Sparse high-dimensional decomposition of non-primary auditory cortical receptive fields
by Shoutik Mukherjee, Behtash Babadi, Shihab Shamma
Characterizing neuronal responses to natural stimuli remains a central goal in sensory neuroscience. In auditory cortical neurons, the stimulus selectivity of elicited spiking activity is summarized by a spectrotemporal receptive field (STRF) that relates neuronal responses to the stimulus spectrogram. Though effective in characterizing primary auditory cortical responses, STRFs of non-primary auditory neurons can be quite intricate, reflecting their mixed selectivity. Читать дальше...
