The Role of the Medial Prefrontal Cortex-Amygdala Circuit in Stress Effects on the Extinction of Fear

Neural Plasticity, 2007
Stress exposure, depending on its intensity and duration, affects cognition and learning in an adaptive or maladaptive manner. Studies addressing the effects of stress on cognitive processes have mainly focused on conditioned fear, since it is suggested ...

Functionally referential signals: a promising paradigm whose time has passed [PDF]

, 2012
Finding the evolutionary origins of human language in the communication systems of our closest living relatives has, for the last several decades, been a major goal of many in the field of animal communication generally and primate communication ...

Alternative farrowing systems: design criteria for farrowing systems based on the biological needs of sows and piglets [PDF]

, 2010
The construction of a suitable farrowing environment is a continuing dilemma: the piglet's needs must be matched with those of the sow and the farmer during the main phases that constitute farrowing: nest building, parturition and lactation. Difficulties

Ethological and Experimental Approaches to Behavior Analysis: Implications for Ecotoxicology [PDF]

Environmental Health Perspectives, 1996
Laboratory research in toxicology has progressed far beyond reliance on measures of mortality to make use of sophisticated behavioral preparations that can evaluate the consequences of sublethal toxicant exposure. In contrast, field studies have not evolved as rapidly.

The Impact of Disease on Behavior: Altering Behavior in the Course of Disease in Aging Cats

Pets
Associations between age-related diseases and behavioral alterations have been highlighted in previous studies. This study investigates the prevalence of diseases and behavioral changes in non-diseased and diseased senior cats before and after diagnosis,

Artificial neural networks as models of stimulus control [PDF]

, 1998
We evaluate the ability of artificial neural network models (multi-layer perceptrons) to predict stimulus-­response relationships. A variety of empirical results are considered, such as generalization, peak-shift (supernormality) and stimulus intensity ...
