5-Hydroxytryptamine 5HT2C Receptors Form a Protein Complex with N-Methyl-d-aspartate GluN2A Subunits and Activate Phosphorylation of Src Protein to Modulate Motoneuronal Depolarization*
Background: 5-Hydroxytryptamine (5HT) modulates N-methyl-d-aspartate (NMDA) depolarization. Results: 5HT2C co-immunoprecipitates with GluN2A and enhances NMDA motoneuronal depolarization throughExpand

Properties of ibogaine and its principal metabolite (12-hydroxyibogamine) at the MK-801 binding site of the NMDA receptor complex
The putative anti-addiction alkaloid ibogaine and its principal metabolite 12-hydroxyibogamine appear to act at the (+)-5 methyl-10,11,dihydro-5H- dibenzo[a,d]cycloheten-5-10-imine maleate (MK-801)Expand

Mechanisms involved in the metabotropic glutamate receptor‐enhancement of NMDA‐mediated motoneurone responses in frog spinal cord
The metabotropic glutamate receptor (mGluR) agonist trans‐(±)‐1‐amino‐1,3‐cyclopentanedicarboxylic acid (trans‐ACPD) (10–100 μM) depolarized isolated frog spinal cord motoneurones, a processExpand

The Number of Components of Enhancement Contributing to Short-Term Synaptic Plasticity at the Neuromuscular Synapse during Patterned Nerve Stimulation Progressively Decreases As Basal Release
Presynaptic short-term plasticity (STP) dynamically modulates synaptic strength in a reversible manner on a timescale of milliseconds to minutes. For low basal vesicular release probability (prob0),Expand

Voltage-gated calcium currents in whole-cell patch-clamped bullfrog dorsal root ganglion cells: effects of cell size and intracellular solutions
Acutely dissociated bullfrog dorsal root ganglion (DRG) cells could be divided into two classes by measurement of cell capacitance. A bimodal distribution of cell capacitance was found and a value ofExpand
