behavioral indicators of fear (such as freezing). This test allowed them to compare the relative fear behavior of rats under microstimulation in either subregion to normal rats in the same condition. The researchers concluded that the prelimbic subregion excites fear behavior while the infralimbic subregion inhibits fear behavior. In this instance, the correlation between stimulation and behavior helped identify the function of these two subregions in the process of fear.

research to identify the functional significance of a group of neurons. For example, Vidal-Gonzalez et al. (2006) applied microstimulation to the rat prelimbic and infralimbic subregions of the medial prefrontal cortex while testing the subjects in a fear-inducing low-footshock condition for various
