Connectomics is a field of neuroscience that focuses on the comprehensive mapping and study of neural connections in the brain at various scales, ranging from the microscale of individual neurons and synapses to the macroscale of functional and structural connectivity between different brain regions.  1. Definition:    - Connectomics is the production and analysis of connectomes, which are detailed maps of neural connections within the nervous system of an organism, including the brain.    - Connectomics aims to understand the structural and functional wiring of the brain, elucidating how neural circuits are organized, how information flows between brain regions, and how connectivity patterns relate to brain function and behavior.   2. Scale:    - Connectomics can be studied at multiple scales, encompassing the microscale of individual neurons and synapses, the mesoscale of neural circuits and brain regions, and the macroscale of large-scale brain...

Functional brain networks refer to the interconnected system of brain regions that exhibit synchronized neural activity and functional connectivity during specific cognitive tasks or at rest.  1. Definition:    - Functional brain networks are patterns of coordinated neural activity among different brain regions that work together to support specific cognitive functions, such as attention, memory, language, and emotion regulation [T5].    - These networks are identified using techniques like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), which measure changes in blood flow or electrical activity to infer functional connections between brain regions.   2. Resting-State Networks (RSNs):    - Resting-state networks (RSNs) are functional brain networks that exhibit synchronized activity even in the absence of a specific task, reflecting the intrinsic organization of the brain's functional architecture. ...

A brain network refers to the interconnected system of neural pathways and regions in the brain that work together to support various cognitive functions and behaviors.  1. Definition:    - A brain network is a complex web of interconnected brain regions that communicate and collaborate to perform specific functions, such as sensory processing, motor control, memory, emotion regulation, and higher-order cognitive processes.    - These networks consist of both structural connections (anatomical pathways) and functional connections (patterns of neural activity) that enable information processing and integration across different regions of the brain.   2. Functional Brain Networks:    - Functional brain networks are identified using techniques like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to map patterns of synchronized neural activity across different brain regions.    - Resting-state networks (RSNs) ar...

Brain network modulation refers to the process of influencing or altering the connectivity and activity patterns within the brain's functional networks.  1. Definition:    - Brain network modulation involves interventions or treatments that target specific brain regions or networks to induce changes in their functional connectivity, activity levels, or communication patterns.    - The goal of brain network modulation is to restore or optimize the balance and coordination of neural activity within and between different brain regions, ultimately leading to improved cognitive or behavioral outcomes.   2. Therapeutic Interventions:    - Various therapeutic interventions, such as pharmacotherapy, psychotherapy, neuromodulation techniques (e.g., transcranial magnetic stimulation, deep brain stimulation), and lifestyle interventions (e.g., exercise, mindfulness practices), can modulate brain networks in individuals with neuropsychiatric disorders like de...
