Answer to Question 1

In the first brain imaging methods, computerized axial tomography (CT), the images of the brain are collected on X-ray film. These images are then processed by a computer to generate visually and physically meaningful images. In magnetic resonance imaging (MRI) the image is derived from signals generated by changes in the levels of electromagnetic radiation from tissues under observation. Magnetic resonance spectroscopy (MRS) extends the capacity of the MRI to permit the study of tissue chemistry and metabolic function. Single photon emission computed tomography (SPECT) provides direct measurement of blood flow and several specific physiological and neurochemical features of the brain.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
