Crab N Back Vs. N Back

[hiphopo...@yahoo.com]

does anyone else here have experience playing crab n back. i have
been
in a rut lately and wanted to get back to the zen like state of mind
dual n back helped me achieve last year. so i've been playing a lot
of
crab position 6 back lately. i decided to start playing position n
back because my visual memory isn't nearly as good as my auditory
memory. i played four hours this wednesday night. i woke up feeling a
whole lot more focused and calm. i then played crab position 6 back
for three hours last night. it felt like my brain was heating up
behind my ear this morning. i believe my temporal lobe might be
regenerating. i am taking saffron as an antidepressant and this might
be the cause of the neurogenesis if it isn't from dual n back.
anyway,
i have been playing an aweful lot these last few days. i am feeling a
major improvement in intelligence but i am still pretty fatigued. i
wonder if i would be feeling this much improvement from position 6
back. i think crab n back might tax the working memory more because of
the
added manipulation of the sequences. does anyone here notice any
advantages to crab n back???
