Conectividade cerebral como característica para classificar tarefas motoras de mesmo segmento corporal: Interação humano-robô
… later. Differences were found only in beta and gamma rhythms of EEG. Finally, both DTF and PDC were applied separately as features in ANN to classify between the imagination, movement and observation of elbow flexion and extension, and at rest. The highest accuracy using DTF was 90.6% achieved …

Aplicação da entropia de permutação A sinais EEG durante estimulação dinâmica de cenário virtual
… Hz. The analysis performed in the beta1 neural rhythm indicated a change in the Complexity of this rhythm, but only on leads O1 and O2. Theta, alpha and beta2 rhythms presented significant variation in the occipital, parietal and central derivations; again the frontal leads did not present a …

Large-scale neural recordings and biophysical models for inferring network mechanisms of ketamine anesthesia
… all therapeutic doses, ketamine generates robust gamma oscillations between 30-80 Hz that are typical of active, structured cognition; yet, under ketamine, gamma oscillations persist into profound sedation and anesthetic unconsciousness. Here, I use experimental and computational approaches to …

Συγκριτική μελέτη της ρυθμικής δραστηριότητας που αναπτύσσεται σε τομές ραχιαίου και κοιλιακού ιπποκάμπου αρουραίου με αγωνιστή υποδοχέων ακετυλοχολίνης
Οι in vivo θ και γ ρυθμοί στον ιππόκαμπο συνυπάρχουν και θεωρείται ότι συμμετέχουν στην διαδικασία δημιουργίας και ανάκλησης των μνημονικών αναπαραστάσεων. Σε τομές ιπποκάμπου in vitro, βρήκαμε όμως ότι διαφοροποιείται η ικανότητα επαγωγής αυτών των ρυθμών στο κοιλιακό σε σχέση με το ραχιαίο άκρο …

Mechanisms of hippocampal relational memory binding
… were subject to an extrinsically generated theta rhythm, and a locally generated gamma rhythm. This allowed the model to do more than simply generate conjunctions corresponding to previous inputs. First, the model treats dynamics of the entire entorhinal cortex as a superposition of the activity …
