Specific neuronal groups in the BNST related to anxiety and reward have been identified, but quantitative data about the information carried by local field potential (LFP) signals in this area during obsession\/compulsion are lacking. Here we investigate the BNST LFP in the schedule-induced polydipsia, an animal model of OCD. We implanted electrodes bilaterally in the BNST and random control brain regions in 32 male Wistar rats, and recorded corresponding LFP during compulsive and noncompulsive behavior. We first applied high-frequency (100 Hz) electrical stimulation through the implanted electrodes and analyzed its effects on compulsive behavior. We then performed time-frequency analysis of LFPs and statistically compared the normalized power of \u03b4 (1\u20134 Hz), \u03b8 (4\u20138 Hz), \u03b1 (8\u201312 Hz), \u03b2 (12\u201330 Hz), and lower \u03b3 (30\u201345 Hz) bands between different groups. Our data showed that the normalized \u03b4, \u03b2, and \u03b3 powers in the right BNST were specifically correlated with compulsive behaviors. \u03b4 and \u03b3 oscillations increased and decreased during the initiation phase of compulsion, respectively, whereas \u03b2 increased after compulsion stopped. Moreover, the effect of BNST electrical stimulation, in terms of suppression of compulsion, was significantly correlated with the percentage change of these bands during compulsion. Our research reveals potential biomarkers and underlying neurophysiological mechanisms of compulsion and warrants further assessment of the use of LFP for closed-loop neuromodulation in OCD.<\/jats:p><jats:p><jats:bold>SIGNIFICANCE STATEMENT<\/jats:bold>Although specific neuronal groups in the bed nucleus of the stria terminalis (BNST) related to anxiety and reward circuitries have been identified, psychopathological information carried by local field potentials in the BNST has not yet been described. We discovered that normalized powers of the right BNST \u03b4, \u03b2, and \u03b3 oscillations were highly correlated with compulsion. Specifically, \u03b4 and \u03b3 oscillations increased and decreased during the initiation phase of compulsion, respectively, whereas \u03b2 increased after compulsion stopped. Such correlations were not found in other parts of the brain during compulsion, or in the BNST during noncompulsive behavior. Current findings reveal real-time neurophysiological biomarkers of compulsion and warrant further assessment of the use of local field potentials for closed-loop neuromodulation for OCD.<\/jats:p>","DOI":"10.1523\/jneurosci.1872-15.2016","type":"journal-article","created":{"date-parts":[[2016,9,28]],"date-time":"2016-09-28T16:02:23Z","timestamp":1475078543000},"page":"10050-10059","source":"Crossref","is-referenced-by-count":14,"title":["Field
