Summary
Noninvasive brain stimulation, specifically repetitive transcranial magnetic stimulation (rTMS), offers a promising therapeutic approach for substance use disorders (SUDs). This technique modulates neural circuits involved in addiction through neuroplasticity, showing effectiveness in both preclinical and clinical studies.
Area of Science:
- Neuroscience
- Psychiatry
- Neuromodulation
Background:
- Addiction is a complex brain disorder involving maladaptive neural circuitry.
- Noninvasive brain stimulation (NIBS) techniques are emerging as potential treatments for addiction.
- Transcranial magnetic stimulation (TMS) has shown promise in preclinical and clinical studies for substance use disorders (SUDs).
Purpose of the Study:
- To provide an integrated view of TMS mechanisms in modulating addiction-related brain circuitry.
- To review evidence on the efficacy of repetitive TMS (rTMS) for treating SUDs.
Main Methods:
- Review of preclinical and clinical studies on TMS for SUDs.
- Analysis of TMS-induced neuroplasticity mechanisms at local and network levels.
Main Results:
- Repetitive TMS induces short- and long-term effects on neural activity.
- TMS modulates maladaptive brain circuitry implicated in addiction.
- Evidence suggests rTMS is an effective interventional tool for SUD treatment.
Conclusions:
- TMS is a safe and cost-effective therapeutic option for SUDs.
- Understanding TMS mechanisms enhances its application in addiction treatment.
- rTMS holds significant potential for the future of addiction therapy.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
1.2K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.
Input signals typically originate from voltage or current sources, with the output often representing voltage across the capacitor and/or current through the inductor. For example, in...

First-order electrical circuits, which comprise resistors and a single energy storage element - either a capacitor or an inductor, are fundamental to many electronic systems. These circuits are governed by a first-order differential equation that describes the relationship between input and output signals.
One common example of a first-order circuit is the RC (resistor-capacitor) circuit. These circuits are used in relaxation oscillators such as neon lamp oscillator circuits. When voltage is...

In a balanced four-wire wye-to-wye system, the arrangement involves wye-connected sinusoidal voltage sources and loads, connected through a neutral wire that links the neutral nodes of the source and load. The load impedance is connected across each phase of the load. The wye-connected source can be connected to the wye-connected load in four-wire and three-wire arrangements. A three-phase system is considered balanced when the load on each phase is equal, leading to uniform current flow and...

3.2K
An LC circuit consists of an inductor and a capacitor, either in series or parallel. Consider a charged capacitor connected with an inductor in series. Before the switch is closed, all the energy of the circuit is stored in the electric field of the capacitor. When the switch is closed, the capacitor begins to discharge, producing a current in the circuit. The current, in turn, creates a magnetic field in the inductor. Because of the induced emf in the inductor, the current cannot change...

AC power distribution systems have three categories: single-phase, two-phase, and three-phase systems. The single-phase circuit, common in residential settings, typically employs a two-wire system connecting a single AC source to various loads. These circuits support standard household appliances operating at 120 volts (V) and 240 V, such as lamps, televisions, and microwaves. The first generators, Niagara Falls hydro plant installed in 1895, were two-phase and designed by Nikola Tesla. The...
