Eliminating the VGlut2-dependent glutamatergic transmission of parvalbumin-expressing neurons leads to deficits in locomotion and vocalization, decreased pain sensitivity, and increased dominance

The calcium-binding protein parvalbumin (PV) is a recognized marker of short-axon GABA-ergic neurons in the cortex and the hippocampus. However in addition, PV is expressed by excitatory, glutamatergic neurons in various areas of the brain and spinal cord. Depending on the location of these neurons, loading of their synaptic vesicles with glutamate is mediated by either of three vesicular...

Efferent connections of the parvalbumin-positive (PV1) nucleus in the lateral hypothalamus of rodents

Celio, Marco R. ; Babalian, Alexandre ; Ha, Quan Hue ; Eichenberger, Simone ; Clément, Laurence ; Marti, Christiane ; Saper, Clifford B.

In: Journal of Comparative Neurology, 2013, vol. 521, no. 14, p. 3133–3153

A solitary cluster of parvalbumin-positive neurons – the PV1 nucleus – has been observed in the lateral hypothalamus of rodents. In the present study, we mapped the efferent connections of the PV1 nucleus using nonspecific antero- and retrograde tracers in rats, and chemoselective, Cre-dependent viral constructs in parvalbumin-Cre mice. In both species, the PV1 nucleus was found to project...

Direct comparison between properties of adaptation of the auditory nerve and the ventral cochlear nucleus in response to repetitive clicks

Meyer, Kaspar ; Rouiller, Eric M. ; Loquet, Gérard

In: Hearing Research, 2007, vol. 228, no. 1-2, p. 144-155

The present study was designed to complete two previous reports [Loquet, G., Rouiller, E.M., 2002. Neural adaptation to pulsatile acoustical stimulation in the cochlear nucleus of the rat. Hear. Res. 171, 72–81; Loquet, G., Meyer, K., Rouiller, E.M., 2003. Effects of intensity of repetitive acoustic stimuli on neural adaptation in the ventral cochlear nucleus of the rat. Exp.
