Distal equivalent dendrite
pallidostriatal input Dopaminergic Receptor
D5 and D2 dopamine receptors induce "depolarization and an increase in input resistance in striatal FSI in brain slices" (Tepper JM et al, 20101 ).
striatal input Nicotinic
While nicotinic and muscarinic acetylcholine receptors exist in FSI-SPN synapses, only the nicotinic receptors are postsynaptic. (Tepper JM et al, 20101 ).
pallidostriatal input Gaba
FSIs “have GABAergic inputs originating from the GP. The pallidostriatal inputs are largely selective for FSIs (Bevan et al., 1998) and in vivo, increased firing of FSI during choice selection in a simple discrimination task coincide with a decrease in firing of GP neurons .” (Tepper JM et al, 20101 ).

I K,Ca
The oscillations and the intermittent firing pattern are Ca2+ or SK channel independent, but are completely eliminated by TTX, suggesting that they are due to an interaction between voltage-gated K+ conductances and a persistent or possibly the inactivating sodium conductance responsible for spike generation.” (Bracci E et al, 20032 ). Reviewed in (Tepper JM et al, 20101 ).
I K
In the dorsolateral striatum, only parvalbumin mRNA-positive neurons expressed the mRNA encoding the potassium channel Kv3.1, a member of the Shaw family of potassium channels with rapid activation and inactivation kinetics, usually found in fast-firing neurons such as the basket cells of the hippocampus.” (Lenz S et al, 19943 ).

Gaba striatal connections to SPNs
Striatal FSIs make [GABAergic] synapses onto both direct and indirect path- way SPN. The biophysical properties of the synaptic contacts do not differ and exhibit short-term depression. Further, single FSI often make synapses with both types of SPN” (Tepper JM et al, 20101 ).
