Honeybees can remember reward-associated odors three days after a single learning experience.

Under constant darkness, Drosophila’s ability to form lasting memories is impaired.

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

The animals develop a new memory that overrides the fearful one by inhibiting the cells that encode the original memory.

Researchers have developed ways to manipulate neurons involved in a particular memory to make mice recall an experience or to remember something that never happened.

Juvenile birds learn the length of the sounds in a song from a false memory introduced via optogenetics, instead of from real interactions with a tutor bird.

Hear seals imitating human sounds and melodies.

Young zebra finches that receive feedback after they sing from a video of a fluffed-up female eventually develop more accurate tunes.

Male rodents exposed to nicotine had changes in sperm genome methylation and produced pups and grandpups with abnormal behavior.

By stimulating specific neurons in mouse brains, researchers demonstrate that memories from infancy are not lost, but merely difficult to access.

When it comes to tool making, the birds learn differently than humans.

As the years go by, seabirds such as gannets get better at foraging.  

Ecological challenges such as finding food and creating fire may have led the organ to become abnormally large, a new computer model suggests.

Moderate ultraviolet light exposure boosts the brainpower of mice thanks to increased production of the neurotransmitter glutamate.  

Researchers identified thousands of immature neurons in the brain region, countering a recent result showing little, if any, signs of neurogenesis.

Failure to produce evidence of neural precursor cells and immature neurons raises questions about the role of the process in learning and memory.

Researchers map learning-induced chromatin alterations in mouse brain cells, and find that many affect autism-associated genes.

Upping a gene’s expression in rat brains made them better learners and normalized the activity of hundreds of other genes to resemble the brains of younger animals.

A set of neurons in the brain’s central amygdala plays a key role in forming memories of aversive experiences, scientists find in mice.
