Conditional targeting of medium spiny neurons in the striatal matrix
The striatum serves as the main input to the basal ganglia, and is key for the regulation of motor behaviors, compulsion, addiction, and various cognitive and emotional states. Its deterioration is associated with degenerative disorders such as Huntington's disease. Despite its apparent anatomical uniformity, it consists of intermingled cell populations, which have precluded straightforward ana...
متن کاملDifferential tonic GABA conductances in striatal medium spiny neurons.
Medium spiny neurons (MSNs) provide the principal output for the dorsal striatum. Those that express dopamine D2 receptors (D2+) project to the globus pallidus external and are thought to inhibit movement, whereas those that express dopamine D1 receptors (D1+) project to the substantia nigra pars reticulata and are thought to facilitate movement. Whole-cell and outside-out patch recordings in s...
متن کاملState-Dependent Calcium Signaling in Dendritic Spines of Striatal Medium Spiny Neurons
Striatal medium spiny neurons (MSNs) in vivo undergo large membrane depolarizations known as state transitions. Calcium (Ca) entry into MSNs triggers diverse downstream cellular processes. However, little is known about Ca signals in MSN dendrites and spines and how state transitions influence these signals. Here, we develop a novel approach, combining 2-photon Ca imaging and 2-photon glutamate...
متن کاملDichotomous anatomical properties of adult striatal medium spiny neurons.
Principal medium spiny projection neurons (MSNs) of the striatum have long been thought to be homogeneous in their somatodendritic morphology and physiology. Recent work using transgenic mice, in which the two major classes of MSN are labeled, has challenged this assumption. To explore the basis for this difference, D(1) and D(2) receptor-expressing MSNs (D(1) and D(2) MSNs) in brain slices fro...
متن کاملPeering into the Dendritic Machinery of Striatal Medium Spiny Neurons
Striatal medium spiny neurons are principal players in the basal ganglia macrocircuits implicated in an astonishing array of psychomotor disorders, including Parkinson's disease, schizophrenia, Huntington's disease, and drug abuse. Using an elegant combination of 2-photon laser scanning microscopy and 2-photon uncaging of glutamate, Carter and Sabatini (this issue of Neuron) provide our first g...
