On the role of stigmergy in cognition
Correia, L.; Sebastião, A. M.; Santana, P.Cognition in animals is produced by the self- organized activity of mutually entrained body and brain. Given that stigmergy plays a major role in self-organization of societies, we identify stigmergic behavior in cognitive systems, as a common mechanism ranging from brain activity to social systems. We analyze natural societies and artificial systems exploiting stigmergy to produce cognition. Several authors ha...
Adenosine A(2A) receptor blockade reverts hippocampal stress-induced deficits a...
Batalha, V. L.; Pêgo, José M.; Fontinha, B. M.; Costenla, A. R.; Valadas, J. S.; Baqi, Y.; Radjainia, H.; Müller, C. E.; Sebastião, A. M.; Lopes, L. V.Maternal separation (MS) is an early life stress model that induces permanent changes in the central nervous system, impairing hippocampal long-term potentiation (LTP) and spatial working memory. There are compelling evidences for a role of hippocampal adenosine A(2A) receptors in stress-induced modifications related to cognition, thus opening a potential window for therapeutic intervention. Here, we submitted ...
Challenges in spintronic platforms for biomedical applications
Freitas, P. P.; Cardoso, F. A.; Martins, V. C.; Fernandes, Elisabete Ramos; Martins, S. A. M.; Dias, T.; Amaral, J. P.; Cardoso, S.; Germano, J.Integrated spintronic biochip platforms are being developed for portable, point-of-care, diagnostic and cytometric applications [1,2]. Hybrid systems incorporating magnetoresistive sensors are applied to neuroelectronic studies and biomedical imaging, namely magnetoencephalography and magnetocardiography. Lab-on-a-chip MR-based platforms are under development to perform biological studies at the single molecule...
