Computational Neural Modeling of Auditory Cortical Receptive Fields
2019
Frontiers in Computational Neuroscience
Preserved Fulltext
A sound signal was used as input to a model of the cochlea and auditory periphery, which activated or inhibited integrate-and-fire neuron models to represent networks in the primary auditory cortex. ...
This rapid task-related change is believed to be one of the processing strategies utilized by the auditory cortex to selectively attend to one stream of sound in the presence of mixed sounds. ...
