(MK Often) Subtle interactions of environmental signals drive neuronal differentiation and the formation of synapses and brain circuits. The development of limbic structures such as the hippocampus and the amygdala can be modulated by sensory as well as emotional experience during early postnatal life.This adaptability of the developing brain toward adverse environmental influences such as sensory and emotional deprivation or stress has been studied in various animal models. Application of paradigms for stressful experience such as maternal separation and the exposure to an unfamiliar environment has been shown to induce altered aminergic transmitter function (as well as long-term changes of synaptic composition which mediate learning and memory formation which may result in altered cognitive and socio-emotional capabilities at later stages of life. Thus, one aim is to study the effects of stressful and fear-inducing situation, i.e., separation from the family and exposure to a novel environment.) as it relates to life styles and life choices in human development. The consequences of early aversive environmental stimuli on brain function can be ameliorated or prevented by the interaction with the mother via her sensory signals, including visual, olfactory, tactile, and acoustic stimuli .Maternal vocalization is an essential part of the establishment and maintenance of the infant–mother attachment and mental development newborns which allows them to recognize, learn, and interpret acoustic signals and to respond to simulations of such input by indirect means.
