Anatomy and Function of Synaptic Zinc in the Striatum
… is the input center of the basal ganglia: the striatum. Environmental enrichment was used to examine potential changes in morphology of striatal cells of mice with (ZnT3 wildtype) and without (ZnT3 knockout) the zinc transporter (ZnT3) necessary to load zinc into vesicles. No changes were found …

Acetylcholine Regulation of the Hippocampus and Striatum During Learning
… place learning, (b) cholinergic activity in the striatum regulates response learning and (c) cholinergic activity in one structure regulates competitive interactions with the other. To this end, rats were tested in tasks in which acquisition of either place or response information led to the …

Alterations In The Mouse Striatum Following Acute And Repeated Ethanol Exposure
<p>Brain-derived neurotrophic factor (BDNF) is an important neuromodulator that has implicated in regard to several neurological disorders, including alcohol addiction. BDNF is also an important modulator of dopamine (DA), a neurotransmitter that is heavily implicated in addiction with one of the …

Beta oscillations in frontal cortex and striatum represent post-processing of successful behavior
… local field potentials in the frontal cortex and striatum of monkeys as they performed single and sequential arm movement tasks. To facilitate these experiments, we developed novel methods for recording simultaneously from independently moveable electrodes implanted chronically at over 100 sites …

The influence of anesthesia and nicotine on dopamine signaling in the rat dorsal striatum
<p>The striatum is highly innervated by dopamine neurons and is involved in movement control (dorsal striatum) reward learning (ventral striatum). Fast-scan cyclic voltammetry (FSCV) is a technique that uses microelectrodes (diameter ~5 μm, length ~150 μm) to monitor dopamine signaling in the …

Development of and proposed applications for tetrodes in functional mapping of rodent sensorimotor striatum
… a group of investigators for use in dorsolateral striatum. Measures were taken to improve the reliability of reaching the target area in the brain and the stability of the implanted tetrode drive over several weeks of recording. Novel methods were developed to confirm the dorsoventral level of …

Effects of MPTP, MPP(+) and Adreno-Medullin on Dopamine Metabolism in the Rat Corpus Striatum
… fragments were inserted directly into the striatum of the MPTP-lesioned animals. Therefore, it was of interest to examine the effects of MPTP and MPP$\sp+$ and of adrenal extract on dopamine metabolism in the corpus striatum. This thesis presents evidence that (1) both MPTP and MPP$\sp+$ …

Wirkung von Cannabinoiden auf die Neurotransmission im Corpus striatum und in der Substantia nigra pars reticulata
… extrapyramidal-motorischen Systems: im Corpus striatum und in der Substantia nigra pars reticulata (SNR). Beide Kerne enthalten viele CB1-Cannabinoidrezeptoren – das anatomische Substrat einer Cannabinoidwirkung ist also gegeben. Schnitte wurden aus Rattengehirn hergestellt und superfundiert. …

Understanding Social Behaviour - Macaque behaviour in coordination and cooperation games and the encoding of inequity in striatum
… by means of single neuron recordings in the striatum of two macaques. We found that inequity modulated task related activity in about 32% of recorded striatal neurons. In addition to this study on inequity we also recorded some sessions in which one of the animals made choices with varying …

Dynamics of dopamine signaling and network activity in the striatum during learning and motivated pursuit of goals
… activity and dopamine release in networks of the striatum, the principle input nucleus of the basal ganglia as rats learned to pursue rewards in mazes. The electrophysiological recordings revealed training dependent dynamics in striatum local field potentials and coordinated neural firing that may …

Changes in the firing patterns in neurons of the sensorimotor striatum during learning : what changes and why
… and specifically the sensorimotor (dorsolateral) striatum, have been implicated in stimulus-response learning. Here, I analyze the role the striatum plays in learning. We recorded from neurons of the sensorimotor striatum as rats learn, are over-trained, are extinguished, and are re-trained on a …

The medial prefrontal cortex and the dorsomedial striatum are necessary for working memory in rats: role of NMDA receptors
… complex cognition. The human frontal cortex and striatum are involved with working memory; however, the mechanisms through which these structures contribute to working memory are incompletely understood. Given the similarities between cortical and striatal areas in the human and rodent brain, I …

Knockout of the glutamate transporter GLT-1 specifically from neurons drastically alters transcriptome profiles in CA3, CA1, and Striatum
… layer V pyramidal neuron axon terminals within striatum. The specific functions of GLT-1 in axon terminals in regulating glutamate homeostasis and synaptic transmission are unknown; in order to investigate these functions, the Rosenberg lab has generated a conditional GLT- 1 KO mouse line where …
