    A more radical view is that long-term memory is entirely stored as epigenetic, or other changes within the nucleus. Weintraub, S. This form of synaptic plasticity is clearly NMDAR independent as NMDARs require coincident pre- and post-synaptic activity and instead utilizes post-synaptic voltage-dependent calcium channels. These presynaptic modifications can act bi-directionally, to potentiate or depress synaptic efficacy Fioravante and Regehr, ; Regehr, ; Yang and Calakos, Synaptic plasticity and drug addiction.

    Mammalian memory is the result of the interaction of millions of neurons in the brain and their coordinated activity. Candidate mechanisms for.It is unclear whether the new connections established by learning involve de novo synaptogenesis or the conversion of silent synapses to an active state, or how either of these mechanisms might be impervious to protein synthesis inhibition see below.

    One principle about learning and memory derived from studies of this simple animal, and this principle holds true in our brains as well, is that learning.Each soma gives rise to one axon, which has a smaller diameter than the numerous dendrites.

    Hebb postulated that “increments in synaptic efficacy occur during learning when the firing of one neuron repeatedly produces firing in another.For example, he noted that the DNA of Drosophila appeared to lack cytosine methylation, but fruit flies nevertheless exhibit long-term memory.

    Therefore, after the tetanus, the transmitter released from the presynaptic neuron by a test stimulus will bind to a greater number of receptors on the postsynaptic neuron.

    Cell assemblies are essentially a collection of activated synapses and the sufficiently strong activation of these synapses causes biochemical changes in the neurons of the cell assembly.
