In the comfort of his own home, Aaron Grinter is administering a new treatment that could change his life.
The 30-year-old has battled depression for more than 10 years and has taken the first steps to improve his mental health.
He is participating in a trial that uses electricity to increase the activity of neurons in his brain.
"This treatment seems different because it's not any of the things that are available at the moment, and it's non-invasive," Aaron said.
The practice is called Transcranial Alternating Current Stimulation (tACS) and it is part of a trial run by Paul Fitzgerald at the Epworth Centre for Innovation and Mental Health.
