Synchronization and Oscillatory Dynamics in Heterogeneous, Mutually Inhibited Neurons
TLDR
It is shown numerically that the behavior of mildly heterogeneous networks can be related to thebehavior of single, self-inhibiting cells, which can be studied analytically. Expand
Sniffing controls an adaptive filter of sensory input to the olfactory bulb
TLDR
An unexpected functional role for sniffing is suggested and sensory codes can be transformed by sampling behavior alone is shown, suggesting an adaptive filter for detecting changes in the odor landscape. Expand
Hippocampal “Time Cells”: Time versus Path Integration
TLDR
Hippocampal neuronal networks captured both the organization of time and distance in a situation where these dimensions dominated an ongoing experience. Expand
Ion-Channel Noise Places Limits on the Miniaturization of the Brain’s Wiring
TLDR
It is demonstrated that the essential molecular machinery can, in theory, fit into 0.06 microm diameter axons, however, a comprehensive survey of anatomical data shows a lower limit for AP-conducting axons of 0.08-0.1microm diameter, which constrain the wiring density of brains. Expand
Synchronization of Strongly Coupled Excitatory Neurons: Relating Network Behavior to Biophysics
TLDR
This work applies “spike time response” (STR) methods, in which the effects of synaptic perturbations on the timing of subsequent spikes are used to predict how these neurons may synchronize at theta frequencies, to models of layer II stellate cells of the medial entorhinal cortex. Expand
Synchronization in hybrid neuronal networks of the hippocampal formation.
TLDR
The results imply that excitatory SCs, but not inhibitory O-LM interneurons, are capable of synchronizing in phase via monosynaptic mutual connections of the biologically appropriate polarity. Expand
Channel noise in neurons
TLDR
The probabilistic gating of voltage-dependent ion channels is a source of electrical 'channel noise' in neurons that might be exploited by future cochlear implants in order to improve the temporal representation of sound. Expand
Interactions between Distinct GABAA Circuits in Hippocampus
TLDR
It is concluded that GABA(A,slow) cells inhibit both pyramidal cells and GABA (A,fast) interneurons and postulate that this interaction contributes to nested theta/gamma rhythms in hippocampus. Expand
Epilepsy in Small-World Networks
TLDR
This mathematical description explains how specific changes in the topology or synaptic strength in the model cause transitions from normal to seizing and then to bursting, which appear to be general properties of excitatory networks. Expand
Real-Time Linux Dynamic Clamp: A Fast and Flexible Way to Construct Virtual Ion Channels in Living Cells
TLDR
A system for real-time control of biological and other experiments that combines good performance, immense flexibility, low cost, and reasonable ease of use that excels in particular for applications requiring complex control algorithms that must operate at speeds over 1 kHz. Expand
