There are devices that are both tcds and tms that lower the action potential in various parts of the brain to treat illnesses, improve cognition, etc. So what about the opposite, are there interventions that can increase the threshold of action potential in parts of the brain to make those neurons fire more slowly? If so, what therapeutic (both psychological and physical) would those kinds of interventions hold?
It is my understanding that the ratio of activity in the left and right prefrontal cortex can influence moods. The more activity in the left and the less in the right = higher emotional states. So lowering the action potential in the left and raising it in the right could be a treatment for depression. Using TMS on the left prefrontal cortex is used to treat depression. I know there are some devices that use TCDS on both the left and right prefrontal cortex to increase cognition. But I don’t know if anything can be done to increase the action potential in various parts of the brain for therapeutic purposes.
Does anyone know?
