آیا باید برای tDCS همانند TMS شدت تحریک برای هر فرد تنظیم شود؟!
Efficacy of Anodal Transcranial Direct Current Stimulation is Related to Sensitivity to Transcranial Magnetic Stimulation
https://telegram.me/farmed/88
Highlights
•Substantial inter-individual variability is observed in tDCS studies.
•tDCS experiments use a fixed stimulation level, ignoring individual differences in sensitivity to brain stimulation.
•TMS thresholds were used as proxy of sensitivity to brain stimulation, and then related to efficacy of tDCS.
•Following anodal tDCS, changes in TMS-induced motor evoked potentials were measured.
•Efficacy of anodal tDCS was predicted by individual differences in sensitivity to brain stimulation (TMS thresholds).

Cognitive and neurophysiological markers of ADHD persistence and remission
The British Journal of Psychiatry Aug 2015
Results
ADHD persisters differed from remitters on preparation-vigilance measures (contingent negative variation, delta activity, reaction time variability and omission errors), IQ and actigraph count, but not on executive control measures of inhibition or working memory (nogo-P3 amplitudes, commission errors and digit span backwards).

در سال های اخیر انواع مختلفی از نوروفیدبک معرفی شده اند که می‌توان به 7 نوع زیر دسته بندی نمود:
1- The most frequently used neurofeedback is frequency/power neurofeedback. This technique typically includes the use of 2 to 4 surface electrodes, sometimes called “surface neurofeedback”. It is used to change the amplitude or speed of specific brain waves in particular brain locations to treat ADHD, anxiety, and insomnia.

2- Slow cortical potential neurofeedback (SCP-NF) improves the direction of slow cortical potentials to treat ADHD, epilepsy, and migraines (Christiansen, Reh, Schmidt, & Rief, 2014).

3- Low-energy neurofeedback system (LENS) delivers a weak electromagnetic signal to change the patient’s brain waves while they are motionless with their eyes closed (Zandi-Mehran, Firoozabadi, & Rostami, 2014). This type of neurofeedback has been used to treat traumatic brain injury, ADHD, insomnia, fibromyalgia, restless legs syndrome, anxiety, depression, and anger.

4- Hemoencephalographic (HEG) neurofeedback provides feedback on cerebral blood flow to treat migraine (Dias, Van Deusen, Oda, & Bonfim, 2012).

5- Live Z-score neurofeedback is used to treat insomnia. It introduces the continuous comparison of variables of brain electrical activity to a systematic database to provide continuous feedback (Collura, Guan, Tarrant, Bailey, & Starr, 2010).

6- Low-resolution electromagnetic tomography (LORE-TA) involves the use of 19 electrodes to monitor phase, power, and coherence (Pascual-Marqui, Michel, & Lehmann, 1994). This neurofeedback technique is used to treat addictions, depression, and obsessive-compulsive disorder.

7- Functional magnetic resonance imaging (fMRI) is the most recent type of neurofeedback to regulate brain activity based on the activity feedback from deep subcortical areas of the brain (Hurt, Arnold, & Lofthouse, 2014; Lévesque, Beauregard, & Mensour, 2006a).
