Professor Jae-Jin Song's research lab specializes in neuroscience and neuroimaging, focusing on the neural mechanisms underlying tinnitus, Parkinson’s disease, neuropathic pain, and depression. The lab employs advanced neurophysiological techniques such as EEG, PET, and tDCS to investigate thalamocortical dysrhythmia and brain network dysfunction in these disorders. A central theme is identifying common and disorder-specific oscillatory and metabolic brain patterns to guide targeted neuromodulation therapies. The lab also emphasizes translational research, linking neuroimaging findings to clinical outcomes and personalized management strategies.

Thalamocortical dysrhythmia (TCD) is a model proposed to explain divergent neurological disorders. It is characterized by a common oscillatory pattern in which resting-state alpha activity is replaced by cross-frequency coupling of low- and high-frequency oscillations. We undertook a data-driven approach using support vector machine learning for analyzing resting-state electroencephalography oscillatory patterns in patients with Parkinson's disease, neuropathic pain, tinnitus, and depression. We
Although transcranial direct current stimulation (tDCS) has already been used to manage tinnitus patients, paucity of reports and variations in protocols preclude a comprehensive understanding. Hence, we conducted a meta-analysis based on systemic review to assess effectiveness of tDCS in tinnitus management and to compare stimulation parameters. PubMed was searched for tDCS studies in tinnitus. For randomized controlled trials (RCTs), a meta-analysis was performed. A total of 17 studies were id
This study proves that PET is a useful modality for tinnitus research and solidifies human tinnitus research itself by confirming previously described brain areas involved in the generation and maintenance of tinnitus.
These results may designate the role of the rostral ACC as the core of the descending noise cancellation system, and thus dysfunction of the rostral ACC may result in perception of tinnitus. The present study also opens a possibility of tinnitus modulation by neuromodulatory approaches targeting the rostral ACC.
Both groups demonstrated a significant improvement in DHI scores. However, the medication group showed significantly greater decrease in the functional (p = 0.018) and emotional (p = 0.030) subscale scores, as well as in the total DHI (p = 0.038) score.
PT resulting from either SSD or MFD-VS can be treated successfully with transmastoid resurfacing of the venous wall. Preoperative ipsilesional LFHL and the improvement of hearing threshold after surgical intervention may be preoperative and postoperative surrogate objective signatures of PT. To ensure the resolution of symptoms, secure reconstruction with firm materials and long-term follow-up are mandatory.
The present diagnostic approach may provide additional information regarding the origins of VPT cases as well as an efficient and objective diagnostic method. Furthermore, this approach may aid in the determination of appropriate imaging modalities, treatment planning, and evaluation of treatment outcomes.

Seven patients (0.7%) had an aberrant course or shape of the FN during CI. All these patients were pediatric. Four showed abnormal anterior or inferior location of the vertical segment, two had a bifurcated horizontal or vertical segment, and one had an inferiorly located horizontal segment. All seven patients displayed combined malformations of the cochlea and had malformed or missing ossicles. CIs were successfully performed via the facial recess approach and cochleostomy. There was no postope
