However, the financial costs associated with the state-of-the-art technology used to manufacture probes and multi-channel recording systems make these experiments virtually inaccessible to small laboratories, especially if located in developing countries. Here, we describe a new method for implanting several tungsten electrode arrays, widely distributed over the brain. Moreover, we designed a headstage system, using the Intan® RHD2000 chipset, associated with a connector (replacing the expensive commercial Omnetics connector), that allows the usage of disposable and inexpensive cranial implants. Our results showed high-quality multichannel recording in freely moving animals (detecting local field, evoked responses and unit activities) and robust mechanical connections ensuring long-term continuous recordings. Our project represents an open source and inexpensive alternative to develop customized extracellular records from multiple brain regions.engUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA ELETRÔNICAENGENHARIA - ESCOLA DE ENGENHARIAICB - DEPARTAMENTO DE FISIOLOGIA E BIOFÍSICAFrontiers in NeuroscienceLaboratóriosEletrodosTungstenioExtracellular electrophysiology recordingLaboratory equipmentIntan TechnologiesElectrode arraysTungsten wiresA Fully Adapted Headstage With Custom Electrode Arrays Designed for Electrophysiological Experimentsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.frontiersin.org/articles/10.3389/fnins.2021.691788/fullFlávio Afonso Gonçalves MourãoLeonardo de Oliveira GuarnieriPaulo Aparecido Amaral JúniorVinícius Rezende CarvalhoEduardo Mazoni Andrade Marçal MendesMarcio Flavio Dutra Moraesapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/60673/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALA Fully Adapted Headstage With Custom Electrode Arrays Designed for Electrophysiological Experiments.pdfA Fully Adapted Headstage With Custom Electrode Arrays Designed for Electrophysiological Experiments.pdfapplication/pdf885330https://repositorio.ufmg.br/bitstream/1843/60673/2/A%20Fully%20Adapted%20Headstage%20With%20Custom%20Electrode%20Arrays%20Designed%20for%20Electrophysiological%20Experiments.pdfae5ab0bad51a676986d885a2e42f991dMD521843/606732023-11-08 19:19:32.323oai:repositorio.ufmg.br:1843/60673Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-08T22:19:32Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
