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 In my talk, I will introduce our unpublished studies aiming at 1) elucidation of neuronal underpinning that survives extreme plasticity yet supports memory and 2) development of a novel approach to reset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.

Neural mechanisms for memory and emotional processing during sleep

The hippocampus and the amygdala are two structures required for emotional memory. While the hippocampus encodes the contextual part of the memory, the amygdala processes its emotional valence. During Non-REM sleep, the hippocampus displays high frequency oscillations called “ripples”. Our early work shows that the suppression of ripples during sleep impairs performance on a spatial task, underlying their crucial role in memory consolidation. We more recently showed that the joint amygdala-hippocampus activity linked to aversive learning is reinstated during the following Non-REM sleep epochs, specifically during ripples. This mechanism potentially sustains the consolidation of aversive associative memories during Non REM sleep. On the other hand, REM sleep is associated with regular 8 Hz theta oscillations, and is believed to play a role in the regulation of emotional reactions and the consolidation of emotional memories (emotional processing). Unraveling the fine neuronal dynamics related to REM sleep, Non-REM sleep and the transitions between states in the hippocampus-amygdala network will further our understanding of the implication of these sleep stages and related brain patterns in emotional processing.

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).

Abstract: As the farming of aquaculture species matures the industry is progressively adopting innovation to increase productivity and lower risk due to disease and environmental perturbations. Technologies based on artificial intelligence and machine learning, rapid diagnostics, biosensors, and integration of genomic data are being developed in efforts to obtain precise information on the health and well-being of the cultured species, along with allowing finer-scale management of the production system.

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,

Hosted by: Professor Timothy Ravasi, OIST Marine Climate Change Unit

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. (...)

Hosted by: Professor Timothy Ravasi, OIST Marine Climate Change Unit

Abstract: The uptake of anthropogenic carbon dioxide (CO2) by the ocean is causing seawater CO2 levels to rise, changing ocean chemistry in a process known as ocean acidification (OA). OA can affect a variety of physiological processes, life history traits and behaviours of fish and marine invertebrates. As invertebrates comprise the vast majority of marine diversity, are essential for key ecosystem processes and support human livelihoods, OA-induced effects of marine invertebrates could have ecological, social and economic consequences.(...)

Title: Are black holes and particles the same thing?

Abstract: I'll discuss the similarities between fundamental particles, thermal systems and black holes. We will play some quantitative games to see exactly how black holes are different from particles in the real world.

Having paid the real world our respects, we will talk about how black holes and fundamental particles *are* the same in string theory - a story rarely covered in popular propaganda, but central to the second superstring revolution. Funny enough, it allows for the "discovery" of new particles through writing down new black hole solutions.

I will then advertise my current work, in which I'm doing exactly that for string theory's wonky cousin, Higher-Spin Gravity.

Part I Title : Discrete geometric analysis and its application Abstract: Discrete geometric analysis is an attempt to discretize geometric analysis. Mathematics is often said “a common language of science”. As our world consists of atoms, which we consider as discrete objects, developing language to describe discrete objects, their geometric structures in particular, is important. I would like to discuss our challenge to establish discrete geometric analysis and its application to other science.
