Learning capacity

In the second place, normal consciousness can, at its natural limit, be so alluringly ecstatic as to induce a craving for more of the same. Lost elation calls for its restoration or enhancement via a stimulant booster. Such conscious state properties as creativity, sexual pleasure, and learning capacity can all be pumped up by bolstering or imitating the brain s own uppers. 

Extract of ginkgo leaf increases memory performance and learning capacity, deactivates toxic radicals, and improves blood flow.

With exposures to drugs severe enough to kill nerve cells or parts of cells, longterm, often permanent, deficits in sensory processes, motor function, behavior, learning capacity, and memory can occur. Since neurons do not reproduce, recovery of lost function occurs only if the remaining nervous system can take over the functions of the cells that were killed. Less severe exposures will modify function, often profoundly, until the drug is eliminated from the body. In most cases, normal behavior returns, and there may be no evidence of chronic consequences. With repeated exposures to some substances, however, the consequences may take on an irreversible quality. 

Two groups of female rats (n = 8) stemming from a strain with very low innate learning capacity were treated in the shuttle box at 100 trials daily for 5 days weekly. The rats were treated subcutaneously 60 min before training with saline and tetrabenazine, respectively. Detailed explanation in the text. CAR conditioned avoidance response EF escape failure. Significance in the performance between the saline-, and tetrabenazine-treated rats was evaluated by multi-factor analysis of variance (ANOVA) P < 0.05, P < 0.01, P < 0.001.

Extended exposure to low doses may have negative effects on the central nervous system, blood pressure, kidneys and D vitamin metabolism. In particular, children experience a reduction of growth rate and their learning capacity. 

In patients with moderate Alzheimer-type dementia, chronic treatment with selegiline (10 mg daily) had some beneficial effects such as improvements in congnitive functions, learning, alertness and task performance . These observations are in line with results obtained in rats chronically treated with selegiline, in which active treatment significantly improved the learning capacity as compared to saline treated controls. ... 

Furthermore, the K0SS project focuses on the interaction between students health, well-being, learning capacity and eating habits and sees the school meal as, not only a functional duty of supply but also, a forum for education. There is an understanding that the project empowers students by ... 

The least severe category would be characterized by deterioration in memory function and abihty to concentrate, physical fatigue, and irritabihty, while the second level would involve sustained mood and personality changes, as well as further deterioration of intellectual functions, including learning capacity. At least some of the effects of chronic exposure appear to persist well beyond the termination of the exposure, and may be permanent.

This chapter has introduced the construct of the recovery window in high-risk organizations and analyzed the 16-day window that ended in the breakup of the Columbia. Our analysis characterized the response to the foam threat as confirmatory in nature those involved discounted the risk, did not seek discordant data and perspectives, and failed to explore possible compensatory action. We have described an alternative - the exploratory response - and proposed that this pattern of behavior may provide a mechanism through which organizations can increase their collective learning capacity. 

Nociceptin (orphanin FQ) is a novel neuropeptide whose actions have yet to be completely elucidated. However, stimulation of the nociceptin receptor has been implicated in the modulation of many neurobehavioral processes, including pain, substance dependence, sexual behavior, anxiety, locomotor activity, learning capacity, memory, and adaptation to stressful stimulus [1-6]. Continued research in this area has the potential to lead to a new class of drugs for pain medicine and beyond. 

More than 300 papers have been published on the pharmacological properties of this extract [23]. Experimentally documented activity includes increased tolerance to hypoxia in brain tissue, improved learning capacity and memory, inhibition of platelet activator factor (PAF) [24], improved cerebral and peripheral circulation, neuroprotective effects [25], and reduction of retinal edema. Although all the constituents of the ginkgo extract are considered to contribute to the therapeutic effects, the ginkgo flavonoids are assumed to play an important role that is due to their free radical scavenging capacity.
