Kindling of the Interpeduncular Nucleus in Rats
Kindling of the Interpeduncular Nucleus in Ratsopenaire
Brain Research, 1990 The interpeduncular nucleus (IPN) was stimulated electrically while single-cell activity was recorded in the nucleus raphe magnus (NRM) of rats under pentobarbital anesthesia. Two classes of NRM cell were examined, those inhibited (off-cells) and those excited (on-cells) by noxious mechanical skin stimulation. Off-cells (92%) were found to be inhibited

The development of somatostatin immunoreactivity in the interpeduncular nucleus of the cat
Developmental Brain Research, 1985Somatostatin (SS) immunoreactivity was localized in a population of neurons in the interpeduncular nucleus (IPN) of the developing and adult cat. SS-immunoreactive perikarya and fibers were found in several subdivisions of the IPN, but were most heavily concentrated in the central nucleus (IPC). Some immunoreactive fibers appeared to be associated with

Social behavior modulates songbird interpeduncular nucleus function
NeuroReport, 2005 Male zebra finches produce the same song while alone and during courtship of a female. However, singing-related activity in the anterior forebrain nuclei lateral magnocellular anterior nidopallium and Area X markedly depends on the social context. Thus, the anterior forebrain should receive a signal of social context from outside the song system.

Cholinergic systems in the rat brain: II. Projections to the interpeduncular nucleus
Brain Research Bulletin, 1985The cholinergic innervation of the interpeduncular nucleus was investigated by use of fluorescent tracer histology in combination with choline-O-acetyltransferase (ChAT) immunohistochemistry and acetylcholinesterase (AChE) pharmacohistochemistry. Following propidium iodide or Evans Blue infusion into the interpeduncular nucleus, brains were processed ...

Interpeduncular nucleus organization in the rat: Cytoarchitecture and histochemical analysis
Brain Research Bulletin, 1984The organization of the interpeduncular nucleus (IPN) in the adult rat was analyzed using cytoarchitectonic, histochemical and immunohistochemical methods. Four paired and four unpaired subnuclei can be distinguished in the IPN on the basis of neuronal size, morphology, staining characteristics and packing density.

, 1986 Publisher Summary The interpeduncular nucleus (IPN) is a phylogenetically conserved area of the brain. Anatomically, the IPN is unique in that it is primarily an unpaired structure, but receives a significant input from a paired structure, the habenula (Hb).

Cholinergic synapse of the interpeduncular nucleus
Experimental Neurology, 1977Three technically independent approaches have been used to identify cholinergic synapses of the rodent's habenulo-interpeduncular tract. These involved electron-microscopic examination of the interpeduncular nucleus to determine (i) the numbers of degenerating vs normal boutons 2 to 3 days after placement of electrolytic lesions in the habenula; (ii ...
