YNiC seminar 3rd December
by rem 30 Nov '09

30 Nov '09

Dear Users This week I will give a talk based on an article that is currently "in press" in NeuroImage. The article is about using magnetoencephalography to investigate the spatiotemporal representation of changes in pitch over time (frequency modulation). YNiC seminars take place from 4-5 pm in YNiC open plan. Everyone is welcome to attend. Best wishes Rebecca Citation: Rebecca E. Millman, Garreth Prendergast, Padriag T. Kitterick, Will P. Woods and Gary G. R. Green. (2010). Spatiotemporal reconstruction of the auditory steady-state response to frequency modulation using magnetoencephalography. NeuroImage 49, 745-758. Abstract: The aim of this study was to investigate the mechanisms involved in the perception of perceptually salient frequency modulation (FM) using auditory steady-state responses (ASSRs) measured with magnetoencephalography (MEG). Previous MEG studies using frequency-modulated amplitude modulation as stimuli (Luo et al., 2006, 2007) suggested that a phase modulation encoding mechanism exists for low (< 5 Hz) FM modulation frequencies but additional amplitude modulation encoding is required for faster FM modulation frequencies. In this study single-cycle sinusoidal FM stimuli were used to generate the ASSR. The stimulus was either an unmodulated 1-kHz sinusoid or a 1-kHz sinusoid that was frequency-modulated with a repetition rate of 4, 8, or 12 Hz. The fast Fourier transform (FFT) of each MEG channel was calculated to obtain the phase and magnitude of the ASSR in sensor-space and multivariate Hotelling's /T/^2 statistics were used to determine the statistical significance of ASSRs. MEG beamformer analyses were used to localise the ASSR sources. Virtual electrode analyses were used to reconstruct the time series at each source. FFTs of the virtual electrode time series were calculated to obtain the amplitude and phase characteristics of each source identified in the beamforming analyses. Multivariate Hotelling's /T/^2 statistics were used to determine the statistical significance of these reconstructed ASSRs. The results suggest that the ability of auditory cortex to phase-lock to FM is dependent on the FM pulse rate and that the ASSR to FM is lateralised to the right hemisphere.

Dear Users, can I flag this up to the young, keen and eager researchers at YNiC. It's a poster competition at the House of Commons, run by the Parliamentary and Scientific Committee. I found it a very useful experience a few years ago. http://www.vmine.net/setforbritain/2010event.asp Michael

Light-emitting sensors of neuronal activity (reporting calcium increase, neurotransmitter release, or membrane depolarization) have begun to reveal how information is represented by neuronal assemblies, and how these representations are transformed during the computations that inform behaviour. Light-driven actuators control the electrical activity of central neurons in freely moving animals and establish causal connections between the activities of specific neurons and the expression of particular behaviours. The combination of finely resolved optical field sensing and finely resolved optical field actuation is opening new dimensions for the analysis of the connectivity, dynamics, and plasticity of neuronal circuits, and perhaps even for replacing lost---or designing novel---functionalities.
