BACKGROUND Neuroplastin cell recognition molecules have been implicated in synaptic plasticity. Polymorphisms in the regulatory region of the human neuroplastin gene (NPTN) are correlated with cortical thickness and intellectual abilities in adolescents and in individuals with schizophrenia. METHODS We characterized behavioral and functional changes in inducible conditional neuroplastin-defic...
Damage to the hippocampus (HPC) using the excitotoxin N-methyl-D-aspartate (NMDA) can cause retrograde amnesia for contextual fear memory. This amnesia is typically attributed to loss of cells in the HPC. However, NMDA is also known to cause intense neuronal discharge (seizure activity) during the hours that follow its injection. These seizures may have detrimental effects on retrieval of memor...
Patient RB (Human amnesia and the medial temporal region: enduring memory impairment following a bilateral lesion limited to field CA1 of the hippocampus, S. Zola-Morgan, L. R. Squire, and D. G. Amaral, 1986, J Neurosci 6:2950-2967) was the first reported case of human amnesia in which detailed neuropsychological analyses and detailed postmortem neuropathological analyses demonstrated that dama...
Forty nine adult male Sprague Dawley rats were selected for rapid learning in a T-maze to study the effects of BR-16A, a herbal preparation on ECS-induced retrograde amnesia. Half the rats received 200 mg/kg BR-16A and the other half received vehicle alone. The rats were trained to run into the enclosed chamber of either the left or the right arm on a T-maze; a food pellet served as a reward in...
