Altered potassium levels in neurons may cause mood swings in bipolar disorder

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.

Exercise fine-tunes brain’s connections, eases autism spectrum disorder in mouse model

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.

A detailed drawing of the hippocampal formation is shown.

Quick thinking? It’s all down to timing

A pairing of presynaptic and postsynaptic activity in a population of hippocampal neurons can reduce the required number of synaptic plasticity evoking events. When spikes occur within ten milliseconds of each other, synapses strengthen for up to four hours.

Childhood Stress Affects Behavior of Offspring: Mouse Study

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.

Previous Motherhood Could Affect Hormone Therapy’s Ability to Prevent Memory Loss

A new study reports mother rats who received hormone replacement therapy responded worse to memory and spatial learning tasks than those who had not given birth. Researchers suggest a woman's reproductive history could impact how the brain responds to hormones later in life.
