What is receptive field in psychology?
The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections.
What is the best definition of the receptive field?
the best definition of the “receptive field” of an afferent neuron. The area of the body that, when stimulated, leads to activity in that particular afferent neuron.
What is a receptive field example?
For example, it could be a hair in the cochlea or a piece of skin, retina, or tongue or other part of an animal’s body. Receptive fields have been identified for neurons of the auditory system, the somatosensory system, and the visual system.
What are the different types of receptive field?
Receptive field subregions: The area within the receptive field is subdivided into two regions, center and surround. There are two primary types of ganglion cell receptive fields: ON center/OFF surround cell: Flashing small bright spot in the center subregion increases the cell’s response.
What is a receptive field quizlet?
Receptive field. – Receptive field – region of a sensory surface that, when stimulated, causes a change in the firing rate of a neuron that “monitors” that region of the surface; the receptive field of an RGC is the region of the retina occupied by the photoreceptors to which the RGC is connected.
What is a receptive field for dummies?
The receptive field is a term originally coined by Sherrington (1906) to describe an area of the body surface where a stimulus could elicit a reflex.
What is the receptive field of a sensory neuron quizlet?
Somatic sensory and visual neurons are activated by stimuli that fall within a specific physical area known as the neuron’s “receptive field.”
What does the receptive field of a visual cell refer to quizlet?
The receptive field of a visual cell refers to the. Retinal area that affects the firing of the cell. The structure of the eye that absorbs light processes images and sends visual information to the brain. Retina.
What is receptive field in deep learning?
What is the receptive field in deep learning? Similarly, in a deep learning context, the Receptive Field (RF) is defined as the size of the region in the input that produces the feature[3]. Basically, it is a measure of association of an output feature (of any layer) to the input region (patch).
What is receptive field quizlet?
What is the shape of a receptive field of a ganglion cell?
slightly elliptical
All classes of ganglion cells tended to have slightly elliptical receptive field centres. Major axes of over half of all receptive fields were oriented within 20 degrees of horizontal.
What is meant by a receptive field in CNN?
Definition So what actually is the receptive field of a convolutional neural network? Formally, it is the region in the input space that a particular CNN’s feature is affected by. More informally, it is the part of a tensor that after convolution results in a feature.
What is a visual receptive field?
Definition. The term receptive field refers to the region of visual space where changes in luminance influence the activity of a single neuron. Also known as the classical receptive field (CRF).
What is visual receptive field?
What is a receptive field in deep learning?
What is a receptive field in psychology?
(Show more) receptive field, region in the sensory periphery within which stimuli can influence the electrical activity of sensory cells.
Where did the term receptive field come from?
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. In 1938, Hartline started to apply the term to single neurons, this time from the frog retina.
What is receptive field electrophysiology?
A receptive field is often functionally characterized by electrophysiological experiments. During these experiments, a certain area of the body is stimulated: e.g., a certain part of the visual field is illuminated, or a certain area of the skin is haptically stimulated (Fig. 1), etc..
How are receptive fields organized in the brain?
There is a serial and hierarchical organization of receptive field properties. Each sensory modality is composed of multiple brain areas. As one proceeds from receptor to thalamus to the primary sensory cortex and higher cognitive areas of the brain, receptive fields demonstrate increasingly complex stimulus requirements.
