Forgetting things appears to be a productive process and not a passive loss of information.

Researchers find that an increased heart rate can induce anxiety in mice, given the right context.

A study finds roflumilast can reverse sleep deprivation–induced amnesia in mice, hinting at pathways to treating memory loss in people.

Nine people with spinal injuries walked again after electrical stimulation, allowing researchers to pinpoint neurons likely underlying their recovery.

The Boston University neuroscientist wants to take the edge off traumatic memories by manipulating how they’re processed in the brain.

A study shows “sonogenetics” could be a useful new tool in neuroscience and other fields.

Signals from sweeteners and sugars are relayed from the gut to the brain by different neural pathways, a new study concludes.

Mice have neurons that connect to both eyes but only propagate the signal from one or the other, simplifying the information sent to the cerebral cortex.

This year’s winners are Dieter Oesterhelt, Peter Hegemann, Karl Deisseroth, Drew Weissman, Katalin Karikó, and David Baltimore.

Research in mice suggests that moderating nerve activity with drugs or electrical pulses could modify tissue immune responses, curtailing the chronic pain often associated with inflammatory conditions.

After receiving an intraocular injection of the gene for a light-sensitive protein, a 58-year-old man diagnosed with the neurodegenerative eye disease retinitis pigmentosa was able to locate objects on a table using engineered goggles.

The animals adopt the emotional state of their cagemates, and the parts of the brain engaged during the process are different for pain and fear, according to a new study.

Using optogenetics, scientists have simulated the sense of smell directly within the mouse brain to investigate the nature of olfactory perception.

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

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.

Flashing lights activate fly navigation neurons.

A new method helps neural stem cells form synaptic connections, thereby restoring lost brain function.

A new tool helps stem cells integrate with host neural circuitry after implantation in mice.
