Neural connectivity pathways

Neural connectivity pathways represent the structural and functional links between neurons and distinct brain regions, forming the basis of the nervous system's communication network (Sporns, 2011). These pathways consist of white matter tracts, which are bundles of myelinated axons, and synaptic connections that enable the integration of sensory, motor, and cognitive information (NIH, 2023). In various pathologies, such as Alzheimer's disease or schizophrenia, these pathways exhibit structural degradation or functional dysconnectivity, leading to cognitive and behavioral deficits (Fornito et al., 2015). While neural connectivity pathways is not a single druggable molecule, it serves as the framework within which specific molecular targets—such as ion channels, neurotransmitter receptors, and synaptic proteins—operate. Modern therapeutic approaches, including neuropharmacology and neuromodulation, aim to influence these pathways to restore healthy brain dynamics (Lozano et al., 2019). The study of these pathways, often referred to as connectomics, is essential for identifying how localized molecular changes translate into systemic brain dysfunction. Pharmacological agents often target specific nodes within these pathways to enhance synaptic plasticity or stabilize axonal integrity. Consequently, understanding the architecture of these pathways is vital for the development of precision medicine in neurology and psychiatry.

Not applicable. Neural connectivity pathways are anatomical and functional systems rather than discrete molecular targets; however, drugs modulate these pathways by acting on specific receptors, ion channels, or signaling molecules within the circuit (Lozano et al., 2019).
