Summary: This study investigates the structural changes in the basal ganglia related to levodopa-induced dyskinesia (LID) in Parkinson's disease (PD). The results demonstrate distinct shape alterations, especially in the globus pallidus interna (GPi), in the LID group compared to the non-LID group. These findings suggest the crucial role of the basal ganglia pathway in the development of LID.

Summary: Parkinson's disease is characterized by the degeneration of dopaminergic neurons in the substantia nigra (SN), leading to motor deficits. This study found alterations in the expression of Nav1.1 sodium channels in the basal ganglia (BG) of a PD animal model, with reduced levels in dopaminergic neurons of the SN and increased levels in parvalbumin-positive neurons of the globus pallidus (GP). Blocking these channels with phenytoin improved motor disabilities and reduced synchronous oscillations in the BG.

Summary: Parkinson's disease is a neurodegenerative disorder characterized by the loss of dopaminergic neurons. Recent studies have shown that modulation of GABA and cannabinoid receptors can improve motor functions in Parkinson's disease patients. Therefore, investigating the changes of cannabinoid receptors in different stages of the disease and utilizing them in treatment could be significant for Parkinson's disease management.

Summary: Abnormal involuntary movements, or dyskinesias, are observed in various neurologic disorders, and may be caused by alterations in neural activity or connectivity. This study shows that dysfunction in the indirect pathway of the striatum contributes to the development of dyskinesia in a mouse model, suggesting that hypoactivity in the indirect pathway may be a key mechanism for involuntary movements in other disorders.

Summary: Parkinson's disease is a progressive neurodegenerative disease characterized by both motor and non-motor symptoms. Research suggests that as the disease progresses, gray matter atrophy in Parkinson's patients spreads from the basal ganglia to other brain regions, potentially playing a key role in motor and non-motor circuits.

Summary: This study found that D2-type dopamine receptors and the striatopallidal pathway play important roles in modulating dyskinesia, and suggest that targeting striatopallidal axon terminals at the GPe may have therapeutic potential in the management of LID.

Summary: Insomnia is a common and debilitating aspect of Parkinson's disease, perceived as a multifactorial entity with origins in disease symptoms, comorbidities, therapeutic strategies, and neural degeneration. Recent evidence has provided insights into the neural underpinnings of insomnia in PD, offering potential neuromodulation-based therapeutic avenues for treatment.

Summary: Two new recurrence plot methods were introduced to study the long-term dynamics and interactions between different brain regions. These methods were applied to compare interactions between patients with Parkinson's disease and healthy controls, revealing disruptions in interactions that may contribute to motor disorders and side effects of dopaminergic drugs.

Summary: This review discusses the role of serotonin 5-HT1A receptors and adenosine A2A receptors in dyskinetic movements induced by chronic levodopa in Parkinson's Disease (PD) patients. Preclinical and clinical studies have shown the interaction between serotonin 5-HT1A receptors and other receptors, such as 5-HT1B receptors and adenosine A2A receptors. The combination of 5-HT1A/1B receptor agonists and A2A receptor antagonists effectively counteracts dyskinetic movements induced by chronic levodopa without impairing motor behavior, suggesting a potential therapeutic approach for PD motor deficits and levodopa-induced dyskinesia.

Summary: Parkinson's disease is a neurodegenerative disease influenced by the cannabinoid system in the basal ganglia. Modulating the endogenous cannabinoid levels can have an anti-movement disorder effect, suggesting the development of drugs targeting the cannabinoid system as a novel strategy for Parkinson's disease treatment.

Summary: L-DOPA-induced dyskinesia in Parkinson's disease is associated with oscillatory neuronal activities in the corticobasal ganglia network. Selective agonists of D1 and D2 receptors induce distinct patterns of corticobasal ganglia oscillations, with significant differences among them.

Summary: This study found that the dyskinetic effects of D1 and D2 receptor agonists in Parkinson's disease are associated with distinct patterns of cortico-basal ganglia oscillations. The D1 agonist induced prominent narrowband gamma oscillations, while the D2 agonist resulted in oscillations in the theta band. The findings suggest the recruitment of partially distinct networks in the dyskinetic effects of these receptor agonists.

Summary: In this study, a predictive closed loop control strategy is employed to suppress Parkinson's disease in real-time. Simulation results demonstrate that the proposed MIMO subspace-based predictive controller can effectively suppress PD symptoms with less power consumption compared to conventional open-loop DBS and a recently proposed single-input single-output closed loop controller.

Summary: The genetic inactivation of D2R impairs spatial memory, associative learning, and classical conditioning of eyelid responses, as well as reduces activity-dependent synaptic plasticity in the hippocampal CA1-CA3 synapse. These findings demonstrate the key role of D2R in regulating hippocampal plasticity changes and affecting the acquisition and consolidation of spatial and associative forms of memory.

Summary: Parkinson's disease is a progressive neurodegenerative disease associated with dopaminergic neuron loss and alpha-synuclein. The disease develops from interactions between multiple factors, with mutations in the GBA1 gene being a major genetic risk factor. Cholesterol plays a role in PD pathology, particularly in relation to disturbed cellular cholesterol metabolism.

Summary: Transgenic neuromodulation tools, such as chemogenetic and optogenetic systems, have revolutionized neuroscience by allowing targeted manipulation of neuronal activity with unprecedented specificity. These tools enable mapping of neuroanatomical projection sites and linking cellular manipulations with brain circuit functions and behavior, expanding knowledge of the nervous system in preclinical models. New strategies for implementing and monitoring transgenic tools, such as positron emission tomography (PET) imaging techniques, are needed to track the location and function of chemogenetic receptors and opsins in vivo for safe and effective use in translational research and potential clinical applications.

Summary: Synaptic zinc is an important neuromodulator that affects synaptic transmission and sensory processing. By using a novel dual recombinase transgenic mouse, researchers have been able to study the mechanisms and functions of synaptic zinc in a more controlled and specific manner. The findings from this study reveal a new neuromodulatory mechanism involving zinc release and NMDA receptor activity in the cortex.
