The cortical input mainly ends as terminals that make asymmetric synaptic speak to with dendritic spines of striatal projection neurons, which make up the vast majority of striatal neurons (Albin et al., 1989; Reiner and Anderson, 1990; Gerfen. 1992). The corticostriatal input arises from two neuron kinds, an intratelencephalically projecting (IT) type found predominantly in layer III and upper layer V, along with a pyramidal tract (PT) sort found primarily in decrease layer V (Wilson, 1987; Cowan and Wilson, 1994; Levesque et al., 1996a,b; Levesque and Parent, 1998; Wright et al., 1999, 2001; Reiner et al., 2003; Parent and Parent, 2006). PT-type corticostriatal neurons preferentially make contact with striatal neurons projecting to the external segment of globus pallidus (GPe), even though IT-type cortical neurons preferentially target striatal neurons projecting for the internal pallidal segment (GPi) or the substantia nigra pars reticulata (SNr) (Lei et al., 2004; Cepeda et al., 2008; Reiner et al., 2010). The striatum also receives a substantial excitatory input from the thalamus, which ends in substantial part around the spines and dendrites of striatal projection neurons (Wilson et al., 1982; Smith et al., 2004). The thalamic projection is topographically organized and arises heavily from intralaminar, mediodorsal, and midline thalamic nuclei (IMMC) (Berendse and Groenewegen, 1990; Groenewegen and Berendse, 1994), but in addition from particular sensory nuclei of the thalamus. The IMMC thalamic regions projecting to striatum receive polysensory cortical and brainstem input in addition to a feedback projection from the internal segment from the globus pallidus (GPi). Despite the fact that the precise role of this input is uncertain, it truly is believed to play a function in attentional mechanisms regarding motor arranging and preparedness (Smith et al., 2004, 2009, 2011; Kato et al., 2011). To further characterize the function of this input, we examined the thalamic input to striatum, using a unique interest in determining the relative abundance of axospinous versus axodendritic contacts by thalamostriatal terminals, in comparison to corticostriatal ter.
