By implanting a tiny drug delivery device into the brains of rats, researchers in OIST’s Neural Computation Unit were able to temporarily lower serotonin levels in the part of the brain responsible for patience, and to show that this loss caused the rats to give up before receiving an expected reward.
Ken Maeda, a researcher in OIST’s Marine Genomics Unit, has identified a new freshwater goby species on the islands of Okinawa and Iriomote. The species, Stiphodon alcedo, is described in the latest issue of the journal Cybium.
After a neuron fires an electrical impulse, this impulse needs to be chemically transmitted to another neuron to propagate into the neuronal circuit; otherwise communication would grind to a halt. In a paper published on May 10, 2012 in the journal Neuron, researchers at OIST identify a critical part of that chemical transmission.
The OIST Marine Genomics Unit, in collaboration with Japanese research groups including from the University of Tokyo and Mikimoto Co., Ltd., has completed the first decoding of the genome of the Japanese pearl oyster.
