Dopamine Neurons Represent Reward But Not Aversiveness
Speed selectivity was characterized by the maximum response, optimum speed, upper cutoff speed, response to slow movement, and tuning width. Direction ...
mediated myelin plasticity and its role in neural synchronization - eLifeThe neuronal representation of time on the sub-second timescale is a fundamental requisite for the perception of time-varying sensory sti- muli, ... A Highly Effective and Robust Membrane Potential Driven ...These notes expand on various aspects of the computational model. The first note recapitulates the mathematical theory of temporal difference (TD) learning ... Distributed Synchrony of Spiking Neurons in a Hebbian Cell AssemblySpontaneous in vivo neuronal firing rates span 4?5 orders of magnitude, from below 0.001 to 50 spikes/s and above. Such heterogeneity is found ... temporal neurons Speed and direction selectivity of macaque middleThe bottom time axis depicts the neuron's output spikes in the response to the input pattern. (B) Voltage trace (left) and synaptic weights ( ... Unsigned temporal difference errors in cortical L5 ... - bioRxivWe discuss how biological parameters such as dwelling times at states, neuronal firing rates and neuromodulation relate to the delay discounting. Learning Precisely Timed Spikes - Harvard UniversityChanges to either the spatial or temporal frequency will influence their firing rates. A neuron truly encoding image speed will respond to a particular speed, ... Learning predictive cognitive maps with spiking neurons during ...First we have a look at the TD formalism in continuous time. Next, we show how spiking neurons can implement a critic, to represent and learn ... measuring the visual speed analyzing properties of primate MT ...We further devised a Q-learning model incorporating belief state inference, which could simultaneously produce phasic and ramping TD error, ... Reinforcement Learning Using a Continuous Time Actor-Critic ...After these changes, average firing rate of actor neurons and critic neurons are around. 50Hz and 70Hz respectively, which are in the gamma ... TD models of reward predictive responses in dopamine neuronsAbstract. This article focuses on recent modeling studies of dopamine neuron activity and their influence on behavior. Activity of midbrain. TDSTDP - bioRxivThe total signal received by dopaminergic neurons is always the difference between time t and t - ?DA. DA magnitude is also a form of TD but ...
