Neuromodulatory silencing of nerve terminals

Kavli Affiliate: Timothy A. Ryan | Authors: Daniel Charles Cook and Timothy Aidan Ryan | Summary: Abstract Control of neurotransmission efficacy is central to theories of how the brain computes and stores information. Neuromodulators are critical in this problem as they locally influence synaptic strength and can operate on a wide range of time scales. […]

Cortico-cortical and hippocampo-cortical co-rippling are facilitated by thalamo-cortical spindles and upstates, but not by thalamic ripples

Kavli Affiliate: Eric Halgren | Authors: Charles W Dickey, Ilya A Verzhbinsky, Sophie Kajfez, Burke Q Rosen, Sandipan Pati and Eric Halgren | Summary: Abstract The co-occurrence of brief ~90 Hz oscillations (co-ripples) may be important in integrating information across the cortex and hippocampus, essential for sleep consolidation, and cognition in general. However, how such […]
