theta rhythms การใช้

• The function of the hippocampal theta rhythm is not clearly understood.
• The synchronous theta rhythm ranges from 4 to 7 Hz.
• The nucleus incertus itself presents theta oscillations coupled to the hippocampal theta rhythm.
• Hippocampal theta rhythms in other species differ in some respects from those in rats.
• Theta rhythms are found in the hippocampus and GABAergic synaptic inhibition helps to modulate them.
• From rodent studies it has been proposed that the trisynaptic circuit generates the hippocampal theta rhythm.
• Another theory links the theta rhythm to mechanisms of learning and memory ( Hasselmo, 2005 ).
• Cortical theta rhythms observed in human scalp EEG are a different phenomenon, with no clear relationship to the hippocampus.
• Thus the rat hippocampal EEG oscillation should not, strictly speaking, have been called a " theta rhythm ".
• Maxwell Cade co-developed the " Mind Mirror ", a portable theta rhythms from each brain hemisphere simultaneously.
• The EEG reveals information about a theta rhythm signature that occurs when people with the Ability attempt to control others.
• Tonic REM is characterized by theta rhythms in the brain; phasic REM is characterized by PGO waves and actual  rapid eye movements.
• Another interesting study of inhibitory postsynaptic potentials looks at neuronal theta rhythm oscillations that can be used to represent electrophysiological phenomena and various behaviors.
• In humans, hippocampal theta rhythm has been observed and linked to " memory formation " and " navigation ".
• A significant part of Prof . Vinogradova s scientific career was devoted to the analysis of the role of theta rhythm in hippocampal function.
• The stimulation of the nucleus incertus activates the hippocampal theta rhythm and either its lesion or inhibition suppress the theta oscillation induced by brainstem stimulation.
• Theta rhythm with its low frequency of around 6 7 Hz in a steady oscillation has been observed in rats that are motionless but alert.
• A major research problem has been to discover the " pacemaker " for the theta rhythm, that is, the mechanism that determines the oscillation frequency.
• In general, it is not safe to assume that observations of " theta " in the human EEG have any relationship to the " hippocampal theta rhythm ".
• Specifically, cells in this area are modulated by local theta rhythm, and display theta-frequency membrane potential oscillations ( Glasgow & Chapman, 2007; Taube, 1995 ).
