calcium imaging
التصوير بالكالسيوم

Fluorescence-based method monitoring neuronal activity via calcium ion concentration changes.

Modalities
Calibration
المعايرة

Initial data recording used to train algorithms and align user-system parameters.

Protocols and paradigms
Capacitive Electroencephalography (cEEG)
تخطيط الدماغ الكهربائي السعوي

Non-contact EEG method utilizing capacitive sensors, enhancing user comfort and ease of setup.

Modalities
channel
القناة

The pathway through which the brain signal is collected, transmitted, and processed

System components
Classifier
المصنِّف

A machine learning algorithm that learns to assign a label (e.g., move left or select letter B) to a pattern of neural activity. Common examples include

AI and Machine Learning
click-evoked auditory evoked potential
الجهد المُثار سمعياً بالنقرة

An auditory evoked potential in response to a click stimulus, which is a brief, sharp sound used in auditory testing.

Protocols and paradigms
clinical trial
المحاولة/التجربة السريرية

A study involving multiple subjects that assesses the efficacy of a proposed intervention

Experimental designs and setups
clinical trial session
جلسة المحاولات/التجارب السريرية

A specific time period during which a subject receives an intervention or undergoes an assessment or both.

Experimental designs and setups
closed-loop
الحلقة المغلقة

A characteristic of a system whose control action is dependent on the output of the task and its deviation from a reference or ideal state.

Feedback and stimulations
Cognitive Load
العبء المعرفي

The amount of mental effort and concentration required from the user to operate the BCI. A primary goal of BCI design is to minimize this load.

Feedback and stimulations
Cognitive Security
الأمن المعرفي

Protecting neural data from cyberattacks, manipulation, or information leaks.

Ethical Governance
collaborative brain-computer interface
الترابط الدماغي الحاسوبي التعاوني

a BCI system that combines brain signals from several people in order to perfrom a task.

Basic concepts and types
Common Spatial Patterns (CSP)
الأنماط المكانية المشتركة

widely used spatial filtering algorithm, especially in motor imagery BCIs. It is designed to find optimal projections of the EEG data to maximize the variance between two different mental tasks (e.g., imagining left vs. right-hand movement).

Signal processing and analysis
competitive brain-computer interface
الترابط الدماغي الحاسوبي التنافسي

A BCI system that incorporates brain activities from multiple tasks where sets of users compete with each other, with the system determining the winner based on the quality or speed of each party's neural signals.

Basic concepts and types
Compliance Rate
معدل الالتزام (أو نسبة التقيّد بالتجربة)

Percentage of experimental instructions or tasks correctly completed by subjects, indicating protocol adherence.

Experimental designs and setups
component
المكون

A distinguishable and separable neural signal source or pattern identified within the raw neural

Signal processing and analysis
Consent Withdrawal
سحب الموافقة

Ensuring participants have the right and mechanism to withdraw consent at any stage of research or application.

Ethical Governance
Continuous Feedback
التغذية الراجعة المستمرة

Real-time feedback presented constantly during an ongoing BCI control or training session for ongoing error correction.

Feedback and stimulations
Control Group
المجموعة الضابطة

Group of subjects not receiving the primary experimental manipulation, serving for comparison to assess effects.

Experimental designs and setups
Convolutional Neural Network (CNN)
الشبكة العصبية الالتفافية

A deep learning model effective at detecting spatial structures within EEG or neuroimaging data.
