| 释义 | limbic adjective biology specializeduk /ˈlɪm.bɪk/ us /ˈlɪm.bɪk/ the limbic system a system of nerves and other structures in the brain that controls many of our emotions : 大脑边缘系统 Powerful emotions are processed in the limbic system. forming part of, or relating to, the limbic system: 边缘系统的 the limbic area of the brain大脑边缘区域 The brain & nervous system abducens nerve abducent nerve accessory nerve alexithymia allism glossopharyngeal nerve grey matter hemispheric hemispherical hindbrain neurogenic neurogenically neuroglia neuroglial neurohormonal reticular formation rhinencephalon rhombencephalon right brain right-brained Examples of limbiclimbic 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. Other mammals have only rigid, species-specific, limbic vocalizations. Resilience would be increased by processes that restore prefrontal cortex and limbic cortex function. The disease subsequently spreads from the limbic stage to the neocortex. The processing of facial emotion involves a distributed network of limbic and paralimbic brain structures. Information can thus be channeled from limbic to cognitive and to motor circuits at the subcortical level, allowing for appropriate responses to environmental cues. Chaotic behavior within the excitatory and inhibitory limbic circuits is thus expressed in sudden psychobiological state transitions. Failure in plasticity is considered to be an agerelated phenomenon, to which the limbic and paralimbic cortices are particularly vulnerable.
