Pavlovian phenomena in conditioned acceleration: Spontaneous recovery

Interdependence of measures in pavlovian conditioned freezing.

Pavlovian conditioned freezing is an intensively utilized paradigm that has become a standard model of memory and cognition. Despite its widespread use, the interdependence among each measure commonly reported in fear conditioning studies has not been described. Using mice, we examine the relationship of each common freezing measure (Training Baseline, Post-Shock freezing, Contextual Fear, Tone...

Pavlovian Conditioned Approach Training in Rats.

Cues that are contingently paired with unconditioned, rewarding stimuli can acquire rewarding properties themselves through a process known as the attribution of incentive salience, or the transformation of neutral stimuli into attractive, "wanted' stimuli capable of motivating behavior. Pavlovian conditioned approach (PCA) develops after the response-independent presentation of a conditioned s...

Temporally Specific Extinction of Pavlovian Conditioned Inhibition

Facilitation of Pavlovian conditioned cardiodecelerations following preshock in immobilized rats.

WILSON, L. M., J. R. WILSON AND L. V. DICARA. Facilitation of Pavlovian conditioned cardiodecelerations following preshock in immobilized rats. PHYSIOL. BEHAV. 15(6) 653-658, 1975. Two experiments are reported that examine the effects of unsignalled, inescapable prior shock exposure (PSE) on shock-motivated Pavlovian conditioned heart rate (HR) decelerations in rats. Both studies involved 2 CS-...

PARTICLE ACCELERATION PHENOMENA IN ASTROPHYSICAL PLASMASPulsed Acceleration in Solar

We study the nonlinear dynamics of particle acceleration in solar ares by analyzing the time series of various quasi-periodic radio signatures during ares. In particular we present the radio and hard X-ray data of 3 ares which support the following tentative conclusions: 1) Particle acceleration and injection into magnetic loops occurs intrinsically in a pulsed mode (with a typical period of 1-...
