expresses expresses GABAergic neuron striatum neuron sst GABAergic neuron of the striatum 2024-11-27T18:33:46Z Some striatal SST GABAergic neurons can co-release glutamate and generate excitation-inhibition responses in postsynaptic neurons. This interneuron type has the least dense dendritic branches in the striatum. In the dorsomedial striatum these neurons regulate the activity of striatal projection neurons. striatal SST+ IN A interneuron of the striatum expressing gamma-aminobutyric acid and somatostatin. This interneuron has a fusiform soma with a diameter between 9 - 25 µm, it has a long axon up to the length of 1mm. This neuron type displays a low threshold Ca2+ spike (LTS), a high input resistance, and the expression of long-lasting plateau potentials following depolarization from rest. SOM cell somatostatin
