Effect of <strong>bolt</strong> velocity and diameter of a captive <strong>bolt</strong> <strong>gun</strong> on energy transfer (joule),<br />
To the animal´s head and the presence of Visual‐Evoked Responses in the brain<br />

VER´ s were measured as an index of brain function<br />
by way of electrocorticograms taken from electrodes planted into the<br />
brains of the cattle. The electrical wave values given indicate the brains<br />
ability to respond to external stimulus, which in this case were light<br />
flashes from a source 1 meter in front of the animal’s eyes.
