Susan Blackmore. Transcranial magnetic stimulation. Background[edit] Early attempts at stimulation of the brain using a magnetic field included those, in 1910, of Silvanus P. Thompson in London.[2] The principle of inductive brain stimulation with eddy currents has been noted since the 20th century. The first successful TMS study was performed in 1985 by Anthony Barker and his colleagues at the Royal Hallamshire Hospital in Sheffield, England.[3] Its earliest application demonstrated conduction of nerve impulses from the motor cortex to the spinal cord, stimulating muscle contractions in the hand.
As compared to the previous method of transcranial stimulation proposed by Merton and Morton in 1980[4] in which direct electrical current was applied to the scalp, the use of electromagnets greatly reduced the discomfort of the procedure, and allowed mapping of the cerebral cortex and its connections. Theory[edit] From the Biot–Savart law it has been shown that a current through a wire generates a magnetic field around that wire.

Think you have clear standards of right and wrong written into your brain? Think again. In April neuroscientist Liane Young and her colleagues at MIT and Harvard University reported that they had altered people’s moral judgments using transcranial magnetic stimulation, a procedure that briefly disrupts neural processing with a magnetic field induced by electric current.
Young asked each of 20 volunteers to judge 24 scenarios that involved morally questionable behavior. (One example: Grace slips her friend what she thinks is poison but is actually sugar. The friend is unaffected. How immoral is Grace’s action?) Before and after, the subjects rated the scenarios on a seven-point scale, ranging from morally forbidden to morally permissible. Manipulating morality with a magnet may sound diabolical, but Young has no interest in mind control.
Neuroscience. Neuroscience is the scientific study of the nervous system.[1] Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation[2] and neurolaw. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators. History[edit] The study of the nervous system dates back to ancient Egypt.
