BRAIN DIFFERENCES. “Consistent with this suggestion, a number of studies have demonstrated anatomical differences in the inferior temporal lobe near regions related to grapheme and color processing in synesthetes, including increased fractional anisotropy (reflecting increased white matter or coherence of white matter), and increased gray matter volume; increased connectivity has been found in other forms of synesthesia as well.” https://lnkd.in/dfc7eju View in LinkedIn

CROSS WIRED. “Predicting this finding of “cross-activation” between grapheme and color regions, Ramachandran and Hubbard proposed that synesthesia results from an excess of neural connections between associated modalities, possibly due to decreased neural pruning between (typically adjacent) regions that are interconnected in the fetus.” https://lnkd.in/dfc7eju View in LinkedIn

LONG HISTORY. "Stem cell transplantation was pioneered in the 1950s using haematopoietic stem cells to repopulate the bone marrow in patients with cancers of the blood and bone marrow. Such is the success of this approach that an estimated 50,000 of these transplants are performed each year." https://lnkd.in/dxvp4xj View in LinkedIn

PREVENTABLE WORRY. "Some scientists and bioethicists fear the stem cells could create human eggs and sperm in the animals. To say the least, it's disconcerting to think about two mice making a human embryo...scientists could engineer the cells so that they were unable to form human brain cells, sperm or eggs. The animals could also be isolated or sterilized to prevent them from breeding." http://www.npr.org/sections/health-shots/2015/11/06/454693391/should-human-stem-cells-be-used-to-make-partly-human-chimeras View in LinkedIn

STEM CELL CHIMERAS. "Another concern is that the human cells could end up in the brains of the animals. That raises the prospect that "this will somehow give the animal a human consciousness, human mental capabilities.” http://www.npr.org/sections/health-shots/2015/11/06/454693391/should-human-stem-cells-be-used-to-make-partly-human-chimeras View in LinkedIn

SO ENDS this first of two weekends on synesthesia. When you buy a car, in general, the more complicated it is, the more there is that can malfunction. As engines go, the human body is about as complicated as they come, with millions of control points that can malfunction. In this regard, it is surprising that it works at all. It is likely that many functional faults do not let the zygote get beyond the starting blocks, and they simply vanish. View in LinkedIn

BELL CURVE. “Furthermore, evidence suggests that synesthesia may in fact be a graded phenomenon in the general population, creating the possibility that non-synesthetic relatives of synesthetes show endophenotypes of the condition, complicating the use of family linkage analyses.” https://lnkd.in/dfc7eju View in LinkedIn

GENDER NEUTRAL. “Previous studies examining the prevalence of synesthesia found a significant gender gap with a 6∶1 ratio of female synesthetes to males, leading to the suggestion that synesthesia was an X-linked condition. However, prevalence studies conducted using random sampling have shown an even distribution of synesthesia among the genders, suggesting the discrepancy was based on methodological flaws and self-report biases in earlier studies.” https://lnkd.in/dfc7eju View in LinkedIn
