Description

The neuroscience of drugs for therapy, for prevention, and for recreation. Drug addiction and drug abuse. You learn the prospects for new generations of medications in neurology, psychiatry, aging, and treatment of substance abuse.

About the Course

What happens in the body when a person smokes a cigarette? After several weeks of smoking? When a person takes antidepressant or antipsychotic medication? A drug for pain, migraine, or epilepsy? A recreational drug? Neuroscientists are beginning to understand these processes. You’ll learn how drugs enter the brain, how they act on receptors and ion channels, and how “molecular relay races” lead to changes in nerve cells and neural circuits that far outlast the drugs themselves. “Drugs and the Brain” also describes how scientists are gathering the knowledge required for the next steps in preventing or alleviating Parkinson’s, Alzheimer’s, schizophrenia, and drug abuse.

Recommended Background

Neuroscience, the most interdisciplinary science of the 21st century, receives inputs from many other fields of science, medicine, clinical practice, and technology. Previous exposure to one or more of the subjects listed in “Suggested Readings” will provide a good vantage point, as we introduce material from these subjects.

Health and Medical course

More information about Medical:

Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease.
Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness.
Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease,
typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Medicine has been around for thousands of years, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and
philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism.
In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (both basic and applied, under the umbrella of medical science).
While stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.
