Abstract
The external globus pallidus (GPe) coordinates action-selection through GABAergic projections throughout the basal ganglia. GPe arkypallidal (arky) neurons project exclusively to the dorsal striatum, which regulates goal-directed and habitual seeking. However, the role of GPe arky neurons in reward-seeking remains unknown. Here, we identified that a majority of arky neurons target the dorsolateral striatum (DLS). Using fiber photometry, we found that arky activities were higher during random interval (RI; habit) compared to random ratio (RR; goal) operant conditioning. Support vector machine analysis demonstrated that arky neuron activities have sufficient information to distinguish between RR and RI behavior. Genetic ablation of this arkyGPe→DLS circuit facilitated a shift from goal-directed to habitual behavior. Conversely, chemogenetic activation globally reduced seeking behaviors, which was blocked by systemic D1R agonism. Our findings reveal a role of this arkyGPe→DLS circuit in constraining habitual seeking in male mice, which is relevant to addictive behaviors and other compulsive disorders.

Abstract
Metabotropic glutamate receptors (mGluRs) have been recently implicated as robust therapeutic targets for Parkinson's disease (PD). Here, we explored how activation of mGluRs in globus pallidus (GP) affected the amphetamine-induced rotational behavior in the unilateral 6-hydroxydopamine (6-OHDA) lesion rat model of PD. The amphetamine-induced rotations were completely suppressed by the ipsilateral intrapallidal injection of the non-selective mGluR agonist, 1-aminocyclopentane-1S,3R-dicarboxylic acid (ACPD) and the selective group I mGluR agonist, (R,S)-3,5-dihydroxyphenylglycine (DHPG), but not the selective group III mGluR agonist, l-2-amino-4-phosphonobutyric acid (l-AP4). The suppressive effects were detected at 2, 4, 6, 8, and 12 h after ACPD injection, but returned to the control level at 24 h. A remarkable c-fos expression was found in the lesioned side of GP, subthalamic nucleus (STN), and substantia nigra pars reticulata (SNr) of rats that received the ACPD or DHPG injection, compared to rats treated with L-AP-4 or phosphate buffer-injection. The results indicate that the blockade of amphetamine-induced rotations might be at least partially mediated by group I mGluR activation. This study advances the use of selective group I mGluRs directed toward the GP for PD treatment.

Abstract
Movement disorders such as tremor and akinesia observed in Parkinson's disease have been attributed to dopamine (DA) depletion in the basal ganglia. The changes in subcortical neuronal discharge patterns that follow DA depletion have been a matter of much discussion. Here, we implanted rats with chronic recording electrodes bilaterally in the striatum (CPu) and external globus pallidus (GPe), and induced both acute and repeated DA blockade by administration of high-dose haloperidol. Recordings were made in baseline states, as well as before and after haloperidol injections, which rendered rats akinetic. The immediate physiological effect of pharmacological DA blockade was the development of prominent oscillatory firing in the 6-8 Hz range in both CPu and GPe. Importantly, this oscillatory pattern was not accompanied by consistent changes in the firing rate of either CPu or GPe neurons. Cross-correlation analysis further indicated that neurons within the CPu and GPe fired synchronously after DA blockade. Furthermore, although phase lags between neuronal discharges in the GPe and CPu were uniformly distributed prior to haloperidol administration, CPu significantly lagged GPe discharges after repeated DA blockade. Our results demonstrate that acute DA blockade is sufficient to produce synchronous oscillatory activity across basal ganglia neuron populations, and that prolonged DA blockade results in phase lag changes in pallidostriatal synchrony.

Abstract
We previously reported that Sprague-Dawley (SD) rats are significantly more sensitive than Long Evans (LE) rats to disruption of prepulse inhibition (PPI) of the startle reflex by the dopamine agonists, apomorphine (APO) and D-amphetamine (AMPH). This susceptibility is inherited through F1 (SD x LE) and N2 backcross (F1 x SD) generations via an orderly pattern (SD>N2>F1>LE). Here we examined systemic APO (0.5 mg/kg) and AMPH (4.5 mg/kg) modulation of neural activity in four regions of the striatum suspected to be involved in the dopaminergic regulation of PPI - dorsolateral (dlCPu) and medial (mCPu) caudate/putamen and core (NACc) and medial shell (NACms) regions of nucleus accumbens - under conditions that mimicked those used to assess PPI. Immunohistochemical quantification of c-Fos protein expression was used as the surrogate measure of neural activity in SD and LE rats and their F1 crosses. Vehicle-treatment showed significant regional differences in Fos expression, particularly between the dlCPu and the other three areas, but no strain-related differences were observed. Three of four brain areas examined (dlCPu, mCPu and NACc) exhibited drug-induced changes in Fos expression--APO decreased and AMPH increased Fos expression in each region. The aggregate effect across these three regions revealed Fos expression to be significantly greater in LE compared to SD rats for both drugs, with F1 rats intermediate. This pattern of inheritance (LE>F1>SD) reveals an inverse relationship between striatal Fos expression and PPI sensitivity for these drugs; and a positive relationship with reported heritable differences in D2-linked G-protein binding in the CPu and NACc, and with locomotor activation/suppression by AMPH and APO.

