Global presynaptic facilitation
Neural facilitation, also known as paired-pulse facilitation (PPF), is a phenomenon in neuroscience in which postsynaptic potentials (PSPs) (EPPs, EPSPs or IPSPs) evoked by an impulse are increased when that impulse closely follows a prior impulse. PPF is thus a form of short-term synaptic plasticity. The mechanisms underlying neural facilitation are exclusively pre-synaptic; broadly speaking, PPF arises due to increased presynaptic Ca concentration leading to a great… WebSep 29, 2014 · Nigral dopamine loss induces a global upregulation of presynaptic dopamine D1 receptor facilitation of the striatonigral GABAergic output Shengyuan Ding, Li Li, and Fu-Ming Zhou Department of Pharmacology, University of Tennessee College of Medicine, Memphis, Tennessee Submitted 29 September 2014; accepted in final form …

WebPresynaptic inhibition by post-synaptic cells. Although we think of neuronal signalling as one way, that's not entirely true. Post-synaptic cells have mechanisms to communicate with the pre-synaptic cell, and this can include inhibiting that cell. Endocannabinoids are one mechanism: they are released by the post-synaptic cell and can reduce pre ... WebPennpoint Consulting Group, LLC. May 2012 - Present11 years. Greater Atlanta Area.
