Researchers have been carried out in all aspect of life to find out cause thing to happen. Why thing function the way they do and why our body faces problems that we were not originally born with but develop over time. In biology researcher have done way procedures to find out why people feel the way they do. The researcher has used different methods to carry out these findings. They have used the invasive and non invasive methods to carry out their procedures.

Non-invasive method is a medical procedure is strictly when no break in the skin is created and there is no contact with the mucosa, or skin break, or internal body cavity beyond a natural or artificial body orifice. There are many non-invasive procedures, ranging from simple observation, to specialized forms of surgery, such as surgery. For as long as I can remember and , physicians have employed many simple non-invasive methods based on physical parameters in order to assess body function in health and disease physical examination and inspection, such as pulse-taking, the auscultation of heart sounds and lung sounds using the  stethoscope  temperature using thermometers, respiratory examination, peripheral vascular examination, oral examination[disambiguation needed], external percussion and palpation, blood pressure measurement (using the sphygmomanometer), change in body volume using plethysmograph, audiometric, eye examination and many others.

An invasive brain stimulation technique; involves stimulation of the brain by surgically opening the skull and delivering a measured electrical current to a specific brain area or structure. The invasive methods are procedure typically involves use of arthroscopic (for joints and the spine) or laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or large scale display panel, and is carried out through the skin or through a body cavity or anatomical opening....
