Neocortical models in the Open Source Brain repository

------------------------------------------------------

### Introduction

It is in the scientific community’s interest to have a detailed model of the Thalamo - cortical loop. This will aid us in understanding

the role of cortex in processing information. Although there are a few existing models addressing this question, they are not updated with the

latest findings of the field, the model’s development stops with the publication of the results. Also, often such detailed models are

abandoned due to lack of financial and human resources to maintain such projects. New projects are built up from the scratch - this wastes

precious resources, and is like re-inventing the wheel. This project differs specifically in this respect - by making the project

Open, new findings are encouraged to be added, bugs will be acknowledged and subseqently corrected. As it is the community that develops

the project, the findings are open to all - immediately. The central idea is to arrive at a consensus of existing good models of cells and

network alike and to build upon them. This will happen with benchmarking, version control and testing.

### Cellular models

There are a number of detailed cell models from the neocortex in OSB.

#### Generic cortical pyramidal cell

project:pospischiletal2008 (single compartment, conductance based; Regular Spiking (RS) neurons & Intrinsically Bursting (IB) neurons)

project:acnet2 is a network model of the thalamorecipient layer (IV) of primary auditory cortex (AI), and consists of 2 populations, pyramidal cells and basket cell interneurons.

#### Layer 2/3 Pyramidal cell

project:thalamocortical (Fast Regular Bursting & Regular Spiking)

#### Layer 4 Spiny Stellate cell
