Studies on Memory: Distribution of Peptidyl-Puromycin in Subcellular Fractions of Mouse Brain
Flexner, L. B., Gambetti, P., Flexner, J. B., Roberts, R. B.
Previous experience has led us to suggest that sustained blockage of memory in mice upon administration of puromycin is caused by the persistence of peptidyl-puromycin at synapses. The block can be...
