Question

question 4 of 10
in stage 4 sleep, what type of brain waves do you have?

a. beta

b. spindle waves

c. delta

d. neural

Explanation:

In sleep stage 4 (now often combined with stage 3 as N3 in modern sleep research), the dominant brain waves are delta waves. Beta waves are associated with wakefulness, spindle waves occur in stage 2 sleep, and "neural" is not a type of brain wave related to sleep stages. So the correct answer is C. Delta.

Answer:

C. Delta
