TLDR
It is found that, as has long been suspected by cortical neuroanatomists, the same basic laminar and tangential organization of the excitatory neurons of the neocortex is evident wherever it has been sought.Abstract:
We explore the extent to which neocortical circuits generalize, i.e., to what extent can neocortical neurons and the circuits they form be considered as canonical? We find that, as has long been suspected by cortical neuroanatomists, the same basic laminar and tangential organization of the excitatory neurons of the neocortex is evident wherever it has been sought. Similarly, the inhibitory neurons show characteristic morphology and patterns of connections throughout the neocortex. We offer a simple model of cortical processing that is consistent with the major features of cortical circuits: The superficial layer neurons within local patches of cortex, and within areas, cooperate to explore all possible interpretations of different cortical input and cooperatively select an interpretation consistent with their various cortical and subcortical inputs.read more

Competitive Brain Emotional Learning
TL;DR: The proposed C-BEL is inspired by the competitive property of neucortex’s neurocircuits and indicates the superiority of the approach in terms of its higher ability in non-linear problem solving, function approximation and pattern recognition.

Compositional Few-Shot Recognition with Primitive Discovery and Enhancing.
TL;DR: Zhang et al. as mentioned in this paper proposed an approach to learn a feature representation composed of important primitives, which is jointly trained with two parts, i.e. primitive discovery and primitive enhancing.

Multi-regional module-based signal transmission in mouse visual cortex
John N. Ng,Helén Pál +1 more
TL;DR: In this article , the authors tracked the flow of spiking activity recorded from six interconnected levels of the mouse visual hierarchy and created a cellular-scale directed network graph to uncover two multi-regional communication modules distributed across the hierarchy.

Modulation of Firing Rate by Background Synaptic Noise Statistics in Rat Visual Cortical Neurons
TL;DR: The dependence of neuronal firing rate on the EI delay of the noisy background synaptic conductance suggests that individual excitatory pyramidal neurons are sensitive to the Eitatory to inhibitory balance of the synaptic conductances.

Neuronal functional diversity and collective behaviors.
TL;DR: The scenario, however incomplete and incompletely characterized, is nevertheless promising and warrants further investigation.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.

Distributed Hierarchical Processing in the Primate Cerebral Cortex
TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

Hierarchical models of object recognition in cortex
TL;DR: A new hierarchical model consistent with physiological data from inferotemporal cortex that accounts for this complex visual task and makes testable predictions is described.

Neuromorphic electronic systems
TL;DR: It is shown that for many problems, particularly those in which the input data are ill-conditioned and the computation can be specified in a relative manner, biological solutions are many orders of magnitude more effective than those using digital methods.
