The convergence and divergence of episodic and semantic functions across lateral parietal cortex (2022)
Journal Article
Decades of research have highlighted the importance of lateral parietal cortex (LPC) across a myriad of cognitive domains. Yet, the underlying function of LPC remains unclear. Two domains that have emphasized LPC involvement are semantic memory and e... Read More about The convergence and divergence of episodic and semantic functions across lateral parietal cortex.
The immediate impact of transcranial magnetic stimulation on brain structure: Short-term neuroplasticity following one session of cTBS (2021)
Journal Article
Recent evidence demonstrates that activation-dependent neuroplasticity on a structural level can occur in a short time (2 hour or less) in the human brain. However, the exact time scale of structural plasticity in the human brain remains unclear. Usi...

Cognitive and Electrophysiological Correlates of Working Memory Impairments in Neurofibromatosis Type 1 (2021)
Journal Article
Neurofibromatosis 1 (NF1) is a single gene disorder associated with working Memory (WM) impairments. The aim of this study was to investigate P300 event-related potential (ERP) associated with WM in NF1. Sixteen adolescents with NF1 were compared wit...

Neural correlates of confusability in recognition of morphologically complex Korean words (2021)
Journal Article
When people confuse and reject a non-word that is created by switching two adjacent letters from an actual word, is called the transposition confusability effect (TCE). The TCE is known to occur at the very early stages of visual word recognition wit... Read More about Neural correlates of confusability in recognition of morphologically complex Korean words.
Enhancing vs. inhibiting semantic performance with transcranial magnetic stimulation over the anterior temporal lobe: frequency- and task-specific effects (2021)
Journal Article
Accumulating, converging evidence indicates that the anterior temporal lobe (ATL) appears to be the transmodal hub for semantic representation.
