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

The response of cortical neurons to in vivo-like input current: theory and experiment: II. Time-varying and spatially distributed inputs
TL;DR: This article focuses on the response of integrate-and-fire neurons and real cortical neurons to long-lasting, noisy, in vivo-like stationary inputs and shows how the theory can predict the observed rhythmic activity of cultures of neurons.

Depth-Dependent Temporal Response Properties in Core Auditory Cortex
TL;DR: Neural responses simultaneously across cortical depth in primary auditory cortex and anterior auditory field of CBA/Ca mice are recorded and systematic depth dependencies in responses to second-and-later noise bursts in slow (1–10 bursts/s) trains of noise bursts are found.

A recurrent dynamic model for correspondence-based face recognition.
TL;DR: A fully neural, functionally competitive, and correspondence-based model for invariant face recognition by recurrently integrating information about feature similarities, spatial feature relations, and facial structure stored in memory is created.

High-throughput microcircuit analysis of individual human brains through next-generation multineuron patch-clamp.
Yangfan Peng,Franz Xaver Mittermaier,Henrike Planert,Ulf C. Schneider,Henrik Alle,Jörg R. P. Geiger +5 more
TL;DR: An in vitro multipatch setup with an automated pipette pressure and cleaning system facilitating recordings of up to 10 neurons simultaneously and sequential patching of additional neurons is introduced, which will facilitate the systematic analysis of microcircuits and allow unprecedented assessment of inter-individual variability.

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.
