Behavioral outcomes are rarely certain, requiring subjects to discriminate between available choices by using feedback to guide future decisions. Probabilistic reversal learning (PRL) tasks test subjects' ability to learn and flexibly adapt...
Perisynaptic astroglial response to in vivo long-term potentiation and concurrent long-term depression in the hippocampal dentate gyrus [0.03%]
内侧前额叶长时程增强和同时出现的长时程抑制在海马齿状回的活体 peri-synaptic 星形胶质细胞反应

Perisynaptic astroglia provide critical molecular and structural support to regulate synaptic transmission and plasticity in the nanodomain of the axon-spine interface. Three-dimensional reconstruction from serial section electron microscop...
A Common Representational Code for Event and Object Concepts in the Brain [0.03%]

Events and objects are two fundamental ways in which humans conceptualize their experience of the world. Despite the significance of this distinction for human cognition, it remains unclear whether the neural representations of object and e...

People are remarkably self-focused, disproportionately choosing to think about themselves relative to other topics. Self-focus can be adaptive, helping individuals fulfill their needs. It can also be maladaptive, with self-focus a risk and ...
Age-related positivity bias in emotion recognition is linked to lower cognitive performance and altered amygdala-orbitofrontal connectivity [0.03%]
情绪识别中的年龄相关积极偏见与较低的认知表现和杏仁体-眶额皮层连接改变有关

Changes in emotion recognition are observed in ageing, in dementia, after brain lesions and as a function of mental health factors, such as depression. Older adults have been argued to show a 'positivity bias', which has been associated wit...
IGFBP2-Ceramides Pathway Mediates Divergent Myelin Breakdown in the PNS and CNS Following Injury [0.03%]
损伤后周围神经系统和中枢神经系统的髓鞘分解由IGFBP2- ceramide通路介导
Suchen Ma,Xinman Fu,Jinmeng Lyu et al.
Suchen Ma et al.
Following injury, the peripheral nervous system (PNS) exhibits remarkable regenerative capacity, whereas the central nervous system (CNS) has limited regenerative potential. This difference is partially attributed to distinct post-injury my...
Mechanisms of long term non-externally reinforced preference change: functional connectivity changes in a longitudinal functional MRI study [0.03%]
长期非外部强化的偏好变化机制：纵向功能磁共振成像研究中的功能连接改变

Behavioral change studies mostly focus on external reinforcements to modify preferences. Cue-approach training (CAT) is a paradigm that influences preferences by the mere association of stimuli, sensory cues, and a rapid motor response, wit...

Much research has focused on how perceptual, cognitive, and attentional processes modulate microsaccades, the small rapid gaze shifts that humans perform when at tempting to maintain steady gaze on a point. Yet the reasons why these fixatio...
