Various mechanisms of interaction which are intrinsic to neuronal populations exert profound influences on the dynamic behaviour of individual elements within the population and may markedly affect the behavior of such elements in response to pharmacological agents, af ferent inhibitory or excitatory drive, or other treatments that affect neu ronal activity.
A computational model was developed in which GPe neurons are represented as coupled phase oscillators influenced by experimentally derived phase-response curves and extrinsic inputs, showing that while the model captures general trends, discrepancies exist in peak amplitude and decay rates, suggesting that key biologic...
This manuscript distil theoretical approaches to emergence into a practical framework for assessing system behaviour focussed on “novelty” as a necessary condition for emergence and identifies a range of ways in which novelty can arise.

The effects of stimulation are dependent on the baseline state of the network, with the level of beta suppression dependent on the level of inhibition and the external drive, and networks with higher inhibition and lower drive show greater disruption of beta oscillations.

It is shown that L6CT neurons in mouse somatosensory cortex robustly signal the presence of tactile stimuli but are comparatively weak encoders of stimulus strength during a sensory detection task, suggesting that L6CT neurons are specialized less for representing fine sensory detail and more for signaling the occurren...

Determining the amount of information a neuron receives per unit of time is key to understanding brain connectivity and how neural networks encode and transmit information. In particular, estimating this information flow by distinguishing between excitatory and inhibitory synaptic contributions is critical to understan...

It is demonstrated that the vagus nerve (VN), a principal afferent pathway for interoceptive signaling, also affects PVT neuronal activity in mice, and plays a pivotal role in linking vagus nerve-related bodily states to emotional responses.
