DOI: 10.1016/j.neuroscience.2020.01.007
Abstract: Ethanol is one of the most widely used drugs - with many psychoactive effects, including anxiolysis. The deleterious effects on brain function and general health of chronic and high-level ethanol use are well-studied. However, the… read more here.

DOI: 10.1126/sciadv.aav8192
Abstract: Hippocampal theta cycles provide a means to maintain and segregate different goal representations during human wayfinding. Humans are adept in simultaneously following multiple goals, but the neural mechanisms for maintaining specific goals and distinguishing them… read more here.

DOI: 10.3389/fnbeh.2022.811278
Abstract: The hippocampal formation is one of the brain systems in which the functional roles of coordinated oscillations in information representation and communication are better studied. Within this circuit, neuronal oscillations are conceived as a mechanism… read more here.

DOI: 10.3390/biomedicines10040745
Abstract: Cholinergic regulation of hippocampal theta rhythm has been proposed as one of the central mechanisms underlying hippocampal functions including spatial memory encoding. However, cholinergic transmission has been traditionally associated with atropine-sensitive type II hippocampal theta… read more here.

Selective Modulation of Hippocampal Theta Oscillations in Response to Morphine versus Natural Reward
Sign Up to like & getrecommendations! Published in 2023 at "Brain Sciences"
DOI: 10.3390/brainsci13020322
Abstract: Despite the overlapping neural circuits underlying natural and drug rewards, several studies have suggested different behavioral and neurochemical mechanisms in response to drug vs. natural rewards. The strong link between hippocampal theta oscillations (4–12 Hz)… read more here.
