Will Sullivan, Smithsonian Magazine, 10 May 2024 Instead of looking how each neuron and synapse operates in the brain and trying to emulate that from the bottom up, Gonzalez says, the his team’s approach involved implementing key performance features of the brain. IEEE Spectrum, 8 May 2024 ...

Understanding how information is processed in the brain requires identification of the nerve cells comprising a neuronal network, definition of the intrinsic properties of the neurons, their synaptic connectivity pattern and knowledge about how the synapses between the individual neurons operate. Revealing ...
Synaptic Cleft | Definition, Function & Activity from Chapter 12/ Lesson 26 65K The synaptic cleft is vital to how information in the brain is relayed from one neuron to another. Learn the definition and all about how the synapse works. ...
This definition excludes synapses that are silent because of branch point failures in the conduction of the action potential from the soma to the presynaptic terminal. It also excludes synapses that are formed de novo during development or following some experimental manipulation (e.g., lesions). ...

In the adult hippocampus, synapses are constantly formed and eliminated1,2. However, the exact function of synapse elimination in the adult brain, and how it is regulated, are largely unknown. Here we show that astrocytic phagocytosis3 is important for maintaining proper hippocampal synaptic connecti...
Although postsynaptic LTP is generally considered to be more widely distributed, presynaptic LTP is expressed in some of the most abundant synapses in brain, including hippocampal mossy fiber synapses Weisskopf et al. 1994, Huang et al. 1994, corticothalamic and corticostriatal synapses Castro-Ala...
Abraham Abstract | Synaptic plasticity is a key component of the learning machinery in the brain. It is vital that such plasticity be tightly regulated so that it occurs to the proper extent at the proper time. Activity-dependent mechanisms that have been collectively termed metaplasticity have ...
In the brain, learning is achieved through the ability of synapses to reconfigure the strength by which they connect neurons (synaptic plasticity). In promising solid-state synapses called memristors, conductance can be finely tuned by voltage pulses and set to evolve according to a biological learn...
