Stimulus-dependent amygdala involvement in affective theory of mind generation

Abstract

Successful social interaction requires knowledge about another person's emotional states, represented in an affective theory of mind (ToM). This information can be acquired either directly or indirectly, i.e., by observing emotional facial expressions (EFE) or indirectly by inferring emotions through cognitive perspective taking. Therefore, it is of great interest how the function of the cortical ToM network and the limbic system in affective ToM depends on the presence of facial expressions. We addressed this question in a functional magnetic resonance imaging (fMRI) study. The experimental paradigm applied a well-established ToM cartoon task to test functional effects of EFE on the activation of the amygdala and the anterior ToM network during affective ToM judgments. During the task, 22 healthy participants had to judge the changes of the emotional state of the stories protagonist in the presence or absence of EFE. After quality control, 21 data sets entered the final analyses. The presence of EFE during affective ToM judgments was associated with shorter reaction times as well as increased activation of the right amygdala, most probably located in the basolateral nucleus (BLA), coincident with reduced activation of ToM-rela...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.
