Increased potassium currents were responsible for hyperactivity of CA3 neurons. When exposed to potassium channel blockers, the hyperactivity disappeared. However, when exposed to lithium, the drug not only reversed hyperactivity but reduced potassium currents at the same time. The findings strengthen the case that potassium currents play a role in bipolar disorder.
Researchers report boosting levels of osteocalcin in the blood may help reverse age related memory loss in mice.
Researchers identify a neural circuit that connects the hippocampus and the entorhinal cortex, which is responsible for encoding episodic memory.
Researchers report on the epigenetic effect of early life stress. In a new study, researchers reveal mice who experienced stress in the first few weeks of life showed deterioration in memory, learning and maternal behaviors. Behavioral changes were seen in their later offspring, regardless of sex.
Researchers were able to dampen hyperexcitability associated with seizure disorders in rodent models by inducing biochemical alterations with glucosamine, a dietary supplement.
A new study offers evidence of source memory in nonhuman animals.
Researchers discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can help explain our ability to remember and sort information. The newly discovered gatekeeper nerve cells, also called OLM-alpha2 cells, provide an explanation to how the flow of information is controlled in the hippocampus.
Participating in exercise improved synaptic pruning in mouse models of autism. The study also found microglia dependant synaptic pruning is impaired by maternal inflammation, which has been previously connected to the development of ASD.
