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 in, role and/or behavior:
“If women’s role in life is limited solely to housewife/mother, it clearly ends when she can no longer bear more children and the children she has borne leave home.”
—Betty Friedan (20th century)
“A few [women] warrant our attention not because they have the answer but because they have rejected the mentality that insists there must be one answer. What makes them role models is not how much or how little they work, how many or how few hats they wear, but rather how well they understand, and accept, that for all rewards there will be commensurate sacrifice; for all gains, some loss; for any pleasure, some pain.”
—Melinda M. Marshall (20th century)
“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
—William James (1842–1910)
