The Significance of Three Errors in the First Chapter of Bhagavadgītā

The recognition of three errors in verses 1.10, 11, and 36 of Bhagavadgītā and the truth behind it is essential to grasp the beginning of the tread of thought developed by Vedavyāsa from the first to the last verse of the entire text spanning over 18 chapters. Generally, only the first error in verse 1.10 has received recognition, but as soon as the error is recognized there was attempt either to interpret the verse violating its syntax and semantics to make its meaning consistent with epic facts or to redraft the verse taking it as an error of a copyist, who has exchanged Bhīṣma with Bhīma and vice versa while copying the original. But, the attempt to remove the errors by interpretation or redrafting makes the interpreters ignore the significance of the errors in development in the argument and the readers become blind to the logic of thought as it is developed in Bhagavadgītā spanning over the entire text of Bhagavadgītā.

     

Risk dishabituation: in repeated gambling, risk is reduced following low-probability "surprising" events (wins or losses)

In path-dependent risk taking, like playing a slot machine, the wager on one trial may be affected by the outcome of the preceding trial. Previous studies have shown that a person's risk-taking preferences may change as a result of the preceding trial (win or loss). For example, the "house money effect" suggests that risk taking may increase after a win, whereas the "break even effect" posits that risk taking increases after a loss. Independent of those findings, a person's emotional state has been found to influence risk taking. For example, the "mood maintenance hypothesis" supports the notion that positive affect decreases risk taking, and related research finds that increased negative affect increases risk taking. Because winning and losing may influence one's emotional state, we sought to investigate how both previous outcomes, as well as a person's emotional responses to those outcomes, independently influence subsequent risk taking. To do this, data were collected using three simplified slot machines where the chance of winning each trial was set to 13%, 50%, and 87%, respectively. Evidence for the break even and house money effects were found on the 13% and 87% games, respectively. Likewise, emotional valence was found to predict risk taking on these two tasks, with emotional valence fully explaining the break even effect observed on the 13% game. In addition to these results, the present research revealed that risk taking is reduced following low-probability ("surprising") events (i.e., a win in the 13% condition or loss in the 87% condition). Dubbed "risk dishabituation," this phenomenon is discussed, along with its likely corresponding emotional experience--surprise.     

Impaired associative taste learning and abnormal brain activation in kinase-defective eEF2K mice

Memory consolidation is defined temporally based on pharmacological interventions such as inhibitors of mRNA translation (molecular consolidation) or post-acquisition deactivation of specific brain regions (systems level consolidation). However, the relationship between molecular and systems consolidation are poorly understood. Molecular consolidation mechanisms involved in translation initiation and elongation have previously been studied in the cortex using taste-learning paradigms. For example, the levels of phosphorylation of eukaryotic elongation factor 2 (eEF2) were found to be correlated with taste learning in the gustatory cortex (GC), minutes following learning. In order to isolate the role of the eEF2 phosphorylation state at Thr-56 in both molecular and system consolidation, we analyzed cortical-dependent taste learning in eEF2K (the only known kinase for eEF2) ki mice, which exhibit reduced levels of eEF2 phosphorylation but normal levels of eEF2 and eEF2K. These mice exhibit clear attenuation of cortical-dependent associative, but not of incidental, taste learning. In order to gain a better understanding of the underlying mechanisms, we compared brain activity as measured by MEMRI (manganese-enhanced magnetic resonance imaging) between eEF2K ki mice and WT mice during conditioned taste aversion (CTA) learning and observed clear differences between the two but saw no differences under basal conditions. Our results demonstrate that adequate levels of phosphorylation of eEF2 are essential for cortical-dependent associative learning and suggest that malfunction of memory processing at the systems level underlies this associative memory impairment.
