Improved Attention

Anode: Supraorbital (FP1) or (FP2)     Cathode: Opposite Shoulder

 

– OR –

Study Results: Improving Attention 

Other Uses: Working Memory Improvement, Complex memory span and ADHD 

Notes: Some individuals have shown an increase in selective attention. Selective attention and memory appears to be improved through the use of this montage

Studies:

Enhancement of selective attention by tDCS: Interaction with interference in a Sternberg task(Thomas E. Gladwina, Tess E. den Uyla, Felipe F. Fregnib, Reinout W. Wiersa)
Modulating behavioral inhibition by tDCS combined with cognitive training(Thomas Ditye, Liron Jacobson, Vincent Walsh, Michal Lavidor)

Improving Insight

tDCS Montage Placement: Improving Insight

Anode: Right Temporal (T4)

Cathode: Left Temporal (T3)

tDCS Electrode Placement - Insight Improvement - Anode-T4 Cathode-CT3 anatomical head   

Studies Show: Insight Improvement 

Other Uses: Savant Learning, Problem Solving, General Cognitive Enhancement 

Notes: It is believed that improvement in insight is obtained through decreasing cortical excitability in the left hemisphere, and increasing cortical excitability in the right hemisphere.

Studies: Chi, Snyder (2011)Chi, Snyder (2012)

Increased Present Awareness

Anode: Right Mastoid (P10)     Cathode: Right DLPFC (F4)

tDCS Placements - Increased Present Awareness - P10_F4

Study Results: Increased Present Awareness 

Other Uses: Increased Impulsiveness 

Notes: External modulation of both the left and right DLPFC has been shown to influence driving behavior with Anodal stimulation of the DLPFC resulting in a more careful driving style.  

Study:

Emotion: Systems, Cells, Synaptic Plasticity (Michael T Rogan, Joseph E LeDoux)

Improved Motor Skills and Learning

Anode: Ipsilesional [C3)     Cathode: Contralesional (C4)

(graphic coming shortly)

Study Results: Improved Motor Recovery in Stroke 

Other Uses: Improved Motor Skills, Enhance Motor learning 

Notes: The improvement of motor function was significantly greater in the real stimulation group, when compared to the sham group.  

Studies:

Improved Mathematical Abilities

tDCS Montage Placement: Improved Mathematical Abilities

Anode: Right Parietal (P4)

Cathode: Left Parietal (P3)

 tDCS Electrode Placement Increased Mathematical Abilities - P4_P3 - LEFT Electrode Placements Increased Mathematical Abilities - P4_P3 - RIGHT

Study Results:
Enhanced Numerical & Mathematic Abilities
Notes:
Studies have shown that stimulation of the parietal cortex can enhance mathematic ability for up to 6 months following repeated stimulation sessions. Most affected was material which was learned recently.

Reducing Cravings and Addicting Behaviors

Anode: Right DLPFC (F4)     Cathode: Left DLPFC (F3)

tDCS Electrode Placement - Reduced Risk Taking - F3-F4 FRONT

Study Results: Reduced cigarette cravings and other addicting behaviors 

Other Uses: Reduced alcohol and Junk food cravings. Studies focusing on this montage have shown the potential for decreased risk-taking in humans.

Studies:
Cumulative priming effects of cortical stimulation on smoking cue-induced craving
A randomized controlled trial of targeted prefrontal cortex modulation with tDCS in patients with alcohol dependence

Reducing Risk Taking

Anode: Right DLPFC (F4)     Cathode: Left DLPFC (F3)

tDCS Electrode Placement - Reduced Risk Taking - F3-F4 FRONT

Study Results: Reduced Risk Taking 

Other uses: Reduced overeating, alcohol & drug addiction, gambling addiction 

Notes: Activation of prefrontal cortex by transcranial direct current stimulation reduces appetite for risk during ambiguous decision making. 

Studies: Fecteau, Fregni (2007)Fecteau, Pascual-Leone (2007)

Alternative Depression Treatment

Anode: Left Supraorbital (FP1)

Cathode: Top of Head (CZ), Occipital (OZ)

tDCS Montage - Depression Treatment Fp1-OzCz     tDCS Electrode Montage - Depression Treatment Fp1-OzCz

Study Results: Depression Treatment

Other Uses: Improved Mood

Notes: While the majority of depression related tDCS studies utilize the more popular F3 – FP2 electrode placement, this alternative placement has shown antidepressant potential in certain patients suffering from depression and other related mood disorders.

Study: D. Martin, C. Loo (2014)

Accelerated Learning (DARPA Montage)

Anode: Right Temple [F10)     Cathode: Left Shoulder

tDCS DARPA Montage Electrode Positioning F10-Left_Shoulder

Study Results: Accelerated Learning (DARPA Montage) 

Other Uses: New Skill Acquisition, Increased Focus, Accelerated Learning 

Notes: The US Military has showed that tDCS can increase focus and learning speeds by up to 2x the average. Academic settings have replicated these studies with the same results, doubling learning speeds in students. The vast evidence supports the notion that tDCS can accelerate learning and enhance performance in a range of complex cognitive tasks.
