Potassium conductance dynamics confer robust spike-time precision in a neuromorphic model of the auditory brain stem.
A fundamental question in neuroscience is how neurons perform precise operations despite inherent variability. This question also applies to neuromorphic engineering, where low-power microchips emulate the brain using large populations of diverse silicon neurons. Biological neurons in the auditory pathway display precise spike timing, critical for sound localization and interpretation of comple...

LEARNING IN SILICON: A NEUROMORPHIC MODEL OF THE HIPPOCAMPUS John Vernon Arthur Supervisor: Kwabena Boahen The human brain is the most complex computing structure in the known universe; it excels at many tasks that digital computers perform poorly, such as learning input patterns and later retreiving themwith only a part of the original patterns as input, realizing associative memory. Our brain...
متن کاملSubthreshold K+ channel dynamics interact with stimulus spectrum to influence temporal coding in an auditory brain stem model.
Neurons in the auditory brain stem encode signals with exceptional temporal precision. A low-threshold potassium current, IKLT, present in many auditory brain stem structures and thought to enhance temporal encoding, facilitates spike selection of rapid input current transients through an associated dynamic gate. Whether the dynamic nature of IKLT interacts with the timescales in spectrally ric...
متن کاملAsymmetric Excitatory Synaptic Dynamics Underlie Interaural Time Difference Processing in the Auditory System
Low-frequency sound localization depends on the neural computation of interaural time differences (ITD) and relies on neurons in the auditory brain stem that integrate synaptic inputs delivered by the ipsi- and contralateral auditory pathways that start at the two ears. The first auditory neurons that respond selectively to ITD are found in the medial superior olivary nucleus (MSO). We identifi...
