Retrieval constitutes a highly regulated and dynamic phase in memory processing. Its rapid temporal scales require a coordinated molecular chain of events at the synaptic level that support transient memory trace reactivation. AMPA receptors (AMPAR) drive the majority of excitatory transmission in the brain and its dynamic features match the singular fast timescales of memory retrieval. Here we provide a review on AMPAR contribution to memory retrieval regarding its dynamic movements along the synaptic compartments, its changes in receptor number and subunit composition that take place in activity dependent processes associated with retrieval. We highlight on the differential regulations exerted by AMPAR subunits in plasticity processes and its impact on memory recall.

Social networks are increasingly taking over daily life, creating a volume of unsecured data and making it very difficult to capture safe data, especially in times of crisis. This study aims to use a Convolutional Neural Network (CNN)-Long Short-Term Memory (LSTM)-based hybrid model for health monitoring and health crisis forecasting. It consists of efficiently retrieving safe content from multiple social media sources.

Background: Sorbs2 is a cytoskeletal adaptor protein that is expressed in hippocampal neurons, but its mechanistic role in these cells is not yet fully understood.
Method: We created two groups of mice for our study: whole-body Sorbs2-Knockout (KO) mice and Sorbs2-Flox mice, which had neuronal knockout via AAV-PHP.eB-hSyn1-Cre virus injection.

Background: Murine studies have identified blood proteins that influence brain aging, but translating these findings to humans remains challenging. We used an innovative approach to investigate whether genetically predicted blood levels of proteins linked to brain aging in animal models are associated with cognitive performance in individuals at risk of Alzheimer's disease (AD) [Figure 1].
Method: Through systematic review, we identified 13 circulating proteins with an aging/rejuvenating effect on the mouse brain.

Background: Automated speech and language analysis (ASLA) represents a powerful innovation for detecting and monitoring persons with or at risk for dementia. Given its cost-efficiency and automaticity, its impact can be vital for under-resourced communities, such Spanish-speaking Latinos. However, ASLA markers are understudied in this group and may differ from those established in widely studied populations (e.

Background: To examine whether walking speed is associated with executive function in patients with subjective memory decline.
Method: Patients were recruited from the Fourth People's Hospital of Chengdu, including 63 patients with subjective cognitive decline (SCD) and 23 patients with mild cognitive impairment (MCI). Each participant assess global function by the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment-Basic Scale (MoCA-B).
