treating MDD. We first use biophysically plausible ventral anterior cingulate cortex (vACC)-dorsolateral prefrontal (dlPFC) mass model simulate response DBS. then offline identification build dynamic predicts effect on activity. next identified design an online BCI neuromodulation. The consists state estimator controller. estimates from history activity previously delivered patterns. controller takes estimated as feedback signal optimally adjusts regulate therapeutic targets. vACC-dlPFC simulation testbed test compare it with state-of-the-art treatments MDD.We demonstrate our accurately Consequently, regulates resulting significantly smaller control errors lower consumption than DBS.Our results have implications developing future precisely-tailored clinical
