normally.
• Monoamine

• Malfunctioning

Neuron
TMS Directly Depolarizes Cortical
Neurons
Pulsed magnetic fields
from TMS Coil:
• induce a local electric
current in the cortex
which depolarizes
neurons
• elicit action potentials
• cause the release of
chemical
neurotransmitters
Depolarization leads to action
potentials in local neurons and
thereby releases neurotransmitters
Neurons are
“electrochemical
cells” and respond to
either electrical or
chemical stimulation
![Page 16: 04 09-12 neuro-modulation power point](https://reader034.fdocuments.net/reader034/viewer/2022051516/55a566121a28ab80248b45b6/html5/thumbnails/16.jpg)
TMS Releases Neurotransmitters
in the Brain
Depolarization of neurons
in the DLPFC causes local
neurotransmitter release
Depolarization of pyramidal
neurons in the DLPFC causes
neurotransmitter release in
deeper brain neurons
Activation of deeper brain
neurons then exerts secondary
effects on remaining portions of
targeted mood circuits
Dorsolateralprefrontal
cortex
Cingulate cortex
Kito (2008) J Neuropsychiatry Clin Neurosci
These effects are
associated with
improvements in
depressive symptoms

TMS Mechanism of Action Summary
TMS Therapy:
Specifically targets the underlying brain circuits involved in mood regulation
Directly depolarizes cortical neurons and modulates neurotransmitter release in the brain
Effects involve both the local and deep neural circuits in the brain
Accomplishes these effects without unwanted systemic adverse effects
