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 ...
Cell Press2024Fear learning induces synaptic potentiation between engram neurons in the rat lateral amygdala
Henry Markram, Rodrigo de Campos Perin
The lateral amygdala (LA) encodes fear memories by potentiating sensory inputs associated with threats and, in the process, recruits 10-30% of its neurons per fear memory engram. However, how the local network within the LA processes this information and w ...
Nature Portfolio2024A maturational shift in the frontal cortex synaptic transcriptional landscape underlies schizophrenia-relevant behavioural traits: A congenital rat model
Disruption of brain development early in life may underlie the neurobiology behind schizophre-nia. We have reported more immature synaptic spines in the frontal cortex (FC) of adult Roman High-Avoidance (RHA-I) rats, a behavioural model displaying schizoph ...
2023Principles of Network Plasticity in Neocortical Microcircuits
Synaptic plasticity underlies our ability to learn and adapt to the constantly changing environment. The phenomenon of synapses changing their efficacy in an activity-dependent manner is often studied in small groups of neurons in vitro or indirectly throu ...
EPFL2023Long-term plasticity induces sparse and specific synaptic changes in a biophysically detailed cortical model
Eilif Benjamin Muller, Michael Reimann, James Gonzalo King, Marwan Muhammad Ahmed Abdellah, Pramod Shivaji Kumbhar, András Ecker, Sirio Bolaños Puchet, James Bryden Isbister, Daniela Egas Santander, Jorge Blanco Alonso, Giuseppe Chindemi, Ioannis Magkanaris
Synaptic plasticity underlies the brain’s ability to learn and adapt. This process is often studied in small groups of neurons in vitro or indirectly through its effects on behavior in vivo. Due to the limitations of available experimental techniques, inve ...
2023Ferroelectric Junctionless Double-Gate Silicon-On-Insulator FET as a Tripartite Synapse
Mihai Adrian Ionescu, Igor Stolichnov, Ali Saeidi, Sadegh Kamaei Bahmaei, Matteo Cavalieri, Carlotta Gastaldi
In this work, we report the concept and experimentally demonstrate the first tunable ferroelectric (Fe) junctionless (JL) transistor (Fe-JLFET), capable of emulating the functionality of biological tri-partite synapses, which is an artificial three-termina ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Drosophila SPG12 ortholog, reticulon-like 1, governs presynaptic ER organization and Ca2+ dynamics
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 ...
New York2023Mechanisms Underlying the Recruitment of Inhibitory Interneurons in Fictive Swimming in Developing Xenopus laevis Tadpoles
Developing spinal circuits generate patterned motor outputs while many neurons with high membrane resistances are still maturing. In the spinal cord of hatchling frog tadpoles of unknown sex, we found that the firing reliability in swimming of inhibitory i ...
SOC NEUROSCIENCE2023Neuromodulatory organization in the developing rat somatosensory cortex
Henry Markram, Srikanth Ramaswamy, Armando Romani, Cristina Colangelo, Alberto Antonietti, Joni Henrikki Herttuainen
The vast majority of cortical synapses are found in the neuropil which is implicated in multiple and diverse functions underlying brain computation. Unraveling the organizing principles of the cortical neuropil requires an intricate characterization of syn ...
2022Mechanistic Understanding of Neurobehavioral Effects of Insecticides on the Larvae of Zebrafish (Danio rerio)
Due to conservation of neuronal functioning across phyla, molecular targets of insecticides are similar in insects and vertebrates. Insecticides thus pose a risk to aquatic vertebrates,such as fish, and potentially cause neurotoxic effects. Although these ...
