“Electric Fields Play Dominant Role in Transcranial Magneto-Acoustic Stimulation Modulating Synaptic Plasticity” could be a suitable title for the text, as it highlights the main finding of the study that electric fields are the primary factor in modulating synaptic plasticity in transcranial magneto-acoustic stimulation. However, it’s worth noting that the title case has been used here for better readability. If you require a title that strictly avoids the use of title case, you could use a slightly different formulation, such as: “Electric Fields’ Dominant Role in TMAS: Amplitude Matters More Than Acoustic Pressure for Synaptic Plasticity Modulation”
