Specific basal forebrain–cortical cholinergic circuits coordinate cognitive operations

…, ME Hasselmo, H Dannenberg… - Journal of …, 2018 - Soc Neuroscience
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 …

Synergy of direct and indirect cholinergic septo-hippocampal pathways coordinates firing in hippocampal networks

H Dannenberg, M Pabst, O Braganza… - Journal of …, 2015 - Soc Neuroscience
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 …

[PDF][PDF] Astrocyte intermediaries of septal cholinergic modulation in the hippocampus

M Pabst, O Braganza, H Dannenberg, W Hu… - Neuron, 2016 - cell.com
The neurotransmitter acetylcholine, derived from the medial septum/diagonal band of Broca
complex, has been accorded an important role in hippocampal learning and memory …

[HTML][HTML] Modulation of hippocampal circuits by muscarinic and nicotinic receptors

H Dannenberg, K Young, M Hasselmo - Frontiers in neural circuits, 2017 - frontiersin.org
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 …

Signal regulatory protein-β1: a microglial modulator of phagocytosis in Alzheimer's disease

S Gaikwad, S Larionov, Y Wang, H Dannenberg… - The American journal of …, 2009 - Elsevier
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 coding of space and time in the hippocampus, entorhinal cortex, and retrosplenial cortex

…, JC Robinson, H Dannenberg… - Brain and …, 2020 - journals.sagepub.com
Neurophysiological recordings in behaving rodents demonstrate neuronal response properties
that may code space and time for episodic memory and goal-directed behaviour. Here, …

Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex

H Dannenberg, H Lazaro, P Nambiar, A Hoyland… - Elife, 2020 - elifesciences.org
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 …

Neural mechanisms of navigation involving interactions of cortical and subcortical structures

JR Hinman, H Dannenberg… - Journal of …, 2018 - journals.physiology.org
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 speed code of entorhinal speed cells differs across behaviorally relevant time scales and does not depend on medial septum inputs

H Dannenberg, C Kelley, A Hoyland… - Journal of …, 2019 - Soc Neuroscience
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 …

[HTML][HTML] Temporal dynamics of cholinergic activity in the septo-hippocampal system

…, P Nambiar, ME Hasselmo, H Dannenberg - Frontiers in Neural …, 2022 - frontiersin.org
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 …
