Modulation of SK Channel Trafficking by Beta Adrenoceptors Enhances Excitatory Synaptic Transmission and Plasticity in the Amygdala [PDF]

open access: yes, 2008
Emotionally arousing events are particularly well remembered. This effect is known to result from the release of stress hormones and activation of beta adrenoceptors in the amygdala. However, the underlying cellular mechanisms are not understood.

Higher‐Order Temporal Dynamics in Complementary Charge Trap Memristor for High‐Dimensional Reservoir Computing

open access: yesAdvanced Functional Materials, EarlyView.
A complementary charge‐trap memristor (CoCTM) featuring a unique current transient with tunable overshoot‐relaxation dynamics is introduced for high‐resolution reservoir computing. By leveraging higher‐order temporal dynamics from engineered trapping layers, the device generates multiple output states from a single input, forming rich, high‐dimensional

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

open access: yesAdvanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...

Delay-independent stability in bidirectional associative memory networks [PDF]

open access: yes, 1994
It is shown that if the neuronal gains are small compared with the synaptic connection weights, then a bidirectional associative memory network with axonal signal transmission delays converges to the equilibria associated with exogenous inputs to the ...
