Brain Networks
Neuroscience of connectivity — nodes, edges, synapses, resting networks.
Mechanisms
Synapses as electrical and chemical junctions
Two transmission modes in one junction type — speed and modulation share an address.
The entire neuronal network is connected by special junctions called "Synapses" and they can be both electrical and chemical, passing the signals throughout the body.
Why it matters
Two transmission modes in one junction type — speed and modulation share an address.
Use when: When a system needs both fast sync and slow chemistry at the same interface.
Evidence
DMN more active at rest than in task
Default is not idle — rest has its own active coalition.
The DMN is a network of brain regions that is more active at rest than during task performance [20].
Why it matters
Default is not idle — rest has its own active coalition.
Use when: When "doing nothing" is treated as neural silence.
Contradictions
No physical wire between neurons
Network without continuous material link — junction, not cable.
The network of neurons builds the foundation of the entire nervous system but there is no specific physical connection between two neurons.
Why it matters
Network without continuous material link — junction, not cable.
Use when: When "wired" brains need the synaptic gap restored.
Definitions
Brain communication as pathway network
Cognition is framed as inter-region traffic, not a single GPU in the skull.
BC refers to the intricate network of neural pathways that facilitate communication between different brain regions, essential for cognition, behavior, and perception.
Why it matters
Cognition is framed as inter-region traffic, not a single GPU in the skull.
Use when: When someone still talks about "the brain center for X" as a lone island.
Nodes and edges as the connectivity grammar
Graph language is not metaphor — it is the measurement frame.
Here, two important concepts in the network connectivity of the brain are nodes and edges.
Why it matters
Graph language is not metaphor — it is the measurement frame.
Use when: When translating brain talk into network science without mysticism.