Abstract
L-3,4-Dihydroxyphenylalanine (L-DOPA) remains a common treatment for Parkinson's disease; however, side effects (i.e., dyskinesia and hallucinations) also remain problematic. We recently reported that the dopamine metabolite 3-methoxytyramine causes stereotypy in rats via dopamine receptors, raising the possibility that 3-methoxytyramine is involved in the adverse side effects of chronic L-DOPA treatment. Thus, the present study examined the sites of 3-methoxytyramine action in the rat brain. After intracerebroventricular administration of 3-methoxytyramine, significantly more neurones expressed c-Fos in mesocortico-limbic dopamine areas including frontal cortex, medial prefrontal cortex, parietal cortex, piriform cortex, the nucleus accumbens shell, and ventral tegmental area. 3-Methoxytyramine injection into the medial prefrontal cortex specifically resulted in behavioural changes characteristic of those elicited by the more general intracerebroventricular injection of 3-methoxytyramine. This suggests that the medial prefrontal cortex mediates the 3-methoxytyramine-induced behavioural changes and that a reduction of its action there may alleviate the adverse effects of chronic L-DOPA treatment.

Abstract
Systemic administration of a dopamine D2 receptor blocker, haloperidol, but not vehicle, significantly increased the number of c-Fos-immunoreactive neurons in the globus pallidus (GP) in rats. Dual immunohistochemistry, a combination of c-Fos immunohistochemistry and retrograde tracing experiments with cholera toxin B (ChB), revealed that a subset of the c-Fos-immunoreactive GP neurons was pallidostriatal feedback neurons. Lesioning of the subthalamic nucleus (STN) by local injection of ibotenic acid inhibited the haloperidol-induced c-Fos expression in the GP neurons, suggesting that the activation of GP neurons is a result of increased excitatory drives from the STN. Therefore, the present findings are evidence of the existence of the subthalamo-pallido-striatal axis as a feedback system in the internal circuits of the basal ganglia.

Abstract
In the present study, we investigated Fos-like immunoreactivity (FLI) evoked by pallidal dopamine (DA) D1 and D2 receptor blockade in the caudate-putamen (CPu), substantia nigra (SN) and entopeduncular nucleus (EP), i.e. major target areas of pallidal efferents. Results demonstrate that infusion of the selective D1 antagonist SCH23390 (1 and 4 microg/0.5 microl) into the globus pallidus (GP) did not induce FLI in the CPu, SN and EP. In contrast, intrapallidal infusion of a low dose of the selective D2 antagonist S(-)-sulpiride (15 microg/0.5 microl) induced FLI restricted to the CPu. A higher dose of intrapallidal S(-)-sulpiride (25 microg/0.5 microl) induced FLI in the CPu as well as in the SN and EP. These findings add further evidence to notion that the GP plays a central role in the basal ganglia circuitry and demonstrate an involvement of extrastriatal DA via D2 receptors.

Abstract
Anatomical, neurochemical and electrophysiological evidence indicates the presence of multiple neuronal subpopulations within the rodent globus pallidus (GP). One subpopulation that has not been well characterized is GP neurons that express preproenkephalin mRNA (PPE+ cells). The present study seeks to further characterize GP subpopulations by determining whether the PPE+ GP neurons express parvalbumin immunoreactivity (PV-IR) and where their axons project by retrogradely labeling pallidal neurons with the tracer FluoroGold (FG). Using combined PV immunocytochemistry (ICC) and PPE mRNA in situ hybridization, we observed that PV-IR and PPE mRNA identify predominantly separate pallidal cell populations. Combined FG ICC and PPE mRNA in situ hybridization also revealed that this neuropeptide mRNA is more often found in FG-labeled pallidostriatal than pallidosubthalamic neurons. Our data support a growing body of evidence that suggests the GP is more heterogeneous than accounted for by current functional models of the basal ganglia.

Abstract
This study examined the induction of c-Fos expression in the substantia nigra pars reticulata (SNr) and entopeduncular nucleus (EP) in the rats with a globus pallidus (GP) lesion, following the administration of haloperidol. After a GP lesion was made unilaterally by stereotaxic administration of ibotenic acid, haloperidol was administered systemically, and the number of cells expressing c-Fos was quantitatively assessed. Haloperidol induced a high level of the expression of c-Fos in neurons of the SNr and EP, and the GP lesion significantly decreased the expression of c-Fos in the ipsilateral SNr and EP. Since it has been suggested that c-Fos expression in the SNr/EP is caused by increased excitatory inputs from the subthalamic nucleus (STN), the present results provide functional evidence indicating that neuronal activities of the basal ganglia output nuclei are not increased by GP ablation, unlike D2 receptor blockade, supporting the recently proposed hypothesis that overactivity of the STN resulting from dopamine depletion is not solely a result of disinhibition from inhibitory GP efferents.
