Synchronization as a Mechanism for Attentional Modulation
When attention is shifted to the receptive field of a neuron, the firing of the neuron may become more synchronized with other similar units, as observed in somatosensory cortex [Steinmetz et al, Nature 404,187 (2000)], or with the local field potential at gamma frequencies, as reported for extrastriate cortex [Fries et al, Science 291, 1560 (2001)]. Using simulations, we investigated how such ...
متن کاملInhibitory synchrony as a mechanism for attentional gain modulation q
Recordings from area V4 of monkeys have revealed that when the focus of attention is on a visual stimulus within the receptive field of a cortical neuron, two distinct changes can occur: The firing rate of the neuron can change and there can be an increase in the coherence between spikes and the local field potential (LFP) in the gamma-frequency range (30–50 Hz). The hypothesis explored here is...

متن کاملSynchronization as a mechanism for attentional gain modulation
Responses of neurons in monkey visual cortex are modulated when attention is directed into the receptive field of the neuron: the gain or sensitivity of the response is increased or the synchronization of the spikes to the local field potential (LFP) is increased. We investigated, using model simulations, whether the synchrony of inhibitory networks could link these observations. We found that,...
متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
