Spermidine improves fear memory persistence
European Journal of Pharmacology, 2014 Persistence is the most characteristic attribute of long-term memory (LTM). For memory persistence, a second late event of consolidation, that occurs around 12h after the acquisition, is necessary. Although the N-methyl-d-aspartate (NMDA) receptor has been involved in the persistence of memory, whether endogenous modulators of the NMDA receptor ...

Diabetes‐Associated Cognitive Impairment: Pathophysiology and Emerging Therapies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Diabetes‐associated cognitive impairment (DACI) is a common yet underrecognized condition, manifesting along a spectrum from mild cognitive impairment to dementia. DACI encompasses patients who develop vascular dementia (VaD) or Alzheimer's disease (AD) with diabetes as a risk factor; however, in certain patients, particularly those lacking ...

, 2017 Urban problems have roots in much more abstract issues than only urban design. To understand this, we must cross the approaches of sociologists, politicians, historians, psychologists or criminologists, to name a few.

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Structural plasticity of synaptic connectivity in the adult hippocampal mossy fiber projection [PDF]
, 2013 The brain has the lifelong ability to change itself based on new experiences such as learning and memory. This so called neuronal plasticity is reflected in the brain by structural and functional modifications which underlie our ability to learn ...

Reserves, Injury Severity, and Outcomes in Traumatic Brain Injury: A CENTER‐TBI Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Reserve refers to the brain's ability to maintain function after an injury and strongly relates to traumatic brain injury (TBI) outcomes. This study examined (1) whether associations between pre‐injury reserve proxies and outcomes differed across injury severity categories, and (2) whether the impact of injury severity varied across ...

Fear renewal activates cyclic adenosine monophosphate signaling in the dentate gyrus
Brain and Behavior, 2019 Background Fear renewal, the context‐specific relapse of a conditioned fear after extinction, is a widely pursued model of post‐traumatic stress disorder and phobias. However, its cellular and molecular mechanisms remain poorly understood.
