Broadband neural encoding in the cricket cercal sensory system enhanced by stochastic resonance
Article Abstract:
The peripheral layers of neural processing in a simple sensory system exhibits broadband stochastic resonance, which is involved in a wide range of biologically relevant stimulus parameters. Stochastic resonance is a phenomenon where increasing the input noise level can improve the output signal-to-noise ratio over a limited range of signal and noise strengths. With the use of information theory, the functional significance of the phenomenon is measured within the context of signal processing.

Brain waves deciphered
Article Abstract:
Information pertaining to sensory stimuli is encoded by sequences of electrical oscillatory activity, commonly referred to as brain waves, coordinated across groups of nerve cells. Various odors are encoded by subsets of the neurons participating in the electrical activity elicited by odor in the olfactory system. Each odor is encoded in a spatio-temporal combinatorial coding scheme wherein different sequences of spatial patterns of around 100 projection neurons are activated.

Stable propagation of synchronous spiking in cortical neural networks
Article Abstract:
Precisely synchronized action potentials are shown to propagate within a model of cortical network activity, recapitulating many features of biological systems. An attractor, giving a stable spiking precision in the (sub)millisecond range, controls the dynamics of synchronization, indicating that a combinatorial neural code is possible within a cortical-like network.
