A "non-specific" thalamic nucleus has
diffuse projections
Kalat claims that cases like MM and PD (people who have sight restored after many years) indicates that

Suppose you suddenly become deaf in one ear. With practice, you would most likely be able to locate familiar sounds based on differences in
loudness
The highest frequency sounds vibrate hair cells the most
nearest the oval window
The concept that neurons refine their many conections based on which ones are most successful is known as
neural Darwinism
Which of these sequences accurately characterizes brain development?
none of these

whether it responds to lines in more than one location
