Researchers conducted a survey in which they were attempting to determine the whether the Classic Model is the best available theory, which only 2% of the scientists and medics reported as being the case. This model creates the idea that the Broca’s area and Wernicke’s area are connected via a single tract, so these are the only areas that can be deemed responsible for the overarching concept of language. According to modern findings, there are multiple tracts connecting the two regions—the uncinate fasciculus, the inferior front-occipital fasciculus, the middle longitudinal fasciculus and the inferior longitudinal fasciculus. There is also the belief that language function can be found in are...

This study shows that postpartum depression is not something tied to maternity, but rather hormonal changes and the biology of becoming a parent overall. C...
