ย Let’s break down the definitions ofย G proteinsย in general, and then the specificย Gi/o proteinย family. 1. The High-Level Overview: What are G Proteins? G proteins, orย guanine nucleotide-binding proteins, are a family of molecular switches that transmit signals from the outside of a cell to its interior. They are crucial components of a major signaling pathway used by […]

Oligodendrocyte precursor differentiation and remyelination describes the biological process by which the central nervous system (CNS) repairs damage to the protectiveย myelin sheathย that surrounds nerve fibers (axons).ย This process is critical for restoring efficient nerve signal transmission and preventing permanent axonal degeneration in demyelinating conditions like multiple sclerosis (MS) and spinal cord injuries (SCI).ย The Process […]
The Regulatory Pathway for High-Risk Neuro-Electric Devices: From Preclinical to Post-Market
The Regulatory Pathway for High-Risk Neuro-Electric Devices: From Preclinical to Post-Market The regulatory pathway for a Class III neuro-electric device, such as an implantable BCI, is a rigorous, evidence-driven process overseen by the U.S. Food and Drug Administration. The journey typically begins with extensive preclinical testing, which must establish a reasonable assurance of safety. This […]
The Signal Acquisition Frontier: ECoG, Utah Arrays, and Neuropixels in BCI
The Signal Acquisition Frontier: ECoG, Utah Arrays, and Neuropixels in BCI The fidelity of a BCI is fundamentally constrained by its signal acquisition method. Electrocorticography, which places electrode grids on the surface of the dura mater, provides a middle-ground resolution, capturing local field potentials and high-frequency broadband activity from small populations of neurons. ECoG offers […]
ย Decoding Neural Intent: From Cortical Firing Patterns to BCI Commands
Decoding Neural Intent: From Cortical Firing Patterns to BCI Commands The fundamental challenge in motor Brain-Computer Interfaces is accurately decoding movement intention from neural signals. Invasive BCIs often rely on recordings from microelectrode arrays implanted in the primary motor cortex, which capture the firing rates of populations of neurons. Each neuron exhibits a tuning property, […]
Astrocytic TNF-ฮฑ and the Homeostatic Control of Synaptic Scaling
Astrocytic TNF-ฮฑ and the Homeostatic Control of Synaptic Scaling Homeostatic plasticity operates on a slower timescale than Hebbian plasticity to stabilize neuronal firing rates across a network. Synaptic scaling is a key homeostatic mechanism that globally adjusts synaptic strength in a multiplicative manner, and glial-derived Tumor Necrosis Factor-alpha is a critical mediator of this process. […]
Rho GTPase Signaling in Structural Plasticity and Dendritic Spine Remodeling
Rho GTPase Signaling in Structural Plasticity and Dendritic Spine Remodeling Structural plasticity, the physical reshaping of dendritic spines, is the anatomical correlate of long-term information storage. The dynamics of the actin cytoskeleton are the primary driver of these morphological changes, and the Rho family of small GTPasesโRhoA, Rac1, and Cdc42โserves as the master regulator of […]
