Example Sentences:
(1) However, dopamine turnover (as determined by measuring the rate of decline of dopamine after alpha-methyl-p-tyrosine treatment) was not significantly different in the two accumbal sectors.
(2) These results suggest that the hippocampo-accumbal pathway may play an important role in the development of the sensitization.
(3) The accumbal cell cluster compartment, on the other hand, appears to be a separate entity, with connectional and neurochemical features that are dissimilar to both patch and matrix of neostriatum.
(4) The present data indicate that the neurotensin immunoreactivity-rich ventromedial district of ventral pallidum receives its accumbal input almost exclusively from the shell district of the nucleus accumbens.
(5) Relative to the core and neostriatum, a significantly greater proportion of the tyrosine hydroxylase immunoreactive innervation of the accumbal shell consisted of thin fiber and small bouton profiles.
(6) The accumbal core, alternatively, projects to the dorsolateral ventral pallidal subterritory that lacks appreciable neurotensin immunoreactivity and in many other respects more resembles the adjoining striatopallidal components of the caudate-putamen.
(7) This impairment was dose-dependent (Experiment 2) and mediated by opioid receptors in the accumbens nucleus, because it was removed by a systemic (Experiment 3a) or by an accumbal (Experiment 3b) infusion of naloxone.
(8) The contralateral of the DH, CN, the accumbent nucleus (AN) and the globus pallidus (GP) were tested for reproducibility of the instrumental movement.
(9) The locomotor response to a higher dose of AMPA (0.5 microgram) was greater than the maximum response to intra-accumbal injection of amphetamine and was significantly inhibited only when both the D1 and D2 antagonists were administered together.
(10) ORG 2766 was effective after intra-accumbal, subcutaneous and oral administration.
(11) The isla magna itself is unusual not only for its large size but for lateral extensions encircling a group of accumbal neurons far caudally.
(12) Our results indicate that the nicotine-induced hyperlocomotion may arise primarily from activation of VTA nicotinic cholinoceptors (nAchRs), whereas activation of the accumbal nAchRs is less significant in regard to this effect.
(13) The hyperactivity induced by injection of the dopamine (DA) agonist apomorphine into the nucleus accumbens of rats was dose dependently inhibited by intra-accumbal pretreatment with cholecystokinin (CCK-8) (ED50, 0.34 ng).
(14) Rats with 6-OHDA lesions in the nucleus accumbens which were treated intra-accumbally with control serum during the first week following the lesion showed a similar level of motor activity 3 weeks after the lesion as sham-lesioned rats treated with control serum.
(15) It is proposed that the neuroanatomical asymmetry is in either accumbal efferents or their postsynaptic connections.
(16) The accumbal shell, its exclusive projection to the ventromedial subterritory in the subcommissural ventral pallidum, and the previously reported, almost exclusive projection of that pallidal subdistrict to the mesencephalic ventral tegmental area are discussed in terms of a number of other neurochemical and hodological features that serve to distinguish them sufficiently to suggest that they represent a uniquely specialized part of the basal ganglia.
(17) These power spectra are used to sort for the AEP when certain power values for the (36-42Hz) and the (11-16Hz) are reached in the prestimulus period of the sensory motor cortex, nucleus accumbers and amygdala.
(18) The effects of bilateral intra-accumbal and intrastriatal injections of CCK-8 sulphate and its analogue, caerulein, on apomorphine-induced jaw movements were studied in ketamine-anaesthetized rats after C1 spinal transection.
(19) In the accumbal ICC, satellite neurons are most conspicuous in granule-cell-poor spaces within the isla magna, where many non-granular neurons are uncharacteristically small and chromophobic.
(20) Functional recovery from motor hypoactivity of rats with 6-OHDA lesions in the nucleus accumbens is accelerated by intra-accumbal or subcutaneous treatment with the ACTH-(4-9) analog ORG 2766.
