F VGLUT1 immunolabeled synaptic terminals in rat striatum ending on spines (A ). Spines (Sp) were recognizable by their little size, the presence of spine apparatus (SA), and also the absence of mitochondria and microtubules. All VGLUT1 synaptic terminals formed asymmetric synaptic contacts, as recognizable by the thick postsynaptic density (PSD). Inside the case of some synaptic contacts, the PSD was perforated (asterisks in C,D). All pictures are in the similar magnification shown in (B).J Comp Neurol.

Note that VGLUT2 contacts on D1 spines and dendrites are far more common than on D1negative spines and dendrites, along with the major difference seems to be inside the greater abundance of small terminals around the D1 structures.J Comp Neurol.

For each neuron types we applied prior details on the kinds of cortical axospinous inputs (IT and PT) to these two neuron varieties, the size frequency distributions for these two cortical input forms, the size frequency distribution for axospinous terminals on retrogradely labeled striatonigral and striatoGPe neurons, plus the present findings on thalamic input to these striatal neuron sorts to derive estimates from the relative abundance of every input type for the two striatal projection neuronJ Comp Neurol.

Note that 62.7 IT and a 37.three thalamic input yields an incredibly close size frequency distribution match for striatonigral neurons. Inside the case of striatoGPe neurons, 54.two PT, 20 IT and 25.8 thalamic yields a close approximation for the a.
