Abstract

For the first time the model of secondary contractures of facial nerves was used to study by long-term sterotaxic implanted electrodes the state of the cortex, amygdal complex, reticular formation of the middle brain, reticular nuclei of the pons and nuclei of the facial nerves. The experiments were accomplished on 31 rabbits. The experiments confirmed a close functional connnection of the VII pair of cranial nerves with the limbico-reticular complex. In secondary contracture there were factors facilitating the influence of pons reticular structures on the deficient system the facial nerve--facial muscles. The achieved data are used to explain the origination of the main symptom of secondary contractures--a stable increase of the muscular tone.

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.
