Modulating the Semantic System: The Role of Bilateral Anterior Temporal Lobes in Confrontation Naming- A Combined tDCS and Eye-Tracking Study

摘要: Modulating the Semantic System: The role of Bilateral Anterior Temporal Lobes in Confrontation NamingA Combined tDCS and Eye-Tracking Study Adviser: Professor Loraine K. Obler naming is a complex process that involves multiple stages can be initiated through modalities. Models confrontation have implicated areas such as anterior temporal lobe (ATL) temporo-parietal junction (TPJ) for semantic stage naming. Transcranial direct current stimulation (tDCS) was used to modulate neural excitability bilateral ATLs TPJs understand brain-behavior relationships involved Effects are often very small or non-existent when measured by reaction times accuracy. Therefore present study more sensitive eye-tracking measures (first fixation duration time) combination with measure effect tDCS. Twenty-four neurologically healthy native English speakers ranging ages 18-30 took part study. Participants named 120 pictures six-digit numbers both pre post three different sessions. Three sessions corresponded brain regions targeted; ATLs, Motor Cortex (MC) which served control site. Analysis behavioral data revealed application over increased first time but decreased latencies. results from thus confirm However, no evidence found. also provides further support efficacy suggests it viable tool investigating bases language/cognitive processes.
