The role of the pineal gland and its hormone-melatonin-as to the impact of vasopressin (VP) and/or oxytocin (OT) on the regulation of behavior was studied, the passive avoidance task being chosen as an experimental model. The results showed that VP facilitated the avoidance latency during the first retention trial; after pinealectomy, however, VP was ineffective in this regard. Intraperitoneal ...

Introduction: S100B is a protein released from astrocytes, which controls neuroglial relationship and probably plays a role in memory and synaptic plasticity. Study of the functional relationship between astrocytes and neurons is of great importance. The present study was conducted to evaluate the effect of S100B infusion into the CA1 region of the hippocampus, on memory performance in male ...

BACKGROUND AND PURPOSE The purpose of this study was to investigate the behavioral changes, in particular retention of memory, after focal cerebral ischemia in rats. METHODS Ischemia was produced by permanent occlusion of the left middle cerebral artery (MCA). For quantitative behavioral analysis, one-trial passive avoidance response and active avoidance response with the discrete lever-press...

A passive avoidance task was administered to 97 Caucasian and 110 African American offenders to (a) replicate prior research demonstrating poor passive avoidance in psychopathic individuals (Ps) with low anxiety, (b) compare the effects of anxiety, neuroticism, and fear in identifying subgroups of Ps and controls who differ in passive avoidance, and (c) reevaluate the generalizability of this f...

Two different measures of the retention of avoidance conditioning, frequently used in the investigation of retrograde anmesia (RA), were examined. Rats were given a single training trial on either passive or active avoidance in a conventional black-white discrimination apparatus and step•through latencies were recorded. Task sequence, footshock and hypothermia were experimentally varied across ...

The reinforcing effects of aversive outcomes on avoidance behaviour are well established. However, their influence on perceptual processes is less well explored, especially during the transition from adolescence to adulthood. Using electroencephalography, we examined whether learning to actively or passively avoid harm can modulate early visual responses in adolescents and adults. The task incl...
