Brief Summary:
This study will evaluate the influence of non-invasive brain stimulation on different elements of cognitive function in healthy persons between the ages of 18-90 years. It will specifically use transcranial direct current stimulation (tDCS) to evaluate the relationship between certain brain structures and cognitive abilities, like attention, working memory, visual search, etc.

Group/Cohort Intervention/treatment
Hemisphere Stimulation
Participants will receive 1mA vs. 2mA transcranial direct current stimulation of a) right and b) left brain structures (1x1 stimulation), and sham/placebo stimulation. A subset of participants will undergo right and left brain stimulation, but all will undergo sham stimulation.
 Device: Transcranial Direct Current Stimulation
Application of a weak electrical current to the scalp
Other Names:
  • Soterix DC Stimulator
  • Neuroconn DC Stimulator MR
Temporal Lobe Stimulation
A group of participants will undergo 1x1 transcranial direct current stimulation of the temporal lobes at 1 mA vs. 2 mA vs. sham stimulation. A second group of participants will undergo 1mA or 2mA stimulation, and sham, in right vs. left structures using 4x1 stimulation (e.g., 1mA left temporal, 1mA right temporal, sham; 2mA left temporal, 2mA right temporal, sham).
 Device: Transcranial Direct Current Stimulation
Application of a weak electrical current to the scalp
Other Names:
  • Soterix DC Stimulator
  • Neuroconn DC Stimulator MR
Frontal Lobe Stimulation
A group of participants will undergo 1x1 transcranial direct current stimulation of the frontal lobes at 1 mA vs. 2 mA vs. sham stimulation. A second group of participants will undergo 1mA or 2mA stimulation, and sham, in right vs. left frontal structures using 4x1 stimulation (e.g., 1mA left frontal, 1mA right frontal, sham; 2mA left frontal, 2mA right frontal, sham).
 Device: Transcranial Direct Current Stimulation
Application of a weak electrical current to the scalp
Other Names:
  • Soterix DC Stimulator
  • Neuroconn DC Stimulator MR
Parietal Lobe Stimulation
A group of participants will undergo 1x1 transcranial direct current stimulation of the parietal lobes at 1 mA vs. 2 mA vs. sham stimulation. A second group of participants will undergo 1mA or 2mA stimulation, and sham, in right vs. left parietal lobes using 4x1 stimulation (e.g., 1mA left parietal lobes, 1mA right parietal lobes, sham; 2mA parietal lobes, 2mA right parietal lobes, sham).
 Device: Transcranial Direct Current Stimulation
Application of a weak electrical current to the scalp
Other Names:
  • Soterix DC Stimulator
  • Neuroconn DC Stimulator MR
Supplementary Motor Stimulation
A group of participants will undergo 1x1 transcranial direct current stimulation of the Supplementary Motor Area at 1mA vs. 2mA vs. sham stimulation. A second group of participants will undergo 1mA or 2mA stimulation, and sham, in right vs. left Supplementary Motor Area using 4x1 stimulation (e.g., 1mA left Supplementary Motor Area, 1mA right Supplementary Motor Area, sham; 2mA left Supplementary Motor Area, 2mA right Supplementary Motor Area, sham).
 Device: Transcranial Direct Current Stimulation
Application of a weak electrical current to the scalp
Other Names:
  • Soterix DC Stimulator
  • Neuroconn DC Stimulator MR
Brain Structure Interactions Group
This cohort will evaluate the interaction between frontal, parietal, temporal, and SMA regions in cognitive function. To accomplish this goal will require evaluation of change in cognitive and neurocognitive performance following transcranial direct current stimulation of different brain regions within the same subjects. For example, we will evaluate the contribution of frontal, SMA, and parietal regions by asking participants to undergo stimulation sessions at each of these sites, in addition to a sham session.
