Abstract

An immunocytochemical double-staining method was applied in order to study the co-localisation of nitric oxide synthase (NOS) with three calcium-binding proteins, calbindin D28k (CB), calretinin (CR) and parvalbumin (PV) in the claustrum of the rat during the first 4 months of life (postnatal days: P0–P120). The co-localisation of NOS/PV and NOS/CB is reported. These neurons fall into the category of non-pyramidal cells. Double-labelled NOS/CB neurons are observed in the claustrum starting from P4, whereas double-labelled NOS/PV neurons are observed from P14 onwards. The percentages of double-labelled neurons increase in relation to the age. Double-labelled NOS/CB and NOS/PV neurons, although they do not constitute a numerous population, play an important role in the process of maturation of the claustrum. This is confirmed by the occurrence of these types of neurons at definite stages of maturation and by the increase in their number.
