Distribution of nitric oxide synthase in the central nervous system of Macaca fuscata: subcortical regions
Abstract
The distribution of nitric oxide synthase-immunoreactive neurons was studied in the Macaca fuscata by immunohistochemistry using antiserum against nitric oxide synthase. In the macaque lower brainstem, many nitric oxide synthase-containing cell bodies were found in the gigantocellular and parvocellular reticular nuclei, the nucleus of the spinal tract of trigeminal nerve, the cochlear nucleus, the prepositus hypoglossi and the nucleus of the solitary tract. Many nitric oxide synthase-immunoreactive perikarya were observed in the laterodorsal-pedunculopontine tegmental nucleus complex of the macaque pontine and midbrain tegmentum. In addition, there were many highly immunoreactive cell bodies in the superficial layers of the inferior and superior colliculi. In the forebrain, numerous cell bodies were observed in the caudate nucleus, putamen, nucleus accumbens, nucleus of the diagonal band, anterior perforated substance and amygdaloid complex. Whereas most of these neurons were labeled highly intense for nitric oxide synthase, there were also many lightly labeled nitric oxide synthase-immunoreactive neurons in the substantia innominata, globus pallidus, ansa peduncularis and lateral hypothalamic nucleus. The present observation i...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.
Basal Ganglia
Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
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.
