Simultaneous EEG Monitoring During Transcranial Direct Current Stimulation Pedro Schestatsky1,2,3, Leon Morales-Quezada3,4, Felipe Fregni3 1Programa de Pós-Graduação em Ciências Médica, Universidade Federal do Rio Grande do Sul, 2Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES), 3Laboratory of Neuromodulation, Department of Physical Medicine & Rehabilitation, Spaulding Rehabilitation Hospital and Massachusetts General Hospital, Harvard Medical School, 4De Montfort University Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has shown initial therapeutic effects in several neurological conditions. The main mechanism underlying these therapeutic effects is the modulation of cortical excitability. Therefore, online monitoring of cortical excitability would help guide stimulation parameters and optimize its therapeutic effects. In the present article we review the use of a novel device that combines simultaneous tDCS and EEG monitoring in real time.
Blood Collection for Biochemical Analysis in Adult Zebrafish Gabriela L. Pedroso1,2, Thais O. Hammes1,2, Thayssa D.C. Escobar1, Laisa B. Fracasso1, Luiz Felipe Forgiarini1, Themis R. da Silveira1,2 1Hospital de Clínicas de Porto Alegre, Centro de Pesquisa Experimental Laboratório de Hepatologia e Gastroenterologia Experimental, 2Universidade Federal do Rio Grande do Sul, UFRGS. Porto Alegre, RS, Brasil This paper presents a technique for collection of blood from the dorsal aorta of Zebrafish. It also provides instructions for obtaining serum for use in biochemical analyses, such as tests for determining cholesterol and triglyceride levels.
