Subject: Re: tramatic brain injury and 'photographic' auditory recall From: Diana Deutsch <ddeutsch(at)UCSD.EDU> Date: Tue, 29 Jul 2003 13:35:51 -0700Dear Jerry, Penfield and associates found that, on stimulation of certain regions in the temporal lobe, patients might 'hear' long segments of speech or music as though they were really occurring. There is a question, though, of whether these experiences constituted true or 'imagined' recall. From your description it's unclear whether your wife simply 'remembered' these conversations, or whether they appeared to be true recurrences (i.e., as though real sounds). I also wonder whether she 'replayed' conversations that had occurred before or after the injury. Diana Deutsch >My wife sustained a concussion 2 years ago.
