It has been well documented that striatal neurons encode and process sensory information. It was the aim of the present experiment to determine the extent to which behavioral experience influenced striatal sensory responses. Single units were recorded in the striatum of awake restrained cats as they were adapted to the recording situation. To facilitate recording, cats were rewarded with milk for remaining quiet and motionless. As animals evidenced familiarity with the testing environment, striatal neurons showed heightened sensory receptivity. These results indicate the important influence of behavioral determinants of striatal sensory responses. The nature of the behavioral experience may determine the way in which sensory information is processed in this part of the basal ganglia.

Background: Fine motor challenges are prevalent in autistic populations. However, little is known about their neurobiological underpinnings or how their related neural mechanisms are influenced by sex. The dorsal striatum, comprised of the caudate nucleus and putamen, is associated with motor learning and control and may hold critical information.

Metabotropic glutamate (mGlu) receptors are candidate drug targets for therapeutic intervention in Parkinson's disease (PD). Here we focused on mGlu3, a receptor subtype involved in synaptic regulation and neuroinflammation. mGlu3 mice showed an enhanced nigro-striatal damage and microglial activation in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

Striatum, the input stage of the basal ganglia, is important for sensory-motor integration, initiation and selection of behavior, as well as reward learning. Striatum receives glutamatergic inputs from mainly cortex and thalamus. In rodents, the striatal projection neurons (SPNs), giving rise to the direct and the indirect pathway (dSPNs and iSPNs, respectively), account for 95% of the neurons, and the remaining 5% are GABAergic and cholinergic interneurons.

The posterior "tail" region of the striatum receives dense innervation from sensory brain regions and is important for behaviors that require sensorimotor integration. The output neurons of the striatum, D1 and D2 striatal projection neurons (SPNs), which make up the direct and indirect pathways, are thought to play distinct functional roles, although it remains unclear if these neurons show cell-type-specific differences in their response to sensory stimuli. Here, we examine the strength of synaptic inputs onto D1 and D2 SPNs following the stimulation of upstream auditory pathways.

In the dorsal striatum (DS), the direct- and indirect-pathway striatal projection neurons (dSPNs and iSPNs) play crucial opposing roles in controlling actions. However, it remains unclear whether and how dSPNs and iSPNs provide distinct and specific contributions to decision-making, a process transforming sensory inputs to actions. Here, we perform causal interrogations on the roles of dSPNs and iSPNs in the posterior DS (pDS) in auditory-guided decision-making.
