Postsynaptic density
The postsynaptic density (PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an electron-dense region at the membrane of a postsynaptic neuron. wikipedia.org

Postsynaptic potential
Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. These are collectively referred to as postsynaptic receptors, since they are on the membrane of the postsynaptic cell. wikipedia.org

Excitatory postsynaptic potential
In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a result wikipedia.org

What makes synapses stay "fixed"? What makes synapses not move or pre- and postsynaptic cells neither touch nor move away from each other? I mean the synaptic cleft is a gap between the pre- and postsynaptic cells tha...
Synapses are held together by adhesion molecules, like cadherins and neuroligins/neurexins, so they aren't just loose adjacent membrane, they are securely anchored in place. The adhesion molecules serve both a structural and regulatory role, being important for synapse formation and plasticity. Miss...

Inhibitory postsynaptic potential
The opposite of an inhibitory postsynaptic potential is an excitatory postsynaptic potential (EPSP), which is a synaptic potential that makes a postsynaptic An electric current that changes the postsynaptic membrane potential to create a more negative postsynaptic potential is generated, i.e. the postsynaptic wikipedia.org

What is the perisomatic region of a neuron? In the scholarpedia page on interneurons I encountered the following passage: > The **perisomatic domain** is responsible for the summation of postsynaptic potentials arriv...
In cortical GABAergic cells with local axonal projections, the perisomatic region is defined as that part of the plasma membrane including the proximal dendrites, the cell body and the axon initial segment (Zabó _et al_., 2010). **Reference** **-** Zabó _et al_., _Eur J Neurosci_ (2010); **31** (12)...

What is meant by the term synaptic targeting? I am studying whether a protein interacts with the mitochondria in the synapses of neurons and I have come across the term "synaptic targeting". I am reading this paper807...
PSD-95 is a protein located in the post-synaptic region inside a cell. In fact it's named for this, "post synaptic density-95" referring to the dense appearance of the post synaptic area on an EM microscope and this protein's presence there. "Synaptic targeting" in this context refers to how that pr...

Definition of synaptic strength The canonical definition of action potentials found in textbooks states that action potentials are all alike in shape. From techniques such as spike sorting which are used to attribute ...
> Synaptic strength is defined as the average amplitude of postsynaptic potential evoked following a presynaptic action potential. It can be influenced by both presynaptic (for example: number of vesicles/concentration of neurotransmitter per vesicle) and postsynaptic effects (for

Excitatory synapse
Responses of the postsynaptic neuron When neurotransmitters reach the postsynaptic neuron of an excitatory synapse, these molecules can bind to two possible types of receptors that are clustered in a protein-rich portion of the postsynaptic cytoskeleton called the Postsynaptic density (PSD). wikipedia.org
