Alicia was recently in a car accident. Since then, she cannot retain memories of events that occurred after the accident. However, she can recall events that took place before the accident. She recognizes her family and friends and important dates, such as her birthday and her marriage anniversary, but has to be constantly reintroduced to the new people in her life. Alicia has most likely sustained damage to her ________.
hippocampus

reticular formation
In which part of the eye are photoreceptors found?
retina
This binocular depth cue us based on the fact that when you look at an object, a slightly different picture of that object is displayed on each retina due to the different angles each eye is seeing it from.
retinal disparity
As part of a study in auditory perception, students were made to listen to a low-volume music track. When they first put on their headphones, they almost couldn't hear anything. But as they became more attentive, the sound gradually became clearer. This is an example of
