Deciding advantageously in a complex situation is thought to require overt reasoning on declarative knowledge, namely, facts pertaining premises, options for action, and outcomes of actions that embody the pertinent previous experience. An alternative possibility was investigated: preceded by nonconscious biasing step uses neural systems other than those support knowledge. Normal participants patients with prefrontal damage decision-making defects performed gambling task which behavioral,...
Examination of temporal lobe structures from Alzheimer patients reveals a specific cellular pattern pathology the subiculum hippocampal formation and layers II IV entorhinal cortex. The affected cells are precisely those that interconnect with association cortices, basal forebrain, thalamus, hypothalamus, crucial to memory. This focal isolates much its input output probably contributes memory disorder in patients.
The somatic marker hypothesis proposes that decision-making is a process depends on emotion. Studies have shown damage of the ventromedial prefrontal (VMF) cortex precludes ability to use (emotional) signals are necessary for guiding decisions in advantageous direction. However, given role amygdala emotional processing, we asked whether also would interfere with decision-making. Furthermore, there might be difference between roles and VMF play To address these two questions, studied group...
When the landmark patient Phineas Gage died in 1861, no autopsy was performed, but his skull later recovered. The brain lesion that caused profound personality changes for which case became famous has been presumed to have involved left frontal region, questions raised about involvement of other regions and exact placement within vast territory. Measurements from Gage's modern neuroimaging techniques were used reconstitute accident determine probable location lesion. damage both right...
After bilateral ablation of orbital and lower mesial frontal cortices, a patient had profound changes behavior that have remained stable for 8 years. Although he could not meet personal professional responsibilities, his “measurable” intelligence was superior, therefore considered “malingerer.” Neurologic neuropsychological examinations were otherwise intact. CT, MRI, SPET revealed localized lesion the cortices. All other cerebral areas normal structure radioactivity patterns. Such...
A patient with selective bilateral damage to the amygdala did not acquire conditioned autonomic responses visual or auditory stimuli but declarative facts about which were paired unconditioned stimulus. By contrast, a hippocampus failed conditioning. Finally, both and hippocampal formation acquired neither conditioning nor facts. These findings demonstrate double dissociation of knowledge relative human hippocampus.
ABSTRACT— Recent advances in neuroscience are highlighting connections between emotion, social functioning, and decision making that have the potential to revolutionize our understanding of role affect education. In particular, neurobiological evidence suggests aspects cognition we recruit most heavily schools, namely learning, attention, memory, making, both profoundly affected by subsumed within processes emotion; call these emotional thought . Moreover, from brain‐damaged patients...
Although lesion and functional imaging studies have broadly implicated the right hemisphere in recognition of emotion, neither underlying processes nor precise anatomical correlates are well understood. We addressed these two issues a quantitative study 108 subjects with focal brain lesions, using three different tasks that assessed naming six basic emotions from facial expressions. Lesions were analyzed as function task performance by coregistration common space, statistical analyses their...
