Characterization Of Continuously Oscillating Neurons (Cons) Of The Medial Septum Of Rats, Nadia Noel Carreon

Theses and Dissertations - UTB/UTPA

Theta oscillation is the largest extracellular synchronous signal that can be recorded from the mammalian brain. It is known to influence information retention in the hippocampus, which plays a key role in declarative memory, recognition memory, working memory, and spatial memory. The theta oscillation field frequency is between 3 and 12 Hz and is present during exploratory behavior and sleep in rodents. Theta rhythm in the hippocampus is postulated to be produced by the rhythmical activity of pacemaking cells in the medial septumvertical limb of the diagonal band of Broca (MS-vDBB). Previous work in our laboratory demonstrated the existence of …
