The scanning or probing movements have also been hypothesized to help recognize object features.
The movements that these electric fish use allows for the recongition of an object's features. Evidence from Heiligenberg's stimulation show that when electric fish bend their tails it increases the spatial contrast and makes it easier to distinguish an object's features. While Bacher's 3-D model showed that fish's tail bending help show a clear difference between the object's location and its shape . The BEM stimulation showed that electric fish control their movement in order to regulate their electrosensory system input by demonstrating a stable image of the rostral body which is thought to help the fish to distinguish features. - Michelle Gomez-Guevara
