Based on recent molecular genetics, as well as functional and quantitative anatomical
studies, the basal forebrain (BF) cholinergic projections, once viewed as a diffuse system, are …

The medial septum/diagonal band of Broca complex (MSDB) is a key structure that modulates
hippocampal rhythmogenesis. Cholinergic neurons of the MSDB play a central role in …

The neurotransmitter acetylcholine, derived from the medial septum/diagonal band of Broca
complex, has been accorded an important role in hippocampal learning and memory …

This article provides a review of the effects of activation of muscarinic and nicotinic receptors
on the physiological properties of circuits in the hippocampal formation. Previous articles …

The signal regulatory protein-β1 (SIRPβ1) is a DAP12-associated transmembrane receptor
expressed in a subset of hematopoietic cells. Recently, it was shown that peritoneal …

Neurophysiological recordings in behaving rodents demonstrate neuronal response properties
that may code space and time for episodic memory and goal-directed behaviour. Here, …

Neuronal representations of spatial location and movement speed in the medial entorhinal
cortex during the ‘active’ theta state of the brain are important for memory-guided navigation …

Animals must perform spatial navigation for a range of different behaviors, including selection
of trajectories toward goal locations and foraging for food sources. To serve this function, a …

The firing rate of speed cells, a dedicated subpopulation of neurons in the medial entorhinal
cortex (MEC), is correlated with running speed. This correlation has been interpreted as a …

Cholinergic projection neurons in the medial septum and diagonal band of Broca are the
major source of cholinergic modulation of hippocampal circuit functions that support neural …
