Progress in the study of the neural mechanisms of prefrontal lobe damage and visual spatial working memory

Visual spatial processor is an important part of working memory, is mainly used for the storage of visual object and spatial information, responsible for producing, operating and maintaining the visual image, which plays an important role in social cognition and behavior. Working memory is a memory model proposed by the British psychologist Baddeley and Hitch in 1974, which refers to a limited memory system for temporary processing and storage of information. Frontal lobe injury become the common position of brain injury in clinic and various types of memory dysfunction has also become the most common clinical patients with frontal lobe damage trauma sequela. The research on the mechanism of memory dysfunction and cognitive paradigm has become a hot research topic in the domestic and international. Key words: Frontal lobe lesion; Memory; Brain injury
