Various databases including Pub Med, Google, Google Scholar and Medline were searched for references related to auditory evoked potentials in musicians from 1994 till date. Different auditory evoked potentials in musicians have been summarized in the present article. The findings of various studies may support as evidences for music-induced neuroplasticity which can be used for the treatment of various clinical disorders. The search results showed enhanced auditory evoked potentials in musicians compared to non-musicians from brainstem to cortical levels. Also, the present review showed enhanced attentive and pre-attentive skills in musicians compared to non-musicians.展开更多

Although most of the samples analyzed are generally altered, a few are fresh. The latter exhibits similar geochemical and isotopic characteristics to normal MORB （Mid-Ocean Ridge Basalts）. There are systematic geochemical trends from hotspot to mid-ocean ridge in the province. Incompatible element and isotopic variations suggest that the flow field had at least two distinct parental magmas, one with higher and one with lower MgO concentrations. The two parental magmas could be related by a magma mixing model. The major and trace element modeling shows that the two parental magmas could not have been produced by different degrees of melting of a homogeneous mantle source, but they are consistent with melting of a generally depleted mantle containing variable volumes of embedded enriched heterogeneity enriched interbeds.展开更多

The objective of this study was to assess the otological damage of military music professionals in Cotonou. <strong>Methods:</strong> This was an analytical cross-sectional study carried out from July 15 to November 15, 2019. It focused on soldiers from the Music Squadron and the first Motorized Intervention Battalion of Camp Guézo in Cotonou. <strong>Results:</strong> 110 soldiers were included. The mean age was 34.3 ± 6.2 years. The sex ratio was 17.3. The instruments used were wind (74.5%), percussion (23.6%) and string (1.8%). The average length of service in the Music Squadron was 11.5 ± 6.7 years with extremes of 1 year and 25 years. They practiced military music for an average of 4.58 hours per day for 4 days per week. The mean sonometric measurement during training ranged from 89.1 dB (A) to 116.4 dB (A). Hearing loss was predominant in the military musicians group and was mild degree bilaterally (p = 0.002) and perceptual type (p = 0.007). <strong>Conclusion:</strong> Military musicians are exposed to high noise levels, putting them at risk of developing hearing problems that may limit their performance. The main otological morbidity found was hearing loss associated with a few cases of tinnitus and headache.展开更多

From her perspective, Chinese left-wing literature was featured by its revolution and popularity; Chinese left-wing writers were busy with creating different genres to get every Chinese＇s involvement in the anti-Japanese war in 1930s and participation in the construction of new China in 1940s. Hence, they were multifarious in their identity because they cared more than literature in a turbulent time. From what she presented, China, as a cultural otherness, was the existent utooia that fulfilled her radical nolitical dream of communism.展开更多
