Limiting habenular hyperactivity ameliorates maternal separation-driven depressive-like symptoms

open access: yesNature Communications, 2017
Early-life stress primes depression in adulthood. This study shows that early maternal separation leads to lateral habenula (LHb) hyperactivity and causes depressive-like phenotypes, the latter being reversible when LHb hyperactivity is reduced ...

Somato-Dendritic Regulation of Raphe Serotonin Neurons; A Key to Antidepressant Action

open access: yesFrontiers in Neuroscience, 2018
Several lines of evidence implicate serotonin (5-hydroxytryptamine, 5-HT)in regulating personality traits and mood control. Serotonergic neurons are classically thought to be tonic regular-firing, “clock-like” neurons.

Encoding many-valued logic in {\lambda}-calculus

open access: yes, 2020
We extend the well-known Church encoding of two-valued Boolean Logic in $\lambda$-calculus to encodings of $n$-valued propositional logic (for $3\leq n\leq 5$) in well-chosen infinitary extensions in $\lambda$-calculus.

Evidence for suboxic nitrification in recent marine sediments [PDF]

open access: yes, 2002
The classical scheme of biogeochemical zones (BGZ) is known to be an oversimplification of the microbial processes that occur in organic-rich marine sediments.

Refining the Role of 5-HT in Postnatal Development of Brain Circuits

open access: yesFrontiers in Cellular Neuroscience, 2017
Changing serotonin (5-hydroxytryptamine, 5-HT) brain levels during critical periods in development has long-lasting effects on brain function, particularly on later anxiety/depression-related behaviors in adulthood.

Dorsal raphe serotonin neurotransmission is required for the expression of nursing behavior and for pup survival

open access: yesScientific Reports, 2021
Proper maternal care is an essential factor of reproductive success in mammals, involving a repertoire of behaviors oriented toward the feeding and care of the offspring.

mGluR-LTD at Excitatory and Inhibitory Synapses in the Lateral Habenula Tunes Neuronal Output

open access: yesCell Reports, 2016

Conformational state-dependent regulation of GABAA receptor diffusion and subsynaptic domains

open access: yesiScience, 2022
Summary: The efficacy of GABAergic synapses relies on the number of postsynaptic GABAA receptors (GABAARs), which is regulated by a diffusion capture mechanism.

Differential enhancement of ERK, PKA and Ca2+ signaling in direct and indirect striatal neurons of Parkinsonian mice

open access: yesNeurobiology of Disease, 2019
Parkinson's disease (PD) is characterized by severe locomotor deficits due to the disappearance of dopamine (DA) from the dorsal striatum. The development of PD symptoms and treatment-related complications such as dyskinesia have been proposed to result ...
