Locus coeruleus alterations in dementia with Lewy bodies: A systematic review. [PDF]

open access: yesAlzheimers Dement (N Y)
Abstract INTRODUCTION The locus coeruleus (LC) is a small nucleus located deep within the brainstem, serving as the brain's main source of noradrenergic neurons. Through its extensive projections, it plays a critical role in regulating cognitive processes and arousal.

Gulf War Syndrome: A role for organophosphate induced plasticity of locus coeruleus neurons [PDF]

open access: yes, 2011
Gulf War syndrome is a chronic multi-symptom illness that has affected about a quarter of the deployed veterans of the 1991 Gulf War. Exposure to prolonged low-level organophosphate insecticides and other toxic chemicals is now thought to be responsible.

Altered brainstem responses to modafinil in schizophrenia: implications for adjunctive treatment of cognition. [PDF]

open access: yes, 2018
Candidate pro-cognitive drugs for schizophrenia targeting several neurochemical systems have consistently failed to demonstrate robust efficacy. It remains untested whether concurrent antipsychotic medications exert pharmacodynamic interactions that ...

Lack of kinase-independent activity of PI3Kγ in locus coeruleus induces ADHD symptoms through increased CREB signaling. [PDF]

open access: yes, 2015
Although PI3Kγ has been extensively investigated in inflammatory and cardiovascular diseases, the exploration of its functions in the brain is just at dawning.

Locus Coeruleus in Non-Mammalian Vertebrates

open access: yesBrain Sciences, 2022
The locus coeruleus (LC) is a vertebrate-specific nucleus and the primary source of norepinephrine (NE) in the brain. This nucleus has conserved properties across species: highly homogeneous cell types, a small number of cells but extensive axonal ...

Visual and Electrosensory Circuits of the Diencephalon in Mormyrids [PDF]

open access: yes, 1990
Mormyrids are one of two groups of teleost fishes known to have evolved electroreception, and the concomitant neuroanatomical changes have confounded the interpretation of many of their brain areas in a comparative context, e.g., the diencephalon, where ...

Prepontine non-giant neurons drive flexible escape behavior in zebrafish [PDF]

open access: yes, 2019
Many species execute ballistic escape reactions to avoid imminent danger. Despite fast reaction times, responses are often highly regulated, reflecting a trade-off between costly motor actions and perceived threat level.

State-Dependent Subnetworks of Parvalbumin-Expressing Interneurons in Neocortex. [PDF]

open access: yes, 2019
Brain state determines patterns of spiking output that underlie behavior. In neocortex, brain state is reflected in the spontaneous activity of the network, which is regulated in part by neuromodulatory input from the brain stem and by local inhibition ...

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]

open access: yes, 2013
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Quantifying the contrast of the human locus coeruleus in vivo at 7 Tesla MRI.

open access: yesPLoS ONE, 2019
The locus coeruleus is a small brainstem nucleus which contains neuromelanin cells and is involved in a number of cognitive functions such as attention, arousal and stress, as well as several neurological and psychiatric disorders.
