I don't normally cross reference information from PT but in this instance I feel it's necessary.
Many of you have probably seen the thread in question over there.
If not, here is the link. Pigeon Experiments
Just a little recap:
During a discussion I replied to a comment about performing an EEG (brain wave test) on a pigeon. My reply was in jest because it would be impossible to do this given what's involved. I felt it was a ridiculous comment to even make.
There was a reply to my post stating, in so many words, that they do perform EEG's on pigeons and a link was included.
I read the article and was horrified.
EEG's were in fact performed on pigeons, however for experimental purposes.
The test is used to record brain wave activity on a pigeon during flight.
This make me sick. And the manner in which the electrodes are 'implanted
' sickens me to the core.
I felt I needed to clarify my statement at PT as I was absolutely not condoning or joking about any type of treatment .
I had no idea this was going on.
The following was taken, in part, from the article:
Animal Handling and Electrode Implantation
Adult homing pigeons served as subjects for these experiments.
Varnish-covered nichrome electrodes (d = 150 µm) were used for intracranial EEG recording, and gold-covered watch screws for epidural EEG recording. Tetrodes were used for the action and field potentials recording. They were manufactured from 25 µm nichrome wire (A-M Systems) as described in Gray et al. (1995)Go and were mounted on a custom-made, manually operated, microdrive placed on the skull over thehippocampal formation.
Pigeons were anesthetized with a combination of xylazine (1 mg/kg body wt im) and ketamine (5 mg/kg body wt im) and placed in a stereotaxic apparatus (This is an instrument attached to the head, used to localize precisely an area in the brain by means of coordinates related to intracerebral structures). The skin on the dorsal surface of the skull was opened along the midline, and the appropriate number of holes was drilled in the skull to expose the dura (This is a tough fibrous membrane covering the brain and the spinal cord and lining the inner surface of the skull).
All electrodes were fixed to the skull with dental cement.

As with any experimental treatment on any animal, I feel this needs to be addressed.
A Pigeon's Prayer
Please watch over us while we fly,
Keeping us safe from the predators that share the sky.
If we become ill or injured in any way,
Please lead us to safety where we are welcome to stay.
