In a research project, the experimental group underwent a painful procedure followed by an injection of an opioid painkiller. Th
e control group was injected with a saline solution placebo after the procedure. A PET scan revealed that, in one participant, an area of the brain called the anterior cingulate cortex became very active. It is likely that the person who reported that the injection provided pain relief: Could have been in either the experimental group or the control group. T/F
PET scan positron emission tomography is a special image test that can show how different tissues in the body is functioning or in the case of the brain reacting to stimuli.
In this case the cingulate cortex is the area of the brain linked to reactions involving pain or painful stimuli. If a person has undergone a painful procedure and was not given any relief this area will be activated and will be able to be detected on a PET scan. On the contrary, if one has received pain relief this will not be the case. So, an active cingulate cortex will be observed on a PET scan for a subject in pain.
Rather than helping one species you can help a entire ecosystem. if you think about it, you would be saving more in a ecosystem then you would in just 1 single species
