1. A method of modulating neural activity, the method comprising:
- providing a shunt electrode comprising an electrode and a passageway for fluid flow through the shunt electrode;
inserting the shunt electrode into a brain;
advancing the tip of the shunt electrode and curving it to conform to the contour of the ventricular anatomy;
curving the tip of the shunt electrode to reach both fornices by curving from one foramen of Monroe past the ipsilateral fornix to the contralateral fornix; and
modulating neural activity in the brain with the shunt electrode.

Abstract
The present application is directed to devices and methods that can treat dementia or other brain disorders via electrical stimulation. Embodiments disclosed herein utilize brain stimulation of brain areas involved in memory and cognition through an intraventricular approach. Brain stimulation is combined with CSF flow in an intraventricular electrode having one or more passageways to permit fluid to flow therethrough. For example, an intraventricular electrode shunt catheter can be safely placed in any part of the ventricular system and through any foramen or aqueduct of the ventricular system without fear of obstruction to CSF flow.
