Striatal interneurones: chemical, physiological and morphological characterization
The neostriatum is the largest component of the basal ganglia, and the main recipient of afferents to the basal ganglia from the cerebral cortex and thalamus. Studies of the cellular organization ofExpand

Activity Patterns in a Model for the Subthalamopallidal Network of the Basal Ganglia
Based on recent experimental data, we have developed a conductance-based computational network model of the subthalamic nucleus and the external segment of the globus pallidus in the indirect pathwayExpand

The origins of two-state spontaneous membrane potential fluctuations of neostriatal spiny neurons
In vivo intracellular recordings of spontaneous activity of neostriatal spiny cells revealed two-state behavior, i.e., characteristic shifts of membrane potential between two preferred levels. TheExpand

GABAergic microcircuits in the neostriatum
The vast majority of neostriatal neurons and intrinsic intrastriatal synapses are GABAergic, the latter arising from axon collaterals of spiny projection neurons and from GABAergic interneurons. AnExpand

Comparison of IPSCs Evoked by Spiny and Fast-Spiking Neurons in the Neostriatum
Most neurons in the neostriatum are GABAergic spiny projection neurons with extensive local axon collaterals innervating principally other spiny projection neurons. The other source of GABAergicExpand

Potassium currents responsible for inward and outward rectification in rat neostriatal spiny projection neurons
Many of the nonlinear membrane properties displayed by neostriatal spiny projection neurons are conferred by their voltage-gated potassium (K+) currents, including an inwardly rectifying currentExpand

Intrinsic Membrane Properties Underlying Spontaneous Tonic Firing in Neostriatal Cholinergic Interneurons
Neostriatal cholinergic interneurons produce spontaneous tonic firing in the absence of synaptic input. Perforated patch recording and whole-cell recording combined with calcium imaging were used inExpand

Projection subtypes of rat neostriatal matrix cells revealed by intracellular injection of biocytin
Individual neostriatal-matrix spiny neurons were stained intracellularly with biocytin after intracellular recording in vivo, and their axons were traced into the globus pallidus (GP), entopeduncularExpand

Firing patterns and synaptic potentials of identified giant aspiny interneurons in the rat neostriatum
Intracellular recordings were made in vivo from 9 giant aspiny neurons in the neostriatum of urethane-anesthetized rats. The cells were identified by intracellular staining with HRP or biocytin. TheExpand

Spontaneous firing patterns and axonal projections of single corticostriatal neurons in the rat medial agranular cortex.
1. Spontaneous fluctuations of membrane potential, patterns of spontaneous firing, dendritic branching patterns, and intracortical and striatal axonal arborizations were compared for two types ofExpand
