We tested whether N-methyl-D-aspartate (NMDA) receptors in the dorsal hippocampus (DH) are critical for the acquisition of trace fear conditioning using conditioned hypoalgesia (CHA), decrease in pain reactivity, as the conditioned response...
Cineradiographic (video X-ray) analysis of skilled reaching in a single pellet reaching task provides insight into relative contribution of body, head, oral, and forelimb movement in rats [0.03%]
高技能取食任务中单颗食物颗粒视频X射线分析为探究大鼠身体、头部、口腔和前肢运动的相对贡献提供了见解

Mariam Alaverdashvili et al.
The forelimb movements (skilled reaching) used by rats to reach for a single food pellet to place into the mouth have been used to model many neurological conditions. They have been described as a sequence of oppositions of head-pellet, paw...
A temporal analysis of the relationships between social stress, humoral immune response and glutathione-related antioxidant defenses [0.03%]
社会压力、体液免疫反应及谷胱甘肽相关的抗氧化防御之间的关系的时序分析

The relationship between trait stress-sensitivity, avoidance acquisition and perseveration of avoidance was examined using male Wistar-Kyoto (WKY) and Sprague-Dawley (SD) rats. Behavior in an open field was measured prior to escape/avoidanc...
Imaging of experience-dependent structural plasticity in the mouse neocortex in vivo [0.03%]
小鼠皮层神经元树突 spine 的功能依赖性结构可塑性光学成像研究

A Holtmaat et al.
The functionality of adult neocortical circuits can be altered by novel experiences or learning. This functional plasticity appears to rely on changes in the strength of neuronal connections that were established during development. Here we...
The role of the dorsomedial part of the prefrontal cortex serotonergic innervation in rat responses to the aversively conditioned context: behavioral, biochemical and immunocytochemical studies [0.03%]
与前额叶皮层背内侧部胆碱能投射有关的大鼠对有害条件化情境的反应：行为学、生化学和免疫细胞化学的研究

Małgorzata Lehner et al.
In this study we have explored differences in animal reactivity to conditioned aversive stimuli using the conditioned fear test (a contextual fear-freezing response), in rats subjected to the selective lesion of the prefrontal cortex seroto...
Hippocampal lesions in rats impair learning and memory for locations on a touch-sensitive computer screen: the "ASAT" task [0.03%]
