The past thirty years have seen a revolution in our understanding of neural connectivity. The enormous amount of new neuroanatomical data has significantly altered our ideas about how different parts of the brain interact to control behavior. This chapter assesses what we currently understand about the neuroanatomical basis of motivated behaviors. These behaviors enable animals to organize their interactions with the goal objects that promote the survival of an individual or maintain sustainable numbers of individuals within a species. Four classes of behavior are recognized: ingestive and thermoregulatory behaviors, which are the behavioral adjuncts of physiological homeostasis, and defensive and reproductive behaviors, which organize those social interactions that are more concerned with individual security and the maintenance of the species.

In mammals, mothering is one of the most important prosocial female behavior to promote survival, proper sensorimotor, and emotional development of the offspring. Different intrinsic and extrinsic factors can initiate and maintain these behaviors, such as hormonal, cerebral, and sensory changes. Infant cues also stimulate multisensory systems and orchestrate complex maternal responsiveness. To understand the maternal behavior driven by complex sensory interactions, it is necessary to comprehend the individual sensory systems by taking out other senses. An excellent model for investigating sensory regulation of maternal behavior is a murine model of congenital blindness, the ZRDBA mice, where both an anophthalmic and sighted mice are generated from the same litter. Therefore, this study aims to assess whether visual inputs are essential to driving maternal behaviors in mice. Maternal behaviors were assessed using three behavioral tests, including the pup retrieval test, the home cage maternal behavior test, and the maternal aggression test. Our results show that blind mothers (1) took less time to retrieve their offspring inside the nest, (2) spent more time nursing and licking their offspring in the second‐ and third‐week postpartum, and (3) exhibited faster aggressive behaviors when exposed to an intruder male, compared to the sighted counterparts. This study provides evidence that congenitally blind mothers show more motivation to retrieve the pups, care, and protection towards their pups than sighted ones, likely due to a phenomenon of sensory compensation.
