Acute Ischemic Lesions Associated With Impairments in Expression and Recognition of Affective Prosody

Abstract: Purpose We aimed to: (a) review existing data on the neural basis of affective prosody;(b) test the hypothesis that there are double dissociations in impairments of expression and recognition of affective prosody; and (c) identify areas of infarct associated with impaired expression and/or recognition of affective prosody after acute right hemisphere (RH) ischemic stroke. Methods Participants were tested on recognition of emotional prosody in content-neutral sentences. Expression was evaluated by measuring v… Show more

“…Nevertheless, the few cases reported here are consistent with the proposal that processes involved in recognition of affective prosody depend on a ventral stream of processing – a sound to meaning network from superior temporal cortex to inferior and anterior temporal cortex – comparable to the ventral stream of processing of language in the left hemisphere (see also Wright et al, 2016 for additional preliminary evidence from stroke and Schirmer & Kotz, 2006 for a similar view based on functional imaging studies). That is, the two individuals with impaired access to acoustic features from speech (Cases 1 and 2) had right superior or anterior temporal lesions (also right anterior insula and anterior basal ganglia in Case 1).…”

“…This is consistent with the proposal that prosody expression depends on a dorsal stream of processing, from temporal cortex, to inferior parietal cortex, to frontal cortex – a “meaning to motor production” network comparable to a dorsal stream of processing of language in the left hemisphere (Kummerer et al, 2013; Poeppel & Hickok, 2004; Saur & Hartwigsen, 2012). Previous studies have indicated that the area most likely associated with the direct motor programming of affective prosody is right inferior-posterior frontal region, homologue of Broca’s area) (Ross & Monnot, 1980, Wright et al, 2016), ), also in the dorsal stream.…”

“…Investigaciones previas habían descripto fallas en los pacientes con lesiones del HD en la habilidad de comprensión de prosodia, tanto emocional (Dara, Bang, Gottesman, & Hillis, 2014;Harciarek et al, 2006;Kho et al, 2008;Rymarczyk & Grabowska, 2007;Wright et al, 2016) como lingüística (Parola et al, 2016;Pell, 1998), pero no habían examinado la existencia de diferentes patrones de rendimiento entre ellas. Estas evidencias permitieron documentar el compromiso de ambos tipos de comprensión prosódica en pacientes con lesiones del HD pero no fueron suficientes para fundamentar la existencia de independencia funcional entre prosodia emocional y lingüística.…”

“…Estas evidencias permitieron documentar el compromiso de ambos tipos de comprensión prosódica en pacientes con lesiones del HD pero no fueron suficientes para fundamentar la existencia de independencia funcional entre prosodia emocional y lingüística. Los patrones de disociación hallados en el presente trabajo pueden considerarse evidencia a favor de la independencia funcional entre la capacidad de comprender prosodia lingüística y emocional, tal y como habían sugerido varios investigadores (Belyk & Brown, 2014;Caballero, 2016;Joanette et al, 2008;Monrad, 1947;Ross & Monnot, 2008;Witteman et al, 2014;Witteman et al, 2011;Wright et al, 2016). Sin embargo, al no hallarse en nuestro grupo de pacientes con lesiones del HD el patrón de disociación doble en la comprensión prosódica, queda pendiente la realización de trabajos futuros en los que se indague estos patrones en un número mayor de pacientes y/o en otras poblaciones patológicas para apoyar la hipótesis de la independencia funcional con evidencias de doble disociación.…”
