Reconstruction and Simulation of Neocortical Microcircuitry

Anastasia Ailamaki, Henry Markram, Sean Lewis Hill, Eilif Benjamin Muller, Rodrigo de Campos Perin, Lida Kanari, Srikanth Ramaswamy, Vincent Delattre, Michael Reimann, Ying Shi

We present a first-draft digital reconstruction of the microcircuitry of somatosensory cortex of juvenile rat. The reconstruction uses cellular and synaptic organizing principles to algorithmically reconstruct detailed anatomy and physiology from sparse ex ...

Computing the size and number of neuronal clusters in local circuits

Henry Markram, Rodrigo de Campos Perin, Martin Telefont

The organization of connectivity in neuronal networks is fundamental to understanding the activity and function of neural networks and information processing in the brain. Recent studies show that the neocortex is not only organized in columns and layers b ...

A Biophysically Detailed Model of Neocortical Local Field Potentials Predicts the Critical Role of Active Membrane Currents

Henry Markram, Rodrigo de Campos Perin, Sean Lewis Hill, Michael Reimann

Brain activity generates extracellular voltage fluctuations recorded as local field potentials (LFPs). It is known that the relevant microvariables, the ionic currents across membranes, jointly generate the macrovariables, the extracellular voltage, but ne ...

A computer-assisted multi-electrode patch-clamp system

Henry Markram, Rodrigo de Campos Perin

The patch-clamp technique is today the most well-established method for recording electrical activity from individual neurons or their subcellular compartments. Nevertheless, achieving stable recordings, even from individual cells, remains a time-consuming ...

A synaptic organizing principle for cortical neuronal groups

Henry Markram, Rodrigo de Campos Perin, Thomas Berger

Neuronal circuitry is often considered a clean slate that can be dynamically and arbitrarily molded by experience. However, when we investigated synaptic connectivity in groups of pyramidal neurons in the neocortex, we found that both connectivity and syna ...

Organizing neural networks

Henry Markram, Rodrigo de Campos Perin, Thomas Berger

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for organizing trained and untrained neural networks. In one aspect, a neural network device includes a collection of node assemblies interconnected by betwe ...

Ephaptic coupling of cortical neurons

Henry Markram, Rodrigo de Campos Perin, Constantinos Anastassiou

The electrochemical processes that underlie neural function manifest themselves in ceaseless spatiotemporal field fluctuations. However, extracellular fields feed back onto the electric potential across the neuronal membrane via ephaptic coupling, independ ...

Innate neural assemblies for lego memory

Henry Markram, Rodrigo de Campos Perin

Brief Bursts Self-Inhibit and Correlate the Pyramidal Network

Henry Markram, Rodrigo de Campos Perin, Gilad Silberberg, Thomas Berger

Inhibitory pathways are an essential component in the function of the neocortical microcircuitry. Despite the relatively small fraction of inhibitory neurons in the neocortex, these neurons are strongly activated due to their high connectivity rate and the ...

Emergent Dynamics in Neocortical Microcircuits

Rodrigo de Campos Perin

Interactions among neurons can take place in a wide variety of forms. It is the goal of this thesis to investigate the properties and implications of a number of these interactions that we believe are relevant for information processing in the brain. Neuro ...
