Attentional deficits in Shank-3 deficient rat model Attention deficits are often associated with both PMS and ASD. Thus‚ we assessed performance in the attentionally demanding 5-choice serial reaction time (5-CSRT) task in which rats must respond quickly to briefly presented light cues (Fig. 1A). Both the Shank3 Het and KO rats learned the task and were able to reach baseline‚ similar to WT controls (criteria were accuracy rates higher than 80% for two consecutive days with omission rates lower than

Meningioma A Meningioma is a tumor of the central nervous system that develops from cells of the meninges (the Dura matter‚ arachnoid‚ and pia matter) and spinal cord. In most cases 90% of Meningiomas are benign (non-cancerous) and do not tend to spread out to the rest of the body or nervous system. These tend to grow at a very slow rate and usually show no symptoms until the tumor gets relatively large. This is due to the gradual compression of the brain over time. Although benign

Discuss the evolutionary explanations of functions of sleep. (24 marks) The evolutionary theories suggest sleep has evolved because it gives an animal a greater chance of survival when in a dangerous environment. They also suggest that sleep has evolved because it conserves energy and coincides with their eating habits. The evolutionary explanation (also referred to as the ecological approach) is based on the observation of animals in their natural environment. The evolutionary approach to
