Role in Behavior
The olfactory tubercle has been shown to be primarily concerned with the reception of sensory impulses from olfactory receptors (Adey 1959). Because of its connections to regions like the amygdala and hippocampus, the olfactory tubercle may play a role in behavior. Rats rely heavily on olfactory sensory input from olfactory receptors for behavioral attitudes (Barnet 1963). Studies show that bilateral lesions in the olfactory tubercle significantly reduce stereotyped behavior (McKenzie 1972; Asher & Aghajanian 1974) such as copulatory behavior in male rats and a reduction in sniffing and chewing behaviors (Koob et al. 1978). These stereotyped inhibitions may have been caused by the removal of central neuronal processes other than the dopaminergic cells in the olfactory tubercle. Unilateral lesions have been shown to alter attention, social and sensory responsiveness and even locomotor behavior in rats (Koob et al. 1978).

Famous quotes containing the words role and/or behavior:
“The role of the writer is not simply to arrange Being according to his own lights; he must also serve as a medium to Being and remain open to its often unfathomable dictates. This is the only way the work can transcend its creator and radiate its meaning further than the author himself can see or perceive.”
—Václav Havel (b. 1936)
“Gaining a better understanding of how childrens minds work at different ages will allow you to make more sense of their behaviors. With this understanding come decreased stress and increased pleasure from being a parent. It lessens the frustrations that come from expecting things that a child simply cannot do or from incorrectly interpreting a childs behavior in adult terms.”
—Lawrence Kutner (20th century)
