Cholinergic modulation of the CAN current may adjust neural dynamics for active memory maintenance, spatial navigation and time-compressed replay

Frontiers in Neural Circuits, 2012
Suppression of cholinergic receptors and inactivation of the septum impair short-term memory, and disrupt place cell and grid cell activity in the medial temporal lobe (MTL). Location-dependent hippocampal place cell firing during active waking, when the

Preparatory neuronal activity in ALM is decreased, but remains significant in quiet trials devoid of movements.

, 2022
(A) Larger delay period activity of ALM RS neurons in Active versus Quiet hit trials. Left: baseline-subtracted (1 second prior to whisker onset) population firing rate (mean ± SEM) overlaid for Quiet (blue) and Active (red) hit trials in Expert mice ...

Drifting states and synchronization induced chaos in autonomous networks of excitable neurons.

Frontiers in Computational Neuroscience, 2016
The study of balanced networks of excitatory and inhibitory neurons has led to several open questions. On the one hand it is yet unclear whether the asynchronous state observed in the brain is autonomously generated, or if it results from the interplay ...

Unraveling the role of collective bursting neurons, quiet waking, and structural plasticity in memory consolidation using a computational approach [PDF]

, 2023
editorial reviewedWhen memorizing new information, it is commonly accepted that breaks associated with brain rest can improve performance. We investigate this hypothesis using a computational approach.

Cholinergic Signals in Mouse Barrel Cortex during Active Whisker Sensing

Cell Reports, 2014
Summary: Internal brain states affect sensory perception, cognition, and learning. Many neocortical areas exhibit changes in the pattern and synchrony of neuronal activity during quiet versus active behaviors.

Perception of stochastically undersampled sound waveforms: A model of auditory deafferentation

Frontiers in Neuroscience, 2013
Auditory deafferentation, or permanent loss of auditory nerve afferent terminals, occurs after noise overexposure and aging and may accompany many forms of hearing loss. It could cause significant auditory impairment but is undetected by regular clinical
