"Transforming visual information between areas V1 and MT" - Dr Nic Price, Monash University
An OIST neuroscience online seminars (ONOS) talk.
Abstract
The visual system is a complex, hierarchically-organised information processing network. Counter-intuitively, successive areas contain less information about a scene, but neural activity is structured to better represent specific information. For example, neurons in primate area MT convey little colour information, but motion direction can be linearly decoded from their activity. The ongoing activity of individual neurons is highly variable, meaning reliable computation depends on collaborative processing across neural populations. However, it remains unclear how visual information is reliably represented across neurons within an area, and how these representations are transformed between areas to extract specific stimulus properties. To address this, we record visually-evoked activity simultaneously from dozens of neurons in V1 and MT in marmosets.
We use decoding techniques to predict stimulus orientation or direction from activity across a neural population. This has allowed us to show that neural representations are affected by stimulus history: recent motion biases predictions in a manner consistent with perceptual illusions; and luminance and contrast changes affect orientation coding, again in a manner consistent with human sensitivity.
We study inter-area communication by comparing the timing of action potentials in V1 with local field potentials (LFP, a population measure of local dendritic activity) in MT. We have shown that action potentials preferentially occur at specific phases of the LFP, and that motion information is best communicated from V1 to MT at specific phases.
Collectively, this suggests that hierarchical information processing depends on action potentials in privileged subsets of neurons occurring in privileged time windows.

I will review the structure of the fermionic Z2xZ2 orbifolds that produced a large space of phenomenological three generation models. I will discuss the trial and error old school method that gave rise to the first known string derived MSSM models, as well as the more modern classification methods that enables the analysis of large spaces of vacua and extraction of some of the global properties underlying them, e.g. spinor--vector duality. I will discuss a new direction of research that was initiated over the past year. Since the mid-eighties it is known that in addition to the ten dimensional tachyon free heterotic-string vacua there exist tachyonic ten dimensional vacua. In the supersymmetric and non-supersymmetric tachyon free cases the ten dimensional tachyon are projected out by the same projection. I will discuss the construction of phenomenological tachyon free models starting from the tachyonic 10D vacua and their particular features.

Title: How Domain Walls of N=1, D=4 SYM look like
Speaker: Dmitri Sorokin, University of Padua, Italy
Abstract: We review main features of the pure N=1, D=4 SYM with the gauge group SU(N) and its effective description by the Veneziano-Yankielowicz generalized sigma-model. We then indicate that the construction of BPS domain walls interpolating between different SYM vacua requires the presence of a dynamical membrane source. We will show how such a membrane is coupled to the SYM and present the explicit form of BPS domain walls which it creates in the Veneziano-Yankielowicz effective theory. In particular, we will describe 1/2 BPS domain wall configurations with |k| less than or equal to N/3, where k is the membrane charge that sets the "distance" between two distinct SUSY vacua.
