<p>Alpha is a frequency of 8-12 Hz, responsible as the idling state of the brain. The generation of alpha is cortico-cortical processes (Stam, 2006, p. 49), as well as a cortico-thalamic process (DeRidder, 2014; Gunkelman, 2014). That means that alpha is generated from the cortex, as well as the thalamus. Although you are relaxed when in a predominantly alpha state, you are in the process of taking packets of data with each alpha wavelet (DeRidder, 2014).&nbsp;&nbsp;<br></p>
