Prior studies showed that positive alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor modulators facilitate long-term potentiation (LTP) and improve the formation of several types of memory in animals and humans. However, these modulators are highly diverse in their effects on receptor kinetics and synaptic transmission and thus may(More)
BACKGROUND Few attempts have been made to clarify the relational development of the hypothalamo-adenohypophysial and -neurohypophysial systems in species higher than amphibians. METHODS The appearance and topographical distribution of endocrine and neuroendocrine cells and fibers in these systems were immunohistochemically examined in the larvae of(More)
Since thyroid-stimulating hormone (TSH) producing cells are thought to play an essential role during metamorphosis, their development was immunohistochemically examined to reveal the appearance and topographical changes in the distribution in the hypophysis of Xenopus laevis tadpole from hatching to the end of metamorphosis. TSH-immunoreactive cells(More)
Simultaneous stimulation of the antennal lobes (ALs) and the ascending fibers of the ventral nerve cord (AFV), two sensory inputs to the mushroom bodies (MBs), induces long-term enhancement (LTE) of subsequent AL-evoked MB responses. LTE induction requires activation of at least three signaling pathways to the MBs, mediated by nicotinic acetylcholine(More)
Conditioned taste aversion (CTA) induced by the application of a novel taste such as sodium saccharin (Sac) as the conditioned stimulus (CS) and a malaise-inducing agent as the unconditioned stimulus (US), results in acquisition of CTA memory to Sac. In contrast, CTA is extinguished by repeated presentations of the CS without the US, resulting in(More)
