What is rTMS?
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive method used to stimulate specific areas of the brain.
How is the rTMS coil positioned?
The coil is placed 1 cm lateral to the vertex on the biauricular line and angled at 45 degrees.
What precautions are taken during the procedure?
A rectal probe is used to monitor the rat's body temperature, maintaining it at 37 degrees Celsius.
Who demonstrates the rTMS procedure?
An experienced technician from the laboratory, Jin-Joo Lee, demonstrates the procedure.
What are the advantages of unilateral rTMS?
It allows for targeted stimulation and investigation of molecular mechanisms in one hemisphere of the brain.
What challenges do new users face with rTMS?
New users may struggle with the size of the coil and the timing of the motor threshold.
