Electrophysiological Characteristics of Globus Pallidus Neurons
Extracellular recordings in primates have identified two types of neurons in the external segment of the globus pallidus (GPE): high frequency pausers (HFP) and low frequency bursters (LFB). The aim of the current study was to test whether the properties of HFP and LFB neurons recorded extracellularly in the primate GPe are linked to cellular mechanisms underlying the generation of action poten...
متن کاملPhylogenetic conservatism in the presence of a neurotensin-related hexapeptide in neurons of globus pallidus.
The vast majority of the pallidal neurons of the hamster, pigeon, caiman and turtle basal telencephalon were positively labeled by an antiserum against LANT-6, a neurotensin-like hexapeptide. In sharks also, LANT-6-positive neurons were observed in the apparent equivalent of the globus pallidus. These results, which imply the coexistence of a LANT-6-like peptide with gamma-aminobutyric acid (GA...
متن کاملFunctional presynaptic HCN channels in the rat globus pallidus.
Hyperpolarization-activated, cyclic nucleotide-gated cation (HCN) channels are expressed postsynaptically in the rodent globus pallidus (GP), where they play several important roles in controlling GP neuronal activity. To further elucidate the role of HCN channels in the GP, immunocytochemical and electrophysiological approaches were used to test the hypothesis that HCN channels are also expres...
متن کاملActivity of neurons in monkey globus pallidus during oculomotor
29 The basal ganglia are a subcortical assembly of nuclei involved in many aspects of 30 behavior. Three of the nuclei have high firing rates and inhibitory influences: the 31 substantia nigra pars reticulata (SNr), globus pallidus interna (GPi), and globus pallidus 32 externa (GPe). The SNr contains a wide range of visual, cognitive, and motor signals that 33 have been shown to contribute to s...
متن کاملIndependent neuronal oscillators of the rat globus pallidus.
In vivo, neurons of the globus pallidus (GP) and subthalamic nucleus (STN) resonate independently around 70 Hz. However, on the loss of dopamine as in Parkinson's disease, there is a switch to a lower frequency of firing with increased bursting and synchronization of activity. In vitro, type A neurons of the GP, identified by the presence of I(h) and rebound depolarizations, fire at frequencies...
