Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Mechanisms for the modulation of dopamine D1 receptor signaling in striatal neurons
In the striatum, dopamine D1 receptors are preferentially expressed in striatonigral neurons, and increase the neuronal excitability, leading to the increase in GABAergic inhibitory output to substantia nigra pars reticulata.

Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Early adversity and the comorbidity between metabolic disease and psychopathology
Abstract figure legend Hierarchical diagram representing the interplay between the genetic background and early life adversities and its effect on multiple physiological processes that ultimately impact on the risk for the comorbdity between psychopathology and cardiometabolic disorders.

Introduction: The hippocampus (HIP), the primary brain structure related to learning and memory, receives sparse but comprehensive dopamine innervations and contains dopamine D1/D2-like receptors.

Background Interactions between dopamine and glutamate in the prefrontal cortex are essential for cognitive functions such as working memory. Modulation of N-methyl-D-aspartic acid (NMDA) receptor functions by dopamine D1 receptor is believed to play a ...

D1/D5 dopamine receptors modulate spatial memory formation
We investigated the effect of the intra-CA1 administration of the D1/D5 receptor antagonist SCH23390 and the D1/D5 receptor agonist SKF38393 on spatial memory in the water maze. When given immediately, but not 3h after training, SCH23390 hindered long-term spatial memory formation without affecting non-spatial memory or the normal functionality of the ...

Mitochondrial control of ciliary gene expression and structure in striatal neurons
Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.

GLP‐1 at the Metabolic–Cognitive Interface: Reward, Affect, and Memory
GLP‐1R signaling integrates metabolic state with neural circuits controlling reward, mood, and memory, acting as a metabolic‐cognitive interface. In reward pathways, it suppresses hedonic feeding and drug seeking; in affective circuits, sustained signaling promotes anxiolytic and antidepressant effects; and in the hippocampus, it enhances synaptic ...

ABSTRACT The cortico‐basal ganglia pathways that mediate vocal learning in zebra finches (Taeniopygia guttata) are localized in parallel circuits formed by CORE and SHELL subregions. These circuits traverse a specialized region of the basal ganglia essential for vocal learning (Area X), which includes intermixed striatal and pallidal neurons.
