In deep brain stimulation, electrodes – the pale white lines – are implanted into a patient’s brain and connected to a battery in a person’s chest.
Deep brain stimulation and trasncranial magnetic stimulation treat mental illness by sending electrical currents into parts of the brain. Every new patient provides researchers with a wealth of information. Listen to The Conversation Weekly podcast.

Patients who undergo transcranial magnetic stimulation say it’s painless, with few to no side effects. The treatment isn’t yet widely accessible, but for those who use it, the effects can be profound.
In this week’s federal budget we heard how this non-drug treatment for depression will be available on Medicare for people who’ve not responded to antidepressants.
The teenage brain has a voracious drive for reward, diminished behavioural control and a susceptibility to be shaped by experience. This often manifests as a reduced ability to resist high-calorie junk foods.
Excessively eating junk foods during adolescence could alter brain development, leading to lasting poor diet habits. But, like a muscle, the brain can be exercised to improve willpower.
Dr. Zahra Moussavi tests a device that stimulates the brain with magnetic pulses. The experimental technology can temporarily roll back effects of Alzheimer’s disease.
When Zahra Moussavi’s mother developed Alzheimer’s, the scientist pursued a technology that directly stimulates the brain with electromagnets to mitigate the effects of the disease. It worked.

Four stories on belief: from the allure of cults and conspiracy theories, to the effect of trauma on faith, to the way dogma has influenced science – and if technology can actually shift our beliefs.

People who electrically stimulate their brains at home need more information to do it safely… and neuroscience needs to find out more about how and why they do it.
Now’s the time to think about what we’re getting into with neurotechnologies.

Repetitive transcranial magnetic stimulation is an approved treatment for depression. A new study suggests that it may be effective at treating anorexia too.
