Congratulations to Drs. Williamson and Heilman on the publication of “Alterations of emotional reactivity following right temporal lobectomy,” which was published in Neurocase: The Neural Basis of Cognition.


To learn if a right temporal lobectomy altered a patient’s autonomic and cognitive responses to aversive and appetitive pictures, we investigated a man whose right anterior temporal lobe and amygdala had been resected to remove an arteriovenous malformation. This patient revealed unusually low self-reports of arousal with a lack of heightened skin conductance responses to aversive pictures. For pleasant pictures, his self-reports of arousal and his physiological responses were similar to healthy men. This patient’s responses are consistent with a bivalent model of emotional processing, with a right temporal lobectomy compromising the activation of his defensive action response system.
