Alzheimer's disease (AD) is a devastating disorder that leads to memory loss and dementia. Neurodegeneration of cholinergic neurons in the septum and other basal forebrain areas is evident in early stages of AD. Glutamatergic neurons are also affected early in AD. In these stages, amyloid-β-peptide (Aβ) plaques are present in the hippocampus and other… (More)
Resting-state magnetic resonance imaging (rsMRI) is thought to reflect ongoing spontaneous brain activity. However, the precise neurophysiological basis of rsMRI signal remains elusive. Converging evidence supports the notion that local field potential (LFP) signal in the high-frequency range correlates with fMRI response evoked by a task (e.g., visual… (More)
Septal inputs critically modulate hippocampal function. However, the role of Medial Septal/Diagonal Band (MS/ DB) neuronal populations in hippocampal theta rhythm generation is still under debate. MS/DB GABAergic neurons selectively innervate inhibitory hippocampal interneurons and through this action exert a powerful control on hippocampal excitability. To… (More)
