Final Answer:
The placement of the anode and cathode on the Transcranial Magnetic Stimulation (TMS) coil can affect the depth and focus of the induced magnetic field.
Step-by-step explanation:
In Transcranial Magnetic Stimulation (TMS), the anode and cathode refer to the coil configuration. If the anode and cathode are far apart on the TMS coil, it generally leads to a deeper penetration of the magnetic field into the brain. This configuration is often used when targeting deeper brain structures.
On the other hand, if the anode and cathode are close together on the TMS coil, it results in a more focused and superficial stimulation. This configuration is preferred when the goal is to target specific areas closer to the surface of the brain.
The distance between the anode and cathode on the TMS coil is a crucial factor in determining the spatial characteristics of the induced magnetic field and, consequently, the regions of the brain that are stimulated.
In summary, the placement of the anode and cathode on the TMS coil influences the depth and focus of the induced magnetic field, allowing for targeted stimulation of different brain regions.
