Experimental ablation: the removal or destruction of a portion of the brain of a laboratory animal; presumably, the functions that can no longer be performed are the ones the region previously controlled. Excitotoxic lesion: a brain lesion produced by intracerebral injection of an excitatory animo acid, such as kainic acid. Sham lesion: a placebo procedure that duplicates all the steps of producing a brain lesion except the one that actually causes the brain damage. Stereotaxic surgery: brain surgery using a stereotaxic apparatus to position an electrode or cannula in a speci ed position of the brain. Bregma: the junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery. Stereotaxic atlas: a collection of drawings of sections of the brain of a particular animal with measurements that provide coordinates for stereotaxic surgery.
