DIAS, Gisele P. and REIS, Ricardo A. M.. Synaptic plasticity: nature and nurture shaping the self. Psicol. Reflex. Crit. [online]. 2009, vol.22, n.1, pp. 128-135. ISSN 1678-7153. http://dx.doi.org/10.1590/S0102-79722009000100017.
The developing brain requires a genetic plan, established by the evolutionary history of human species, but it is also very sensitive to the surrounding environment. Environmental stimuli can modify the structure of neural circuits, refining and making synapses, which are the target of neurotransmitters, more efficient by electrical activity and chemical messengers. The aim of the present study is to discuss theoretically how both plasticity and previous specification of brain systems coexist in the brain. The conclusion shows the importance to integrate aspects of social learning and biology in building and refining the various humane skills.
