TL;DR: Whether the sequence of events during theta formation supports the classic view of septal drive or the challenging theory of hippocampal pacing of theta is uncovered by analyzing the temporal relationship of activity between the PV/HCN-containing medial sePTal neurons and hippocampal local field potential.

TL;DR: Findings show that medial septal cholinergic activation can both enhance theta rhythm and suppress peri-theta frequency bands, allowing theta oscillations to dominate.

TL;DR: A form of subcortical control of cortical information processing whereby strong, spatiotemporally precise excitatory input from midbrain serotonergic neurons produces a robust activation of hippocampal interneurons is described.

TL;DR: In this paper, the authors used in vivo juxtacellular recording and filling in the medial septum followed by immunocytochemical identification of the recorded cells containing parvalbumin to determine their firing pattern, phase relationship with hippocampal theta, morphology, and to reveal their involvement in the generation of hippocampal hippocampus theta activity.

TL;DR: These data provide the first evidence that the ventral medial prefrontal cortex influences the activity of large numbers of raphe 5-HT neurones by targeting a local network of GABA neurones.
