Complex Acoustical Feature Representation in the Zebra Finch Caudomedial Neostriatum (Ncm)
… behavioral responses. In the caudomedial neostriatum (NCM) of the zebra finches, the stimulus selective and contextual (novel vs. familiar) nature of zenk activation as well as results from electrophysiological studies suggest an involvement of this auditory region in complex auditory …

Emerging Auditory Selectivity in the Caudomedial Neostriatum of the Zebra Finch Songbird
… I have demonstrated that the caudomedial neostriatum (NCM), a telencephalic nucleus in the ascending auditory pathway, exhibits responses that range from unselective to highly selective for species-specific stimuli. Sites demonstrating habituating responses are also found and are arranged …

Funktionelle Rekonstruktion der dopaminergen Neurotransmission durch die Transplantation embryonalen ventralen Mesenzephalons im Tiermodell der Parkinsonschen Erkrankung
… Überlebensrate der in ein dopamindenerviertes Neostriatum implantierten fetalen dopaminergen Zellen um den Faktor 1,4 auf 17 bei der Mikro- gegenüber der Makrotransplantation (Überlebensrate 12 ) nach. Von entscheidendem Vorteil für das Überleben der dopaminergen Neurone erwies sich die …

Response Modulation by Single Units in the Auditory Neostriatum of Songbirds: Characterization of Responses and Their Relationships to Nuclear Gene Regulation in Adult and Juvenile Zebra Finches
… early gene (IEG) expression in the caudomedial neostriatum (NCM) of songbirds that are at least 30 days of age (d30) (Mello, et al., 1992; Jin & Clayton, 1997). However, when songbirds are raised in isolation, playback of birdsong fails to induce these genes. To assess the function of this …

The Nature of the Processes, Representations, and Neural Substrates Which Support and Contribute to Motor Sequence Learning
… results challenge the popular claim that the neostriatum is the critical locus of sequence learning, and are discussed in terms of the possible neural circuitry for motor sequence learning.

Νευροφαρμακολογία και λειτουργική ανατομία των βασικών γαγγλίων του εγκεφάλου: Πειραματική μελέτη σε επίμυες
… years however it has become apparent that the neostriatum is not an homogeneous structure. Thus in order to investigate regional differences within striatum concerning asymmetric locomotor behaviours, rats with unilateral, total, dorsal or ventral ibotenic acid induced striatal lesions were …

… LOCALIZATION OF CCK-CONTAINING NEURONS IN THE NEOSTRIATUM OF BOTH SPECIES CONFIRMS PREVIOUS INDICATIONS FOR THE EXISTENCE OF SUCH NEURONS WHEREAS THE GREAT NUMBER OF CCK- CONTAINING NEURONS IN THE DORSAL AND THE LATERAL AREA OFTHE HEDGEHOG HYPOTHALAMUS, IS A FINDING WHICH HAS NOT BEEN REPORTED …

Radial Glia and the Migration of Young Neurons in the Adult Avian Brain
… of the telencephalon (e.g. hyperstriatum, caudal neostriatum and lobus parolfactorius) than in others (e.g. anterior neostriatum, archistriatum and septum), which had few or no radial glia fibers. Radial glia in mammals normally convert into adult astrocytes, their persistence into adulthood in …

Analysis of Immediate-Early Gene Expression in the Songbird Brain Following Song Presentation
… learning. ZENK induction in the caudo-medial neostriatum (NCM, the area with the most marked response) shows a preference for conspecific song and can be habituated by repetitive presentations of the same song, but does not enter an absolute refractory period after habituation, since another …

The sustained delivery of antisense oligodeoxynucleotides using biodegradable polymer microspheres
… ODNs were stereo-taxically administered to the neostriatum of the rat brain. Free ODN resulted in a punctate cellular distribution after 24 hours. In comparison ODN delivered using polymer microspheres were intensely visible in cells 48 hours post administration, and fluorescence appeared to be …

Control of Sexually Dimorphic Brain Pathway Development in Cultured Zebra Finch Brain Slices
… from nucleus HVC (higher vocal center, in the neostriatum) to nucleus RA (robust nucleus of the archistriatum). Fibers from HVC first enter the male RA about day 30 post-hatch, and extend toward but never enter the female RA except in birds given estrogen implants, in the first 1--3 weeks of …

Dynamic Modulation of an Immediate -Early Gene in the Songbird Forebrain
… regions of the auditory forebrain (caudomedial neostriatum (NCM) and caudomedial hyperstriatum ventrale (CMHV)). Three hours of playback leads to the stimulus-specific habituation of this gene response. Here I show that a brief stimulus (1.5 minutes of song) was sufficient to induce zenk mRNA …

Modulation of Signal Transduction in the Nervous System by Protein Phosphorylation
… spiny neurons, the principal cell type of the neostriatum, contain D1 and D2 dopamine receptors. D2 receptor activation is coupled in dissociated neurons to an outward, voltage-dependent, transient K<sup>+</sup>conductance, probably I<sub>A</sub>, as measured by whole-cell patch clamping. This …
