Abstract

Here, we found that a single intrathecal (i.t.) administration of a protein kinase C (PKC) activator, phorbol 12,13-dibutyrate (PDBu), induced pain-like behaviors in mice. Furthermore, i.t.-administered PDBu caused the increased c-fos-like immunoreactivity in the parafascicular nuclei (PF), amygdala and cingulate cortex (CG), but not hippocampus. These findings suggest that the stimulation of spinal PKC results in an enhancement of neuronal activity in the PF, amygdala and CG associated with hyperalgesia.

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.

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.
