Electrosubcorticography

Electrosubcorticography (ESCG) is an electroencephalography method that allows you to study the activity of the human cerebral cortex. This method is used to diagnose and treat various neurological diseases such as epilepsy, depression, Alzheimer's disease and others.

Electrosubcorticography is based on measuring the electrical signals that are generated in the cerebral cortex when stimulated by various stimuli. These signals can be recorded using electrodes that are placed on the surface of the scalp. Then the obtained data is analyzed using special programs that allow you to determine the frequency, amplitude and other characteristics of electrical signals.

One of the advantages of ESCG is the ability to study cortical activity in real time. This allows doctors to observe changes in a patient's brain activity during various procedures or drug therapy. ESCG can also be used to determine the location of the epileptic focus in the patient's brain.

Overall, electrosubcorticography is an important method for diagnosing and treating neurological diseases and may become a key tool in the development of new treatments for these diseases.

Electrosubcorticography: study of the activity of deep brain structures

Electrosubcorticography (ESCG) is a method for studying the electrical activity of deep brain structures. The term “electrosubcorticography” is formed by combining elements from various languages: electro- (electric), Latin sub- (under), anatomical cortex cerebri (cerebral cortex) and Greek grapho (write, depict). Thus, ESCG makes it possible to record the electrical activity of structures located under the cerebral cortex.

Unlike electroencephalography (EEG), which measures electrical activity in the cerebral cortex, ESCG focuses on deep structures such as the basal ganglia, thalamus, hypothalamus, and other subcortical areas. These structures play an important role in the regulation of motor activity, emotions, sleep, as well as in the processing of sensory information.

The ESCG procedure involves implanting electrodes directly into the deep structures of the brain through surgery. Electrodes are placed in target areas selected based on clinical indications and study requirements. The electrical activity of the structures is then recorded and analyzed.

ESCG is a valuable tool for studying pathological conditions such as Parkinson's disease, epilepsy, depression and other nervous system disorders. Studies using ESCG may help clarify the pathophysiological mechanisms of these conditions and develop effective treatments.

One of the main advantages of ESCG is its high spatial and temporal resolution. Thanks to the precise positioning of electrodes and the ability to record signals at high frequencies, researchers obtain detailed information about the functioning of deep brain structures.

However, it is worth noting that ESCG is an invasive research method that is associated with certain risks. Surgical intervention for electrode implantation requires high qualifications and specialized equipment. Additionally, there is a risk of infection, bleeding, and other complications associated with the surgical procedure.

In conclusion, electrosubcorticography is an important research method for studying deep brain structures and their role in normal and pathological neural activity. This method allows us to obtain valuable data on the functioning of the basal ganglia, thalamus, hypothalamus and other subcortical areas. The use of ESCG may contribute to the development of new methods for diagnosing and treating various neurological and psychiatric conditions. However, it must be taken into account that ESCG is an invasive procedure and has its own risks and limitations. Further research and technology development in this area will help expand our understanding of the functioning of deep brain structures and apply this familiar tool to improve people's health and quality of life.
