Ketamine is an N-methyl-d-aspartate (NMDA) receptor antagonist that works by binding to the phencyclidine-binding site, thereby blocking influx of cations through the NMDA receptor channel. The use of ketamine to treat refractory status epilepticus in adults and older children is well documented. Maturational changes in neonatal NMDA and γ-aminobutyric acid receptor expression and function make NMDA receptor antagonists, like ketamine, attractive potential therapeutic agents for treatment of refractory seizures in the newborn. However, descriptions of its use in this age group are limited to two case reports. Concerns regarding potential ketamine-mediated neurotoxicity in the immature brain require further investigation.

Background: Arc is a synaptic immediate early gene that mediates two distinct pathways at excitatory synapses. Canonically, Arc accelerates endocytosis of AMPA receptors by direct binding to TARPgs and endocytic machinery and thereby contributes to mGluR-LTD. Arc also acts at recently potentiated synapses, where it is phosphorylated by CaMKII and binds NMDAR subunits NR2A and NR2B and recruits the PI3K adaptor p55PIK to assemble a signaling complex that activates AKT and inhibits GSK3β.

Background: Neurotransmitter receptors' contribution to Alzheimer's disease (AD) pathology development has been implicated by basic science studies but is yet to be fully established. Here, we incorporate receptor density maps into network spreading models to predict amyloid and tau patterns in AD, reflecting their potential roles in facilitating or impeding pathology production and connectivity-mediated spread.
Method: Amyloid-PET positive individuals from the Alzheimer's Disease Neuroimaging Initiative (ADNI) were divided into "early" (n = 119) and "late" (n = 69) pathology groups according to tau accumulation in the temporal cortex (Figure 1A).

Background: Lingual taste cells (LTCs) are taste buds' sensory cells that modulate gustation. This study's aim is to assess whether it can be successfully implanted in hippocampus, modulating learning and memory deficits observed in Alzheimer's Dementia (AD).
Methods: Retrospective trials on rodents i.
