Previous studies on the visual origin of time-to-collision (Tc) information have demonstrated that Tc estimates can be based solely on the processing of target expansion rate (optic variable tau). But in the simulated situations used (film clips), there was little reliable information on speed (owing to reduced peripheral vision) and distance (owing to the(More)
In this study we used an immunocytochemical approach to study nestin expression in the rat hippocampus during trimethyltin-induced neurodegeneration at different time points (5, 10, 15, 21 and 50 days) after intoxication. Nestin is transiently expressed by a subpopulation of astroglial cells strictly associated with pyramidal neurons in those hippocampal(More)
The occurrence of neurogenesis in the hippocampus of the adult rat during trimethyltin (TMT)-induced neurodegeneration was investigated using bromodeoxyuridine (BrdU). Fifteen days after TMT intoxication, BrdU-labeled cells were significantly more numerous in the hippocampus of treated animals, gradually decreasing towards the control value 21 days after(More)
S100B is a calcium-binding protein that, in the nervous system, is mainly concentrated in glial cells. Although its biological role is still unclear, the protein is hypothesized, at high concentrations, to act in the pathogenesis of neurodegenerative processes, possibly through oxidative stress mechanisms. To investigate this hypothesis we studied the(More)
