Burst firing in midbrain dopaminergic neurons
Brain Research Reviews, 1997Midbrain dopaminergic (DA) neurons fire bursts of activity in response to sensory stimuli, including those associated with primary reward. They are therefore conditional bursters - the bursts conveying, amongst other things, motivationally relevant information to the forebrain. In the forebrain, bursts give rise to a supra-additive release of dopamine,

ELECTROPHYSIOLOGICAL EFFECTS OF AMPHETAMINE ON DOPAMINERGIC NEURONS
Biochemical Pharmacology, 1973Publisher Summary This chapter elaborates the electrophysiological effects of amphetamine on dopaminergic neurons. Antipsychotic phenothiazines and haloperidol were shown to reverse, and block the depressant effect of d-AMP. In addition, one found that blockade of DA synthesis by the intra-peritoneal administration of 50 mg/kg of the tyrosine ...

Dopaminergic neurons in sympathetic ganglia of the dog
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1982Abstract A study has been made of the catecholamine content of various canine sympathetic ganglia. The data have been related to the anatomical location of ganglion cells supplying the kidney and hindpaw. Retrograde transport of horseradish peroxidase from filaments of the renal nerve labelled cell bodies in the ipsilateral renal and ...

Are Chemoreceptor Neurons Dopaminergic?
1990In 1983, two independent groups reported the occurrence of tyrosine hydroxylase (TH) containing primary afferent neurons in some lumbar dorsal root ganglia as well as in the glossopharyngeal and vagal sensory ganglia of the rat (Price and Mudge, 1983; Katz et al., 1983).

Effects of prolactin on central dopaminergic neurons
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1982The activities of various dopaminergic neurons in the brain have been estimated biochemically by quantifying the rate of synthesis or turnover of dopamine in brain regions containing the terminals of these neurons. In addition, the activity of tuberoinfundibular dopaminergic neurons have been estimated from the concentration of dopamine in pituitary ...

Function of Wnts in Dopaminergic Neuron Development
Neurodegenerative Diseases, 2006Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson’s disease (PD). Proof of principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources.

Genetic control of dopaminergic neuron differentiation
Trends in Neurosciences, 2005The mesencephalic dopaminergic (mesDA) system controls movement and emotional behaviour, and its degeneration causes Parkinson's disease and other psychiatric disorders. Recent findings are leading to better understanding of the genetic control of generation and functioning of the mesDA system.

Molecular Determinants of A9 Dopaminergic Neurons
NeuroMolecular MedicineIn the human brain, the nigrostriatal pathway regulates motor functions, and its selective deterioration leads to the onset of Parkinson's disease (PD), a neurodegenerative disorder characterized by motor dysfunction and significant disability. The A9 neurons, a subgroup of ventral mesencephalic dopaminergic (DA) neurons, form the nigrostriatal pathway
