22 hours ago · In addition, the CD group also had lower volume in the thalamus (P = .0009), amygdala (P = .0014), hippocampus (P = .0031), and nucleus accumbens (P = .0052).
2 days ago · The hippocampus is a critical part of the brain that assists with memory processing, decision making, and conversion of short-term memories into long-term memories. Alzheimer’s disease, a common ...
3 days ago · The hippocampus is the neuroanatomic structure of the limbic system that is thought to be involved in consolidating learning. It is so named because it resembles a seahorse, which is a small structure deep within the brain. The hippocampal complex consists of the hippocampus proper and surrounding structures of the dentate gyrus and the ...
1 day ago · Aβ coverage in the hippocampus was significantly decreased in mice with RISP-cKO microglia (Fig. 4g) due to decreased plaque number (Fig. 4h); however, Aβ plaque size was not different between ...
1 day ago · One type of excitatory neuron in the hippocampus and four in the entorhinal cortex were significantly less abundant in people with Alzheimer’s than in people without. Individuals with depletion of those cells performed significantly worse on cognitive assessments. Moreover, many vulnerable neurons were interconnected in a common neuronal circuit.
1 day ago · Abstract. One of the most extensively studied members of the Ras superfamily of small GTPases, Rac1 is an intracellular signal transducer that remodels actin and phosphorylation signaling networks. Previous studies have shown that Rac1-mediated signaling is associated with hippocampal-dependent working memory and longer-term forms of learning ...
