Social insects possess remarkable learning capabilities, which are crucial for their ecological success. They also exhibit interindividual differences in responsiveness to environmental stimuli, which underlie task specialization and divisi...
Focal uncaging of GABA reveals a temporally defined role for GABAergic inhibition during appetitive associative olfactory conditioning in honeybees [0.03%]
谷氨酸焦光解禁解释釋蜂膠在蜜蜂食欲联结式嗅觉条件反射过程中GABA能抑制的时空定义作用

Throughout the animal kingdom, the inhibitory neurotransmitter γ-aminobutyric acid (GABA) is a key modulator of physiological processes including learning. With respect to associative learning, the exact time in which GABA interferes with ...
Steroid hormone (20-hydroxyecdysone) modulates the acquisition of aversive olfactory memories in pollen forager honeybees [0.03%]
蜕皮甾醇激素（20-羟基ecdysone）调节花粉采集工蜂的厌恶型嗅觉记忆形成
Lisa H Geddes,H James McQuillan,Alastair Aiken et al.
Lisa H Geddes et al.
Here, we examine effects of the steroid hormone, 20-hydroxyecdysone (20-E), on associative olfactory learning in the honeybee, Apis mellifera. 20-E impaired the bees' ability to associate odors with punishment during aversive conditioning, ...
Temporal dynamics of recovery from extinction shortly after extinction acquisition [0.03%]
暂时性消退获得后的短期恢复动力学规律研究

Georgina E Archbold
Evidence suggests that extinction is new learning. Memory acquisition involves both short-term memory (STM) and long-term memory (LTM) components; however, few studies have examined early phases of extinction retention. Retention of auditor...
Schema-driven facilitation of new hierarchy learning in the transitive inference paradigm [0.03%]

Prior knowledge, in the form of a mental schema or framework, is viewed to facilitate the learning of new information in a range of experimental and everyday scenarios. Despite rising interest in the cognitive and neural mechanisms underlyi...
Reconsolidation may incorporate state-dependency into previously consolidated memories [0.03%]
重新巩固可能将先前巩固的记忆中的状态依赖性纳入其中
Rodrigo O Sierra,Lindsey F Cassini,Fabiana Santana et al.
Rodrigo O Sierra et al.
Some memories enter into a labile state after retrieval, requiring reconsolidation in order to persist. One functional role of memory reconsolidation is the updating of existing memories. There are reports suggesting that reconsolidation ca...
Hippocampal contribution to vector model hypothesis during cue-dependent navigation [0.03%]
海马体在基于线索的空间导航中的矢量模型假设贡献研究

Mairead Diviney
Learning to navigate toward a goal is an essential skill. Place learning is thought to rely on the ability of animals to associate the location of a goal with surrounding environmental cues. Using the Morris water maze, a task popularly use...
The role of contingency awareness in single-cue human eyeblink conditioning [0.03%]
单线索的人类眨眼条件作用中的应变意识的作用
Gabrielle Weidemann,Erin Best,Jessica C Lee et al.
Gabrielle Weidemann et al.
Single-cue delay eyeblink conditioning is presented as a prototypical example of automatic, nonsymbolic learning that is carried out by subcortical circuits. However, it has been difficult to assess the role of cognition in single-cue condi...

Heather M Holden et al.
Young and nondemented older adults completed a visual object continuous recognition memory task in which some stimuli (lures) were similar but not identical to previously presented objects. The lures were hypothesized to result in increased...
Mice overexpressing type 1 adenylyl cyclase show enhanced spatial memory flexibility in the absence of intact synaptic long-term depression [0.03%]
过表达型一腺苷酸环化酶的小鼠在不存在完整突触长时程抑制的情况下表现出增强的空间记忆灵活性
