Before revision:  Finally, we show that firing patterns displayed by neurons in the ventral pallidum  , a basal ganglia structure playing a crucial role in motivated behaviors , are similar to the responses of neuronsin recurrent neural networks trained in similar conditions. Similarly to the pallidum neurons, artificial neural nets contain two different classes of neurons, tuned to reward and punishment.
After revision:  Finally, we show that firing patterns displayed by neurons in the ventral pallidum , a basal ganglia structure playing a crucial role in motivated behaviors . We show that, similarly to real neurons, recurrent networks with motivation are composed of two oppositely-tuned classes of neurons, tuned to reward and punishment.
