In the NL every session is a complete Light/Sound composition. The two streams of stimulation are integrated both in design as well as neural function. There are even specific Brain Skills sessions such as Thalamus Cortex Synchronization (and others) that can assist in the Light-Sound brain signals to convert more efficiently into messages to the mind. The evoked neural electrical potential created by the composition is transmitted via neural pathways (audio signals via the medial geniculate; visual signals via the lateral geniculate) to the thalamus where audio and visual sensory information is processed. From the thalamus, the signal rich electrical activity is propagated through the cortical thalamic loop to the rest of the limbic system and cerebral cortex (Budzynski, et al., 2011; Collura & Siever, 2009).
