The basolateral amygdala (BLA) is critical for Pavlovian and instrumental emotional association learning. Pavlovian fear conditioning is accompanied by increased excitability of BLA neurons. Here we tested whether instrumental learning simi...

This study examined how agentic decisions in the absence of explicit rewards influence memory organization. Participants studied lists of items to assign as gifts to two characters-either choosing freely (Choice group) or following instruct...
Long-term dynamic profiles of cognitive kinases induced by different learning protocols [0.03%]
不同学习方案诱导的的认知激酶的长期动态谱型研究

Yili Zhang et al.
Learning is associated with activation of multiple protein kinases, but few details are known about the activation dynamics in response to different learning protocols. We addressed this issue by examining the long-term dynamics of kinases ...
Does recollection contribute to unitized associative memory? The roles of repetition learning and memory strength [0.03%]
重复学习和记忆强度对回忆式联想记忆的贡献作用是什么？

The ability to remember the relationship between unrelated events is a powerful cognitive function. When two unrelated stimuli are encoded in a condition of high level of unitization (LOU), the associative memory could be acquired with a st...
Influence of contextual exposure on memory strength and precision for inhibitory avoidance in male and female rats [0.03%]
上下文暴露对雄性和雌性大鼠抑制性回避记忆强度和精确度的影响

Aspen R Holm
Aversive associative learning paradigms such as inhibitory avoidance (IA) are frequently used to examine episodic-like memories in rodents. In IA, rodents learn to associate a context with a footshock, with testing for memory strength in th...
Maintenance of memory by negative feedback of synaptic protein elimination: modeling KIBRA-PKMζ dynamics in LTP [0.03%]
通过抑制性反馈维持记忆：KIBRA-PKMζ在长时程增强中的动态模型

Harel Z Shouval et al.
Long-term activity-dependent modifications of synaptic strength are a cellular substrate of learning and memory, but how long-lasting memory could be based on synaptic proteins that rapidly degrade and diffuse is unknown. Most current theor...
Medial orbitofrontal cortex activation reduces discrimination for threat in male rats [0.03%]
中隔 Orbitofrontal 大脑皮层激活可降低雄性大鼠对威胁的识别能力

Recognizing threats is crucial for animals to adopt appropriate behaviors. The orbitofrontal cortex (OFC) is essential for emotional regulation and cognitive flexibility. This study investigated the effect of medial OFC (mOFC) manipulation ...
Prospective and concurrent metamemory of familiarity and working memory by rhesus monkeys [0.03%]
猕猴对熟悉感和工作记忆的预期元认知和并发元认知
Jad Nasrini,Tara Dove-VanWormer,Robert R Hampton
Jad Nasrini
Monkeys sometimes accurately predict their memory accuracy, a form of metamemory. The memory signals that support this ability may differ between memory systems and depend on when memory judgments are made. Working memory requires active ma...
Differential impacts of advanced age and sex in age-related trace fear memory impairment in rats [0.03%]
衰老和性别在大鼠年龄相关痕迹恐惧记忆损伤中的不同影响
Payton K Robinson,Timothy J Jarome,Sydney Trask
Payton K Robinson
While cognitive function remains stable for majority of the lifespan, many functions sharply decline in later life. Women have higher rates of neurodegenerative diseases that involve memory loss, including Alzheimer's disease. This sex disp...
Sex and estrous cycle effects on stress-enhanced fear learning in Long-Evans rats [0.03%]

Individuals diagnosed with post-traumatic stress disorder (PTSD) are hyperresponsive to otherwise ordinary stimuli (e.g., loud noises or certain smells) long after a traumatic experience. At a preclinical level, this persistent effect of tr...
