Chronic stress disrupts neural coherence between cortico-limbic structures
Dias, Nuno S.; Oliveira, João Filipe; Correia, Mariana; Gama-Pereira, Filipa; Sardinha, Vanessa Morais; Lima, Ana; Oliveira, Ana FilipaChronic stress impairs cognitive function, namely on tasks that rely on the integrity of cortico-limbic networks. To unravel the functional impact of progressive stress in cortico-limbic networks we measured neural activity and spectral coherences between the ventral hippocampus (vHIP) and the medial prefrontal cortex (mPFC) in rats subjected to short term stress (STS) and chronic unpredictable stress (CUS).

Cognitive intervention protocol for age-related memory impairments
Portugal, Ana Maria; Ferreira, Daniela Silva; Reis, Joana Santos; Pinho, Francisco; Dias, Nuno S.With the number of elderly people increasing tremendously worldwide, comes the need for effective methods to maintain or improve older adults' cognitive performance. Using continuous neurofeedback, through the use of EEG techniques, people can learn how to train and alter their brain electrical activity. A software platform that puts together the proposed rehabilitation methodology has been developed: a digital...
