Figure 6From: Non-peptidergic primary afferents are presynaptic to neurokinin-1 receptor immunoreactive lamina I projection neurons in rat spinal cord Quantification of IB4-positive boutons in direct apposition to the cell body and primary dendrites of NK-1r-IR lamina I spinoparabrachial neurons. Results are expressed in number of appositions from boutons per 100 μ of membrane length of NK-1r-IR cell. N = 6 animals.Back to article page
