Physical exercise, IGF-1 and cognition A systematic review of experimental studies in the elderly

Dementia & Neuropsychologia
One of hypothetical mechanisms related to cognition is exercise-induced IGF-1. Objective: The aim of this study was to analyze the effects of exercise on IGF-1 levels and cognition in the elderly. Methods: The article searches were conducted on Pubmed,

Transcript diversification in the nervous system: A to I RNA-editing in CNS function and disease development

Frontiers in Neuroscience, 2012
RNA editing by adenosine deaminases that act on RNA converts adenosines to inosines in coding and non-coding regions of mRNAs. Inosines are interpreted as guanosines and hence, this type of editing can change codons, alter splice patterns, or influence ...

Episodic memory and self-reference via semantic autobiographical memory: Insights from an fMRI study in younger and older adults

Frontiers in Behavioral Neuroscience, 2015
Self-referential processing relies mainly on the medial prefrontal cortex (MPFC) and enhances memory encoding (i.e., Self-Reference Effect, SRE) as it improves the accuracy and richness of remembering in both young and older adults.

Seeing what you want to see: priors for one’s own actions represent exaggerated expectations of success

Frontiers in Behavioral Neuroscience, 2014
People perceive the consequences of their own actions differently to how they perceive other sensory events. A large body of psychology research has shown that people also consistently overrate their own performance relative to others, yet little is ...

Altered Biogenesis and MicroRNA Content of Hippocampal Exosomes Following Experimental Status Epilepticus

Frontiers in Neuroscience, 2020
Repetitive or prolonged seizures (status epilepticus) can damage neurons within the hippocampus, trigger gliosis, and generate an enduring state of hyperexcitability.

Quantification of mid and late evoked sinks in laminar current source density profiles of columns in the primary auditory cortex

Frontiers in Neural Circuits, 2015
Current source density analysis assesses spatiotemporal synaptic activations at somatic and/or dendritic levels in the form of depolarizing current sinks. Whereas many studies have focused on the short (

Validation and extension of the reward-mountain model

Frontiers in Behavioral Neuroscience, 2013
The reward-mountain model relates the vigor of reward seeking to the strength and cost of reward. Application of this model provides information about the stage of processing at which manipulations such as drug administration, lesions, deprivation states,

A patient with a long history of relapsing psychosis and mania presenting with anti-NMDA receptor encephalitis ten years after first episode

Dementia & Neuropsychologia
Anti-N-methyl- D-aspartate receptor (NMDAR) encephalitis is a recently discovered autoimmune disorder, in which antibodies target NMDARs in the brain, leading to their removal from synapses. Early in the disease course, patients often present with marked
