YNiC seminar 2nd February
by rem 30 Jan '12

30 Jan '12

Dear Users This Thursday (4.15-5.15 pm) Mark Hymers and Padraig Kitterick will be giving a talk on "Safe levels of noise exposure in MR scanning at YNiC". Please see below for the talk abstract. Everyone is welcome to attend. Best wishes Rebecca Abstract: In 2011 Mark Hymers, Padraig Kitterick, Rebecca Millman and Quentin Summerfield were awarded a small grant by the Department of Psychology to investigate the feasibility of carrying out auditory fMRI research safely at YNiC. This talk will present the main findings of the work funded by this grant and should be 1) of interest to anyone who uses MRI and 2) of particular interest to those who wish to carry out auditory fMRI experiments. MR scanners generate very loud levels (>105 dB SPL) of noise. Exposure to intense noise can potentially damage hearing and the effects of exposure to very loud sounds are cumulative over the total exposure time. Researchers who use MR scanners must protect their participants against hearing damage by ensuring that exposure to noise levels in MR remain within the UK legal limits. Important considerations that will impact the design of all MRI experiments are 1) the duration of the structural scans/fMRI experiments and 2) the amount of attenuation of unwanted noise provided by hearing protection available at YNiC. For auditory fMRI experiments, researchers must also take into account the effects of adding the presentation level of auditory stimuli to the scanner noise. The talk will provide an overview of the guidelines written by Hymers et al. in the full report and present easy-to-use tools for calculating levels of noise exposure in MRI experiments. -- ************************************************************************ Dr. Rebecca E.

Traditionally, neuroscientists have used neuroimaging to localize different functions to different parts of the brain. However, brain functions depend on dynamical networks spanning many different brain regions. Identifying these networks, and especially networks that show causal interactions among their elements, is a major current challenge. This Ph.D. project will address this challenge for functional MRI (fMRI), the most popular neuroimaging method. fMRI measures time-varying changes in metabolic signatures of neural activity. To identify causal networks, we adopt the framework of Granger causality analysis (GCA) which assumes that causes both precede and help predict their effects. GCA applied to fMRI faces several challenges arising because the fMRI signal is an indirect and incompletely understood reflection of underlying neural activity, is sluggish, delayed, and is sampled only once every 2-3 seconds. The project will address these limitations by novel combinations of theory, modelling and experiment. A first objective will be to adapt recent theoretical findings showing invariance of GCA under filtering to the case of fMRI. A second objective will be to characterize the behavior of GCA on fMRI data via detailed computational models connecting neural activity to simulated fMRI responses. These models will be built by connecting existing large-scale spiking neuron simulations with forward models of hemodynamic responses. Third and finally, the resulting methods will be benchmarked on fMRI data obtained specifically for this purpose. > > The successful candidate will benefit from being part of the Sackler Centre for Consciousness Science (www.sussex.ac.uk/sackler), a world-leading research group in computational neuroscience, functional analysis of neuroimaging data, and consciousness research. The student will enjoy collaborative input from the Department of Informatics, the Brighton and Sussex Medical School, and the School of Psychology; will work within a thriving multidisciplinary group integrating many areas of neuroscience, and will have full access to state-of-the-art computational and neuroimaging facilities.

YNiC seminar today
by rem 12 Jan '12

12 Jan '12

Dear Users Today (4.15-5.15 pm in YNiC) there will be a project proposal presentation given by Markus van Ackeren. The title of the talk is "Cortical Dynamics during Pragmatic Inferences about Action". Please see below for the abstract. Everyone is welcome to attend. Best wishes Rebecca Abstract: A plethora of studies have shown that understanding the meaning of words recruits modality-specific areas in the brain, beyond classical language regions. For example, reading words denotingactions (e.g., grasp) also engages areas in the brain that are primarily involved in the control of ourmotor system. However, the level at which this neural motor system (NMS) might become importantduring language comprehension is still debated. In some theories, action information is regarded asconstitutive of word meaning. Specifically, this idea entails that the activation in the NMS is drivendirectly by the word-from of a word. However, others have argued that NMS is activated after wordmeaning has been accessed, which suggests that the NMS is either compositional or epiphenomenalto language understanding.One way to dissociate between different theories is to study utterances in which what is said (literalmeaning), and what is meant (speaker meaning) are not the same. For example, the utterance “it ishot here” does not contain any action information by itself. However, taking into account theintention of the speaker (theory of mind), the utterance might be interpreted as an implied requestfor action (e.g., to open the window). In a previous study we used fMRI to show that both a) neuralmotor and b) theory of mind regions are sensitive to implied requests, suggesting that actioninformation becomes important at a level beyond literal sentence meaning.In the current project, we are interested in the dynamics of motor and theory of mind regions duringlanguage comprehension. Specifically, we will use a modified version of the previous paradigm inwhich the listener will be asked to focus either on the literal meaning (Is this a sensible sentence?),or the speaker meaning of the utterance (Does the person want something from you?). Our goal isto analyse the interaction between a set of posterior regions using dynamic causal modelling (DCM).Specifically, the previous study revealed a set of regions in the posterior part of the brain that areassociated with language perception (MTG), theory of mind (pSTS/TPJ), and motor control (IPL/SMG)respectively. There are different ways in which these regions might interact when a person focuseson the speaker meaning of an utterance. For example, we could find a facilitation of forwardconnections from MTG to both pSTS/TPJ and IPL/SMG. Alternatively, the backward connectionbetween pSTS/TPJ and IPL/SMG might be facilitated. -- ************************************************************************ Dr. Rebecca E.
