Title: Dynamic Nature of Memory Representation and the Hippocampal Network

Abstract:

Memories are encoded through long-lasting changes in the network of the brain. These memory traces can interfere with each other and therefore lead to instability of the representations. Indeed, a previous study discovered that instability is preferentially embedded within spatial maps in memory engram cells in the hippocampus even though their activity is still functionally linked to memory-relevant behaviors (Tanaka et al., 2018). Notably, higher instability of place cells is often observed in aberrant network states caused by various factors, including aging, stress, or epileptic seizure, which cause memory impairments (e.g., Yan et al., 2003; Kim et al., 2007; Karnam et al., 2009). These studies highlight two distinct types of instability leading to the opposite outcomes of hippocampal memory. In my talk, I will introduce our unpublished studies aiming at 1) elucidation of neuronal underpinning that survives extreme plasticity yet supports memory and 2) development of a novel approach to reset the aberrant network state. These studies will provide fundamental insight into physiological and pathological instability in the neuronal network.

We hope to see you there.

Colonial scientific practices are embedded in current scientific research, policy, education, and outreach. It is therefore necessary to acknowledge and undo colonial structures and processes and change practices and mindsets within science and scientific communities. A keynote presentation and subsequent panel will address colonial scientific practices, the negative scientific developments that are caused by them, and how to move towards an inclusive science system, globally.

Along with OIST president Peter Gruss and assistant professor Paola Laurino, this session will engage participants and viewers in career questions and answers such as: “At the start of my career, am I better off seeking collaborations, avoiding them in the name of independence, or placing myself somewhere on a continuum between the two?”

What is a “good” company, and how can it create the highest possible value for itself and each of its stakeholders?

Title: Electron Spin Resonance Measurement of a Single Molecule by Combining RF Signal with Scanning Tunneling Microscopy

Abstract:

The application of magnetic molecules to the materials of the devices for the quantum information process attracts attention. It is critical to make the sharp spin state of the molecule coupled efficiently with the electric current and substrate. The double-decker phthalocyanine complex of bis(phthalocyaninato)terbium(III) (TbPc2) molecule showed intriguing single-molecule magnet (SMM) behavior and was examined on the substrates Au(111) and Ag(111). Here, we studied the TbPc ₂ molecule adsorbed on the superconducting substrate of NbSe2 to demonstrate the use of the mix states between the SMM spins and the superconducting state. By combing with the radio frequency microwave injection shown in Figure 1, we can manipulate the qubit system of the SMM molecule.

Experimentally, we show the scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) studies at the sample temperature of 400 mK (Unisoku, Japan) for the system of TbPc ₂ molecules. The system is equipped with 10 T magnet and the microwave injection system.

First, we observed Yu-Shiba-Rusinov (YSR) states formed by the superconductor and the magnetic molecule systems, which appear in the superconducting gap. Figure 2 shows the YSR state induced by the magnetic field of the TbPc ₂ molecule, which can be manipulated with the molecule's structural configuration. Next, we examine the ESR/NMR signals detected by the RF signal injection (Figure 3). This has been achieved by monitoring the YSR signal intensity as the function of the RF frequency. The plot shows the resonance at the frequencies expected for the ESR/NMR resonances of the TbPc ₂ molecule. We anticipate our results can be contributed towards the utilization of SMM as the building blocks of the future spintronics devices as well as fascinating application to the data storage or quantum computing.

Abstract:

Cobia ( Rachycentron canadum ) is the only member of the Rachycentridae family and exhibits considerable sexual dimorphism in growth rate. Sex determination in teleosts has been a long-standing basic biological question. The molecular mechanisms of sex determination/differentiation in cobia species is completely unknown. We reported high-quality, chromosome-level genome sequences of male cobia with a genome assembly size of 586.51 Mb (contig/scaffold N50: 86.0 kb/24.3 Mb) and female cobia, 583.88 Mb (79.9 kb/22.5 Mb).

Title: Inference, control and the cortical circuits

Abstract:

The duality of sensory inference and motor control has recently been recognized as the commonality in computations required for the posterior distributions in Bayesian inference and the value functions in optimal control. Meanwhile, an intriguing question about the brain is why the entire neocortex shares a canonical six-layer architecture, while its posterior and anterior halves are engaged in sensory processing and motor control, respectively. Here we consider the hypothesis that the sensory and motor cortical circuits implement the dual computations for Bayesian inference and optimal control,

Abstract: Molecular approaches have revolutionised our understanding of the systematics and evolution of most branches on the tree of life, including corals. Over the last twenty-five years molecular research has revealed that few of the 18 families and 111 genera recognised by Veron (2000) were monophyletic. New techniques and vision promise a more robust and consistent species level taxonomy, but it will take time and there is always likely to be some uncertainty. It is therefore important to establish when taxonomy matters and when it does not. (...)
