TL Stronger CTA in 14-3-3 Transgenics

From MagnetoWiki
Jump to: navigation, search

Test of stronger CTA in transgenic mice that overexpress R18 peptide, which blocks the ability of 14-3-3 to bind other proteins.

This is a follow-up (using the same mice) to experiment TK CTA in 14-3-3 Transgenics. The dose of LiCl was increased to 40 ml/kg 0.15M i.p.

Continued in experiments TM Stronger NaCl CTA in 14-3-3 Transgenics and TN Unconditioned Aversions in 14-3-3 Transgenics.
