Patterns of neural activity known as alpha waves, long thought to originate in the thalamus, may actually stem from a different brain region entirely.

Adult neurogenesis, already appreciated for its role in learning and memory, also participates in mental health and possibly even attention, new research suggests.

Cutting-edge microscopy is revealing how new neurons made in adult mice’s brains tap into existing neuronal connections.

Strategies to make lab animals forget, remember, or experience false recollections probe how memory works, and may inspire treatments for neurological diseases.

An extinct rodent relative of the capybara appears to have had a smaller brain-to-body ratio than similar species.

Some researchers and animal rights groups are amplifying their opposition to an assay that measures how long a rodent tries to stay afloat.

Machine learning could be the key to reducing the use of animals in experiments.

Young rats injected with a synthetic cannabinoid have more of the brain’s motivating dopaminergic signaling and fewer numbers of inhibitory neurons than controls.

Inflammation may be a strong contender for the connection between mom’s weight and children’s neurodevelopment, according to lab studies on animals.

The university is carrying out a review of animal handling in the now-closed lab of neuropsychologist Vedran Lovic.

These are the first known cases of individuals catching the virus from their pets in Canada or the U.S.

Researchers suspect the source of the toxins may be some of the state’s 50,000 or so marijuana farms.

Syrian hamsters and thirteen-lined ground squirrels are tolerant of chilly temperatures, thanks to amino acid changes in a cold-responsive ion channel. 

Male rodents given access to a running wheel early in life show increased neural activity and improved memory as adults.

Female rats fed a typical Western diet had offspring that were at higher risk of obesity than moms fed low-fat, high-grain meals.

Changes in diet can cause gut microbes to produce acetate, which in turn stimulates insulin secretion and obesity in rodents, scientists show.

Overwintering ground squirrels survive fluctuations in body temperature that would cause cardiac arrest in nonhibernators.

Visit the lab of Matthew Andrews at the University of Minnesota Duluth, who studies hibernating thirteen-lined ground squirrels to learn how their hearts manage extreme temperature fluctuations.

“Blind” rats fitted with a neuroprosthetic device that stimulates the brain when the animals turn their heads to the north or south can navigate mazes as well as sighted rats.
