    This study reveals distinct zones within dolphin visual and auditory cortices, each generating unique evoked potentials. These findings suggest specialized processing areas for sensory information in dolphins.

    Area of Science:

    • Neuroscience
    • Sensory Processing
    • Comparative Neurology

    Context:

    • Investigating the neurophysiological basis of sensory perception in cetaceans.
    • Understanding the functional organization of dolphin cortical areas.

    Purpose:

    • To characterize evoked potentials in dolphin visual and auditory cortices.
    • To identify distinct functional zones within these sensory areas.

    Summary:

    • Evoked potentials were recorded in response to afferent stimuli in dolphin visual and auditory cortical areas.
    • Both cortical areas exhibit zonal differentiation, with distinct evoked potential forms and temporal parameters.
    • These zones are proposed as multiple projection areas for the respective sensory analysers.
