Like sleep, a brief period of eyes-closed waking rest following encoding can improve memory. But in addition to quantitatively strengthening memory, sleep also qualitatively transforms memory. In one example of this effect, sleep has been r...

Habitual control of repeated behaviours is adaptive because it can allow routine behaviours to continue under conditions where cognitive capacity is limited or burdened. However, the impact that cognitive demand has on behavioural control h...

Responding appropriately to both internal and external factors to maintain homeostasis is key to survival in the dynamic environment we live in. Memory a is highly adaptive brain function which enables organisms to interact efficiently with...
The role of post-learning EEG theta/beta ratio in long-term navigation performance [0.03%]
关于后学习EEGtheta/beta比值在长期空间记忆中作用的一项研究

Memory consolidation processes have been shown to benefit from modulations in brain activity, particularly theta oscillations. Our previous studies showed that increases in post-learning Theta/Beta power ratio improves subsequent performanc...

Mammals experience negative emotions after the unexpected reduction in reward magnitude-called frustrative nonreward (FNR). The neurobiological mechanisms activated in response to unexpected reward downshift could shed light on loss-induced...

Age-related memory loss affects approximately 40% of the world's population after the age of 65 and is a significant risk factor for the development of dementia and Alzheimer's Disease (AD). Numerous studies have reported that late in life ...
The interval between conditional stimulus onset and unconditional stimulus onset, not training-to-test interval, determines patterns of immediate early gene expression in the anterior retrosplenial cortex [0.03%]
在前部回神回皮质中，条件性刺激和非条件性刺激之间的间隔，而不是训练与测试之间的时间间隔决定了立即早期基因表达的模式

Prior work has found that the retrosplenial cortex (RSC) is necessary for formation and retrieval of trace, but not delay, fear conditioning. However, more recently, others have demonstrated that activity in the retrosplenial cortex is nece...
The REM effect: How sleep stages influence learning strategies in complex reward-based decision-making [0.03%]

Model-free (MF) and model-based (MB) learning strategies are complementary decision-making processes used in evaluating choices with potential rewards. Disorders involving compulsive behaviours (e.g., substance use, gambling) are suggested ...

Biperiden (BIP), a muscarinic type 1 (M1) receptor antagonist, has been proposed as a pharmacological model for episodic memory impairment in mild cognitive impairment (MCI) and early stages of Alzheimer's disease (AD). Understanding the ef...

Gonadal sex steroid hormones regulate internal states (Gutierrez-Castellanos et al., 2022), social drive (Guthman and Falkner, 2022), perception of external cues (Li and Dulac, 2018), and learning and memory (Taxier et al., 2020). Fluctuati...
