Brain imaging studies in man and single cell recordings in monkey have suggested that medial supplementary motor areas (SMA) and lateral pre-motor areas (PMA) are functionally dissociated concerning their involvement in internally driven and externally cue ...
The role of lactate in brain energy metabolism has recently received renewed attention. Although blood-borne monocarboxylates such as lactate poorly cross the blood-brain barrier in the adult brain, lactate produced within the brain parenchyma may be a sui ...
Local delivery of therapeutic molecules represents one of the limiting factors for the treatment of neurodegenerative disorders. In vivo gene transfer using viral vectors constitutes a powerful strategy to overcome this limitation. The aim of the present s ...
The effects of norepinephrine (NE) on in vitro [3H]glycogenolysis were assessed in slices of cerebral cortex from mice whose cortical noradrenergic innervation had been severely reduced by intracisternal 6-hydroxydopamine (6-OHDA) injections. A supersensit ...
Mouse cerebral cortex slices will synthesize [3H]glycogen in vitro. Vasoactive intestinal polypeptide (VIP) stimulates the enzymatic breakdown of this [3H]glycogen. The concentration giving 50% of maximum effectiveness (EC50) is 26 nM. Under the same exper ...
Normal cellular metabolism produces oxidants which are neutralized within cells by antioxidant enzymes and other antioxidants. An imbalance between oxidants and antioxidants has been postulated to lead to the degeneration of specific populations of neurons ...
Glial cell line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor which has been purified on the basis of its ability to promote the survival of dopaminergic neurons in vitro. GDNF has subsequently been cloned and its sequence shown to be ...
The distribution of vasoactive intestinal peptide binding sites in the rat brain was examined by in vitro autoradiography on slide-mounted sections. A fully characterized monoiodinated form of vasoactive intestinal peptide (M-[125I]VIP) previously shown to ...
