The cell adhesion molecule Neuroligin2 (NL2) is localized selectively at GABAergic synapses, where it interacts with the scaffolding protein gephyrin in the post-synaptic density. However, the role of this interaction for formation and plasticity of GABAergic synapses is unclear. Here, we demonstrate that endogenous NL2 undergoes proline-directed phosphorylation at its unique S714-P consensus s...

Multiple studies have reported the observation of electro-synaptic response in different metal/insulator/metal devices. However, most them analyzed large (>1 µm2) devices that do not meet integration density required by industry (1010 devices/mm2). Some emploied a scanning tunneling microscope (STM) to explore nano-synaptic materials, but this setup there is nanogap between insulator and one me...

DYT1 early-onset generalized torsion dystonia (DYT1 dystonia) is an inherited movement disorder caused by mutations in one allele of DYT1 (TOR1A), coding for torsinA. The most common mutation is a trinucleotide deletion (ΔGAG), which causes a deletion of a glutamic acid residue (ΔE) in the C-terminal region of torsinA. Although recent studies using cultured cells suggest that torsinA contribute...

introduction: many studies have shown that amygdala kindling produces synaptic potentiation by induction of changes in the neuronal electrophysiological properties and inward currents both in epileptic focus and in the areas which are in connection with the epileptic focus and have important role in seizure development and progression such as hippocampal ca1 region. however, cellular mechanisms...

Cannabinoid (CB) signaling is a well established regulator of synaptic transmission. Recent work demonstrated that CB release is necessary for the induction of inhibitory synaptic plasticity. In primary visual cortex (V1) CB receptors are present throughout life, though their level of expression is developmentally regulated. In the input layer of V1 (layer 4, L4) these receptors show low levels...

The dorsal motor nucleus of the vagus (DMV) is a key integrative point of the parasympathetic neuronal network localized in the dorsal vagal complex. Activity of neurons in the DMV is closely regulated by synaptic inputs, and regulation of excitatory and inhibitory synapsis by transient receptor potential vanilloid type 1 (TRPV1) has been demonstrated. Activation of TRPV1 by heat, protons, endo...

A balance between excitatory and inhibitory synaptic currents is thought to be important for several aspects of information processing in cortical neurons in vivo, including gain control, bandwidth and receptive field structure. These factors will affect the firing rate of cortical neurons and their reliability, with consequences for their information coding and energy consumption. Yet how bala...

1. Post-synaptic responses to acetylcholine (ACh) released from nerve terminals and from iontophoretic micropipettes were investigated in skeletal muscle fibres of the snake. Each fibre has a compact end-plate consisting of fifty to seventy synaptic boutons. The fibres were voltage clamped, and synaptic currents were recorded from visually identified end-plates. 2. When acetylcholinesterase (AC...
