Neuromodulation is a neuroscientific term that refers to the process by which the brain's activity is modulated or adjusted by various internal and external mechanisms. This can involve changes in the release, binding, or reception of neurotransmitters, hormones, or other signaling molecules that convey information between neurons. Neuromodulation enables the brain to adapt to changing environments, learn new information, and recover from injury or disease.

Neuromodulators can be categorized into two main types: endogenous and exogenous. Endogenous neuromodulators are those that are produced within the body, such as neurotransmitters and hormones. Exogenous neuromodulators, on the other hand, are external agents, such as medications, that can influence brain activity.

Various techniques and technologies have been developed to manipulate and modulate brain activity for therapeutic or experimental purposes. These include neurotransmitter-based treatments, such as selective serotonin reuptake inhibitors (SSRIs) for depression, and more invasive methods, such as deep brain stimulation (DBS) and vagus nerve stimulation (VNS). Other non-invasive techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), have also been used to modulate brain activity in healthy individuals and those with neurological or psychiatric conditions.

Research on neuromodulation has led to major advances in the treatment of various neurological and psychiatric disorders, including Parkinson's disease, depression, and anxiety disorders. Additionally, studies have shed light on the complex interactions between different brain regions and systems, highlighting the importance of understanding the intricate processes underlying neural communication and control.
