The dorsal hippocampus is crucial for mammalian spatial memory, but its exact role in item memory is still hotly debated. Recent evidence in humans suggested that the hippocampus might be selectively involved in item short-term memory to de...
Parallel acquisition of awareness and differential delay eyeblink conditioning [0.03%]
有关觉知和平行差分延迟眨眼条件反射的获得研究

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 conditionin...
Differential regulation of glutamic acid decarboxylase gene expression after extinction of a recent memory vs. intermediate memory [0.03%]
近期记忆和中期记忆消退后谷氨酸脱羧酶基因表达的调节不同

Extinction reduces fear to stimuli that were once associated with an aversive event by no longer coupling the stimulus with the aversive event. Extinction learning is supported by a network comprising the amygdala, hippocampus, and prefront...
Serotonin transporter knockout rats show improved strategy set-shifting and reduced latent inhibition [0.03%]
五羟色胺转运体敲除大鼠的认知灵活性增强及潜隐抑制减弱

Behavioral flexibility is a cognitive process depending on prefrontal areas allowing adaptive responses to environmental changes. Serotonin transporter knockout (5-HTT(-/-)) rodents show improved reversal learning in addition to orbitofront...
Kv4.2 knockout mice have hippocampal-dependent learning and memory deficits [0.03%]
Kv4.2基因敲除小鼠海马学习记忆损伤

Kv4.2 channels contribute to the transient, outward K(+) current (A-type current) in hippocampal dendrites, and modulation of this current substantially alters dendritic excitability. Using Kv4.2 knockout (KO) mice, we examined the role of ...
Distinctive roles for amygdalar CREB in reconsolidation and extinction of fear memory [0.03%]
CREB在杏仁体中参与恐惧记忆的再巩固和消退的特异性作用

Cyclic AMP response element binding protein (CREB) plays a critical role in fear memory formation. Here we determined the role of CREB selectively within the amygdala in reconsolidation and extinction of auditory fear. Viral overexpression ...

The performance of developing zebrafish in both classical and operant conditioning assays was tested with a particular focus on the emergence of these learning behaviors during development. Strategically positioned visual cues paired with e...
NMDA signaling in CA1 mediates selectively the spatial component of episodic memory [0.03%]
CA1中的NMDA信号传导选择性地介导情景记忆的空间成分
Ryan Place,Christy Lykken,Zachery Beer et al.
Ryan Place et al.
Recent studies focusing on the memory for temporal order have reported that CA1 plays a critical role in the memory for the sequences of events, in addition to its well-described role in spatial navigation. In contrast, CA3 was found to pri...
Rapid and persistent suppression of feeding behavior induced by sensitization training in Aplysia [0.03%]
敏化训练在海兔体内快速而持久地抑制摄食行为

Ama Acheampong et al.
In Aplysia, noxious stimuli induce sensitization of defensive responses. However, it remains largely unknown whether such stimuli also alter nondefensive behaviors. In this study, we examined the effects of noxious stimuli on feeding. Stron...
Mushroom bodies of the honeybee brain show cell population-specific plasticity in expression of amine-receptor genes [0.03%]
蜜蜂大脑中的蘑菇体通过胺受体基因的表达表现出细胞群体特异性的可塑性

Dopamine and octopamine released in the mushroom bodies of the insect brain play a critical role in the formation of aversive and appetitive memories, respectively. As recent evidence suggests a complex relationship between the effects of t...
