Distinct roles of presynaptic dopamine receptors in the differential modulation of the intrinsic synapses of medium-spiny neurons in the nucleus accumbens

BMC Neuroscience, 2007
Background In both schizophrenia and addiction, pathological changes in dopamine release appear to induce alterations in the circuitry of the nucleus accumbens that affect coordinated thought and motivation. Dopamine acts principally on medium-spiny GABA

Amphetamine Promotes Cortical Up State in Part Via Dopamine Receptors

Frontiers in Pharmacology, 2021
Cortical neurons oscillate between Up and Down states during slow wave sleep and general anesthesia. Recent studies show that Up/Down oscillations also occur during quiet wakefulness.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

A Randomized, Sham‐Controlled Trial of Repetitive Transcranial Magnetic Stimulation Targeting M1 and S2 in Central Poststroke Pain: A Pilot Trial

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Central poststroke pain (CPSP), a neuropathic pain condition, is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) targeted to the primary motor cortex (M1) can alleviate the condition, but not all patients respond. We aimed to assess a promising alternative rTMS target, the secondary somatosensory cortex (S2),

Tetrahydrocannabinol and dopamine D1 receptor

Frontiers in Neuroscience
Dopamine, a neurotransmitter and neuromodulator, is primarily released by dopaminergic neurons in the midbrain, particularly in the substantia nigra and the ventral tegmental area (VTA).

Central interaction of ascorbic acid and D2 dopamine receptors on spatial learning and memory in adult male rats [PDF]

The Iranian Journal of Veterinary Science and Technology, 2014
Previous studies had reported that extracellular levels of ascorbic acid have modulatory effects on dopamine receptors. Both ascorbic acid and dopamine receptor have an important role in learning and memory processes.

Anodal Transcranial Direct Current Stimulation Improves Social Behavior Alongside Neuroplastic Changes in a Tsc2+/− Rat Model of Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by altered synaptic connectivity and network organization, resulting in profound impairments in social communication and interaction. Transcranial direct current stimulation (tDCS) represents a promising approach to modulate maladaptive plasticity associated with ASD;

Dissociable effects of dopamine on neuronal firing rate and synchrony in the dorsal striatum

Frontiers in Integrative Neuroscience, 2009
Previous studies showed that dopamine depletion leads to both changes in firing rate and in neuronal synchrony in the basal ganglia. Since dopamine D1 and D2 receptors are preferentially expressed in striatonigral and striatopallidal medium spiny neurons,

The role of intracerebral dopamine D1 and D2 receptors in sleep‐wake cycles and general anesthesia

Ibrain, 2022
Dopamine (DA), a monoamine neurotransmitter, is synthesized and released mainly by neurons in the ventral tegmental area and the substantia nigra (SN) pars compacta of the midbrain.

Dopamine receptor subtypes and ingestive behaviour [PDF]

, 1999
Both centrally and systemically administered dopamine agonists and antagonists decrease ingestive behaviour. The aim of this thesis was to examine whether drugs acting at different receptor subtypes decreased intake in different ways.
