[GOC:jl, MeSH:D009435] EOG8W10TV GO:0043197 1/189 dendritic spine cellular_component "Protrusion from a dendrite. Spines are specialised subcellular compartments involved in the synaptic transmission. They are linked to the dendritic shaft by a restriction. Because of their bulb shape, they function as a biochemical and an electrical compartment. Spine remodeling is though to be involved in synaptic plasticity." [GOC:nln] EOG8W10TV GO:0060079 1/189 excitatory postsynaptic potential biological_process "A process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential." [GOC:dph, GOC:ef] EOG8W10TV GO:0007632 1/189 visual behavior biological_process "The behavior of an organism in response to a visual stimulus." [GOC:jid, GOC:pr] EOG8W10TV GO:0030425 1/189 dendrite cellular_component "A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body."

[GOC:ai] EOG8W10TV GO:0014069 1/189 postsynaptic density cellular_component "The postsynaptic density is a region that lies adjacent to the cytoplasmic face of the postsynaptic membrane at excitatory synapse. It forms a disc that consists of a range of proteins with different functions, some of which contact the cytoplasmic domains of ion channels in the postsynaptic membrane. The proteins making up the disc include receptors, and structural proteins linked to the actin cytoskeleton. They also include signalling machinery, such as protein kinases and phosphatases. The postsynaptic density may be part of a neuron or a muscle cell or a glial cell."
