The designated mechanism for selective attention is mediated by the right parietal lobe. * Declarative Memory involves the learning and remembrance of episodic memories like personal history, events, and experiences, and somatic memories like facts and information * Non-Declarative Memory otherwise known as non-consciousness is the memory for actions, behaviors, habits, skills, and outcomes. It is not a language memory but a motor memory. * Cerebellar Memory was originally thought to be related to only motor learning but is now believed to involve non-motor functions. Emotional Memory is mediated by the amygdala. The amygdala attach is positive or negative dispositions to stimuli in the absence of conscious recollection of the circumstances of the emotional experience. * Dementia is a disorder of the domain independent declarative memory network defined as the loss of past memories or Retrograde Amnesia, coupled with an inability to form new memories, which is Anterograde Amnesia, despite intact attentional networks. * A Temporary Domain Independent Dementia is found during complex partial seizures that persist for a time in the postical state, in postconcussive states, and in mild, posttraumatic brain injury states. * A Permanent Domain Independent Dysmnia may be seen after subarachnoid hemorrhage or moderate or severe post traumatic brain injury states; in carbon dioxide poisoning and other hypoxic or anoxic states; in Wernicke encephalopathy, viral encephalitis, and meningitis, and tumors, Alzheimer's and Pick disease. * A Pure Auditory or Visual Domain Specific Declarative Memory deficits manifests as an isolated agnosia. An isolated domain specific declarative memory deficit of tactile sensations rarely occurs clinically because selective attention would likely be affected as well. A temporary auditory, visual, or tactile pattern recognition, which is remote memory, deficit may appear as a result of seizure activity or a...
