The types of sensors which receiving Brain Signal

In summary, the conversation is about designing a research experiment to study the effects of electricity on the brain. The person is looking for alternative sensors to collect brain signals, as they have already failed with EEG and do not have access to expensive equipment like MRI. Suggestions are made for using NIRS, an optical method that can be used on infants and is more portable than MRI. However, NIRS cannot fully replace fMRI as it can only scan cortical tissue.

Hi :)
I'm designing a research and need you guys's help :)
It's an experiment to finding out what happens in our brain when we are stimulated by electricity.

I have to collect the signals from brain, but not using EEG.
(I already failed once...:'( )
I've been thinking about MEG, but it dosen't seems bringing good result 'cause you know, electric/magnetic fields are so mutual..

So could you notice us if there are any other sensors which can collect brain signal??
(It's small experiment so enormous equipment like (f)MRI couldn't be used..)

Thank you a lot. :D Have a nice day :D

I'm sorry you are not finding help at the moment. Is there any additional information you can share with us?

Also there are optical methods ...

wikipedia.org/Optical_topography said:
NIRS can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., in branches of Cognitive psychology as a partial replacement for fMRI techniques. NIRS can be used on infants, and NIRS is much more portable than fMRI machines, even wireless instrumentation is available, which enables investigations in freely moving subjects. However, NIRS cannot fully replace fMRI because it can only be used to scan cortical tissue, where fMRI can be used to measure activation throughout the brain.

What are the different types of sensors that can receive brain signals?

There are several types of sensors that can receive brain signals, including electroencephalography (EEG) sensors, magnetoencephalography (MEG) sensors, functional magnetic resonance imaging (fMRI) sensors, near-infrared spectroscopy (NIRS) sensors, and transcranial magnetic stimulation (TMS) sensors.

How do EEG sensors receive brain signals?

EEG sensors use electrodes placed on the scalp to detect electrical activity in the brain. These electrodes pick up the electrical signals produced by the neurons in the brain and send them to a computer for analysis.

What types of brain signals can MEG sensors receive?

MEG sensors can receive both electrical and magnetic signals from the brain. These sensors are very sensitive and can detect even very small changes in brain activity.

What advantages do fMRI sensors have over other types of brain signal sensors?

fMRI sensors have the advantage of being able to detect changes in blood flow and oxygen levels in the brain, which can provide information about brain activity in specific regions. They also have a higher spatial resolution compared to other sensors.

What is the purpose of using NIRS sensors to receive brain signals?

NIRS sensors are often used in research studies to measure changes in blood flow and oxygen levels in the brain. They are also used in medical settings to monitor brain activity and detect abnormalities in brain function.
