EEG Sleep Monitoring
Neuro Feedback EEG Sleep Monitoring Digital Health
When you think, dream, see and feel, your brain is constantly active, taking in all the information, compressing and reconnecting existing data, and integrating everything into a coherent experience. For you, this experience constitutes your reality.
Your brain is alive. Your brain shapes your perception of your surroundings, filtering or highlighting the objects and information that are most relevant to you. It creates its own story based on your thoughts, emotions, desires and experiences that ultimately drive your actions.
1 EEG activity of the brain to sleep monitoring
The brain is made up of billions of cells, half of which are neurons, and half of which help and facilitate the activity of neurons. These neurons are tightly connected by synapses, which are channels of inhibitory or excitatory activity.
Any synaptic activity produces a subtle electrical impulse called a postsynaptic potential. Of course, without direct contact with a single neuron, it is difficult to reliably detect its bursts. However, whenever thousands of neurons fire at the same time, they generate an electric field powerful enough to travel through tissue, bone and skull. Eventually, it can be measured on the surface of the head.
Think of this as the constant roar of a minor earthquake. On their own, each burst may be too small to detect, but if several of them occur at the same time, at the same place, and at the same rhythm, they add up to a large earthquake, even hundreds of miles away. can be detected outside.
2 What is EEG? How does it work for sleep monitoring?
An electroencephalogram (EEG) is a physiological method used to record the electrical activity of the brain through electrodes placed on the surface of the scalp. For faster application, the electrodes are mounted in an elastic cap similar to a shower cap to ensure data can be collected from the same scalp location in all subjects
Measure electrical activity (in volts) resulting from the synchronized activity of thousands of neurons
Provides excellent temporal resolution, allowing you to detect activity within cortical regions – even on sub-second time scales.
Since the voltage fluctuations measured at the electrodes are very small, the recorded data is digitized and sent to an amplifier. The amplified data can then be displayed as a sequence of voltage values.
The price difference in an EEG system is usually due to the number of electrodes, the quality of the digitization, the quality of the amplifier, and the number of snapshots per second the device can take (this is the sampling rate in Hz).
EEG usually has a high sampling rate and is one of the fastest-applied imaging techniques. A hundred years ago, the time course of the EEG was plotted on paper. The current system continuously displays voltage data on the screen in digital form.
3. How to interpret EEG data for sleep monitoring?
When EEG monitors the time course of electrical activity generated by the brain, it can explain which areas of the cortex are responsible for processing information at a given time:
This part of the brain is primarily responsible for processing visual information. EEG experiments with visual stimuli (videos, images) typically focus on the occipital region.
The parietal cortex is primarily responsible for motor functions and is active in self-referential tasks (for example, when we encounter objects or information that are important to us).
The side of the temporal cortex is responsible for language processing and speech production. During spatial navigation, the medial (inner) region is more active.
The frontal lobe of the human brain is enlarged compared to most other mammals. Basically, the frontal cortex is all about executive function: it helps us maintain control, plan for the future, and monitor our behavior. In addition to the regional characteristics of the origin of certain electrical activity, you can also analyze which frequencies are primarily driving the ongoing activity.
4. EEG Sleep Monitoring Hardware
The function of this EEG device collects the general activity signals in the brain, and at the same time, it can improve the mental capacity and explore the huge development potential of consciousness. The project has accumulated rich experience in neurofeedback EEG-SMT. The USB interface low-cost EEG device has been assembled, you only need a USB cable with a B-type connector and 5 electrodes to participate in the neurofeedback test.
The EEG detection equipment consists of two or more EEG amplifiers and a 6-channel signal capture board, which is connected to the PC through a standard serial cable. The standard-setting has two EEG channels.
