Transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), two non-invasive brain stimulation methods, have drawn a lot of interest recently as potential methods for modifying brain activity and controlling behavior. An overview of the present status of research on the possibility for non-invasive brain stimulation in several areas is given in this review study. Magnetic fields are used in TMS to create electrical currents in particular brain areas, which modifies neuronal activity. It has demonstrated promise in the treatment of several neurological and psychiatric conditions, including as schizophrenia, depression, and chronic pain. Numerous studies have documented considerable symptom improvements after TMS therapy. However, there are still issues including the requirement for specialized tools and the fleeting nature of its effects. On the other hand, tDCS modifies brain activity by delivering low-level electrical currents through electrodes positioned on the head. Additionally, it has demonstrated promise in the treatment of neurological and psychological conditions such chronic pain, anxiety, and depression. Numerous studies have documented considerable symptom reductions after tDCS treatment. The short-lived nature of its effects and the standardization of electrode placement and stimulation levels continue to be problems. Non-invasive brain stimulation approaches confront a number of difficulties in spite of the apparent advantages. Individual heterogeneity in response is noted, but the underlying mechanisms of action remain poorly understood. Additionally, although generally believed to be safe, any adverse effects demand careful monitoring and risk-benefit analysis. The study of non-invasive brain stimulation methods is advancing quickly. Studies have shown that they can improve motor skills as well as cognitive abilities like memory, focus, and decision-making. Further research is necessary due to the heterogeneity in response, lack of uniformity, and incomplete knowledge of causes. Conclusion: In both clinical and experimental settings, non-invasive brain stimulation approaches show promise for altering brain activity and controlling behavior. Even if there are still issues, continuous research presents chances for improving these methods and broadening their uses. To optimize the potential advantages of non-invasive brain stimulation for enhancing human brain function and wellbeing, future studies should concentrate on clarifying mechanisms, standardizing methods, and addressing individual variability..
