Аннотация:Significance Two different kinds of exploratory behavior, object and place, have been proposed. Their distinction has been debated, however, because of the lack of solid experimental evidence to support their heterogeneity. In this report, we show neural evidence for the heterogeneity of exploratory behaviors. Thus, we demonstrate that T-type Ca 2+ channels in the septo-hippocampal GABAergic pathway play a specific role in control of exploratory behavior of novel objects. In addition, we show that type 2 but not type 1 hippocampal theta rhythm is associated with object exploration.
