Trio preserves motor synapses and prolongs motor ability during aging

Evelyne Ruchti, Brian Donal McCabe, Soumya Banerjee, Greta Limoni, Samuel William Vernon, Wei Jiao

The decline of motor ability is a hallmark feature of aging and is accompanied by degeneration of motor synaptic terminals. Consistent with this, Drosophila motor synapses undergo characteristic age -dependent structural fragmentation co -incident with dim ...

Investigating the Serotonergic Modulation of Orientation Tuning of Neurons in Primary Visual Cortex of Anesthetized Mice

Parviz Ghaderi

Introduction: Sensory processing is profoundly regulated by brain neuromodulatory systems. One of the main neuromodulators is serotonin which influences higher cognitive functions, such as different aspects of perceptual processing. Accordingly, malfunctio ...

Drosophila SPG12 ortholog, reticulon-like 1, governs presynaptic ER organization and Ca2+ dynamics

Rebecca Carolyn Smith

Neuronal endoplasmic reticulum (ER) appears continuous throughout the cell. Its shape and continuity are influenced by ER-shaping proteins, mutations in which can cause distal axon degeneration in Hereditary Spastic Paraplegia (HSP). We therefore asked how ...

GABAergic-like dopamine synapses in the brain

Maria Reva

Dopamine synapses play a crucial role in volitional movement and reward-related behaviors, while dysfunction of dopamine synapses causes various psychiatric and neurological disorders. Despite this significance, the true biological nature of dopamine synap ...

Accompagner la fabrique de l'espace public inclusif ; Deuxième campagne d'observation sur trois espaces publics genevois

Marc Antoine Messer, Kamil Hajji, Diego Alejandro Marcelo Mermoud, Yannick Pitton

Lors de la première campagne d’observation réalisée en 2020 sur les mêmes terrains genevois, nous concluions sur la nécessité de comprendre l’inclusivité de l’espace public sous le prisme de l’aménité de l’espace. Dans cette appréhension les usagers vienne ...

Sensing serotonin secreted from human serotonergic neurons using aptamer-modified nanopipettes

Nako Nakatsuka, Dmitry Momotenko

The serotonergic system in the human brain modulates several physiological processes, and altered serotonergic neurotransmission has been implicated in the neuropathology of several psychiatric disorders. The study of serotonergic neurotransmission in psyc ...

Aptamer Conformational Change Enables Serotonin Biosensing with Nanopipettes

Nako Nakatsuka, Dmitry Momotenko, Dominic Eggemann, Csaba Forro

We report artificial nanopores in the form of quartz nanopipettes with ca. 10 nm orifices functionalized with molecular recognition elements termed aptamers that reversibly recognize serotonin with high specificity and selectivity. Nanoscale confinement of ...

Combining robotics with enhanced serotonin-driven cortical plasticity improves post-stroke motor recovery

Silvestro Micera, Stefano Lai, Maria Pasquini, Sara Conti, Marco Mainardi

Despite recent progresses in robotic rehabilitation technologies, their efficacy for post-stroke motor recovery is still limited. Such limitations might stem from the insufficient enhancement of plasticity mechanisms, crucial for functional recovery. Here, ...

Implantable aptamer–field-effect transistor neuroprobes for in vivo neurotransmitter monitoring

Nako Nakatsuka

While tools for monitoring in vivo electrophysiology have been extensively developed, neurochemical recording technologies remain limited. Nevertheless, chemical communication via neurotransmitters plays central roles in brain information processing. We de ...

Computationally-guided tuning of ligand sensitivity in a GPCR-based sensor

Patrick Daniel Barth, Dániel Kéri

Genetically-encoded fluorescent sensors for neuromodulators are increasingly used molecular tools in neuroscience. However, these protein-based biosensors are often limited by the sensitivity of the protein scaffold towards endogenous ligands. Here, we exp ...
