Effects Of Unilateral Ablation Research Articles

Physiological compensation in unilateral eyestalk ablated crayfish,Cherax quadricarinatus

The eyestalks of crustaceans contain neurosecretory cells involved in the regulation of molting. In crayfish, bilateral ablation results in increased molting frequency and weight gain whereas unilateral ablation typically has no effect on molting frequency and weight gain. The effects of unilateral ablation were examined in juvenile Australian freshwater crayfish, Cherax quadricarinatus. As observed for other crayfish species, molting frequency and weight gain of unilateral ablated crayfish were not significantly different from control (intact) crayfish. Survival of unilateral ablated crayfish, however, was reduced compared to controls and was likely due to stress associated with the surgical procedure itself. Using radiolabeling techniques, protein synthesis was determined for neural tissues from the remaining eyestalk of ablated crayfish and compared to protein synthesis of neural tissues from eyestalks of control, non-ablated crayfish. Protein synthesis of ablated crayfish neural tissues was significantly higher (ca. 45%) than protein synthesis of control neural tissues. Electrophoretic analysis (SDS-PAGE and autoradiography) further demonstrated that protein synthesis increased linearly for all proteins in the remaining eyestalk of ablated crayfish. Together, these results suggest that a compensatory response occurred in unilateral ablated crayfish allowing normal physiological functions, particularly those involved in regulating growth cycles, to be maintained.

Neglect following unilateral ablation of the caudal but not the rostral portion of medial agranular cortex of the rat and the therapeutic effect of apomorphine

The medial agranular cortex (AGm) of the rat is often considered analogous to the frontal eye field (FEF) of the monkey. However, recent anatomical, physiological, and behavioral evidence indicates that, while the caudal portion of AGm may indeed be an analog of the primate FEF, the rostral portion of AGm may be more similar to the primate supplementary motor area. The current study examined the effects of unilateral ablation of both the rostral and caudal components of AGm on the ability to orient to unilaterally presented stimuli. As expected, lesions of caudal but not rostral AGm resulted in a severe unilateral neglect of stimuli characteristic of rats with lesions of the entire rostral-caudal extent of AGm and of monkeys with FEF lesions. Caudal AGm operates also had more severe neglect than a group of rats from a previous study with larger AGm lesions which damaged the caudal portion of AGm to varying degrees. In addition, a second study showed the dopamine agonist apomorphine to have an acute dose-dependent therapeutic effect on the neglect resulting from caudal AGm ablation similar to that seen in animals with ablation of the entire rostral-caudal extent of AGm.
