Human frontal lobes are not relatively large.
One of the most pervasive assumptions about human brain evolution is that it involved relative enlargement of the frontal lobes. We show that this assumption is without foundation. Analysis of five independent data sets using correctly scaled measures and phylogenetic methods reveals that the size of human frontal lobes, and of specific frontal regions, is as expected relative to the size of ot...
متن کاملHuman Frontal Lobes and AI Planning Systems
This paper presents an AI model of integrated planning and reaction based on neuropsychological theories of similar human behavior. The model forges a link between frontal lobe models and AI planning systems that can improve our understanding of situated planning through a combined perspective. This paper first sets the frontal lobes in context, and then summarizes the frontal lobe theories upo...
متن کاملFrontal Lobes and Memory
Casual observations of patients with focal frontal lobe lesions often reveal little if any cognitive impairment (Fuster, 1989; Hebb, 1945). At the same time, such patients display an assortment of cognitive deficits upon neuropsychological assessment (Janowsky et al., 1989c; Luria, 1980; Stuss & Benson, 1984). With respect to memory, focal frontal injury does not produce a severe amnesic disord...
متن کاملBroad and Narrow Conceptual Tuning in the Human Frontal Lobes
Previous work has implicated prefrontal cortices in selecting among and retrieving conceptual information stored elsewhere. However, recent neurophysiological work in monkeys suggests that prefrontal cortex may play a more direct role in representing conceptual information in a flexible context-specific manner. Here, we investigate the nature of visual object representations from perceptual to ...
متن کاملHuman rehearsal processes and the frontal lobes: PET evidence.
Our research is focused on working memory. This is a storage system that holds a limited amount of information for a brief time, with that information rapidly accessible and changeable from moment to moment. Such a system is essential for dealing with problems that require one to record features of a constantly changing environment, and to keep these features "on line" as they are used to guide...
