  The brain stimulation and its widespread use is one of the most important
subjects in studies of neurophysiology. In brain electrical stimulation
methods, following the surgery and electrode implantation, electrodes send
electrical impulses to the specific targets in the brain. The use of this
stimulation method is provided therapeutic benefits for treatment chronic pain,
essential tremor, Parkinsons disease, major depression, and neurological
movement disorder syndrome (dystonia). One area in which advancements have been
recently made is in controlling the movement and navigation of animals in a
specific pathway. It is important to identify brain targets in order to
stimulate appropriate brain regions for all the applications listed above. An
animal navigation system based on brain electrical stimulation is used to
develop new behavioral models for the aim of creating a platform for
interacting with the animal nervous system in the spatial learning task. In the
context of animal navigation the electrical stimulation has been used either as
creating virtual sensation for movement guidance or virtual reward for movement
motivation. In this paper, different approaches and techniques of brain
electrical stimulation for this application has been reviewed.
