Sentence examples for medial shell of from inspiring English sources

medial shell of nucleus accumbens, mStr medial striatum, Str striatum, SUVRcer standardised uptake value ratio with cerebellum as reference.

Rats were implanted bilaterally with stainless-steel guide cannulae at various rostrocaudal points in the medial shell of NAc.

Local disruptions of either signals in medial shell of NAc generate intense motivated behaviors corresponding to desire and/or dread, along a rostrocaudal gradient.

Specifically, corticolimbic glutamate circuits appear to control the generation in medial shell of motivation components (incentive salience versus fearful salience), but not the generation of hedonic affective states (pleasure 'liking' versus displeasure 'disliking'disliking

Microinjections of a GABAA agonist (muscimol), or of a glutamate AMPA antagonist (DNQX) in medial shell of rats were assessed for generation of hedonic "liking" or "disliking" by measuring orofacial affective reactions to sucrose-quinine taste.

Local activation of GABAA receptors or localized blockade of glutamate AMPA receptors in the medial shell of NAc each generate intense levels of motivated appetitive or fearful behaviors in an anatomically organized pattern of valence.

To probe this issue, here we contrasted GABAergic versus glutamatergic manipulations of medial shell for generation of 1) hedonic 'liking' shifts, measured in affective reactions to sucrose-quinine tandes, and 2) motivation gradients of appetitive and fearful behaviors as described above.

We chose the sagittal plane primarily to map Fos plumes and functions because sagittal view allows the entire rostrocaudal and dorsoventral extents of medial shell to be viewed on a single atlas map.

The effect of medial shell modulation of either GABAergic and glutamatergic transmission was assessed, for distinct group of animals, either on hedonic 'liking' affective response to sucrose-quinine taste using the taste reactivity test or on generation of appetitive or aversive motivated behavior expressed as spontaneous emission of naturalistic eating versus defensive treading behaviors.

For example, in the rostral 25% of medial shell, microinjections of the GABAA agonist muscimol or the glutamate AMPA-kainate antagonist DNQX each generate high levels of pure appetitive behaviors such as eating or drinking [1], [7], [8], [9], [10].

In the current study we investigated the relative roles of DA activity within core and medial shell subregions of the NAc in the processing of spatial and nonspatial information.
