Theta-associated high-frequency oscillations (110–160 Hz) in the hippocampus and neocortex

ABL Tort, R Scheffer-Teixeira, BC Souza… - Progress in …, 2013 - Elsevier
We review recent evidence for a novel type of fast cortical oscillatory activity that occurs
circumscribed between 110 and 160Hz, which we refer to as high-frequency oscillations (HFOs). …

On high-frequency field oscillations (> 100 Hz) and the spectral leakage of spiking activity

R Scheffer-Teixeira, H Belchior, RN Leao… - Journal of …, 2013 - Soc Neuroscience
Recent reports converge to the idea that high-frequency oscillations in local field potentials (LFPs)
represent multiunit activity. In particular, the amplitude of LFP activity above 100 Hz—…

Theta phase modulates multiple layer-specific oscillations in the CA1 region

R Scheffer-Teixeira, H Belchior, FV Caixeta… - Cerebral …, 2012 - academic.oup.com
It was recently proposed that fast gamma oscillations (60–150 Hz) convey spatial information
from the medial entorhinal cortex (EC) to the CA1 region of the hippocampus. However, …

On cross-frequency phase-phase coupling between theta and gamma oscillations in the hippocampus

R Scheffer-Teixeira, ABL Tort - elife, 2016 - elifesciences.org
… Using computer simulations and recordings from the rat hippocampus, Scheffer-Teixeira and
… Using stringent control analyses, Scheffer-Teixeira and Tort find no evidence for prominent …

[HTML][HTML] Ketamine alters oscillatory coupling in the hippocampus

FV Caixeta, AM Cornélio, R Scheffer-Teixeira… - Scientific reports, 2013 - nature.com
Recent studies show that higher order oscillatory interactions such as cross-frequency coupling
are important for brain functions that are impaired in schizophrenia, including perception…

[HTML][HTML] Dopamine modulates delta-gamma phase-amplitude coupling in the prefrontal cortex of behaving rats

…, R Scheffer-Teixeira, ABL Tort, R Etchenique… - Frontiers in neural …, 2017 - frontiersin.org
Dopamine release and phase-amplitude cross-frequency coupling (CFC) have independently
been implicated in prefrontal cortex (PFC) functioning. To causally investigate whether …

Stress response recruits the hippocampal endocannabinoid system for the modulation of fear memory

…, DS Engelke, F Diehl, R Scheffer-Teixeira… - Learning & …, 2010 - learnmem.cshlp.org
The modulation of memory processes is one of the several functions of the endocannabinoid
system (ECS) in the brain, with CB1 receptors highly expressed in areas such as the dorsal …

Unveiling fast field oscillations through comodulation

R Scheffer-Teixeira, ABL Tort - ENeuro, 2017 - eneuro.org
Phase-amplitude coupling analysis shows that theta phase modulates oscillatory activity not
only within the traditional gamma band (30–100 Hz) but also at faster frequencies, called …

Neurophysiological effects in cortico-basal ganglia-thalamic circuits of antidyskinetic treatment with 5-HT1A receptor biased agonists

I Brys, P Halje, R Scheffer-Teixeira, M Varney… - Experimental …, 2018 - Elsevier
Recently, the biased and highly selective 5-HT 1A agonists, NLX-112, F13714 and F15599,
have been shown to alleviate dyskinesia in rodent and primate models of Parkinson's …

Lack of evidence for cross-frequency phase-phase coupling between theta and gamma oscillations in the hippocampus

R Scheffer-Teixeira, ABL Tort - bioRxiv, 2016 - biorxiv.org
Phase-amplitude coupling between theta and multiple gamma sub-bands hallmarks
hippocampal activity and is believed to take part in information routing. More recently, theta and …
