thinking about #laterality,
my focus has always been on the dominant side,
in this case my hands,
seeing my off hand as less developed,
since the path of least resistance will 4 most things be just to develop / train one side.

took me a bit to realize, that theres a bunch of stuff my off hand can do,
that my dominant hand cant.

unsurprisingly these things are almost exclusively complementary to whatever the dominant side is doing.

whats also fun is that in #inlineskating im really only good / confident in rotating to the left, since the skateparks lines where i started out heavily favoured left rotation / turns

but in #snowboarding i lead with whichever side is the best 4 the situation and am equally good in leading with both sides

in snowboard school first thing they ask u 4 ur dominant side so they can adjust the bindings towards that side of the board but that never felt right to me

i tried both 'goofy' and 'standard' setups (snowboard slang 4 left or right dominant) but then finally on day 5 set the bindings symmetrically and never looked back

For the small number of people interested in cerebral lateralization, a little analysis showing that we need to measure it in individuals including a confidence interval around the estimate - if you do that, then what looks like bilateral processing turns out to be misleading: most people are lateralized but without bias to left or right.

A small rant about zombie ideas and the tendency to keep looking for modifications of study methods to avoid concluding that a null result is really null. http://deevybee.blogspot.com/2024/03/just-make-it-stop-when-will-we-say-that.html

Just make it stop! When will we say that further research isn't needed?

  I have a lifelong interest in laterality, which is a passion that few people share. Accordingly, I am grateful to René Westerhausen who ...

I haven't quite mastered threads on Mastodon, so will link to a Twitter thread - just for anyone interested in lateralisation of language and motor skills

Student Jack Grant developed some neat ways of assessing lateralisation of motor sequencing online using computer keyboard.

Thread on a lockdown project on language/motor #laterality that was headed up by PhD student Jack Grant. Preregistered study on relation between online #motor and #language #laterality indices (LIs). tldr: reliable but not related. https://t.co/LAVeA2q4or #neuropsychology

Organ #laterality of vertebrates involves asymmetric decay of Dand5 mRNA mediated by Bicc1, but how is this regulated? Structure-function analysis of #ciliopathy proteins ANKS3 & ANKS6 suggests a dual role in regulating binding of Bicc1 to mRNAs #PLOSBiology https://plos.io/45ilFZ7
Bicc1 ribonucleoprotein complexes specifying organ laterality are licensed by ANKS6-induced structural remodeling of associated ANKS3

Organ laterality of vertebrates is specified by accelerated asymmetric decay of Dand5 mRNA mediated by Bicaudal-C1 (Bicc1) on the left side, but how is this regulated? Structure-function analysis of the ciliopathy proteins ANKS3 and ANKS6 suggests a dual role in either inhibiting or promoting the binding of Bicc1 to its own transcripts and to client mRNAs.

For those interested in #asymmetry, this recent paper using Delphi method to try and reach consensus on assessment of #laterality is worth a read:

#Laterality

"Human right-handedness represents an unparalleled extreme among anthropoids and taxa displaying population-level handedness are rare. Species-level direction of manual #lateralization was largely uniform among non-human primates and did not strongly correlate with any of the selected biological predictors, nor with #phylogeny"

The evolution and biological correlates of hand preferences in anthropoid primates

Primate hand preference strength but not direction (left vs. right) generally reflects phylogeny and ecology at species level, but human handedness deviates markedly from all other species.
