Serotonergic and dopaminergic systems as targets for exogenous neurotoxins causing a parkinsonian syndrome
… MPP⁺ had a higher inhibitory potency in the dopaminergic system, while MPTP had a higher inhibitory potency in the serotonergic system. Haloperidol metabolites (HPP⁺, R-HPP⁺, and HPTP) also inhibited both amine transport systems with a greater affinity for the serotonergic system. Additional …

Interactions of Early-life Temperature Exposure, Offspring Genotype and Maternal Care on Later-life Maternal Care Provisioning in Female Rats
… with alterations in the oxytocinergic and dopaminergic systems in the maternal brain and, in turn, maternal care received by pups can alter oxytocinergic and dopaminergic systems in the rat pup brain. Though there has been progress in elucidating the biological mechanisms underlying the …

Alterations of central dopamine receptor sensitivity in the spontaneously hypertensive rat
… have been unrelated to their cardiovascular systems. A few of these studies have indicated possible abnormalities in the dopaminergic systems of SHR. Therefore the present study was undertaken to examine more closely the sensitivity of SHR to stimulation of their dopamine (DA) receptors.

Neuropharmacological Properties of the Histaminergic System in the Zebrafish
… effect of acute ethanol on the histaminergic and dopaminergic systems was analysed. The mRNAs of enzymes synthesizing dopamine and histamine were upregulated by a short ethanol exposure in a dose-dependent manner. The morphology of the histaminergic and dopaminergic systems was unaltered by …

The Role of Mu Opioid Receptors in the Behavioral Effects of Cocaine
… attributed to the ability of cocaine to enhance dopaminergic activity. In addition to its direct effects on monoamine neurotransmitters, cocaine impacts other neurotransmitter systems including the endogenous opioid system. The effects of selectively antagonizing mu opioid receptors on …

The effects of cholinergic and dopaminergic neurons on hippocampal learning and memory processes
Dysfunction of cholinergic and dopaminergic systems has been implicated in memory function de cits that are core pathology and associated features of several neurological disorders. However, in order to develop more effective treatments, it is crucial to better understand how different aspects of …

Neural and neurochemical mechanisms of sustained visual attention
… especially in terms of the role of the midbrain dopaminergic systems using behavioural, pharmacological, neuroimaging and neurochemical methods. A visual discrimination task was developed for measuring sustained attention. To this end, brief visual signals over signal omission had to be detected …

NOVEL DOPAMINERGIC SIGNALING MODULATING HIPPOCAMPAL SYNAPTIC TRANSMISSION
Dopaminergic systems regulate many brain functions and dysfunction of dopaminergic neurotransmission is thought to underlie numerous disorders, including schizophrenia, attention deficit hyperactivity disorder (ADHD), depression and Alzheimer’s disease. In the hippocampus, a dopaminergic projection …

Aspects of tic like behaviour and serotonergic control
… tics are modulated by serotonergic and dopaminergic systems and abnormalities of these systems have been reported in Tourette's Syndrome (TS). Therefore, serotonergic and dopaminergic modulation of tics induced by a thyrotrophin-releasing hormone (TRH) analogue were studied as possible …

Neurological - Molecular Interface in Food Intake and Metabolism in Birds and Mammals
… revealed that genes involved in serotonergic and dopaminergic systems may also play an important role in both appetite regulation and insulin-regulated energy homeostasis in the body weight chicken lines. Intracerebroventricular injection of serotonin in broiler chicks was associated with a dose …
