how many neurons are in the brain at birth

We propose light as a robust candidate for the CNS activation via the retina. This stimulus must have specific features though, such as novelty, efficacy, ubiquity, and immediacy. This ‘hypothesis and theory’ article assumes the role of a specific stimulus activating the central nervous system (CNS) at human birth. To date, few researchers only have investigated the impact of the extrauterine environment, with its strong stimuli, on birth. The trigger of the first breath, often assumed to be the marker of human life, has not been characterized nor has the process entailing brain modification and activation at birth been clarified yet. 5Chair of Pediatrics, Department of Neuroscience, Mental Health and Sensory Organs NESMOS, Sant'Andrea Hospital, Sapienza University of Rome, Rome, Italyĭevelopmental neuroscience research has not yet fully unveiled the dynamics involved in human birth.4PhD Program on Neuroscience, Department of Systems Medicine, Tor Vergata University, Rome, Italy.
