In subject area: Psychology The receptive field of a retinal ganglion cell is classically defined as the region of the retina or, equivalently, the region of the visual field, where presentation of a stimulus changes the membrane potential of the neuron or (if measured from outside the neuron...
64. As a guiding rule to ensure consistent map definition across participants, we delineated visual field representations using polar angle reversals near the following anatomical landmarks: V1/V2 ventrally on the superior portion of the lingual gyrus and dorsally on the inferior portion of the ...
Most vocabulary size tests in this field assess the breadth of vocabulary knowledge, i.e., how many words are known, rather than the depth of vocabulary knowledge (Read 2000). The Vocabulary Size Test (VST) (Nation and Beglar 2007), designed to measure L1 and L2 learners’ written ...
Receptive field (RF) size and preferred spatial frequency (SF) vary greatly across the primary visual cortex (V1), increasing in a scale invariant fashion with eccentricity. Recent studies reveal that preferred SF also forms a fine-scale periodic map. A
receptive field. Its effect may be to increase or decrease the frequency of firing of the cell. This is symbolized in the diagrams infig. 3.9by the ‘+’ or ‘–’ in the center of the receptive field. The region encircling the center, known as the “surround” provides an antagonistic...
