Experience-Dependent Asymmetric Shape of Hippocampal Receptive Fields
We propose a novel parameter, namely, the skewness, or asymmetry, of the shape of a receptive field to characterize two properties of hippocampal place fields. First, a majority of hippocampal receptive fields on linear tracks are negatively skewed, such that during a single pass the firing rate is low as the rat enters the field but high as it exits. Second, while the place fields are symmetri...
متن کاملExperience-dependent, asymmetric expansion of hippocampal place fields.
Theories of sequence learning based on temporally asymmetric, Hebbian long-term potentiation predict that during route learning the spatial firing distributions of hippocampal neurons should enlarge in a direction opposite to the animal's movement. On a route AB, increased synaptic drive from cells representing A would cause cells representing B to fire earlier and more robustly. These effects ...
متن کاملReinterpreting Behavioral Receptive Fields: Lightness Induction Alters Visually Completed Shape
BACKGROUND A classification image (CI) technique has shown that static luminance noise near visually completed contours affects the discrimination of fat and thin Kanizsa shapes. These influential noise regions were proposed to reveal "behavioral receptive fields" of completed contours-the same regions to which early cortical cells respond in neurophysiological studies of contour completion. He...
متن کاملReceptive fields
Drosophila APC has a role in maintaining adherens junctions, and also helps to tether mitotic spindles to the cortex and to orient them in the epithelial plane. In mammalian cells, APC has been implicated in cell migration. APC also helps safeguard the fidelity of chromosome segregation in mitotic cells. Loss of APC’s various functions at the cell periphery may contribute to tumour progression....
متن کاملNMDA Receptor Antagonism Blocks Experience-Dependent Expansion of Hippocampal “Place Fields”
In agreement with theories of sequence learning, hippocampal place representations expand asymmetrically during repeated route following. This behaviorally induced, experience-dependent expression of neuronal plasticity was blocked by the NMDA(R) antagonist CPP, suggesting that it may result from the temporal asymmetry and associative properties of LTP. NMDA(R) antagonism, however, had no effec...
