Abstract

Norepinephrine has a strongly lateralized distribution in the human thalamus. In the pulvinar region the left hemisphere is rich in norepinephrine, whereas in the somatosensory input area the right hemisphere has a higher concentration of this catecholamine. Such naturally occurring left-right differences in concentration of a neurotransmitter represent a new aspect of hemispheric specialization.
