Layer-Dependent Short-Term Synaptic Plasticity Between Excitatory Neurons in the C2 Barrel Column of Mouse Primary Somatosensory Cortex

Carl Petersen, Sandrine Lefort

Neurons process information through spatiotemporal integration of synaptic input. Synaptic transmission between any given pair of neurons is typically a dynamic process with presynaptic action potentials (APs) evoking depressing or facilitating postsynapti ...

Functional and structural properties of strong inhibitory synapses in a binaural auditory circuit

Enida Gjoni

Neuronal circuits are defined in their function and computational outcome by the synaptic interplay of Excitation and Inhibition (E/I). One step further in understanding the role of these opposite interactors in neuronal computations consists in determinin ...

Synaptotagmin2 (Syt2) Drives Fast Release Redundantly with Syt1 at the Output Synapses of Parvalbumin-Expressing Inhibitory Neurons

Ralf Schneggenburger, Olexiy Kochubey, Enida Gjoni, Brice Antoine Alexandre Bouhours

Parvalbumin-expressing inhibitory neurons in the mammalian CNS are specialized for fast transmitter release at their output synapses. However, the Ca2+ sensor(s) used by identified inhibitory synapses, including the output synapses of parvalbumin-expressin ...

Neuronal Depolarization Drives Increased Dopamine Synaptic Vesicle Loading via VGLUT

Brian Donal McCabe

The ability of presynaptic dopamine terminals to tune neurotransmitter release to meet the demands of neuronal activity is critical to neurotransmission. Although vesicle content has been assumed to be static, in vitro data increasingly suggest that cell a ...

Genetic dissection of the role of BMP signaling for the development of the auditory brainstem nuclei and the large calyx of Held synapse

Elin Kristina Kronander

Synapses are key elements for communication within the complex network of neurons that make up our brain. Interestingly, synaptic connections can differ greatly in form and function, depending on the specific circuit into which they are embedded. In this P ...

Neuromodulated-Spike-Timing-Dependent Pasticity, and Theory of Three-Factor Learning Rules

Wulfram Gerstner, Nicolas Frémaux

Classical Hebbian learning puts the emphasis on joint pre- and postsynaptic activity, but neglects the potential role of neuromodulators. Since neuromodulators convey information about novelty or reward, the influence of neuromodulators on synaptic plastic ...

Proteolytic processing of the synaptic cell adhesion molecule neurexin-3beta and the neurobiological functions of the resulting cleavage products

Magda Maria Palczynska

Neurexins are key synaptic cell adhesion molecules involved in synapse specification and maturation. They couple synaptic activity and cell adhesion to regulate activity-dependent synapse development. Recently, neurexin processing by alpha- and gamma- secr ...

An Exclusion Zone for Ca2+ Channels around Docked Vesicles Explains Release Control by Multiple Channels at a CNS Synapse

Henry Markram, Felix Schürmann, Ralf Schneggenburger, Daniel Keller, Olexiy Kochubey, Yunyun Han

The spatial arrangement of Ca2+ channels and vesicles remains unknown for most CNS synapses, despite of the crucial importance of this geometrical parameter for the Ca2+ control of transmitter release. At a large model synapse, the calyx of Held, transmitt ...

Delayed and Temporally Imprecise Neurotransmission in Reorganizing Cortical Microcircuits

Graham Knott, Anne Alison Jorstad, Yan Liu

Synaptic neurotransmission is modified at cortical connections throughout life. Varying the amplitude of the postsynaptic response is one mechanism that generates flexible signaling in neural circuits. The timing of the synaptic response may also play a ro ...

RIM1 and RIM2 redundantly determine Ca2+ channel density and readily releasable pool size at a large hindbrain synapse

Ralf Schneggenburger, Yunyun Han

The localization and density of voltage-gated Ca2+ channels at active zones are essential for the amount and kinetics of transmitter release at synapses. RIM proteins are scaffolding proteins at the active zone that bind to several other presynaptic protei ...
