MATH 190 Lecture Notes - Lecture 32: Phosphene, Retrograde Amnesia, Thalamus
Document Summary
Cognitive processes (thought), behaviour & phenomenal experience are highly correlated. However, in some cases there can be dissociations btw the three. E. g. blindsight: dissociation btw subjective and objective measures dissociate. Toxic effects of alcohol & thiamine deficiency. Destruction of mammillary bodies, dorso-medial nucleus of thalamus & diffuse damage to frontal lobes. Anterograde amnesia: inability to form new ltm while stm stays intact (allows normal interaction in the moment) Yes, they are awake, responsive, able to converse, laugh & show emotion. But self is trapped in the past and unrelated to events & people of the present. Lost interaction btw current & stored info (according to weiskrantz this makes the commentary that underlies consciousness possible) Create no memory of a continuous self. Condition in which a person with a condition is unaware of having it (deficit of self-awareness) Part of their mind seems to know the facts while another part does not.
