Abstract

The aim of the study was to obtain a comprehensive map of cortical areas from where digestive sensations during intracerebral electrical stimulations (ES) in epileptic patients are elicited. Direct cortical ESs were performed in 339 medically intractable epileptic patients selected to presurgical evaluation using chronically stereotaxically implanted intracerebral electrodes and audio-video-EEG monitoring system. Digestive sensations were electrically induced on 723 different anatomical sites in 172 subjects (51%). According to the exclusion criteria, the final analysis includes 174 relevant stimulations evoked in 87 patients. The reported sensations referred predominantly to the upper part of the digestive tract including the epigastria and area over the periumbilical (n = 83; 48%), retrosternal (n = 17; 10%), pharyngeal (n = 31; 18%) and oral (n = 18; 10%) regions. The temporal pole (BA 38), hippocampus, amygdala and anterior cingulate cortex (ACC; BA 24/BA 32) were the typical anatomical locations connected with epigastric sensations. Retrosternal sensations were preferentially related to the ACC, while oro-pharyngeal sensations were most related to the suprasylvian opercular cortex and the insula. Cortical ESs are followed ...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.
