Neuronal activity in the brain gives rise to transmembrane currents that can be measured in
the extracellular medium. Although the major contributor of the extracellular signal is the …

… (c) Simulated impact of in vivo spatiotemporal V e -fluctuations on the membrane potential
of a cell. Extracellular activity recorded in the behaving rat from CA1 during sharp wave …

… c–f, Quantification of neuron yield across 9 brain structures (n = 15 recordings from 13
mice)… For each structure, we computed: the total number of putative single neurons (c); the …

… Slices were incubated at 37 C for 30–60 min and then left at 25 C until recording. Cells
were visualized by infrared differential interference contrast videomicroscopy using a VX55 …

The neocortex is disproportionately expanded in human compared with mouse 1 , 2 , both
in its total volume relative to subcortical structures and in the proportion occupied by …

Nutrition is a modifiable factor affecting the quality of life and independence of older people.
The physiological, psychological and social changes during aging affect their dietary choices…

Precisely how rhythms support neuronal communication remains obscure. We investigated
interregional coordination of gamma oscillations using high-density electrophysiological …
