Contextual and pure time coding for self and other in the hippocampus

Autor: David B. Omer, Liora Las, Nachum Ulanovsky

Publikováno v: Nature Neuroscience. 26:285-294

Navigation and episodic memory depend critically on representing temporal sequences. Hippocampal 'time cells' form temporal sequences, but it is unknown whether they represent context-dependent experience or time per se. Here we report on time cells

In this issue of Cell, Zhang and Yartsev, 2019 and Kingsbury et al. (2019) provide insight into the emergence of synchronized neuronal activity between prefrontal cortices of two brains that share the same social context via electrophysiology recordi

Publikováno v: NeuroImage. 183

Critical dynamics are thought to play an important role in neuronal information-processing: near critical networks exhibit neuronal avalanches, cascades of spatiotemporal activity that are scale-free, and are considered to enhance information capacit

Optical imaging based on intrinsic signals has provided a new level of understanding of the principles underlying cortical development, organization, and function, providing a spatial resolution of up to 20 µm for mapping cortical columns in vivo. T

Neural computations underlying sensory perception, cognition, and motor control are performed by populations of neurons at different anatomical and temporal scales. Few techniques are currently available for exploring dynamics of local and large rang
