Glycinergic "inhibition" mediates selective excitatory responses to combinations of sounds.

In the mustached bat's inferior colliculus (IC), combination-sensitive neurons display time-sensitive facilitatory interactions between inputs tuned to distinct spectral elements in sonar or social vocalizations. Here we compare roles of ionotropic…

Contribution of NMDA and AMPA receptors to temporal patterning of auditory responses in the inferior colliculus.

Although NMDA receptors (NMDARs) are associated with synaptic plasticity, they form an essential part of responses to sensory stimuli. We compared contributions of glutamatergic NMDARs and AMPA receptors (AMPARs) to auditory responses in the inferior…

Activation of synaptic group II metabotropic glutamate receptors induces long-term depression at GABAergic synapses in CNS neurons.

Metabotropic glutamate receptor (mGluR)-dependent homosynaptic long-term depression (LTD) has been studied extensively at glutamatergic synapses in the CNS. However, much less is known about heterosynaptic long-term plasticity induced by mGluRs at…

Electrical stimuli patterned after the theta-rhythm induce multiple forms of LTP.

The induction of long-term potentiation (LTP) by high-frequency stimulation is considered an acceptable model for the study of learning and memory. In area CA1 calcium influx through N-methyl-D-aspartate receptors (NMDARs; nmdaLTP) and/or

Endogenous mGluR activity suppresses GABAergic transmission in avian cochlear nucleus magnocellularis neurons.

GABAergic transmission in the avian cochlear nucleus magnocellularis (NM) of the chick is subject to modulation by gamma-aminobutyric acid type B (GABA(B)) autoreceptors. Here, I investigated modulation of GABAergic transmission in NM by metabotropic…

L-type calcium channels refine the neural population code of sound level.

The coding of sound level by ensembles of neurons improves the accuracy with which listeners identify how loud a sound is. In the auditory system, the rate at which neurons fire in response to changes in sound level is shaped by local networks.…

Acute nicotine and phencyclidine increase locomotor activity of the guinea pig with attenuated potencies relative to their effects on rat or mouse.

Behavioral assays of the responses to psychomotor stimulants can be used to model certain aspects of CNS pathologies such as psychosis and addiction. However, species-dependent differences in the effects of neuromodulators in these assays can…

Localization and function of NK(3) subtype tachykinin receptors of layer V pyramidal neurons of the guinea-pig medial prefrontal cortex.

The NK(3) subtype of tachykinin receptor has been implicated as a modulator of synaptic transmission in several brain regions, including the cerebral cortex. The localization and expression of NK(3) receptors within the brain vary from species to…

mGluRs modulate neuronal firing in the auditory midbrain.

The mechanisms underlying sound-evoked suppression of neuronal firing in the auditory system are poorly understood. To explore these mechanisms in the inferior colliculus (IC), agonists and antagonists targeting different groups of metabotropic…

Glutamate and metabotropic glutamate receptors associated with innervation of the uterine cervix during pregnancy: receptor antagonism inhibits c-Fos expression in rat lumbosacral spinal cord at parturition.

Dorsal root ganglia (DRG) neurons connect the spinal cord and uterine cervix, and are activated at parturition with subsequent stimulation of secondary neurons in the spinal dorsal horn and autonomic areas. Neuropeptide neurotransmitters and…
