Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from learning-specific processing. Here, we trained volunteers on a visual task and measured the excitatory and inhibitory (E/I) balance in… Continue reading Complementary contributions of non-REM and #REM sleep to visual #learning

Generative Feedback Explains Distinct Brain Activity Codes for Seen and Mental Images
The relationship between mental imagery and vision is a long-standing problem in neuroscience. Currently, it is not known whether differences between the activity evoked during vision and reinstated during imagery reflect different codes for seen and mental images. To address this problem, we modeled mental imagery in the human brain as feedback in a hierarchical… Continue reading Generative Feedback Explains Distinct Brain Activity Codes for Seen and Mental Images
Association of Dual Decline in Memory and #Gait Speed With Risk for #Dementia Among Adults Older Than 60 Years
Dual decline in both memory and gait speed may characterize a group of older individuals at high risk for future dementia.. ..Participants were 60 years or older, had an initial gait speed of more than 0.6 m/s (ie, free of overt dismobility), with repeated measures of memory and gait speed before dementia diagnosis during a… Continue reading Association of Dual Decline in Memory and #Gait Speed With Risk for #Dementia Among Adults Older Than 60 Years
How #odor cues help to optimize #learning during sleep in a real life-setting
Effortless learning during sleep is everybody’s dream. Several studies found that presenting odor cues during learning and selectively during slow wave sleep increases learning success.. ..We (1) performed a field study of vocabulary-learning in a regular school setting, (2) stimulated with odor cues during the whole night without sleep monitoring, and (3) applied the odor… Continue reading How #odor cues help to optimize #learning during sleep in a real life-setting
Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal
Studies show that a single bout of exercise confers cognitive benefits. However, many individuals use psychoactive substances such as caffeine to enhance cognitive performance.. The objectives of this study were to compare the effects of acute moderate intensity aerobic exercise to caffeine on working memory (WM) and caffeine withdrawal symptoms (CWS). In Phase I, non-caffeine… Continue reading Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal
Extra virgin #olive oil improves synaptic activity, short‐term plasticity, #memory, and neuropathology in a tauopathy model
In recent years, increasing evidence has accumulated supporting the health benefits of extra virgin olive oil (EVOO). Previous studies showed that EVOO supplementation improves Alzheimer's disease (AD)‐like amyloidotic phenotype of transgenic mice.. ..At the end of the treatment, compared with control mice receiving EVOO displayed improved memory and cognition which was associated with increased basal… Continue reading Extra virgin #olive oil improves synaptic activity, short‐term plasticity, #memory, and neuropathology in a tauopathy model
