Introduction
Your brain consists of billions of cells. Half of these cells are neurons, while the other half help facilitate neuron activity. These neurons are solidly interconnected through synapses, which act as inhibitory or excitatory activity gateways. Any synaptic activity activates a subtle electrical impulse known as postsynaptic potential.
A single neuron’s burst is challenging to detect without direct contact. But when thousands of them fire in sync, they trigger an electric field robust enough to spread via skull, bone and tissue. Eventually, a portable EEG cap solution can measure the electrical signals that the brain produces.
An EEG cap solution from a top-rated provider can analyse the electric signals and help diagnose several conditions, including the following:
- Head injuries
- Brain tumours
- Sleeping problems
- Dizziness
- Headaches
- Seizures
How Does an EEG Cap Work?
An EEG cap is a device that records the brain’s electrical signals, specifically the neurons’ postsynaptic potentials. The device manages to capture and record these electric signals via electrodes connected to an individual’s scalp, beneath the dura mater, or on the cortex. EEGs are based on the volume conduction of ionic current theory via non-empty extracellular space.
The recording is achieved by placing microelectrodes on the scalp. In order to create a perfect contact, there must be some abrasion using a conductive gel. The measured electroencephalogram activity is the entire synchronous activity amount in the area below the EEG cap electrode that has a similar approximate vertical orientation to the scalp in question.
The EEG cap solution detects the summed ionic currents of pyramidal neurons beneath each individual macro electrode and represents them as voltage differences across the low-resistance extracellular space. By doing so, EEGs enable researchers to record electrical impulses of the brain and observe changes in them. High-quality EEG cap solutions have two vital features that help with recording.
They can make nonstop recordings with split-second accuracy. Also, they can show a person’s general conscious state, such as awake, anaesthetised or asleep, because each state is connected to a specific EEG pattern.
Where Can You Find Top-Rated Portable EEG Cap Solutions?
If you’re after the best solution, you should look for a top-rated provider with BCI solutions based on EEG. Solutions from such a provider come with high-quality features, including dry-contact EEG electrodes, compact form factor and wireless connection.
It doesn’t matter what you want to use your portable EEG cap solution for; you should be sure to partner with a leading provider with a proven track record.
