The role of the amygdala central nucleus (CeN) in habit learning was assessed in two experiments. First, we examined the effects of bilateral lesions of the anterior CeN on an overtraining-induced lever press habit evaluated using an outcome devaluation protocol. Overtraining generated habitual performance and rendered sham lesioned rats insensitive to outcome devaluation, an effect that was al...

Neurons that fire in relation to licking, in the ventral part of the dorsolateral striatum (DLS), were studied during acquisition and performance of a licking task in rats for 14 sessions (2 h/d). Task learning was indicated by fewer errors of omission of licking and improved movement efficiency (i.e., shorter lick duration) over sessions. Number of licks did not change over sessions. Overtrain...

The possible effect of overtraining on interocular transfer of striated pattern discrimination was studied in Chinchilla rabbits. Over-training did not improve the low level of interocular transfer generally found in rabbits.

It is well documented that cardiorespiratory exercise, as well as muscular strength and endurance exercise, have a positive impact on a person’s health [1]. Many positive health benefits arise from moderate intensity exercise including decreased risk of heart disease, cancer, stroke, osteoporosis, and diabetes found in individuals who engage in regular physical activity [1]. The cardiovascular ...

This paper will discuss the phenomenon that, despite continuous or increased training, performance of an athlete is stagnant or even decreases without any obvious reason such as illness or injury. There is still no uniform term to describe this phenomenon. Part 1 of this review paper will give an overview of the differently used terms and definitions in this connection. Independent of whether m...

In language modeling we are always confronted with a sparse data problem. The Maximum Entropy formalism allows to fully integrate complementary statistical properties of limited corpora. The focus of the present paper is twofold. The new smoothing technique of LM-induced marginals is introduced and discussed. We then highlight the advantages resulting from a combination of robust features and s...

We examined the influence of extensive overtraining (75 trials) on the impact of neurotoxic basolateral amygdala (BLA) lesions on Pavlovian fear conditioning in rats. As we have shown previously, pretraining BLA lesions yielded severe deficits in the acquisition of conditional freezing in rats trained with either 1 or 25 conditioning trials. However, extensive overtraining (50 or 75 trials) mit...
