Abstract: A broad number of studies have used multivariate pattern analysis (MVPA) to track spatial representations such as position from human brain activity. While decoding spatial features has provided important insights on how working memory tracks representations, some studies have demonstrated that decoding spatial features can also be influenced by eye movements and spatial attention. This implies that EEG signals can be biased by the oculomotor system (e.g., is MVPA detecting neural representations or different eye-movement patterns?). Thus, decoding elements that are not defined by spatial factors and/or eye movements, like colour, can be an important proof-ofprinciple that neural representation can be decoded from electroencephalography (EEG). Even though few studies have decoded colour from EEG, it is still unclear whether using different features from EEG signals (e.g., Oscillations and ERPs) may carry different representations (e.g., position vs colour), and if different pre-processing methods and machine learning techniques may improve accuracy levels. Therefore, the purpose of this project is to determine whether colour and position can be decoded separately from various features of human electroencephalography (EEG) using different machine learning methods. Resumen: Varias investigaciones han utilizado el análisis de patrones multivariados (MVPA) para rastrear representaciones espaciales desde la memoria de trabajo humana como la posición de un objeto. Si bien la decodificación de características espaciales ha brindado información importante sobre cómo la memoria de trabajo rastrea representaciones visuales, algunos estudios han demostrado que la decodificación de características espaciales también puede verse influenciada por los movimientos oculares y la atención espacial. Esto implica que las señales de EEG pueden estar sesgadas por el sistema oculomotor (p. ej., ¿MVPA detecta representaciones neuronales o diferentes patrones del movimiento ocular?). Por lo tanto, la decodificación de elementos que no están definidos por factores espaciales y/o movimientos oculares, como el color, puede ser una importante prueba de que la representación neuronal se puede decodificar a partir de la electroencefalografía (EEG). Aunque algunos cuantos estudios han decodificado el color usando EEG, todavía no está claro si el uso de diferentes características de las señales de EEG (p. ej., oscilaciones y ERP) puede tener diferentes representaciones (p. ej., posición frente a color), y si los diferentes métodos de preprocesamiento y aprendizaje automático pueden mejorar los niveles de precisión. Por lo tanto, el propósito de este proyecto es determinar si el color y la posición se pueden decodificar utilizando varias características de la electroencefalografía humana (EEG) y diferentes métodos de machine learning.

Abstract: Background: Deep brain stimulation (DBS) surgery is a treatment in the advanced stage of Parkinson's disease (PD). Despite close follow-up, multiple evaluations, and several months of timeconsuming programming sessions, the clinical response may not be optimal in some cases. Imageguided programming (I-GP) could help optimize programming sessions with better clinical outcomes. Objective: To evaluate clinical and quality of life (QoL) outcomes with I-GP in PD patients with DBS of the subthalamic nucleus (STN) and suboptimal clinical improvement and refractory symptoms to conventional clinical programming. Methods: A prospective study in 16 patients with a diagnosis of PD with STN-DBS and remaining adverse effects or symptoms despite a clinical programming adjustment. We simulate potentially effective stimulation based on volume tissue activated (VTA) using commercially available software tools. Clinical outcomes were assessed with motor and quality of life scales. Results: The most frequent suboptimal symptom was gait disorder 33.3% (n=9), residual motor symptoms 25.9%(n=7), and speech 25.9%(n=7). Statistically significant results (p=0.001) were found after I-GP with change in the global Deep Brain Stimulation – Impairment score (41%), The 8- item version of the Parkinson's Disease Questionnaire (47%), EuroQol visual analogue scale (62%), and motor scale (24%). Conclusions: In suboptimal cases of patients with PD and STN-DBS, especially with ongoing and residual motor symptoms, I-GP could be useful to optimize the programming of DBS and improve patients' QoL.

Abstract: Liquid Homes is a study about migration based on social sciences theories, contemporary films, and my personal experiences. Within this understanding of migration, the concept of Home is identified as a physical and imaginary place pertaining to all individual of society, to which civil rights and urbanism are related, and which is in constant tension in a global system because of the processes of modernity, the development of industrialisation and capitalism. In this text an analysis of contemporary migration is proposed throughout films produced during the European migrant crisis (2015- ), to do a critical analysis about the approach and representation in films of the migrant population and to suggest recognition, humanism and familiarity with migrant communities and their civil rights. It was my last evening in Lisbon crossing the Tejo river in a ferry going to the other side of the city. We came over the second floor and sat down on the chairs with the windows facing the sunset. She was looking at messages on her mobile phone, while I was looking at the colour and shadows projected on her face. Suddenly she surprised and said: A bomb has exploded in the main harbour of Beirut. It is when this story about Liquid Homes started. Until this moment I had not any mental map of Lebanon, I knew it was part of the „Middle East” region with an Arabic culture. She told me she has some friends in Beirut because she was doing her field based research thesis in a Palestinian Refugee Camp called Shatila. I guess that the mixture of feelings between her and me at that moment have impressed in my memory the need to understand Shatila. Feelings about the beginning and the finishing of new stages of our lives, moving again of (from/to) homes, in different non-established houses, around different people, different languages and geographies. In my case, feelings of coming back to a place with legal rules made to make it the hardest for foreigners and for their establishment of a normal life, a hostile place in an economic way, where you are not welcome if you are not coming to produce or give money to the society. With the time I have understood that Shatila is a “Liquid Home” for its inhabitants. As a “new city” is for migrants. A “Liquid Home” is a place for waiting - for the return or for continuing towards the desired land and the desired lifestyle, with the difference that for people in Shatila and their parents before them were born there, but they do not have legal right over the land nor over pretty much anything in the place they inhabit. I identify a liquid home as the space constructed to be easily changed according to political international movements, according to the economic profit of international relationships under the flagship of solidarity. An artificial urbanization made with modular materials to be easily moved and articulated, where the architecture of the houses, of the streets, of the daily human relations can be withdrawn from their users as an expropriation not just of their houses but as well of their civil rights. As a nobody, who occupy the territory, liquid homes are a result of liquid societies, a modernisation of the urban lifestyle understood within Zygmunt Bauman’s analysis of the late modernity, where the reality of the inhabitants of the society is made to allow constant and contrasting changes. The objective of this writing is to describe how the phenomenon of migration, cities and citizenship have been told in cinema from 2015 until now, and to analyse different approaches, methods of research and filming migration and the noncitizenship, using cinema as a cultural expression that reflects the modern thinking and troubles of a migration society. I will also use personal notes as an ethnographic research method, reflecting my experience as a foreigner and all that not having a citizenship in the place where I live has meant.
