A high fat diet limits the birth and growth of new neurons in adult female, but not male, mice, according to new research published in eNeuro. Further research could inspire metabolism-based preventions and treatments for brain disorders.

Exposure to antidepressants during pregnancy and the first weeks of life can alter sensory processing well into adulthood, according to research in mice recently published in eNeuro.

A ketone-supplemented diet may protect neurons from death during the progression of Alzheimer's disease, according to research in mice recently published in JNeurosci.

Despite their common involvement in memory, the human cortex and subcortex display a distinct collection of gene signatures. The work recently published in eNeuro increases our understanding of how the brain creates memories and identifies potential genes for further investigation.

Rats susceptible to anhedonia, a core symptom of depression, possess more serotonin neurons after being exposed to chronic stress, but the effect can be reversed through amygdala activation, according to new research in JNeurosci.

A comparison of mouse Alzheimer's disease models shows changes in the number of cells and the genes they express remain consistent throughout all stages of the disease. The new research published in eNeuro could reveal new targets for disease intervention and therapies.

The drug ketamine decreases alcohol consumption in male, but not female, rats, according to new research published in eNeuro. The findings suggest that ketamine may be a viable treatment option for male patients with an alcohol use disorder.

Adolescent binge drinking modifies gene expression in a fashion that increases susceptibility to anxiety and alcohol use disorders in adulthood, according to research in rats recently published in eNeuro. Targeting the microRNAs responsible could be a new route for undoing the damage of alcohol use caused during adolescence.

Exposure to nicotine during development inhibits the function of neurons controlling the tongue, according to research in newborn rats recently published in eNeuro. This impairment may be a factor in sudden infant death syndrome in humans.

A drug commonly used to treat Type II diabetes abolishes the characteristic signs of nicotine withdrawal in rats and mice, according to new research published in JNeurosci. The finding may offer an important new strategy in the battle to quit smoking.
