The electrical signaling within each neuron is not just of
theoretical interest. Knowing the electrical basis of brain functioning
offers an understanding of disorders such as epilepsy, so that
physicians can help people avoid or control seizures. There is growing
evidence that implanting electrodes in the brain can offer relief for
movement and mental disorders. However, the power to manipulate the
brain’s electrical signals raises ethical questions. Does society have
the right to force someone to receive electrical stimulation in the
brain? For example, would it be acceptable to implant an electrode in
the brain of a person convicted of murder that prevents the person from
being aggressive?
For this week’s Discussion, you examine the electrical properties
of individual neurons and the ethical implications of electrical brain
stimulation.
With these thoughts in mind:
Post by Day 4 a brief description of the
electrical properties of an individual neuron. Then explain how those
properties may change over time. Finally, describe the potential ethical
implications of implanting an electrode in the brain of a person
convicted of murder that prevents the person from being aggressive,
instead of sending him or her to prison. Support your postings and
responses with specific references to the literature and Learning
Resources.
