The visual system of Hermissenda has been studied extensively as a site of cellular plasticity produced by classical conditioning. A one-trial conditioning procedure consisting of light paired with the application of serotonin (5-HT) to the exposed, but otherwise intact, nervous system produces suppression of phototactic behavior tested 24 h after conditioning. Short- and long-term enhancement ...

Text Dependent (TD) Speaker Recognition systems assume that the password to be uttered by the speaker is known to the system. As the password is known, the system can apply a password-specific model capturing the speaker dynamics well. This enables TD systems to perform better than textindependent systems. We present a variation of the TD systems, called text-conditioning, in which the password...

Background: GABAergic drugs can modulate the rewarding properties of morphine. The objective of this study was to evaluate the effects of isoniazid, as a GABAergic agent, on the rewarding effects of morphine. Methods: Eighteen groups of female mice (eight per group) were used in a conditioned place preference (CPP) study. On the conditioning phase of the CPP p...

Aiming at solving the problems of high compressor discharge temperature, pressure, insufficient cooling capacity, and reduced system efficiency in air-conditioning pure electric passenger cars summer temperature environment, this paper develops a low pressure economizer using principle quasi-two-stage compression cycle. The heat pump air conditioning air-supplemented car is set up to study its ...

The purpose of this study is to investigate the most effective blowing method underfloor air conditioning system from viewpoint comfort and ventilation performance using CFD simulation. In study, we simulated three types systems: floor radiation, floor-supply displacement air-conditioning, chamber. Then, was evaluated thermal environment PMV, age. As a result, radiation able maintain comfort. H...

Neonatal maternal separation alters learning and memory. Glucocorticoids also modulate adult learning and memory, and neonatal maternal separation alters forebrain glucocorticoid receptor (GR) concentrations. We used eyeblink classical conditioning to assess the effect of neonatal maternal separation on associative learning. We assessed delay eyeblink conditioning, GR expression, and total neur...

A basic goal in the neurosciences is to understand the cellular mechanisms underlying associative learning. The 2 major forms of associative learning are classical conditioning and operant conditioning. In recent years considerable progress has been made towards a cellular analysis of classical conditioning in a number of different preparations. In contrast, the cellular mechanisms underlying o...

There is considerable debate about whether differential delay eyeblink conditioning can be acquired without awareness of the stimulus contingencies. Previous investigations of the relationship between differential-delay eyeblink conditioning and awareness of the stimulus contingencies have assessed awareness after the conditioning session was finished using a post-experimental questionnaire. In...

The mu opioid receptor may constitute a critical component of a negative feedback system that regulates Pavlovian fear conditioning. We investigated context fear conditioning acquisition and expression in mu opioid receptor knockout mice (on an inbred, C57 genetic background). We discovered that the mu receptor knockout results in an unexpected and significant deficit in context fear acquisitio...
