There are remarkable differences between these strains in oxytocin and vasopressin and their receptors in a variety of limbic and other structures.
Relevant circuitry again interconnects processing systems with the orbital frontal, limbic (amygdala and hypothalamus), and brainstem (periaqueductal gray) regions.
Intracerebroventricular corticotropin-releasing factor increases limbic glucose metabolism and has social context-dependent behavioral effects in nonhuman primates.
Studies have also evaluated another limbic structure, the hippocampus, which is implicated in working memory for emotional events.
We assume, but have not proven, that these four groups of children inherit different profiles of limbic excitability which are based on different neurochemistries.
Adolescence and early adulthood are associated with continuing myelination of association cortex and limbic cortex, including the hippocampus.
He suggested that increased vivacity and frequency of dreaming was associated with anterior limbic lesions while recurring nightmares are associated with temporal seizures.
The initiation of maternal behavior thus involves specific neural circuitry; and with pregnancy, structural and molecular changes occur in specific limbic, hypothalamic, and midbrain regions.
