speech delay with an unknown cause is a problem among children. this diagnosis is the last differential diagnosis after observing normal findings in routine hearing tests. the present study was undertaken to determine whether auditory brainstem responses to click stimuli are different between normally developing children and children suffering from delayed speech with unknown causes. in this cr...

the human brain is composed of several interconnected, functionally distinct structures and much debate has surrounded the basic question of how these structures evolve. brain development begins in early gestation. between 4 weeks and 9 months, brain undergoes rapid development. there are six stages of nervous system development. brain increases connections between birth and 21 years of age. ab...

background: previous studies have shown that morphine consumption during pregnancy may cause delay or defect of embryo development or abnormal nervous system function in the human and animal models. in the present study, the highest density of morphine accumulation in the central nervous system of rat embryos was evaluated using c14‑morphine. methods: female wistar rats (w 170‑200 g) used and w...

autism spectrum disorder (asd) is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with others and using language. in the last four decades many studies have shown that immune responses in different regions of brain play an important role in asd pathogenicity. a conservative estimate based on the research suggests tha...

performance and development are based on hard work, experience and learning. learning how to change different behaviors is crucial to successful talent management plans. within the brain there are complex connected circuits that can identify threats. the brain reacts to change as a threat. there is also a collection of brain structures tied to a natural reward system that are involved in the re...

introduction: survivin, an inhibitor of apoptosis (iap) containing one baculoviral iap repeat (bir) domain, has been reported to be able to regulate both cellular proliferation and apoptotic cell death. in the present study, we evaluated the differential expression of different variants of survivin during prenatal and postnatal development of brain in mice. material and methods a total of 27 nm...

in this study tsga10 has been demonstrated as a testis-specific human gene that encodes a protein localized in sperm-tail and conserved in ciliary structure. further investigations showed tsga10 signalling and expression during embryogenesis, brain development and some malignancies including brain tumors. given the role of this protein in neuronal development and in certain tumors, it could pot...

The prenatal period is a critical time for neurodevelopment and is thus a period of vulnerability during which a range of exposures have been found to exert long-term changes on brain development and behavior with implications for physical and psychiatric health. During fetal life, neurons proliferate, migrate and form connections, providing the structure of the developing brain. Neurons reach ...
