When Branch-Local Shunting Helps: A Gain-Load-Alignment Principle for Dendritic E/I Networks
Houman Safaai, Maceo Richards, Naeem Khoshnevis +1
Biological neurons combine excitatory and inhibitory (E/I) activity on branched dendrites through shunting, in which inhibition divisively attenuates excitation. Whether this impro…
Synaptic clustering emerges from learning and supports covariance discrimination
Ilenna Simone Jones, Maceo Richards, Houman Safaai +2
Functional synapse clusters (FSCs) are synapses with correlated presynaptic activity that are colocalized on the same neuronal dendritic branch. FSCs have been observed after learn…
Shunting Inhibition and Dendritic Branching Shape Local Credit Assignment
Houman Safaai, Maceo Richards, Bernardo L. Sabatini
Biological neurons assign credit across branching dendrites, where synaptic drive, conductance, local voltage, and somatic teaching signals interact to shape plasticity. We study c…
Conditioned Direct Feedback Alignment via Activity and Error Geometry
Houman Safaai, Varun Reddy, Bernardo L. Sabatini
Direct feedback alignment (DFA) trains hidden layers with fixed random projections of the output error, avoiding the transposed-weight backward pass of backpropagation (BP). We stu…
ALIGN: Adversarial Learning for Generalizable Speech Neuroprosthesis
Zhanqi Zhang, Shun Li, Bernardo L. Sabatini +2
Intracortical brain-computer interfaces (BCIs) can decode speech from neural activity with high accuracy when trained on data pooled across recording sessions. In realistic deploym…
