Ventral striatum temporal interference brain stimulation enhances the reward-positivity event-related potential and reduces anxiety.

Neuroimage July 1, 2026 Jonathan S Ryan, Timothy J Mcdermott, Boris Botzanowski et al.

Temporal interference (TI) electrical stimulation is a novel neuromodulation method that can target deep brain structures to enhance the impact of behavioral techniques. We tested the feasibility of TI targeting the ventral striatum (VS) during an emotion regulation practice (breath-focused mindfulness meditation). To assess target engagement, we used electroencephalography (EEG) to measure...

Ventral striatum temporal interference brain stimulation enhances the reward positivity event-related potential and reduces anxiety.

Research Square February 9, 2026 Jonathan S Ryan, Timothy J Mcdermott, Boris Botzanowski et al.

Temporal interference (TI) electrical stimulation is a novel neuromodulation method that can target deep brain structures to enhance the impact of behavioral techniques. We tested the feasibility of TI in targeting the ventral striatum (VS) in concert with an emotion regulation practice (breath-focused mindfulness meditation). As an assay of target engagement, we used electroencephalography...

Good vibrations: Sternal vibration enhances white matter density and interoceptive awareness.

Research Square December 22, 2025 Negar Fani, Alexa Kondas, Vishwadeep Ahluwalia et al.

Vibration-based therapies are understudied but promising methods for alleviating psychiatric symptoms, particularly when paired with behavioral practices. The potential neuroplastic changes associated with a novel neurostimulation method, sternal vibration, and associations with clinical change remain unknown. We examined effects of sternal vibration paired with mindfulness meditation on change...

Find your rhythm and regulate: Breath-synced vibration feedback during breath-focused mindfulness reduces respiration variability in trauma-exposed adults.

Journal of Anxiety Disorders June 1, 2025 Timothy J Mcdermott, Greg J Siegle, Alfonsina Guelfo et al. 2 citations

Stress and anxiety are associated with increased autonomic arousal, including altered respiration. Breath-focused mindfulness meditation can reduce stress and anxiety, but trauma-exposed adults with dissociation have difficulty engaging in this practice. Our ongoing clinical trial examines if vibration-augmented breath-focused mindfulness (VABF) can improve outcomes and increase engagement....

ENIGMA-Meditation: Worldwide Consortium for Neuroscientific Investigations of Meditation Practices.

Biological psychiatry. Cognitive neuroscience and neuroimaging April 1, 2025 Saampras Ganesan, Fernando A Barrios, Ishaan Batta et al. 6 citations

Meditation is a family of ancient and contemporary contemplative mind-body practices that can modulate psychological processes, awareness, and mental states. Over the last 40 years, clinical science has manualized meditation practices and designed various meditation interventions that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past...

Self-regulation of the posterior cingulate cortex with real-time fMRI neurofeedback augmented mindfulness training in healthy adolescents: A nonrandomized feasibility study

Cognitive Affective & Behavioral Neuroscience March 15, 2022 Namik Kirlic, Zsofia P Cohen, Aki Tsuchiyagaito et al. 29 citations

Mindfulness training (MT) promotes the development of one's ability to observe and attend to internal and external experiences with objectivity and nonjudgment with evidence to improve psychological well-being. Real-time functional MRI neurofeedback (rtfMRI-nf) is a noninvasive method of modulating activity of a brain region or circuit. The posterior cingulate cortex (PCC) has been hypothesized...
