The examples of the latter, include interaction of oligomeric Aß or misfolded tau with cell surface receptors, intracellular signaling molecules or scaffold proteins, which leads to the deterioration of synaptic structure and function causing Alzheimer’s disease (AD) ( Chen et al., 2019). The synapses may fail to transmit signals due to the depletion of neurotransmitters or external changes in membrane/ion channel activity. ![]() Neurons transmit signals to communicate predominantly via synapses. Obtained results may lead to better understanding of changes in large-scale pattern formation during progression of neuro-degenerative diseases targeting synaptic transmission. We show that this is because activity-dependent synaptic failure homogenizes the activity levels in the network creating a dynamical substrate for the observed coherence increase. We show that synaptic failure may not only lead to the loss of coherence but unintuitively also can facilitate its emergence. We found that the two structures have significantly different dynamical properties. We defined scale-free network structures based on the dominating direction of the connections at the hub neurons: incoming and outgoing. We studied two types of synaptic failure: activity-independent and targeted, activity-dependent synaptic failure. Here, we investigate how synaptic failure can affect spatio-temporal dynamics of scale free networks, having a power law scaling of number of connections per neuron – a relatively few neurons (hubs) with a lot of emanating or incoming connections and many cells with low connectivity. In addition, hubs in cortical networks are shown to be more vulnerable to amyloid deposition because of their higher activity within the network, causing decrease in coherence patterns and eventually Alzheimer’s disease (AD). It has been speculated that anesthetics regulate conscious state by affecting synaptic transmission at these network hubs and subsequently reducing overall coherence in the network activity. As a result, the activity of these highly connected neurons can be significantly affected. A number of studies have suggested that synaptic failure may preferentially target neurons with high connectivity (i.e., network hubs). Therefore, synaptic failure may critically impair information processing in the brain and may underlie many neurodegenerative diseases. The communication of neurons is primarily maintained by synapses, which play a crucial role in the functioning of the nervous system. 2Department of Physics, University of Michigan, Ann Arbor, MI, United States.1Biophysics Program, University of Michigan, Ann Arbor, MI, United States.įrequently asked questions about the e-prescribing mandate are answered at the following.
