    Neurobiological mechanisms involved in the loss of control over food intake 

    Domingo Rodriguez, Laura (Date of defense: 2020-01-17)

    The easy access to palatable foods is a major contributing factor for compulsive eating and development of food addiction, a disorder closely linked to obesity and binge eating disorder. The concept of food addiction is ...

    Neurobiological substrates involved in the behavioural alterations induced by MDMA and THC administration in mice 

    Viñals Álvarez, Xavier (Date of defense: 2015-04-09)

    El cànnabis i l’èxtasi són dues drogues d’ús recreatiu, les quals usualment es solen consumir de forma conjunta. Degut al seu ús combinat, resulta difícil esclarir les conseqüències que té cada droga a nivell neurobiològic. ...

    Neurodynamical modeling of arbitrary visuomotor tasks 

    Loh, Marco (Date of defense: 2008-02-11)

    El aprendizaje visuomotor condicional es un paradigma en el que las asociaciones estímulo-respuesta se aprenden a través de una recompensa. Un experimento típico se desarrolla de la siguiente forma: cuando se presenta un ...
