Receptive fields have been identified for neurons of the auditory system, the somatosensory system, and the visual system. The term receptive field was first used by Sherrington in 1906 to describe the area of skin from which a scratch reflex could be elicited in a dog. Ver mais The receptive field, or sensory space, is a delimited medium where some physiological stimuli can evoke a sensory neuronal response in specific organisms. Complexity of the receptive field ranges from the … Ver mais In the somatosensory system, receptive fields are regions of the skin or of internal organs. Some types of mechanoreceptors have large receptive fields, while others have smaller ones. Ver mais The term receptive field is also used in the context of artificial neural networks, most often in relation to convolutional neural networks (CNNs). So, in a neural network context, the … Ver mais • Receptive Fields Tutorial Ver mais The auditory system processes the temporal and spectral (i.e. frequency) characteristics of sound waves, so the receptive fields of … Ver mais In the visual system, receptive fields are volumes in visual space. They are smallest in the fovea where they can be a few minutes of arc like … Ver mais • Visual system • Reflexogenic zone • Spatiotemporal receptive field • Spectro-temporal receptive field Ver mais Web22 de jul. de 2015 · Previous theoretical and experimental studies have demonstrated tight relationships between natural image statistics and neural representations in V1.
