Exploring the relationship between attention, motivation and BCI task performance

, 2023
reservedThis thesis aims to explore the relationship between five psychological and cognitive variables, i.e., selective attention, sustained attention, reaction time, motivation and locus of control, and BCI task performance.

On the stimulus duty cycle in steady state visual evoked potential [PDF]

, 2014
Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly

Multiresolution analysis over simple graphs for brain computer interfaces [PDF]

, 2013
Objective. Multiresolution analysis (MRA) offers a useful framework for signal analysis in the temporal and spectral domains, although commonly employed MRA methods may not be the best approach for brain computer interface (BCI) applications.

Engel BCI-algebras: an application of left and right commutators [PDF]

, 2021
summary:We introduce Engel elements in a BCI-algebra by using left and right normed commutators, and some properties of these elements are studied. The notion of $n$-Engel BCI-algebra as a natural generalization of commutative BCI-algebras is introduced,

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Monitoraggio dell'attività cerebrale tramite brain-computer-interface(BCI) [PDF]

, 2022
Un’interfaccia cervello-computer (in inglese, Brain-Computer Interface, abbreviato in BCI, o anche Brain-Machine Interface, BMI) è un sistema di comunicazione in cui i messaggi o i comandi che l’utente normalmente invia per agire sul mondo esterno non ...

Long-term effect on EEG sensorimotor responsiveness to motor imagery after a BCI training for stroke rehabilitation

, 2023
Previous studies demonstrated the efficacy of EEG-Brain-Computer Interfaces based on Motor Imagery (MI-BCI) in post stroke functional motor recovery of upper limbs [1]; however, the maintenance of such effects in the long-term is still partially ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Ethical and Safety Challenges of Implantable Brain-Computer Interface [PDF]

Interdisciplinary Description of Complex Systems
The study of brain-computer interfaces (BCIs) holds immense potential across various fields, particularly in Human-Robot Interaction, where invasive BCIs offer precise and direct communication between the human brain and robotic devices. However, the use
