Answer:
The correct order is: beta, alpha, theta and delta waves.
Step-by-step explanation:
Neuronal activity is an electrical activity that happens in our brain. When we talk about neurotransmitters, we are referring to molecules present in the brain that act as conductors of electrical activity between neurons. The fruit of which activity in the brain, it emits a series of waves. One produced in a state of consciousness and others in a state of relaxation, meditation or waking (during sleep). These frequencies are measured in the Hz (hertz) steps. They are called "brain waves".
We know of five major types of these brainwaves. Occurs when the brain has activity: Alpha; Beta; Gamma; Theta and Delta. During sleep, they appear in the following order: beta, alpha, theta and delta.
