La estimulación cerebral transcraneal directa (tDCS) y de la estimulación cerebral transcraneal por corriente alterna (tACS), así como de los efectos que tienen en el cerebro. Estas son técnicas que involucran la aplicación de corriente eléctrica de bajo nivel en el cuero cabelludo con el propósito de modular la actividad cerebral. Aquí hay una breve descripción de cada una:
- tDCS (Estimulación Cerebral Transcraneal Directa): En tDCS, se aplican corrientes eléctricas débiles a través de electrodos colocados en el cuero cabelludo. Uno de los electrodos es el «ánodo» y el otro el «cátodo». Se cree que el tDCS puede aumentar o disminuir la excitabilidad neuronal en la región bajo el ánodo, dependiendo de la polaridad utilizada. Aunque los efectos no suelen ser tan inmediatos o intensos como con otros métodos de estimulación cerebral, se ha investigado su uso en una variedad de aplicaciones, como mejorar el rendimiento cognitivo, tratar la depresión o el dolor crónico, y ayudar en la rehabilitación neurológica.
- tACS (Estimulación Cerebral Transcraneal por Corriente Alterna): En tACS, se aplica una corriente eléctrica alterna en el cuero cabelludo a una frecuencia específica. Esta técnica busca sincronizar o desincronizar las oscilaciones eléctricas en el cerebro, lo que puede tener efectos en la función cerebral. Se ha investigado para mejorar la memoria, el aprendizaje y tratar trastornos neuropsiquiátricos, entre otras aplicaciones.
Ambas técnicas han sido objeto de investigación en las áreas de neurociencia y neurorehabilitación, y se están explorando en ensayos clínicos para diversas aplicaciones terapéuticas. Sin embargo, es importante destacar que la tDCS y la tACS no están exentas de controversia y debate en términos de su eficacia y seguridad. Los resultados de los estudios pueden variar y no siempre son concluyentes. Además, su uso debe ser supervisado por profesionales de la salud y realizarse con precaución, ya que la estimulación cerebral puede tener efectos impredecibles y no deseados si se aplica incorrectamente.

«In mindfulness, one of the most popular types of meditation practiced in western cultures today, your attention is focused on the present moment with an attitude of curiosity, openness, and acceptance. Neuroimaging studies show that regular practice can increase the volume of several key areas of the brain, including the right insula. This region is involved in interoception, the perception of your body and how you’re physically feeling. Meditation also decreases activity in the default mode network, a system of connected brain regions that turns on when our minds start to wander and is involved in thinking about ourselves and our relationships. Research suggests that high activity in this network is linked to feelings of unhappiness. By turning down activity in the default mode network while turning up activity in the insula, mindfulness meditation may help you stop obsessing so much about yours and others’ perception of you and start being more present in the moment. In other words, stop listening to your brain and start listening to your body.»
Badran and his partner at Bodhi NeuroTech, Baron Short, an associate professor of psychiatry at the Medical University of South Carolina, think that tDCS can help speed up these positive changes. In their first study, published last year, they led novice meditators through a 20-minute guided mindfulness meditation session while increasing electrical activity in the right insula and turning down activity in the default mode network. To do so, they placed the positive electrode over the right temple, which sits above the insula, and the negative electrode over the left eyebrow to target the medial prefrontal cortex, which is part of the network. Participants reported feeling significantly higher levels of “acting with awareness” after meditating with tDCS compared with meditating without it, but other changes in mood were not significant.

Notes on youtube video: Efficacy and Safety of Transcranial Direct Current Stimulation: For treating OCD patients.
Minute: 4:46. Cathodal stimulation over the pre-SMA with an extra-cephalic anode more likely to activate structures involved in OCD circuits (anterior cingulate cortex and anterior basal ganglia).
Cathode: supplementary motor cortex.
Anode: left deltoid (neutral region).
2 mA current on surface of 25cm2 (3.87 in2).
Sham group: device turned off after 30 seconds of active stimulation.
Minuto 7: 22% de mejora en los síntomas de TOC.
Minute 8: In this sample of patients with severe, treatment-resistant OCD with multiple comorbidities, active tDCS was superior to sham stimulation in reducing OCD symptoms.
The reduction in depression and anxiety symptoms was also greater in the active tDCS than in the sham group, but differences were nonsignificant.
Minute 9: Gowda et al., 2018: RCT. Anodal tDCS over the pre-SMA and the cathode over the right supra-orbital area associated with improvement; shorter duration (2 daily sessions for 5 days), samaller sample.

Why Brain Stimulation?
Brain stimulation makes your brain function differently.
tDCS is the most studied mode of brain stimulation.
Stimulation is a relatively new field that is still being explored.
There is a mixture of excitement and caution:

Dr. Clark is the Founding Director of the Psychology Clinical Neuroscience Center at UNM (http://psych.unm.edu), where he and his associates investigate the relationship between mind and brain and are developing new methods of combined brain stimulation and imaging to accelerate learning and treat illness. Dr. Clark’s ultimate goals are to combine brain stimulation with neuroimaging to broaden our understanding of the human brain and cognition, to develop innovations in learning and education, and to develop new treatments based on neuromodulation to reduce the suffering caused by psychiatric and neurological disorders. He employs structural and functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), event-related potentials (ERPs) and methods of transcranial brain stimulation, including transcranial electrical stimulation (TES) including tDCS, tRNS and tACS, transcranial ultrasound stimulation (TUS), transcranial photobiomodulation (tPBM), as well as other methods to examine human brain structure and function. Using these tools, he is investigating the basic organizational principles of perception, learning, memory, sleep, attention and language in healthy people. He also uses these methods to examine the neural basis of clinical disorders, such as drug use and addiction, psychotic disorders including schizophrenia and forms of dementia including Alzheimer’s disease, among others. His recent area of research examines how brain stimulation can be used to increase learning and performance in healthy subjects, and the mechanisms by which these methods produce changes in brain function and behavior.

tACS: Transcranial Alternating Current Stimulation (tACS) is a device that applies a low-intensity sinusoidal electrical current to the brain through electrodes on the scalp. The technique can be painless and is thought to boost the brain’s own oscillations, which can be used to treat disease or enhance brain function. In many ways tACS is similar to tDCS as a neuromodulatory technique, but instead of applying a direct electrical current, tACS oscillates a sinusoidal current at a chosen frequency to interact with the brain’s natural cortical oscillations.
«All forms of macroscopic energy may be able to change nervous system function and human behavior when applied the right way, each has shown some ability to change behavior. Each method will have advantages and disadvantagse depending on the anatomical targets and specific behavioral applications.»
tRNS (Transcranial random noise stimulation) a wide range of frequencies is needed for increasing cortical excitability). ranscranial random noise stimulation (tRNS) is a recent neuromodulation protocol. The high-frequency band (hf-tRNS) has shown to be the most effective in enhancing neural excitability. The frequency band of hf-tRNS typically spans from 100 to 640 Hz. Here we asked whether both the lower and the higher half of the high-frequency band are needed for increasing neural excitability. Three frequency ranges (100–400 Hz, 400–700 Hz, 100–700 Hz) and Sham conditions were delivered for 10 minutes at an intensity of 1.5 mA over the primary motor cortex (M1).
