Abstract Transcranial magnetic stimulation TMS has quickly progressed from a technical curiosity to a bona-fide tool for neurological research. The impetus has been due to the promising results obtained when using TMS to uncover neural processes in normal human subjects as well as in the treatment of intractable neurological conditions such as stroke chronic depression and epilepsy. The basic principle of TMS is that most neuronal axons that fall within the volume of magnetic stimulation become electrically excited trigger action potentials and release neurotransmitter into the postsynaptic neurons. What happens afterwards remains elusive especially in the case of repeated stimulation. Here we discuss the likelihood that certain TMS protocols produce longterm changes in cortical synapses akin to long-term potentiation and long-term depression of synaptic transmission. Beyond the synaptic effects TMS might have consequences on other neuronal processes such as .
