# NEURON tutorial for implementing simulations of thalmamic relay neurons ``` Alain Destexhe Laboratory for Computational Neuroscience Unité de Neurosciences Intégratives et Computationnelles (UNIC) Centre National de la Recherche Scientifique (CNRS) 91198 Gif-sur-Yvette, France ``` Formerly from (when this work was created): ``` Department of Physiology, Laval University, Quebec G1K 7P4, Canada Destexhe@iaf.cnrs-gif.fr http://cns.iaf.cnrs-gif.fr/Main.html ``` This package is running with the NEURON simulation program written by Michael Hines and available on internet at: - [https://neuron.yale.edu](https://neuron.yale.edu) - [https://nrn.readthedocs.io](https://nrn.readthedocs.io) The package contains mechanisms (`.mod` files) and programs (`.oc` files) needed to simulate different models of thalamocortical (TC) relay neurons, relative to the paper: Destexhe A, Neubig M, Ulrich D and Huguenard JR. Dendritic low-threshold calcium currents in thalamic relay cells. *Journal of Neuroscience* 18: 3574-3588, 1998. [https://pubmed.ncbi.nlm.nih.gov/9570789/](https://pubmed.ncbi.nlm.nih.gov/9570789/) ## Programs - `tc1_cc.oc` - current clamp in 1-compartment TC cell - `tc3_cc.oc` - current clamp in 3-compartment TC cell - `tc200_cc.oc` - current clamp in 200-compartment TC cell (intact cell) - `tc200_vc.oc` - voltage clamp in 200-compartment TC cell (intact cell) - `tcD_cc.oc` - current clamp in 8-compartment TC cell (dissociated cell) - `tcD_vc.oc` - voltage clamp in 8-compartment TC cell (dissociated cell) ## Mechanisms - `hh2.mod` - fast sodium spikes (Na and K currents) - `ITGHK.mod` - T-type calcium current of TC cells - `cadecay.mod` - intracellular calcium dynamics - `VClamp.mod` - mechanism for single-electrode voltage-clamp ## How to run Use autolaunch on modeldb or: ### unix platform: To compile the demo, NEURON and INTERVIEWS must be installed and working on the machine you are using. Just type `nrnivmodl` to compile the mechanisms given in the mod files. Then, execute the main demo program by typing: ``` nrngui mosinit.hoc ``` ### mswin platform: Compile the mechanism (mod) files by using `mknrndll`. Then start the simulation by clicking on `mosinit.hoc` in windows explorer. ### back to any platform: Once the menu and graphics interface has appeared, click on a simulation from the Simulations of TC cells window. Then click on "Init and Run" button to start the simulation on the RunControl window. If you do not see a RunControl window you can bring it to the front by selecting it under Tools from the NEURON main menu.
