Substantia Nigra Hyperactivity in Schizophrenia
Biological Psychiatry, 2013Mapping the clinical features of schizophrenia to circuits in the brain is a major goal for schizophrenia researchers. The prefrontal cortex (PFC), the ventral midbrain, and the striatum are among the brain areas of primary interest. The PFC has been linked to cognitive deficits, especially impairment of working memory.

The role of GABA in the substantia nigra
Nature, 1978STRIATONIGRAL GABAergic fibres are widely believed to exert a tonic inhibitory influence on the dopamine (DA)-containing cells of the substantia nigra (SN), and contraversive and ipsiversive circling behaviour can be explained in terms of a greater or lesser activity of the dopaminergic neurones, respectively1,2. However, the blockade of γ-aminobutyric

Synapses in the rat substantia nigra
Tissue and Cell, 1971The composition and organization of the input to the rat substantia nigra were studied with the electron microscope. Four distinct types of synaptic boutons were described. The first contained small (381 A), clear synaptic vesicles. The second type contained the small, clear vesicles and several large, dense-core vesicles.

Evidence for autapses in the substantia nigra
Brain Research, 1980Intracellular recording and intracellular HRP staining were employed to trace the recurrent terminal plexus of cat substantia nigra pars reticulata neurons. Autaptic neurons were labeled. The axon of an autaptic neuron was found to emit a recurrent collateral which distributed 'en passage' and terminal boutons contacting dendrites of the parent cell ...

The substantia nigra and stereotyped behaviour
European Journal of Pharmacology, 1972Abstract The acute and chronic effects of bilateral lesions of the substantia nigra upon amphetamine- and apomorphine-induced stereotyped behaviour and its modification by haloperidol and arecoline were studied in the rat. A mild spontaneous stereotyped behaviour was observed during the acute stage following the induction of nigral lesions. In order

Culture of Substantia Nigra Neurons
Current Protocols in Neuroscience, 1997AbstractPrimary cultures of nigral tissue are widely used as a model system to assay effects of trophic and toxic agents on dopaminergic neurons. Cultured dopaminergic neurons have been successfully transplanted in animals and led to behavioral improvement in animal models of Parkinson's disease.
