Immunocytochemical evidence for glutamatergic cortico-cortical connections in monkeys

Research output: Contribution to journalArticlepeer-review


Retrograde transport of horseradish peroxidase and immunocytochemical visualization of glutamate (Glu) were combined to investigate the neurotransmitter used by cortico-cortical neurons in the first (SI) and second (SII) somatic sensory areas of macaque monkeys. The majority of association and callosal neurons in SI and SII were immunoreactive for an antiGlu serum; evidence was therefore obtained in support of a role for Glu, or a closely related compound, as the synaptic transmitter used by cortico-cortical fibers.
