Summary
Cortical spreading depression (CSD) dynamics were modeled, revealing that neurovascular coupling influences CSD front propagation and pattern formation. This research shows that vascular coupling and local regulation create stationary Turing-like patterns during CSD events.
Area of Science:
- Neuroscience
- Computational Biology
- Physiology
Background:
- Cortical spreading depression (CSD) involves neuronal hyperactivity followed by depression, impacting conditions like migraines and stroke.
- The complex spatiotemporal dynamics of CSD formation and evolution remain poorly understood despite existing models.
- Neurovascular coupling and cerebral blood flow changes are implicated in CSD but their precise dynamical roles require further investigation.
Purpose of the Study:
- To investigate the dynamical consequences of incorporating neurovascular coupling and blood flow redistribution into a mathematical model of CSD.
- To analyze how these new pathways affect the formation, propagation speed, and two-dimensional pattern features of the CSD front.
- To elucidate the mechanisms behind complex pattern formation during CSD events.
Main Methods:
- Development of a mathematical model for cortical spreading depression incorporating neurovascular coupling and cerebral blood flow.
- Simulation of the model to analyze changes in CSD front dynamics, including propagation speed and pattern formation.
- Examination of two-dimensional pattern evolution under the influence of vascular-mediated spatial coupling and local regulatory mechanisms.
Main Results:
- The model demonstrates that neurovascular coupling significantly alters CSD front propagation and pattern formation.
- The interplay between vascular-mediated spatial coupling and local regulatory mechanisms leads to the emergence of stationary patterns.
- Specifically, the study identified the formation of stationary Turing-like patterns during CSD events due to these combined effects.
Conclusions:
- The inclusion of neurovascular coupling and blood flow dynamics provides crucial insights into CSD mechanisms.
- The formation of stationary Turing-like patterns is a key emergent property resulting from the interaction of vascular coupling and local regulation.
- This research advances our understanding of the complex spatiotemporal dynamics underlying CSD and related neurological phenomena.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

25.5K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

6.2K
There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
