    Question for neurobiologists;

    Does anyone know what probes if there are any that exist that can be insert into humans without causing permanent damage, the areas I would be interested in measuring are the 'trigeminal nerves', ophthalmic nerves, the surrounding nerves, the cerebral, the parietal lobe and a few other places.

    If one wanted to measure these regions what can/would you suggest?

    Or would the methodology being less crude to scan the brain activity but can this be done in an open environment not within a machine that encapsulates the subject.

    Thanks

    The only probes currently available aren't for measurement purposes, but used in deep brain stimulation. Any adverse effects are typically reversible, they don't cause structural damage. As far as I'm aware, MRI is your best bet for imaging those areas. Open environment methods just won't get you the resolution available through MRI.


    I can never know I'm right, but I can know that I'm wrong.

    I have been studying biochemistry and techniques used in electrophysiology, I do know there are probes that have been used to study internal signals form external excitory stimuli.


    The problem is that of all the probes that I have currently researched cause substantial amount of damage that is irreparable.

    I did hear/read briefly of a micro diameter probe that causes no permanent damage but this is generally used to penetrate an inch or two into the subject.


    Thanks

    Studies have been done using probes inserted for deep brain stimulation, then between periods of stimulation the brain activity can be monitored at the site of the probes. That way a study can be piggybacked on the therapeutic insertion of the probes. Sorry I don't have a citation for that, I learned of the approach in conversation with a neurosurgeon friend.

    I heard something like that or read something about it and neurogenesis. The brain is the most interesting organ.
