What is EEG and Brain Mapping? EEG or electroencephalography is the measurement of electrical patterns on the surface of the scalp that reflect cortical activity and are commonly referred to as brain waves. Meanwhile, brain mapping or quantitative EEG (qEEG) is a digital EEG analysis. It can be said that qEEG is an extension of visual EEG interpretation analysis that can help, even increase understanding of EEG and brain function. So, brain mapping or qEEG is a procedure that processes EEG activity recorded from multielectrode recordings using a computer. All neuroimaging can be considered as part of brain mapping. Brain mapping can be understood as…

Pleural Effusion Definition Pleural effusion is a condition where there is abnormal fluid in the pleural cavity. You need to know, the pleura is a thin membrane that lines the lungs and chest wall. Although they both attack the lungs and are associated with abnormal fluid, pleural effusion is different from wet lungs. Wet lung disease occurs due to an infection that causes inflammation of the alveoli or air sacs in the lungs. Between the pleura lining the lungs and the chest wall, there is a pleural cavity. Normally, there is a small amount of fluid in this cavity which functions as…

What is Ejaculation? Ejaculation is when semen or sperm comes out of the penis. This process usually occurs as a result of sexual stimulation that causes orgasm which is the peak of sexual sensation. Ejaculation can occur during sexual intercourse, masturbation, or even without direct stimulation, as in the case of a wet dream. The semen released contains sperm, which is necessary for reproduction. The ejaculation process is controlled by the nervous system. Well, the nerves that connect the reproductive system to parts of the spine will force semen out of the penis when sexual stimulation reaches its peak. In…

Pulmonary Edema Pulmonary edema is a serious medical condition that occurs when excess or buildup of fluid begins to fill the air sacs in the lungs (alveoli). When filled with fluid, the alveoli cannot adequately add oxygen, or remove carbon dioxide from the blood. That is why this condition can cause significant breathing difficulties, and potentially be a life-threatening problem. Symptoms of Pulmonary Edema Acute conditions can cause significant breathing difficulties and can appear without warning. This is an emergency and requires immediate medical attention. This condition can be fatal without proper treatment and support. Along with difficulty breathing, other…

What is Edema? Edema is swelling that occurs due to too much fluid being trapped in body tissues. This condition can occur anywhere on the body, but most often appears in the legs and feet. This health disorder can occur due to many factors. Starting from heart failure, kidney disease, venous insufficiency, or liver cirrhosis, as well as special conditions such as pregnancy and drug consumption. Edema can actually subside on its own when sufferers reduce their salt intake and improve their diet. However, in some conditions, edema needs to be treated by a doctor. Especially if the edema that…
