Gamma-band oscillations show striking differences in stimulus selectivity compared to fMRI and broadband field potentials in human visual cortex, and are explained by a novel, image-computable model.
An unexpected species difference in electrical coupling of analogous neuroendocrine dopamine neurons in rats and mice reveals a role for gap junction connectivity as a band-pass filter for oscillation frequency in neural networks.
Neural oscillations are a necessary consequence of efficient coding of sensory signals by a spiking neural network, limited by synaptic delays and noise.
A multi-scale integration of experimental and computational approaches shows how a non-linear dependence of T-type calcium channel gating on GABAB receptor activity regulates thalamic network oscillations.
Hippocampal area CA2 controls low gamma and ripple oscillations, brain waves known to be impaired in schizophrenia, implicating this important brain region in cognition.
Stochastic resonance, triggered by fluctuations in brain state, is found to determine the outcomes of periodic stimulation and how it interacts with brain oscillations.
Computational modelling shows that coupled theta and gamma oscillations in the auditory cortex can decompose speech into its syllabic constituents, and organize the neural spiking at faster timescale into a decodable format.
