Shaping synaptic learning by the duration of postsynaptic action potential in a new STDP model. [PDF]

PLoS ONE, 2014
Single spikes and their timing matter in changing synaptic efficacy, which is known as spike-timing-dependent plasticity (STDP). Most previous studies treated spikes as all-or-none events, and considered their duration and magnitude as negligible.

Role of Amorphous Phases in Mixed Conduction of Conjugated Regioblock Copolymers for Organic Electrochemical Synaptic Transistors

Advanced Materials, EarlyView.
Critical roles of amorphous and crystalline phases in polymer‐based mixed ionic‐electronic conductors for organic electrochemical synaptic transistors using conjugated regioregular‐block‐regiorandom copolymers are demonstrated. Amorphous phases contribute to gradual polaron formation and strong ion trapping by bipolarons, leading to improved synaptic ...

Differential role of pre- and postsynaptic neurons in the activity-dependent control of synaptic strengths across dendrites.

PLoS Biology, 2019
Neurons receive a large number of active synaptic inputs from their many presynaptic partners across their dendritic tree. However, little is known about how the strengths of individual synapses are controlled in balance with other synapses to ...
