Vision arises from a “bottom-up” process that transduces light into neural signals and a “top-down” process

Alzheimer’s disease currently affects more than 5.5 million Americans and is one of the costliest diseases to treat, according to the Alzheimer’s Association.

Giving opioids to animals to quell pain after surgery prolongs pain for more than three weeks and primes specialized immune cells in the spinal cord to be more reactive to pain, according to a new study by the University of Colorado Boulder.
