This study reports a 64-year-old right-handed male who manifested bilateral tactile recognition deficits. They were diagnosed as bilateral tactile agnosia, since the patient showed difficulty in semantic association of objects despite preserved hylognosis and morphognosis. The patient had a bilateral lesion in the subcortical region of the angular gyrus. The case reported by Endo et al. (1992) ...

In a study of the capacity of neural grafts to promote functional recovery in rats with fimbria-fornix lesions, 5 groups of rats were studied behaviourally and with acetylcholinesterase (AChE) histochemistry: (1) sham-operated controls; (2) bilateral fimbria-fornix lesions; (3) bilateral lesions plus bilateral solid embryonic septal grafts to the lesion cavity; (4) bilateral lesions plus bilate...

Introduction: The role of midbrain reticular formation, which includes the nucleus cuneiformis (NCF), as a crucial antinociceptive region in descending pain modulation has long been investigated. In this study, we tried to highlight the role of NCF in morphine-induced antinociception in formalin-induced pain model in rats. Methods: A total of 201 male Wistar rats weighing 260-310 g were used in...

We report a new clinically relevant model of neonatal hypoxic-ischemic injury in a 10-day-old rat pup. Bilateral carotid artery occlusion and 8% hypoxia (1 to 15 mins, BCAO-H) was induced with varying degrees of injury (mild, moderate, severe), which was quantified using magnetic resonance imaging including diffusion-weighted and T2-weighted imaging at 24 h and 21/28 days. We developed a magnet...

the unilateral or bilateral lesion of the substantia nigra pars compacta (snc) by chemical neurotoxins such as 6-hydroxy dopamine (6-ohda) or 1- methyl-4- phenyl -1,2,3,6 – tetirahydro pyridine (mptp) are the most commonly and the main used methods for generating the animal models of parkinson’s disease (pd). but these agents are expensive, dangerous, difficult to use and inaccessible convenien...
