The medial perforant path (MPP) and lateral perforant path (LPP) inputs to the hippocampal dentate gyrus form two distinct laminar inputs onto the middle and distal aspects of granule cell dendrites. Previous evidence indicated that paired stimuli reliably produced paired-pulse depression (PPD) in the MPP and paired-pulse facilitation (PPF) in the LPP.(More)
When divers are exposed to extreme atmospheric pressures they may exhibit symptoms of the high pressure nervous syndrome (HPNS). Although clinical HPNS symptoms are well described, little is known about the underlying pathophysiologic mechanisms. Special HPNS signs like vertigo and tremor suggested sensory-motor hyperexcitability resulting from brainstem(More)
