Dopamine and reward : effects of dopamine antagonist drugs on operant and consummatory behaviours
… were observed following administration of sulpiride to the anterodorsal striatum, but not following administration of sulpiride to the nucleus accumbens. The implications of this finding are discussed in relation to the internal organisation of behaviour, and Parkinson's disease. …

Study of the Role of the Bed Nucleus of the Stria Termialis D1- and D2-Like Dopamine Receptors in Cocaine Self-Administering Rats
… dose) , the D2-dopamine receptor antagonist Sulpiride (3.2 microgram total bilateral dose), and D2- dopamine receptor agonist Quinpirole (3.0 microgram total bilateral dose), administered into the BST immediately prior to self-administration sessions, were examined in both sucrose (180-minute …

The role of ventrolateral prefrontal cortex in performance of spatial self-ordered response sequences in the marmoset
… of dopamine receptor D2 antagonist, sulpiride, and 5HT2A receptor antagonist, M100907 on performance of variable sequences. These drugs produced contrasting, dose-dependent impairments. M100907 impaired accuracy, while sulpiride impaired error correction. Chapter 5 studied effects of …

Studies into Amphetamine-Induced Unconditioned Behaviour in the Rat.
… the atypical antipsychotics (clozapine and sulpiride) and a putative antipsychotic (a 5-HT3 antagonist, ondansetron) on open-field locomotor routes taken by rats following treatment with 3.5mg/kg amphetamine. Measures of stereotyped locomotion derived from image analysis were supported by a …

Understanding the role of dopamine in pathology and cognition in Huntington’s disease
… was characterised after administration of sulpiride (a D2 receptor-antagonist). Whilst sulpiride resulted in impaired executive function, there were improvements in other areas of dopamine-dependent cognition, such as reward-based decision-making and facial expression recognition. Taken …

Towards a mechanistic understanding of the neurobiological mechanisms underlying psychosis
… a pharmacological challenge of Bromocriptine or Sulpiride altered glutamate levels in the anterior cingulate cortex. However, no significant group differences were found, between medication groups. In the second results chapter I aimed to address a long-standing question in the field of …

Effect of dopamine on synchronous neuronal oscillations in the globus pallidus-subthalamic nucleus network
… (2 μM) but not by the D2-like antagonists sulpiride (10 μM) and eticlopride (10 μM). Using whole-recordings, dopamine was shown to induce membrane depolarisation. This depolarisation was caused either by a D1-like receptor mediated increase in a conductance which reversed at -34 mV, …

Aspects of tic like behaviour and serotonergic control
… and dopamine D2 antagonists raclopride and sulpiride had no effect on MK771 induced blinking. The D1 antagonists attenuated fore-paw-tremor and -licking while the D2 antagonists were generally without effect on these behaviours. Ketanserin (5-HT2A/ alpha-1 antagonist) and ritanserin …

Reciprocal interactions between feeding and turning motor networks mediate foraging decisions in a predatory sea-slug
… densities reported in other gastropods. Sulpiride, a dopamine antagonist, significantly reduced the animal’s performance in a food-seeking task and attenuated responses to stimuli in the major afferent nerves innervating the cephalic sensory organs. These observations suggest that …
