How synapses can enhance sensibility of a neural network
Synaptic Plasticity and Spike Synchronisation in Neuronal Networks
TLDR
The results about the effects of synaptic plasticity on neuronal networks composed by Hodgkin-Huxley neurons show that the final topology of the evolved network depends crucially on the ratio between the strengths of the inhibitory and excitatory synapses.
Weak connections form an infinite number of patterns in the brain
TLDR
This work provides strong evidence that the brain operates locally in a CAS regime, allowing it to have an unlimited number of dynamical patterns, a state that could explain the enormous memory capacity of the brain and give support to the idea that local clusters of neurons are sufficiently decorrelated to independently process information locally.

Optimal dynamical range of excitable networks at criticality
TLDR
It is proposed that the main functional role of electrical coupling is to provide an enhancement of dynamic range, therefore allowing the coding of information spanning several orders of magnitude, which could provide a microscopic neural basis for psychophysical laws.
Active Dendrites Enhance Neuronal Dynamic Range
TLDR
It is claimed that enhancement of dynamic range is the primary functional role of active dendritic conductances, and it is predicted that neurons with larger dendrite trees should have larger dynamic range and that blocking of active conductances should lead to a decrease in dynamic range.
Dynamic Range of Vertebrate Retina Ganglion Cells: Importance of Active Dendrites and Coupling by Electrical Synapses
TLDR
The results from detailed computational modeling studies suggest that the key properties of the ganglion cells that endow them with a large dynamic range are large and active dendritic trees and electrical coupling via gap junctions.
How to enhance the dynamic range of excitatory-inhibitory excitable networks.
TLDR
An inhibitory factor for each excitatory node is proposed and it is suggested that if nodes with high inhibitory factors are cut out from the I layer, the dynamic range could be further enhanced, although the improvement is relatively small compared to the original dynamic range.
Dendrodendritic Electrical Synapses between Mammalian Retinal Ganglion Cells
TLDR
Results give conclusive evidence for electrical synapses via dendrodendritic gap junctions involving connexin36 in α retinal ganglion cells of the same physiological type in the albino rat retina.
Excitatory-inhibitory network in the visual cortex: psychophysical evidence.
TLDR
Experimental and modeling results indicated that long-range connections play an important role in visual perception, possibly mediating the effects of context and suggesting a nonmonotonic relation of the detection threshold with the number of flankers.
Specification of cerebral cortical areas.
TLDR
The radial unit model provides a framework for understanding cerebral evolution, epigenetic regulation of the parcellation of cytoarchitectonic areas, and insight into the pathogenesis of certain cortical disorders in humans.
Information processing in the primate visual system: an integrated systems perspective.
The primate visual system contains dozens of distinct areas in the cerebral cortex and several major subcortical structures. These subdivisions are extensively interconnected in a distributed
