Obesity Impairs Short-Term and Working Memory through Gut Microbial Metabolism of Aromatic Amino Acids

Xavier Fernandez-Real Girona

The gut microbiome has been linked to fear extinction learning in animal models. Here, we aimed to explore the gut microbiome and memory domains according to obesity status. A specific microbiome profile associated with short-term memory, working memory, a ...

Subjective feeling of re‐experiencing past events using immersive virtual reality prevents a loss of episodic memory

Olaf Blanke, Andrea Serino, Bruno Herbelin, Robin Mange, Lucie Bréchet

Introduction: Personally meaningful past episodes, defined as episodic memories (EM), are subjectively re-experienced from the natural perspective and location of one's own body, as described by bodily self-consciousness (BSC). Neurobiological mechanisms o ...

Sensorimotor conflicts alter metacognitive and action monitoring

Olaf Blanke, Roy Salomon, Fosco Bernasconi, Nathan Quentin Faivre, Laurène Véronique Vuillaume

While sensorimotor signals are known to modulate perception, little is known about their influence on higher-level cognitive processes. Here, we applied sensorimotor conflicts while participants performed a perceptual task followed by confidence judgments. ...

Engram Excitement

Johannes Gräff, Zimbul Albo

Engram cells can encode and switch between multiple mnemonic functions, but how they intrinsically do so is unknown. Pignatelli, Ryan, and colleagues show that upon memory recall, the engram's excitability is transiently elevated, allowing its bearer to ad ...

Reactivation of Recall-Induced Neurons in the Infralimbic Cortex and the Basolateral Amygdala After Remote Fear Memory Attenuation

Johannes Gräff, Ossama Mohamed Salah El-Dien El-Sayed Ibrahim Khalaf

Whether the attenuation of traumatic memories is mediated through the suppression of the original memory trace of fear by a new memory trace of safety, or through an updating of the original fear trace towards safety has been a long-standing question at th ...

Stability of working memory in continuous attractor networks under the control of short-term plasticity

Wulfram Gerstner, Moritz Deger, Alexander Kevin Seeholzer

Continuous attractor models of working-memory store continuous-valued information in continuous state-spaces, but are sensitive to noise processes that degrade memory retention. Short-term synaptic plasticity of recurrent synapses has previously been shown ...

Capturing the spatiotemporal dynamics of self-generated, task-initiated thoughts with EEG and fMRI

Rolf Gruetter, João Pedro Forjaco Jorge, Lucie Bréchet

The temporal structure of self-generated cognition is a key attribute to the formation of a meaningful stream of consciousness. When at rest, our mind wanders from thought to thought in distinct mental states. Despite the marked importance of ongoing menta ...

Episodic memory decline in Parkinson' s disease: relation with white matter hyperintense lesions and influence of quantification method

Tobias Kober, Meritxell Bach Cuadra, Bénédicte Marie Maréchal

The relation of white matter hyperintense lesions to episodic memory impairment in patients with Parkinson's disease (PD) is still controversial. We aimed at evaluating the relation between white matter hyperintense lesions and episodic memory decline in p ...
