Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Purpose: To investigate the effect of TDCS application on different cortex regions on cognitive function.
Methods: Sixty individuals aged 18-30 were included in the study. The participants were randomly divided into the left dorsolateral prefrontal cortex (Left DLPFC Group)(n=20), the right posterior parietal cortex (Right PPC Group)(n=20), and the sham group (Sham Group)(n=20). tDCS was applied for 20 minutes on weekdays for 2 weeks. The participants were evaluated in terms of cognitive functions with Neuropsychometric Test Battery before and after treatment.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
LEFT DLPFC
The anode electrode of tDCS was applied to the left DLPFC and the cathode electrode was connected to the contralateral shoulder.
Transcranial Direct Current Stimulation
The intervention protocols were applied using tDCS (Teknofil TESsaNova). All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays. All applications were done in the form of 20-minute sessions.
RİGHT PPC
The anode electrode of tDCS was applied to the right PPC and the cathode electrode was connected to the contralateral shoulder.
Transcranial Direct Current Stimulation
The intervention protocols were applied using tDCS (Teknofil TESsaNova). All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays. All applications were done in the form of 20-minute sessions.
Sham
Placebo was applied by placing the electrodes in the right PPC and left DLPFC without applying current.
Transcranial Direct Current Stimulation
The intervention protocols were applied using tDCS (Teknofil TESsaNova). All individuals received 2 mA of anodal tDCS for 2 weeks on weekdays. All applications were done in the form of 20-minute sessions.
