Sensory Activity-Dependent and Sensory Activity-Independent Properties of the Developing Rodent Trigeminal Principal Nucleus

Postnatal Rats of Cells in the Trigeminal Principal Sensory Nucleus of Electrophysiological Properties and Synaptic Responses

Electrophysiological properties and synaptic responses of cells in the trigeminal principal sensory nucleus of postnatal rats.

In the rodent brain stem trigeminal complex, select sets of neurons form modular arrays or "barrelettes," that replicate the patterned distribution of whiskers and sinus hairs on the ipsilateral snout. These cells detect the patterned input from the trigeminal axons that innervate the whiskers and sinus hairs. Other brain stem trigeminal cells, interbarrelette neurons, do not form patterns and ...

Activity-Dependent Axonal Plasticity in Sensory Systems

The rodent whisker-to-barrel cortex pathway is a classic model to study the effects of sensory experience and deprivation on neuronal circuit formation, not only during development but also in the adult. Decades of research have produced a vast body of evidence highlighting the fundamental role of neuronal activity (spontaneous and/or sensory-evoked) for circuit formation and function. In this ...

Coexpression of VGLUT1 and VGLUT2 in trigeminothalamic projection neurons in the principal sensory trigeminal nucleus of the rat.

VGLUT1 and VGLUT2 have been reported to show complementary distributions in most brain regions and have been assumed to define distinct functional elements. In the present study, we first investigated the expression of VGLUT1 and VGLUT2 in the trigeminal sensory nuclear complex of the rat by dual-fluorescence in situ hybridization. Although VGLUT1 and/or VGLUT2 mRNA signals were detected in all...
