A Heterosynaptic Spiking Neural System for the Development of Autonomous Agents
… other hebbian-based plasticity rules. The new heterosynaptic architecture presented, explicitly abstracts the modulation of complex biochemical mechanisms into a simplified mechanism that is suitable for the engineering of artificial systems with low computational complexity. Neurons work by …

A Three-Molecule Model of Structural Plasticity: the Role of the Rho family GTPases in Local Biochemical Computation in Dendrites
… synapse-specific signals (through Cdc42) and heterosynaptic signals (through Rac1). </p><p>The next set of experiments detail one the potential consequences of heterosynaptic Rac1 signaling. The spread of Rac1 activity out of the stimulated spine was found to be necessary for lowering the …

Long Term Plasticity Induced by Intracellular Tetanization in the Rat Auditory Cortex
… and lacks mechanisms for synaptic competition. Heterosynaptic plasticity may solve these problems by complementing plasticity at synapses that were active during the induction, with opposite-sign changes at non-activated synapses. In visual cortex a potential candidate mechanism for …

Thalamocortical forward modulation in the auditory cortex
… the capability of forward suppression through heterosynaptic thalamocortical inputs. Forward suppression of tones by ESMGBv was comparatively weaker than forward suppression of ESMGBv by tone stimulus. The period of complete suppression in the cortex for all stimuli was approximately 100 ms. …

Heterogenous Change in Neuronal Bursts Following Recovery from Activity Silencing
Silencing of activity in hippocampal neuronal cultures was used to study how dynamic neuronal activity achieves a state of homeostasis, using calcium imaging to detect neuronal firing patterns. Recovering cultures were found to display abnormal activity patterns after 48hrs of exposure to …
