Resumen:
Grooming is a fundamental component of the social cohesion of Nonhuman primates (NHP) because its plays an important role in the establishment and maintenance of social ties. There is evidence that some aspects of sociability change through development. Grooming is based on a complex relationship between the sensory system and the motor system, requiring sophisticated manual dexterity. As in other mammals, newborn Rhesus monkeys have a remarkable sensory, motor and homeostatic immaturity, as their motor and sensory systems undergo developmental changes that are deployed reciprocally, parallel to the process of maturation and myelination of the Nervous System (NS), where their structures are organizing, differentiating and specializing their functions for the acquisition of more complex behaviors. The period in which the different nerve fiber systems are myelinated is highly variable. Myelin is deposited first in the pathways of greater phylogenetic age, beginning in the sensorimotor system followed by the secondary cortical areas, and lastly the frontal, parietal and temporal cortex. Myelination begins at different times and has a variable rhythm and duration for each NS region. Spinothalamic and spinocerebellar bundles present myelination at the beginning of the first trimester of intrauterine life, whereas the corticospinal bundles begin to myelinate towards the end of gestation but take several years to complete. According to the scientific literature, the maturation of the NS occurs in utero for old world monkeys, resulting in a larger and more highly myelinated brain at birth (65% of adult size), compared to other species of mammals (including humans). The development of organisms is dependent on neurological maturation. This neurological development is a continuous process, with a predetermined sequence and an inhomogeneous velocity, which does not occur in parallel in the different areas of development. It is for this reason that the acquisition of more complex behaviors that allow individuals to interact with their environment and improve their survival is directly proportional to neurological development and maturation. © 2018 Nova Science Publishers, Inc.
