Parvalbumin-Expressing GABAergic Neurons in Mouse Barrel Cortex Contribute to Gating a Goal-Directed Sensorimotor Transformation

Carl Petersen, Berat Semihcan Sermet, Shankar Sachidhanandam

Sensory processing in neocortex is primarily driven by glutamatergic excitation, which is counterbalanced by GABAergic inhibition, mediated by a diversity of largely local inhibitory interneurons. Here, we trained mice to lick a reward spout in response to ...

Implication of individual differences in glucocorticoid responsiveness to stress in the development of psychopathology-like behaviour and underlying neurobiology

Sophie Elizabeth Walker

The period around puberty is a critical window in development. It is a time of neuroendocrine and neuroanatomical lability, rendering individuals highly sensitive to stress. Indeed, early adversity increases risk for psychopathology. The mechanisms via whi ...

Identification of the Link Between the Hypothalamo-Pituitary Axis and the Testicular Orphan Nuclear Receptor NR0B2 in Adult Male Mice

Kristina Schoonjans

The small heterodimer partner (SHP, nuclear receptor subfamily 0, group B, member 2; NR0B2) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We previously showed that NR0B2 controls testicular f ...

Understanding and Engineering Thermostability in DNA Ligase from Thermococcus sp 1519

Matteo Dal Peraro, Hasan Pezeshgi Modarres

The physical chemical principles underlying,enzymatic thermostability are keys to understand the way evolution has shaped proteins,to adapt to a broad range of temperatures. Understanding the molecular determinants at the basis of protein thermostability i ...

Medial Forebrain Bundle Deep Brain Stimulation has Symptom-specific Anti-depressant Effects in Rats and as Opposed to Ventromedial Prefrontal Cortex Stimulation Interacts With the Reward System

Background: In recent years, deep brain stimulation (DBS) has emerged as a promising treatment option for patients suffering from treatment-resistant depression (TRD). Several stimulation targets have successfully been tested in clinical settings, includin ...

Hypothalamic S1P/S1PR1 axis controls energy homeostasis

Dongryeol Ryu

Sphingosine 1-phosphate receptor 1 (S1PR1) is a G-protein-coupled receptor for sphingosine-1-phosphate (S1P) that has a role in many physiological and pathophysiological processes. Here we show that the S1P/S1PR1 signalling pathway in hypothalamic neurons ...

Direct mapping of 19F in 19FDG-6P in brain tissue at subcellular resolution using soft X-ray fluorescence

Rolf Gruetter, Carole Poitry-Yamate

Low energy x-ray fluorescence (LEXRF) detection was optimized for imaging cerebral glucose metabolism by mapping the fluorine LEXRF signal of 19 F in 19 FDG, trapped as intracellular 19 F-deoxyglucose-6-phosphate ( 19 FDG-6P) at 1μm spatial resolution from ...

Impact of environmental estrogens on fish considering the diversity of estrogen signaling

Research on endocrine disruption in fish has been dominated by studies on estrogen-active compounds which act as mimics of the natural estrogen, 17 beta-estradiol (E2), and generally exert their biological actions by binding to and activation of estrogen r ...

Stress during puberty boosts metabolic activation associated with fear-extinction learning in hippocampus, basal amygdala and cingulate cortex

Maria del Carmen Sandi Perez

Adolescence is characterized by major developmental changes that may render the individual vulnerable to stress and the development of psychopathologies in a sex-specific manner. Earlier we reported lower anxiety-like behavior and higher risk-taking and no ...

Effect of manganese chloride on the neurochemical profile of the rat hypothalamus

Rolf Gruetter, Cristina Ramona Cudalbu Moldovan, Hongxia Lei, Nathalie Just

Manganese (Mn 2+)-enhanced magnetic resonance imaging studies of the neuronal pathways of the hypothalamus showed that information about the regulation of food intake and energy balance circulate through specific hypothalamic nuclei. The dehydration-induce ...

Detection of neuronal activity and metabolism in a model of dehydration-induced anorexia in rats at 14.1T using manganese-enhanced MRI and 1H MRS

Rolf Gruetter, Nathalie Just

In this study, hypothalamic activation was performed by dehydration-induced anorexia (DIA) and overnight food suppression (OFS) in female rats. The assessment of the hypothalamic response to these challenges by manganese-enhanced MRI showed increased neuro ...
