Rectilinear Edge Selectivity Is Insufficient to Explain the Category Selectivity of the Parahippocampal Place Area
The parahippocampal place area (PPA) is one of several brain regions that respond more strongly to scenes than to non-scene items such as objects and faces. The mechanism underlying this scene-preferential response remains unclear. One possibility is that the PPA is tuned to low-level stimulus features that are found more often in scenes than in less-preferred stimuli. Supporting this view, Nas...
متن کاملDifferential connectivity within the Parahippocampal Place Area
The Parahippocampal Place Area (PPA) has traditionally been considered a homogeneous region of interest, but recent evidence from both human studies and animal models has suggested that PPA may be composed of functionally distinct subunits. To investigate this hypothesis, we utilize a functional connectivity measure for fMRI that can estimate connectivity differences at the voxel level. Applyin...
متن کاملThe `Parahippocampal Place Area' Responds Selectively to High Spatial Frequencies
Defining the exact mechanisms by which the brain processes visual objects and scenes remains an unresolved challenge. Valuable clues to this process have emerged from the demonstration that clusters of neurons (‘‘modules’’) in inferior temporal cortex apparently respond selectively to specific categories of visual stimuli, such as places/scenes. However, the higher-order ‘‘category-selective’’ ...
متن کاملThe Parahippocampal Place Area Recognition, Navigation, or Encoding?
The parahippocampal place area (PPA) has been demonstrated to respond more strongly in fMRI to scenes depicting places than to other kinds of visual stimuli. Here, we test several hypotheses about the function of the PPA. We find that PPA activity (1) is not affected by the subjects' familiarity with the place depicted, (2) does not increase when subjects experience a sense of motion through th...
متن کاملCorrespondence: Reply to ‘DNA shape is insufficient to explain binding'
Transcription factors (TFs) are DNA-binding proteins that regulate gene expression. Sequence-specific TFs recognize DNA via specific amino acid-base hydrogen bonds and contacts that read local DNA shape1. Studying base and shape readout modes of TFs in vivo has been challenging due to technical issues associated with current approaches for mapping TF-binding sites (TFBSs). We recently introduce...
