Mechanisms of Action in tDCS

The precise mechanisms through which tDCS exerts its effects are still under investigation. However, several mechanisms have been proposed to explain its influence on brain function:

Modulation of Resting Membrane Potential

tDCS modulates the resting membrane potential of neurons, making them more or less likely to fire action potentials. Anodal stimulation is believed to increase the excitability of neurons by depolarizing the resting membrane potential, while cathodal stimulation decreases excitability by hyperpolarizing the resting membrane potential.

Changes in Neurotransmitter Release

tDCS may influence the release and uptake of neurotransmitters in the stimulated brain regions. It has been suggested that tDCS can alter the balance of excitatory and inhibitory neurotransmitters, leading to changes in synaptic activity and neural communication.

Long-Term Potentiation and Depression

tDCS has been linked to the induction of long-term potentiation (LTP) and long-term depression (LTD), which are processes associated with synaptic plasticity. LTP strengthens synaptic connections, while LTD weakens them. Modulating these processes through tDCS may facilitate learning, memory formation, and cognitive enhancement.

Neurovascular Changes

tDCS can influence cerebral blood flow and oxygenation levels in the stimulated brain regions. These neurovascular changes may contribute to the observed effects of tDCS on cognitive function and performance.

Network Effects

The effects of tDCS extend beyond the stimulated brain region, impacting the connectivity and functional integration of neural networks. tDCS-induced changes in neural activity can propagate to distant brain areas, influencing their function and interaction within broader networks.
