Does inhibition of calcium-independent phospholipase A2 activity in rat hippocampus impair acquisition of short- and long-term memory?
The present results suggest a functional effect of hippocampal PLA(2) on the neurochemistry of memory acquisition and support the hypothesis that reduced PLA(2) activity may contribute to memory impairment in Alzheimer's disease.
CPT and PASAT reduced HS-evoked masseter muscle pain and altered the autonomic response. The increase in heart rate following CPT and PASAT may be caused by different mechanisms. CPT reduced measures of efferent cardiac vagal (parasympathetic) activity, while the PASAT-induced increase in heart rate, but unchanged HRV, may suggest neurohumoral activation.
