The functional foetal brain: A systematic preview of methodological factors in reporting foetal visual and auditory capacity
نویسندگان
چکیده
Due to technological advancements in functional brain imaging, foetal brain responses to visual and auditory stimuli is a growing area of research despite being relatively small with much variation between research laboratories. A number of inconsistencies between studies are, nonetheless, present in the literature. This article aims to explore the potential contribution of methodological factors to variation in reports of foetal neural responses to external stimuli. Some of the variation in reports can be explained by methodological differences in aspects of study design, such as brightness and wavelength of light source. In contrast to visual foetal processing, auditory foetal processing has been more frequently investigated and findings are more consistent between different studies. This is an early preview of an emerging field with many articles reporting small sample sizes with techniques that are yet to be replicated. We suggest areas for improvement for the field as a whole, such as the standardisation of stimulus delivery and a more detailed reporting of methods and results. This will improve our understanding of foetal functional response to light and sound. We suggest that enhanced technology will allow for a more reliable description of the developmental trajectory of foetal processing of light stimuli.

Intracerebral transplantation of foetal neural stem cells improves brain dysfunction induced by intracerebral haemorrhage stroke in mice
Intracerebral haemorrhage (ICH) can lead to secondary insults and severe neurological deficits. Transplantation of neural stem cells (NSCs) was suggested as an alternative to improve ICH-induced neurological dysfunction. The present study aimed at investigating the therapeutic role and long-term survival of foetal NSCs and potential role of foetal NSCs-produced factors in ICH. Our results demon...

Background and purpose: Maternal-foetal attachment (MFÂ) is a term which describes the relationship between a pregnant women and her foetus. Mothers with high MFÂ show more confidence in their new role and a better postpartum adjustment. The present study was conducted to determine the effect of counting foetal movement on maternal-foetal attachment. Materials and methods: This interventio...
متن کاملSelective deficits in human audition: evidence from lesion studies
The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

Background: To study the morphological development and histomorphometry of foetal and adult ovaries in Kano brown goats. Materials and Methods: Fifty-one foetal and fourteen adult ovaries obtained from slaughtered Kano brown does in Nsukka abattoir were used for this study. The ages of the adult does were determined by dentition and foetuses by crown rump length method. The foetal and adult ova...
