Lab meetings
The lab meetings are the appropriate internal forum of open discussion (science projects, new ideas, administrative issues, etc.), and allow all members to be informed of our current research efforts, organization, and activities.
These meetings are organized by Catarina Duarte and Marco Simões.
The meeting schedule is updated using the Lab meetings calendar and the grupoMCB mailing list. Discussions regarding lab meetings are maintained in Discord channel #lab-meetings.
The first meeting each month starts with a short presentation of member arrivals and departures, delivered by the lab meeting organizers, and a 3-minute pitch delivered by the author of each newly published paper. The author should contact the lab meeting organizers in advance to schedule and organize a presentation.
Lab meetings are usually held weekly on Friday at 14h30 in the meeting room at ICNAS, Sub-Unidade 1 of FMUC, or via Zoom. They last approximately one hour and are open to the entire CIBIT community.
For an updated list of the past and upcoming lab meetings, please see the here.

Excitation Inhibition Balance in Health and Disease
In this presentation, I will make a demonstration of my proposed PhD defense presentation which is supposed to be held on 20-Sep. We studied the excitation-inhibition balance disruption in two disorders, namely type 2 diabetes and drug-resistant epilepsy. In this work, we discuss the relationship between occipital GABA concentration or BBB integrity and visual performance in T2DM. We then discuss the role of the GABAergic system in physiologic brain oscillations and we finish with a discussion on the role of the GABAergic system in epileptogenesis.

Towards Open science: Collaborative tools part 2
Continuation of last week’s discussion on the lab wiki. Today we will have a hands-on session on how to create, manage and roll back content.
Continuity in research group knowledge is critical. A lab wiki, can bridge gaps between researchers. A lab wiki aims to represent a collaborative resource that can contain tutorials, group-specific directions, or links to resources.
Speaker: Alexandre Sayal, Bruno Direito, Hugo Quental, João Duarte, João Pereira et al.

Towards Open science: Collaborative tools
Following-up on our discussion on data management, we will present a web application that aims to document, archive, share best practices, materials, and/or policies.
Continuity in research group knowledge is critical. A lab wiki, can bridge gaps between researchers. A lab wiki aims to represent a collaborative resource that can contain tutorials, group-specific directions, or links to resources [1].

An introduction to Data Management Plans
O conhecimento é de todos e para todos” [1] É cada vez mais amplo o consenso que define como prioridade o compromisso com os princípios e práticas da ciência aberta. E neste sentido, importa reforçar que a ciência aberta é mais do que a partilha e acesso aberto de dados ou publicações, é a abertura do processo científico enquanto um todo. “A implementação da Ciência Aberta envolve a incorporação de metodologias, ferramentas e práticas de natureza colaborativa e requer o compromisso dos diversos agentes implicados na produção, divulgação e utilização do conhecimento.” [2] Um dos pilares que sustenta a Ciência Aberta é o planeamento da gestão dos dados resultantes de investigação (as instituições nacionais vão tornar obrigatório este processo em breve). Este planeamento deve considerar o ciclo de vida dos dados, que vai desde a sua criação até ao seu armazenamento e partilha. [3] Os Planos de Gestão de Dados (DMP) são fundamentais para descrever os processos envolvidos no ciclo de vida dos dados e alavancam a sua reutilização, e interoperabilidade. Esta semana, o investigador João Cardoso junta-se a nós, para discutir estes conceitos, mais-valias da definição de DMP, a sua implementação e falar um pouco acerca da sua investigação nesta área.
Speaker: João Cardoso
João Cardoso, é um investigador do INESC-ID desde 2013. O seu trabalho de investigação incide na área da gestão de dados de investigação, com particular foco na automação de actividades de gestão de dados baseada em planos de gestão de dados acionáveis por máquinas. Desde 2019 que colabora com o grupo de trabalho “DMP Common Standard for Machine-actionable Data Management Plans” da Research Data Alliance. É também um membro da Infraestrutura BioData.pt desde 2015, sendo um dos formadores do programa de cursos “Ready For BioData Management?”. João Cardoso tem um MSc. em Engenharia de Telecomunicações e Informática do IST (2013), e é actualmente aluno de PhD no programa de Engenharia Informática e de Computadores.

CAT12 vs Freesurfer cortical thickness comparison
A survey conducted by nature to 1576 scientists revealed that 70% of them could not reproduce results previously reported. This might have multiple causes including a low sample size of the studies conducted. Moreover, in the neuroimaging field the choice of the software might impact the results obtained. Different softwares might lead to different conclusions. Each one of the softwares has a different algorithm for each one of these steps, which might lead to the introduction of specific artifacts in the data. CAT12 and Freesurfer are established softwares used in the neuroimaging field to preprocess the data. In this study the cortical thickness extracted from both softwares is compared using a large amount of structural images. The results show that some brain regions have a low reproducibility in both softwares at the interindividual and intraindividual level.
