Using Transcranial Magnetic Stimulation (TMS) to Understand 'Negative' Symptoms of Schizophrenia

"rTMS is a technique of TMS that allows the selective external manipulation of neural activity in a non-invasive manner. During TMS, a rapidly changing current is passed through an insulated coil placed against the scalp. This generates a temporary magnetic field that in turn induces electrical current in neurons and allows the modulation of neural circuitry. The combination of TMS with fMRI allows the selective targeting and modulation of brain networks. The repeated application of rTMS can cause long term changes in behavior and task performance that is reflected in altered brain network connectivity.~The pattern of rTMS will consist of either:~intermittent Theta Burst Stimulation (iTBS) pattern consisting of 2 s trains of 3 pulses at 50 Hz, repeated at 5 Hz, every 10s for a total of 600 pulses.~OR~sham stimulation"
