bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

The role of raphe nucleus (R.N) and serotonin in some behaviors such as sleep, cognition, mood, and memory has previously been reported. The median raphe (MR) nucleus is a major serotonin-containing cell group within the brainstem and is one of the main sources of projections to the septum and hippocampus. The hippocampus is widely believed to be essential for context-conditioning learning. Mor...

Some of the previous studies show that children with SLD have deficits in visual processing and working memory. Hence, the aim of this research was to investigate problems of visual working memory based on behavioral neuroscience method, using an eye tracker device. The method of present study was ex-post facto study. The participants included couple of twelve children with SLD (mean age=10.92)...
