A research group of Dr. Ikegaya and Dr. Fujisawa published a collaborative paper in Science. This study clarified that sharp wave-ripples that generated in the hippocampus during slow-wave sleep prevents saturation of neuronal circuit excitability by inducing long-term synaptic depression (LTD)-like plasticity in hippocampal synapses. This finding gives some answer to one of the biggest mysteries of the life sciences as to "why the animal sleeps".

A study by Dr. Fujisawa and colleagues has been published in Science. They found that information reflecting the spatial location of both the self and the other was jointly and encoded by CA1 pyramidal cells in the observer rat.
A new paper jointly authored by Takagi, Fujita, et al. entitled “Use of incidentally encoded memory from a single experience in cats”has been published in Behavioural Processes. The study found that cats, like dogs, are able to retrieve and adaptively use “what” and “where”
information from an incidentally encoded memory from a single experience. This imply an episodic memory system in cats.The study was widely covered by the media including BBC News.

The joint symposium of Science of Mental time and Oscillology and 2nd our general meeting in FY2016 was held in Tokyo.
We had the cosponsored work shop on Evo-Devo of Vocal Learning and Plasticity at the University of Tokyo.Vocal learning and plasticity led the emergence of human language. We discussed the process in which vocalizations, a time domain signal, was acquired and shaped via two different time scales: development and evolution.
The 1st general meeting in FY2016 was held in Sapporo, Hokkaido. 81 of member joined and presented their own research.
A new study by Professor Kitazawa and colleagues has appeared in Neuron.
Error signals for adapting to errors in reaching was shown to be submitted well before we get even aware of the error.
