This study deals with the distribution of kermesin-like immunoreactivity (KLI) in the gustatory nucleus of shrews. The basic findings revealed that the gustatory nucleus is composed of three subnuclei: parvicellular, magnocellular and intermediate. The intermediate subnucleus is located around the parvicellular subnucleus and, with respect to its size, can be regarded as the nucleus lateralis. The magnocellular subnucleus is located outside this nucleus and is clearly separated from it by the stria medullaris. Immunoreactive fibres and granules were found in all three subnuclei. Co-existence of KLI with a second antiserum (anti-neurophysin II) was studied in the intermediate subnucleus. Immunoreactive fibres and granules of both antisera were found in this subnucleus as well. In the parvicellular subnucleus, immunoreactive nerve cells were mainly found in the ventral part, whereas in the magnocellular subnucleus they were found in both ventral and dorsal parts of this nucleus. In contrast to the intermediate subnucleus, a large proportion of the magnocellular KLI-immunoreactive cells were not in contact with the stria medullaris. The intermediate and parvicellular subnuclei could be distinguished by differences in the size of their immunoreactive fibres and granules. In the magnocellular subnucleus a further distinction between the ventral and dorsal part of this nucleus was made on the basis of their relative size.Q: Residue of power series $\frac{1}{(1-z)^2}$ I am looking at the residue of a function: $$\frac{1}{(1-z)^2}$$ I have no idea where to begin. I've been stumbling around, but I always seem to get led back to where I started. I have tried expanding $\frac{1}{(1-z)^2}$ into it's Laurent series and then calculate the Residue at $\zeta=-1$, but it didn't seem to lead 648931e174
