The emotional behavioral aspects and the interaction between the changes of the polyamine contents and muricide response in thiamine deficient rats were investigated. In the thiamine deficient group, there was evidence of muricide and such increased progressively with advanced thiamine deficient feeding. This muricide was characteristic in the following respects; 1) the killer-rats did not eat but only kill a mouse and it was quite difficult to remove a sacrificed animal from the cage. 2) they bit at random into any body region of the mouse. 3) the killer-rats did not bite inanimate objects such as nails nor chalk. 4) the muricide induced by thiamine deficiency could not be suppressed by a single injection of thiamine HCl. On the 30th day of the experimental feeding, both spermidine and spermine levels in the brain of the thiamine deficient group decreased significantly as compared to the control and the pair-fed groups. Both spermidine and spermine levels were reversed to the control levels with a intraperitoneal administration of thiamine. There were no significant differences in spermine and spermidine levels between the killer-rats and non-killer-rats in the thiamine deficient group.

Exercise has been shown to improve cognitive functioning in a range of species, presumably through an increase in neurotrophins throughout the brain, but in particular the hippocampus. The current study assessed the ability of exercise to restore septohippocampal cholinergic functioning in the pyrithiamine-induced thiamine deficiency (PTD) rat model of the amnestic disorder Korsakoff Syndrome. After voluntary wheel running or sedentary control conditions (stationary wheel attached to the home cage), PTD and control rats were behaviorally tested with concurrent in vivo microdialysis, at one of two time points: 24-h or 2-weeks post-exercise. It was found that only after the 2-week adaption period did exercise lead to an interrelated sequence of events in PTD rats that included: (1) restored spatial working memory; (2) rescued behaviorally-stimulated hippocampal acetylcholine efflux; and (3) within the medial septum/diagonal band, the re-emergence of the cholinergic (choline acetyltransferase [ChAT+]) phenotype, with the greatest change occurring in the ChAT+/nestin+ neurons. Furthermore, in control rats, exercise followed by a 2-week adaption period improved hippocampal acetylcholine efflux and increased the number of neurons co-expressing the ChAT and nestin phenotype. These findings demonstrate a novel mechanism by which exercise can modulate the mature cholinergic/nestin neuronal phenotype leading to improved neurotransmitter function as well as enhanced learning and memory.
