Temporal dynamics of MEG phase information during speech perception: Segmentation and neural communication using mutual information and phase locking
… frequency information is utilized to facilitate communication between brain areas thought to underlie speech perception. Distinct auditory/speech networks that operated exclusively using these frequencies were revealed, suggesting a privileged role for these timescales for neural communication …

Massively parallel neural computation
… focusses on real-time computation of large neural networks using the Izhikevich spiking neuron model. Neural computation has been described as “embarrassingly parallel” as each neuron can be thought of as an independent system, with behaviour described by a mathematical model. However, the …

A study of electrical aspects of neural conduction with an emphasis on the phenomenon of pain
A study of the electrical nature of neural communication is performed. The study provides a background for the evaluation of an electrical mechanism, set forth by the author, as a possible explanation for the effect of acupuncture. The electrical and biological processes involved in the conduction …

Generative models of brain connectivity for population studies
… Such relationships inform us about patterns of neural communication and may enhance our understanding of neurological disorders. This thesis proposes a generative framework that uses anatomical and functional connectivity information to find impairments within a clinical population. Anatomical …

Assessing the oscillatory properties of functional connections between sensory areas during crossmodal illusions: A correlational and causal investigation.
… (auditory-to-visual or somatosensory-to-visual) neural connections favouring optimal, directional neural communication and integration between the senses.

A chronically implantable neural device for on-demand microdosing of deep brain structures
… are due to a loss in synchrony in a specific neural network. Effective treatments must seek to attenuate these network dynamics to establish normal neural communication. However, current treatments lack the spatiotemporal resolution to target networks with such specificity. The 'Injectrode' …

Stability of thin-film PEDOT:PSS electrodes for neuromodulation
… pathways, improving our understanding of neural communication and treatment of neurological disorders.

Phase- and amplitude-coupling are tied by an intrinsic spatial organization but show divergent stimulus-related changes
… (FC), thought to provide a window into neural communication, has become a core focus in the study of brain function and cognition. However, there is no consensus on how to conceptualize large-scale FC in electrophysiology. Phase coupling (PhC), defined as coupling between the phases of …

Differentiating noise and modulators in artificial neural networks
Research in Computational Neural Networks is currently taking place at many different levels; from coarse-grain symbolic models to fine-grain representations of neurons and cell processes. One feature that the different approaches share, is that they are all in relative infancy. Thus, most research …

Metabotropic glutamate receptors as targets for antiepileptic drug therapy: a behavioral and electroencephalographic analysis
… signalling at these channels can alter normal neural communication and can have negative side effects, including cognitive dysfunction and fatigue, which are among the most common complaints from patients. Given the high rate of drug-resistant patients, and the high rate of deleterious side …

The gut microbiota in depression
… in neuroscience. Neuroimmune, neuroendocrine and neural communication pathways exist between host and microbe. These pathways are components of the brain-gut-microbiota axis and preclinical evidence suggests that the microbiota can recruit this bidirectional communication system to modulate brain …

Computational tools for monitoring neural connectivity using calcium imaging
… light-activated manipulation and monitoring of neural activity that offer powerful alternatives to traditional electronic and chemical methods. Along with light-evoked activity, many technical advancements have been made that allow for facilitated optical delivery, activation, and recording of …

The role of estradiol in astrocyte and neuron communication
… are now appreciated for their active role in neural communication. The “tripartite synapse” depicts the bidirectional communication between the presynaptic, postsynaptic neuron and the neighboring astrocyte. An important characteristic of this astrocyte-neuron communication is the astrocyte …
