PS267 Lecture Notes - Lecture 14: Neuroimaging, Thalamus, Animal Communication
Document Summary
Living classifications are typically based on visual or physical properties. Non-living things are usually classified based on functional characteristics. Some patients have difficulties with one type of classification but not the other. Warrington: aphasic patients with anterior portions of inferior temporal lobe damage = difficulty making living classifications (e. g. show picture of poodle = difficulty telling you that"s a poodle). Anterior portions of inferior + medial temporal lobe = difficulties making living classifications but no problem with non-living classifications. Aphasic patients with left frontal cortex damage and parietal cortex (very rare to have both) have difficulty making non-living classifications. Evidence supported by imaging work by martin et al. Takes undergraduate students and has them identify animals or describe animals = temporal gyrus activation. Then, have to answer questions about/identify tools = medial fusiform activation and left premotor area (left frontal). A lot of evidence that these structures are important for imagining movements.
