Electron microscopic demonstration of caudal afferents to the rat interpeduncular nucleus
Neuroscience, 1980Abstract Analysis of the synaptology of the rat interpeduncular nucleus is of interest, amongst other reasons, because of morphological and biochemical evidence for synaptic sprouting following lesions of the habenular nucleus. Thus far only the synapses arising from the habenulointerpeduncular afferent axons have been identified by electron ...

Left-right pairing at the crest synapses of rat interpeduncular nucleus
Neuroscience, 1983Synaptic terminals of the habenulo-interpeduncular axons in rat interpeduncular nucleus are demonstrated by electron-microscopic autoradiography following [3H]leucine injection into the habenula. The endings are of two types, S and crest synapses. Previous descriptions of the S synapses based on indirect identification were confirmed.

Connections of the laterodorsal tegmental nucleus with the habenular‐interpeduncular‐raphe system
Journal of Comparative Neurology, 2019AbstractThe laterodorsal tegmental nucleus (LDTg) is a hindbrain cholinergic cell group thought to be involved in mechanisms of arousal and the control of midbrain dopamine cells. Nowadays, there is increasing evidence that LDTg is also engaged in mechanisms of anxiety/fear and promotion of emotional arousal under adverse conditions.

We used correlative biochemical and histochemical methods to examine (1) the norepinephrine (NE) projection from the paired locus coeruleus (LC) to the midline interpeduncular nucleus (IPN) of the adult rat and (2) the ability of the LC to respond to denervation of their target following removal of noradrenergic afferents (6-hydroxydopamine lesions of ...

Effect of neonatal deafferentation on synaptogenesis in the rat interpeduncular nucleus
Journal of Comparative Neurology, 1978AbstractChanges in the normal synaptogenetic pattern of the interpeduncular nucleus (IPN) were induced by destruction of one or both habenular nuclei in neonatal rats. The S synapses, the principal habenulointerpeduncular (H‐IPN) afferents, were reduced in number and delayed in time of appearance by unilateral lesions. They were eliminated by bilateral

Subthalamic Nucleus Targeting Using Interpeduncular Cistern as an Internal Landmark
Operative Neurosurgery, 2011Internal landmarks for the subthalamic nucleus (STN) have been used in past. This study uses a yet-unused internal landmark to refine STN targeting.To determine the effect of the width of the interpeduncular cistern (IPC) on STN targeting during placement of deep brain stimulation (DBS) for Parkinson disease.Fifty consecutive patients with Parkinson ...

A cluster analysis of the neurons of the rat interpeduncular nucleus.
Journal of anatomy, 1995The morphometric characteristics of the neurons of the interpeduncular nucleus (IPN) in the rat were investigated by cluster analysis in order to identify neuronal groups which are morphometrically homogeneous, and to define their position and density in the IPN subnuclei. Two clusters of cells were detected.

The morphology of the interpeduncular nucleus of man: a Golgi observation.
Zeitschrift fur mikroskopisch-anatomische Forschung, 1983The interpeduncular nucleus (ITP) of man has been studied from a human brain impregnated "in toto" by the Golgi method. A wax model reconstructed from serial sections gives information on its size, its shape and its position within the brain. Its volume was also calculated.
