Chlorpheniramine impairs spatial choice learning in telencephalon-ablated fish.
This work investigated the effect of the H1 receptor blockade in the forebrain of ablated Carassius auratus in a simple stimulus-response learning task using a T-maze test with positive reinforcement. The goldfish were submitted to surgery for removal of both telencephalic lobes five days before beginning the experiment. A T-shaped glass aquarium was employed, with two feeders located at the ex...
متن کاملVitamin D Deficiency Impairs Spatial Learning in Adult Rats
Background: Through its membrane and intracellular receptors, vitamin D regulates many vital functions in the body including its well known actions on musculoskeletal system. Growing body of evidences demonstrate that vitamin D undergoes some of behavioral aspects of neurocognition. The present study was designed to evaluate the effect of food regimens without vitamin D or with a supplement of ...
متن کاملTelencephalon ablation impairs goldfish allocentric spatial learning in a "hole-board" task.
The present work analyzes the involvement of telencephalon of goldfish in spatial strategies, using a procedure analogue to the hole-board task. With this aim, goldfish with sham operation or telencephalon ablation were trained to find a baited feeder within a twenty-five feeder matrix, which maintained stable spatial relationships relative to five peripheral landmarks. After training, differen...

متن کاملChlorpheniramine impairs functional recovery in Carassius auratus after telencephalic ablation.
We determined the effect of an H1 receptor antagonist on the functional recovery of Carassius auratus submitted to telencephalic ablation. Five days after surgery the fish underwent a spatial-choice learning paradigm test. The fish, weighing 6-12 g, were divided into four groups: telencephalic ablation (A) or sham lesion (S) and saline (SAL) or chlorpheniramine (CPA, ip, 16 mg/kg). For eight co...
