Neuronal Network Oscillations in the Control of Human Movement
… a process of disengagement from the existing network to enable the creation of functional assemblies required for movement. Importantly, I also demonstrate a novel neural signature of transient alpha synchrony, that occurs after preparatory desynchronisation, that underlies the recruitment of …

Determining how stable network oscillations arise from neuronal and synaptic mechanisms
… patterns are commonly mediated by neural networks that produce an oscillatory activity pattern, where different neurons maintain a relative phase relationship. This thesis examines the relationships between the cellular and synaptic properties that give rise to stable activity in the form …

The role of hyperpolarization-activated non-selective cation current in amygdala excitability and serotonin mediated effects.
… role in the rat brain, participating in network oscillations, temporal summation of synaptic inputs, and seizure development. Since hyperexcitability of the amygdala is related to anxiety and stress disorders, we investigated the role of Ih in amgydala excitability. In lateral amygdala …

Automated cell-targeted electrophysiology in vivo and non-invasive gamma frequency entrainment
… neurons in neural circuits give rise to network oscillations, whose frequencies are closely related to specific brain states.

Assessing Neuronal Synchrony and Brain Function Through Local Field Potential and Spike Analysis
<p>Studies of neuronal network oscillations and rhythmic neuronal synchronization have led to a number of important insights in recent years, giving us a better understanding of the temporal organization of neuronal activity related to essential brain functions like sensory processing and …

Signaling Mechanisms That Control Gap Junctional Coupling Between Retinal Neurons
… neuronal synchronization, signal averaging, network oscillations, and motor learning. Connexin 36 is strongly expressed in the retina, where it is an obligatory component of the high-sensitivity rod photoreceptor pathway. A fundamental requirement of the retina is to adapt to broadly varying …

The effects of cholinergic and dopaminergic neurons on hippocampal learning and memory processes
… neuromodulatory systems modulate hippocampal network activity, I first examined their effects on hippocampal local field potentials in urethane-anaesthetised mice. I demonstrated that optogenetic cholinergic activation suppressed slow oscillations, shifting brain activity to a state dominated …
