Abstract/Results: | ABSTRACT:
Astrocytes are being recognized as active elements concerning information flow in the brain, however their role in cognition is still unknown. In this study we aimed to understand the influence of astrocytic function in complex cognitive processes that depend on the medial prefrontal cortex (mPFC). The rationale consisted in analysing the cognitive performance of animals with induced glial pathology in the mPFC. This animal model was obtained by bilateral intracranial injections of L-a-aminoadipate to cause astrocyte ablation in Wistar-Han rats. Cognitive functions dependent on the mPFC, such as attention set-shifting and reversal learning of non-spatial working memory, were assessed by the attentional set-shifting task (ASST). Animals with mPFC-glial pathology showed no differences in learning how to perform the task, however they learnt faster the compound discrimination stages, when compared to the controls. Regarding the reversal learning stages, drug injected animals presented more difficulties than controls. Glial pathology seems to affect the function of neuro-glial networks, which may be translated in altered behavioural outputs.
