The collection of historical instruments at National Taiwan University.

This article presents three of the historical instruments from the National Taiwan University collection. The instruments were built between 1894 and 1902. The instruments are (1) Meumann's Largest Time Sense Apparatus, (2) Wundt's Pendulum Tachistoscope, and (3) Schumann's Wheel Tachistoscope.

Roles of hippocampal N-methyl-D-aspartate receptors and calcium/calmodulin-dependent protein kinase II in amphetamine-produced conditioned place preference in rats.

This study investigates the roles of hippocampal N-methyl-D-aspartate (NMDA) glutamate receptors and CaMKII (calcium/calmodulin-dependent protein kinase II) in amphetamine-produced conditioned place preference (AMPH-CPP) in rats. An earlier report showed that AMPH-CPP resulted in the enhancement of hippocampal CaMKII activity. In this study, AMPH-CPP significantly increased hippocampal GluR1 receptors, though AMPH-CPP was impaired by either blockade of NMDA receptors (AP5) or inhibition of CaMKII (KN-93) during conditioning.
