Sometimes in order to study parts of an animal's brain, researchers may deliberately damage a part of the brain. they accomplish this by placing into the brain a thin insulated wire through which they send an electrical current that destroys the brain cells at the tip of the wire. this technique is called

The correct answer will be- lesioning

Explanation:

Lesioning is a technique used to treat severe movement disorders related to Parkinson's disease.

In lesioning, the lesions (damage) are created in a small part of the brain related to the movement by sending an electric current through a thin insulated wire.

This technique nowadays used in research centres to study the different parts of the brains to study the functions related to the brain.

Thus, lesioning is the correct answer.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
