| 2 | Synaptic plasticity |
| The term synaptic plasticity refers to the variability of the strength of a signal transmitted through a synapse. Synaptic plasticity is part of the Hebbian theory about the neurochemical foundations of memory and learning. Two known molecular mechanisms for synaptic plasticity were revealed by ... | |
| 3 | Synapse |
| the other by diffusion. This gap is sometimes called the synaptic cleft. Such synapses are asymmetric both in structure and in how they operate. Only the so-called pre-synaptic neuron secretes the neurotransmitter, which binds to receptors facing into the synapse from the post-synaptic cell. The pre ... | |
| 4 | Reuptake |
| Reuptake is the reabsorption of a neurotransmitter by the molecular transporter of a pre-synaptic neuron after it has performed its function of transmitting a neural impulse. See also : "Monoamine transporter ... | |
| 5 | Synaptic vesicle |
| In a neuron, synaptic vesicles , also called neurotransmitter vesicles , store the various... the synaptic cleft of a synapse. They are essential for the propagation of nerve impulses between neurons and are constantly recreated by the cell. Synaptic vesicles are made of a bilipid layer in which ... | |
| 6 | Long-term depression |
| Long-term depression (LTD) is a weakening of a synapse that lasts from hours to days. It results from either strong synaptic stimulation (as in the cerebellum) or to persistent weak synaptic stimulation (as in the hippocampus). Compare to long-term potentiation. LTD is thought to result from ... | |

| 8 | Axon hillock |
| The axon hillock is the anotomical part of a neuron that connects the cell body to the axon. It is attributed as the place where EPSPs from numerous synaptic inputs on the dendrites or cell body accumulate. If the accumulated potential reaches the threashold, an action potential propagates through ... | |
| 9 | Spike timing dependent plasticity |
| Spike timing dependent plasticity (STDP) is a form of synaptic plasticity naturally occurring in neurons. The STDP is a highly non-linear phenomenon. It is believed to strengthen synapses that are activated within 20-40 ms before a postsynaptic spike, and to weaken those that are activated within ... | |
| 10 | Hebbian theory |
| Hebbian theory describes a basic mechanism for synaptic plasticity wherein an increase in synaptic efficacy arises from the presynaptic cell's repeated and persistent stimulation of the postsynaptic cell. It was introduced by Donald Hebb in 1949 and states that: Let us assume that the persistence ... | |
| 11 | Donald Olding Hebb |
| Donald Olding Hebb (1904-1985) was an influential psychologist, particularly in the area of neuropsychology, where he sought to understand how the function of neurons contributed to psychological processes such as learning. His most famous work involved the rule of covariation of synaptic weight ... | |
| 12 | Pinealocyte |
| Pinealocytes are the main cells of the pineal gland. They produce and secrete melatonin. Pinealocytes have an organelle called synaptic ribbon , this is considered to be a specific marker for pinealocytes. Some of the enzymes of the pinealocytes include 5-HT N-acetyl transferase and 5-hydroxyindole ... | |

| 15 | Agmatine |
| Agmatine ((4-aminobutyl)guanidine, NH 2-CH 2-CH 2-CH 2-CH 2-NH-C(-NH 2)(=NH)) is the decarboxylation product of the amino acid arginine and is an intermediate in polyamine biosynthesis. It is discussed as a putative neurotransmitter. It is synthesized in the brain, stored in synaptic vesicles ... |
