The Notion headset can be used in combination with the Pendulum app to perform brain-training for sleep improvement.
The Notion comes in a modern casing containing a power adapter, USB cable, and spare electrodes.
The headset has 8 brain-sensors which read brain activity in the frontal, temporal and parietal regions of the brain. With the brain-sensors being spread out across several areas of the head, the headset provides a very comprehensive brain reading. When training with the Notion headset, you will learn to modulate brain activity in several regions and reach the optimal mental state for a good night of sleep.
