Working memory con be affected due to lesion in -
Answer- A. HypothalamusWorking memory stores items only as long as the information is in consciousness and is either being rehearsed (subvocally) or manipulated in some other fashion (i.e. rotated or integrated with existing information in semantic memory).Working memory is highly vulnerable to distraction and sometimes is even called working attention to emphasize the conscious and effoful processes that it entails.Lesions that disrupt the structure or function of the dorsolateral frontal or posterior parietal regions decimate working memory.
