Excitatory synaptic transmission in neonatal dorsal horn: NMDA and ATP receptors

Postnatal development sees a strong synaptogenesis in rat superficial dorsal horn. My studies show that synapses mediated by two excitatory neurotransmitters, glutamate and ATP, are functional since the very first postnatal days. Using an electrophysiological approach, the functional properties of two receptors activated by these neurotransmitters, glutamatergic NMDA and ATP ionotropic receptors, are described.
