[HTML][HTML] The microstructure of REM sleep: Why phasic and tonic?

P Simor, G van der Wijk, L Nobili, P Peigneux - Sleep medicine reviews, 2020 - Elsevier
Rapid eye movement (REM) sleep is a peculiar neural state that occupies 20–25% of
nighttime sleep in healthy human adults and seems to play critical roles in a variety of …

[HTML][HTML] Theta oscillations in the hippocampus

G Buzsáki - Neuron, 2002 - cell.com
Theta oscillations represent the" on-line" state of the hippocampus. The extracellular
currents underlying theta waves are generated mainly by the entorhinal input, CA3 …

The default-mode, ego-functions and free-energy: a neurobiological account of Freudian ideas

RL Carhart-Harris, KJ Friston - Brain, 2010 - academic.oup.com
This article explores the notion that Freudian constructs may have neurobiological
substrates. Specifically, we propose that Freud's descriptions of the primary and secondary …

Atlas of the normal intracranial electroencephalogram: neurophysiological awake activity in different cortical areas

B Frauscher, N Von Ellenrieder, R Zelmann… - Brain, 2018 - academic.oup.com
In contrast to scalp EEG, our knowledge of the normal physiological intracranial EEG activity
is scarce. This multicentre study provides an atlas of normal intracranial EEG of the human …

Human hippocampal theta oscillations and the formation of episodic memories

BC Lega, J Jacobs, M Kahana - Hippocampus, 2012 - Wiley Online Library
The importance of the hippocampal theta oscillation (4–8 Hz) to memory formation has been
well‐established through studies in animals, prompting researchers to propose …

The role of REM sleep theta activity in emotional memory

IC Hutchison, S Rathore - Frontiers in psychology, 2015 - frontiersin.org
While non-REM (NREM) sleep has been strongly implicated in the reactivation and
consolidation of memory traces, the role of rapid-eye movement (REM) sleep remains …

Hippocampal theta oscillations are slower in humans than in rodents: implications for models of spatial navigation and memory

J Jacobs - … Transactions of the Royal Society B …, 2014 - royalsocietypublishing.org
The theta oscillation is a neuroscience enigma. When a rat runs through an environment,
large-amplitude theta oscillations (4–10 Hz) reliably appear in the hippocampus's electrical …

Theta returns

MJ Kahana, D Seelig, JR Madsen - Current opinion in neurobiology, 2001 - Elsevier
