In particular, age-related changes within so-called Broca's area have been a focus of many developmental language studies (reviewed in Berl, Mayo et al. 2014).
Child brain normalization is an accepted method in many developmental fMRI studies (Brown et al. 2005; Dekker et al. 2011); from 6 7 years of age, standard normalization procedures do not lead to registration problems (Muzik et al. 2000; Kang et al. 2003; Wenger et al. 2004).
Since some of these genes have been revealed to be essential for embryonic development, we propose that the zebrafish, a vertebrate model organism possessing many advantages for developmental studies, can be utilized to study the biological functions of these genes and the related epigenetic mechanisms during early development.
Many of the developmental studies have used pure numerical estimation with large number scales (e.g. 0-100 and 0-1000: [ 2, 5, 10]).
Application of the LCM-LC-MS/MS approach to dentoalveolar tissues would be of value in many experimental designs, including developmental studies of transgenic animals, investigation of treatment effects, and identification of novel regenerative factors.
Zebrafish is an excellent model for many developmental, toxicological and regenerative studies.
The relative contribution of different mechanisms to adaptive phenotypic variation has been the focus of many recent evolutionary and developmental studies and the subject of much debate [ 1- 4].
Lymphoid development has been extensively studied, many developmental stages are known, and there is a large amount of available data on distinct stages of development and in several cell lineages (see Figure 3 (left)).
Neurotrophins were traditionally thought of as being produced by the targets of sensory neurons, but it became apparent from developmental studies that many sensory neurons can actually express and produce neurotrophins (Ernfors et al., 1990).
