Ques-: Please briefly describe the common heirarchial organization in neural circuits of animal behaviors, such as aggression and courtship? Answer: A hierarchical system of neural structures in relation to animal behavior: In animals, it has observed that “limbic system” and central nervous system in coordination with autonomic nervous system to deliver motor activity through aggression and courtship. Initially the neural circuits have developed in invertebrates to aquatic specific finally; a mature developed brain has developed in mammals to deliver aggression and motivation. Reward related behavior has strengthened hierarchically “as part of mid brain nigrostraital and mesolimbic pathway” involved mainly in animal behaviour and motivation. The hormones such as adrenaline and testosterone (in case of some animals) & serotonin are delivered from neural structures to interact with cellular mediators as per sensory perception through electrical stimulation Ques-2: In case of vertebrate mice, cellular mechanisms for scalable control of mounting and attack behaviors are mainly involve the “reinforced cortico-striatal pathway” of limbic system. The electrical stimulation neuronal bodies in the midbrain are going to trigger aggressive behavior whereas hypothalamic perceptions are going to control mounting and attacks on other species.
