The concept that neurotransmitter released from a neurone may feed back and influence the excitability of the same neurone has been suggested by a variety of evidence. Anatomical studies have shown that axon collaterals can arborize among the dendrites of the parent neurone1–7, suggesting a direct feedback via axon collaterals. In addition, the dendritic release of dopamine from substantia nigra neurones has suggested that dopamine may exert a direct feedback inhibition of these neurones8,9… CONTINUE READING
