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.
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.
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.
